Is making a terrarium really good for your mind? What science (and people) say
Does making a terrarium really benefit the mind? What science says (and what people report)
A friend told me something I'll never forget: after being diagnosed with Parkinson's at a young age, he started doing precise handiwork. Among these, building a terrarium. He told me that as he layered peat, charcoal, and gravel, his hands found a calm that eluded him during the day. He didn't get cured, it's not therapy. But in those minutes, the art of tranquility—as he called it—allowed him to control his movements better.
In this in-depth guide, you will understand what scientific research truly says about the benefits of indoor gardening and terrarium-making for those living with stress, anxiety, Parkinson's, ADHD, dementia, or simply looking to slow down. We will examine what can and cannot be honestly stated, and how to start in practice, even with small kits.
Building a terrarium is a manual, slow, and creative activity that combines contact with living plants, fine motor skills, and soft attention: scientific research on indoor gardening shows positive short-term effects on perceived stress, state anxiety, and some physiological indicators, but it is not clinical therapy.
Key Points
- Psychological benefits — Terrarium-making can reduce perceived stress and state anxiety, promoting mindfulness and psychophysical well-being.
- Scientific evidence — Studies on indoor gardening and horticultural therapy support positive effects on mood and concentration, with specific research on terrariums still in the preliminary phase.
- Inclusive activity — It can be a meaningful activity for people with Parkinson's, anxiety, ADHD, dementia, or for those seeking a break from digital life, always with due precautions.
- Not a therapy — It is crucial to distinguish terrarium-making from clinical treatment; it does not replace professional medical or psychological care.
- Mindful practice — The act of assembling and caring for a terrarium fosters fine motor skills, concentration, and a sense of accomplishment, improving attention.

What happens in your body and mind when you build a terrarium
When you dedicate yourself to creating a terrarium, your body and mind enter a specific mode, characterized by calm and focused attention, which can generate a deep sense of well-being.
This process involves several psychophysiological mechanisms that contribute to reducing stress and improving concentration.
Slow gestures requiring attention: Kaplan's "soft fascination"
The act of assembling a terrarium is inherently slow and methodical. Each step, from arranging the drainage layer to choosing plants, requires a delicate precision that draws the mind away from daily worries.
This phenomenon is described by Stephen Kaplan's Attention Restoration Theory (ART) (1995), which refers to "soft fascination." This is an involuntary attention, captured by non-threatening natural stimuli, that allows the mind to rest and regenerate, without the effort required by directed attention.
The delicate work with small plants, the choice of stones or moss, are all elements that promote this form of restorative attention, allowing the brain to recover cognitive energy.
Busy hands, slowing mind: fine motor skills and parasympathetic system activation
Engaging in activities that require fine motor skills, such as handling small plants or positioning decorative elements, stimulates brain areas related to coordination and precision. This not only improves manual dexterity but can also have a calming effect on the nervous system.
When we focus on manual tasks, the activity of the sympathetic nervous system (responsible for the "fight or flight" response) tends to decrease, giving way to the activation of the parasympathetic nervous system, which promotes relaxation and rest. This translates into a reduction in heart rate and muscle tension, contributing to a general sense of tranquility.
Roger Ulrich's Stress Recovery Theory (1991) suggests that exposure to natural environments or natural elements, such as plants, can trigger physiological recovery from stress, reducing indicators like blood pressure and muscle tension.
Why it works for many people (and for whom it might not)
The combination of soft attention and parasympathetic activation makes terrarium-making a potentially beneficial activity for many. It works well for those seeking a hobby that offers an escape from digital stress, for those who appreciate manual work, and for those who find comfort in caring for something alive.
However, it might not be ideal for everyone. People with specific allergies to soil or plants, or those who find the required precision frustrating, might not derive the same benefits. It's always a matter of personal preference and how the activity aligns with one's needs and abilities.
The science behind calm
Kaplan's Attention Restoration Theory (ART) (1995) and Ulrich's Stress Recovery Theory (1991) are pillars in the study of nature's benefits on the mind. ART explains how exposure to natural contexts, even miniature ones like a terrarium, can restore attention capacity. The Stress Recovery Theory, on the other hand, highlights how observing natural elements quickly reduces physiological indicators of stress, such as blood pressure and heart rate.
What scientific research truly says (and where it stops)
Scientific research on indoor gardening and horticultural therapy offers an interesting picture of mental health benefits, but it is crucial to understand the limitations and specificities of the evidence, especially when it comes to terrariums.
The most robust evidence comes from broader studies, while specific studies on terrarium-making are still in an exploratory phase.
Studies on indoor gardening and stress: what they found
Numerous studies have explored the impact of indoor gardening on psychological well-being. A meta-analysis by Soga, Gaston, and Yamaura (2017) published in Preventive Medicine Reports examined the effect of contact with nature on mental health, finding a significant effect with an effect size of 0.42 (95% CI 0.36–0.48) on various well-being outcomes.
More recently, a systematic review and meta-analysis by Lu, Liu, and Xu (2023) in Frontiers in Psychology, which included 31 studies and 1,036 participants, found a significant reduction in stress and an improvement in psychological indicators with an SMD of −0.73 for indoor gardening interventions.
Specific studies on indoor plant activities
Delving into activities with plants in indoor environments, a study by Lee, Lee, and Park (2015) in the Journal of Physiological Anthropology compared 15 minutes of indoor repotting with a computer task. Participants in the gardening group showed significantly lower diastolic blood pressure and sympathetic activity, indicating greater physiological relaxation.
Another pilot RCT study by Odeh, Diehl, and Nixon (2022) published in PLOS ONE, conducted on 32 women, found that 8 sessions of indoor gardening led to significant improvements in POMS (Profile of Mood States), PSS (Perceived Stress Scale), and BDI-II (Beck Depression Inventory-II) scores.
Studies on anxiety and clinical depression
Regarding more specific conditions, research becomes more cautious. A review by Wood, Barton, and Wicks (2025) in Frontiers in Psychiatry, analyzing 17 studies and 879 participants, found an SMD of −1.01 for depression and −0.62 for anxiety in horticultural therapy contexts, while emphasizing methodological limitations.
A more recent RCT by Joubert (2024) in Scientific Reports, with 211 psychiatric patients, demonstrated a reduction of −1.48 points in the HADS-Anxiety score after 4 weeks of gardening interventions. These results are promising but do not equate to a cure.
And specifically on terrariums?
Specific scientific research on terrarium-making is still limited. The only peer-reviewed study that focuses directly on this activity is by Gavron and Shemesh (2022/2024), who explored the concept of "Expressive Terrarium" in the Journal of Art Therapy, with preliminary results suggesting expressive and well-being benefits.
It is important to note that, while the evidence on indoor gardening and horticultural therapy is solid, we cannot automatically extend all benefits to terrarium-making without dedicated studies. The observed effects are inferred from broader literature, but the specificity of the activity (closed ecosystem, precision care) may have peculiarities not yet fully investigated.
Key Points
- Psychological benefits — Terrarium-making can reduce perceived stress and state anxiety, promoting mindfulness and psychophysical well-being.
- Scientific evidence — Studies on indoor gardening and horticultural therapy support positive effects on mood and concentration, with specific research on terrariums still in the preliminary phase.
- Inclusive activity — It can be a meaningful activity for people with Parkinson's, anxiety, ADHD, dementia, or for those seeking a break from digital life, always with due precautions.
- Not a therapy — It is crucial to distinguish terrarium-making from clinical treatment; it does not replace professional medical or psychological care.
- Mindful practice — The act of assembling and caring for a terrarium fosters fine motor skills, concentration, and a sense of accomplishment, improving attention.

Who can benefit: stories and contexts
Terrarium-making, while not a therapy, can be a valuable activity for various categories of people, offering an opportunity for engagement, calm, and connection with greenery, adapting to different contexts and needs.
Its characteristics make it an interesting option for those seeking a manual and meaningful activity.
People living with Parkinson's or other neurological conditions
Like the friend who shared his experience with me, many people with Parkinson's find benefit in precise manual activities. The systematic review by Foster, Bedekar, and Tickle-Degnen (2014) in the American Journal of Occupational Therapy highlighted how task-specific activities in occupational therapy can improve motor functions and quality of life.
Although terrarium-making does not "improve fine motor skills" or "reduce tremors" in a clinical sense, engaging in a pleasant, focused activity can distract from symptoms and promote a sense of control. Dirkx, Helmich, and Bloem (2017) in CNS Neuroscience & Therapeutics showed how cognitive stress can increase resting tremor; conversely, calm environments and pleasant activities are consistent with a more serene experience.
For many people with Parkinson's, meaningful manual activities can be engaging and enjoyable. This does not mean that a terrarium is therapy: it means it is a human activity that some find sustainable and gratifying. If you are considering a kit for someone with reduced motor skills, it is advisable to opt for open formats or kits with larger elements, such as our Lamparium Kit, and consult your occupational therapist to assess suitability.
People living with anxiety, chronic stress, burnout
For those living with anxiety, work-related stress, or burnout, terrarium-making offers a tangible break. The manual activity and concentration required can act as a form of practical mindfulness, anchoring the mind to the present and reducing rumination. Studies by Lu (2023) and Joubert (2024) previously cited support the idea that indoor gardening can reduce state anxiety and improve mood.
The ritual of caring for a small ecosystem, observing plant growth, and maintaining balance can create a sense of calm and control. This "flow state," where one is completely immersed in the activity, is a powerful antidote to stress. For those working in high-pressure environments, integrating natural elements, such as a Rectangular Moss and Stabilized Lichen Frame or a terrarium, can contribute to a more relaxing environment, as suggested by studies by Bringslimark, Hartig, and Patil (2007) on office plants.
Children and teenagers (including those with ADHD or attentional dysregulation)
Contact with natural elements and manual activities is often enjoyable for children. Building a terrarium can be a hands-on activity that stimulates curiosity, responsibility, and patience. Studies such as that by Kuo and Taylor (2004) in the American Journal of Public Health have suggested that exposure to nature can improve concentration in children with ADHD, although Hood and Baumann (2024) and Gordon and Canu (2005) have highlighted the need for further research and caution in interpretation.
This doesn't mean that a terrarium "cures" ADHD: it is not a treatment. It means it can be a meaningful and quiet activity to do together, with adult supervision for tools and to ensure safety with materials like activated charcoal. Our "Giulia's World" kit is designed specifically for children, with easy-to-handle components and clear instructions for a fun and educational experience.
Elderly people and care settings
In nursing homes and assisted living facilities, structured horticultural therapy programs show promising results on agitation and mood. A meta-analysis by Lu, Lan, and Hsieh (2019) in the American Journal of Alzheimer's Disease & Other Dementias, involving 552 people with dementia, found a reduction in agitation with an SMD of −0.59. Murroni, Cavalli, and Basso (2021) also highlighted similar benefits.
At home, a terrarium kit can be an activity shared with a family member, with supervision: it does not replace professional interventions. The activity of creating and caring for a terrarium offers a sense of purposeful activity, stimulating memory, motor skills, and socialization if done in a group. It is a way to keep the mind active and enjoy the beauty of nature, even in limited spaces.
Adults seeking a break from digital devices
Even for healthy adults, a terrarium offers a concrete and relaxing alternative to digital overload. It is an activity that encourages disengagement from screens, stimulating creativity and mindfulness. The time spent composing one's mini-green world is an investment in one's well-being, a moment of "slow living" that contrasts the hectic pace of modern life.
It's not just a pastime, but a practice that can improve quality of life by reducing cortisol levels (the stress hormone) and improving heart rate variability (HRV), indicators of a more balanced autonomic nervous system.
Why a terrarium and not another manual activity?
In a world rich in manual hobbies, the terrarium stands out for its ability to combine creative aspects with the care of a living ecosystem, offering a unique and deeply gratifying experience.
It is not just an object, but a continuously evolving process that connects us to nature.
The unique combination: live plants + aesthetic composition + ongoing care
Unlike many other manual activities that conclude once the project is finished, a terrarium is a living work that requires continuous care and observation. This prolonged interaction with plants fosters a special bond, a sense of responsibility and connection with nature.
The aesthetic composition, the choice of plants and decorative elements, stimulates creativity and a sense of beauty, transforming the process into a personal artistic expression. It is a micro-landscape that evolves, always offering new nuances to admire.
Difference from puzzles, models, knitting (which are also very valuable)
While puzzles, models, or knitting are excellent manual activities for concentration and relaxation, the terrarium adds a unique dimension: the "life factor." It's not just about assembling pieces or following a pattern, but about creating a sustainable environment for living beings.
This difference is crucial for those seeking an activity that goes beyond a simple pastime, offering an opportunity to nurture and observe growth, an experience that can be deeply therapeutic and regenerating.
The "life factor": taking care of something that grows
The true heart of terrarium-making is taking care of something that grows. Observing small plants thrive, adjusting humidity, cleaning the glass, are all gestures that reinforce a sense of competence and personal effectiveness.
This "life factor" can be particularly significant for those who feel overwhelmed or are seeking a sense of purpose, offering a daily reminder of the resilience and beauty of nature.
From our nursery experience
In our workshop, over the years, we have noticed how terrarium kits have become an increasingly popular gift for special occasions, often for people seeking a moment of calm. Our third-generation nurserymen tell us about customers who return to share the joy of seeing their small ecosystem thrive, a sign that caring for these small green oases brings a tangible benefit, a moment of serenity and pride, even for those who have never considered themselves to have a "green thumb."
How to get started: choosing the first terrarium based on you (or the recipient)
Choosing your first terrarium is an important step to ensure a rewarding experience. The decision depends on your needs, available time, and, if it's a gift, the profile of the person who will receive it.
Step-by-Step Guide
Our kits are designed for different abilities and preferences, ensuring an ideal starting point.
Closed vs. open vs. lamparium with light
The choice between a closed, open terrarium, or a lamparium with integrated light largely depends on the environment and desired maintenance. Closed terrariums create an autonomous microclimate with minimal intervention required, ideal for those seeking a self-sustaining ecosystem.
Open terrariums require a bit more attention for irrigation, but are perfect for plants that prefer dry air or for those who want to interact more often with their plants. Lampariums, with integrated LED light, offer an aesthetic and functional solution, ensuring proper lighting and creating a luminous focal point in any environment, even with little natural light.
How much time to dedicate (research says: 10–30 minutes are enough to feel acute effects on perceived stress in crossover studies; for sustained benefit, frequency ≥2/week, as suggested by Wang, Qian, Yu 2024)
It's not necessary to dedicate hours every day to feel the benefits of a terrarium. Research suggests that even just 10-30 minutes of interaction with plants can have acute effects on reducing perceived stress, as demonstrated in crossover studies.
For sustained benefit over time, a frequency of at least twice a week, as indicated by recent studies (Wang, Qian, Yu 2024), may be sufficient. The important thing is the quality of the time spent, presence, and awareness, not the quantity.

Building it as a practice: the 7 steps that truly help
Building a terrarium is not just a manual activity, but can become a true mindfulness practice. Each step, if performed with awareness, contributes to creating a relaxing and meaningful experience, a moment of connection with nature.
Following these 7 steps will help you maximize the benefits for your mind.
7 steps of mindful terrarium building:
- Prepare your space (good light, no screens, 30 minutes for yourself) — Find a quiet corner with good indirect natural light. Put away your phone, turn off notifications. Dedicate at least 30 uninterrupted minutes to yourself and your terrarium. This is your moment.
- Touch the materials before assembling them (sensory reconnection) — Feel the texture of the stones, the dampness of the moss, the softness of the soil. This tactile exploration physically connects you with natural elements, stimulating your senses and rooting you in the present.
- Drainage layer: listen to the sound of the clay — Pour the expanded clay or pebbles onto the bottom of the jar. Listen to the sound they make as they fall. This simple, repetitive gesture can be surprisingly meditative, a rhythm that calms the mind.
- Activated charcoal: small gesture, maximum attention — Gently sprinkle the activated charcoal. It's a gesture that requires precision and attention, a small ritual that emphasizes the importance of each element in your ecosystem.
- Substrate: shape with your hands, feel the moisture — Add the potting mix. Feel it between your fingers, shape the surface with your hands, feel its moisture. This direct contact with the earth is a profound sensory experience, a call back to our biophilic roots.
- Plant arrangement: choose calmly, it's not a chore — Carefully place the plants, thinking about their growth and visual harmony. There's no rush, it's not a race. Each plant has its place, and you are the architect of this small world.
- Final misting: your mini-ecosystem's first "breath" — Conclude with a light misting of water. Observe the droplets settling on the leaves, like your terrarium's first breath. It's a gesture of care and welcome to this new life.
What to do if you get distracted (and why that's perfectly fine)
It's natural for the mind to wander, even during a meditative activity. If you notice you've been distracted, don't judge yourself. Simply bring your attention back to the materials, sounds, and sensations. This act of "returning" to the present moment is the true essence of mindfulness.
Every time you get distracted and bring yourself back to the activity, you are training your attention and your ability to be present, a valuable benefit for the mind.
Daily care as ritual
Caring for a terrarium doesn't end with its construction. Daily or weekly maintenance – checking humidity, lightly cleaning the glass, observing the plants – can become a small ritual, a moment of pause and reconnection. This ritual provides structure and a sense of continuity, helping to maintain psychological benefits in the long term.
It's a constant reminder of nature's beauty and your ability to care for it.
Safe materials, non-toxic plants, supervision with children
To ensure a safe and enjoyable experience, all our terrarium kits, including those for children like "Giulia's World", contain non-toxic plants and certified materials. However, adult supervision is always recommended when children use tools or handle small components, to avoid accidental ingestion or injury. Safety is our priority, for worry-free well-being.
What a terrarium is NOT (and why it's important to say so)
While the benefits of terrarium-making are evident and supported by scientific evidence on indoor gardening, it's essential to be clear about what this activity is not. This clarity is a sign of respect and honesty towards those seeking genuine support for their health.
A terrarium is a wellness activity, not a medical solution.
- It is not clinical therapy. Horticultural therapy is a professional, structured intervention conducted by qualified therapists for specific therapeutic goals. Home terrarium-making, while inspired by similar principles, does not fall into this category.
- It does not replace psychotherapy, medication, occupational therapy, or physical therapy. For medical or psychological conditions, it is essential to rely on the advice and care of healthcare professionals. A terrarium can be a complement, but never a substitute.
- It does not cure Parkinson's, anxiety, depression, ADHD, dementia, or Alzheimer's. No manual activity, however beneficial, can cure complex pathologies. To claim otherwise would be dishonest and misleading.
- It is not suitable for everyone at all times. There are situations where a terrarium might not be advisable, such as during acute phases of illness, for people with severe allergies to plants or substrates, or for very young children without adequate supervision, due to the risk of ingesting small components.
Saying this does not detract from the value of the terrarium. It places it in its rightful place: an activity of well-being, creativity, and care, inspired by horticultural therapy practices but distinct from them. It is a way to take care of yourself and nature, with awareness and without false expectations.
Frequently Asked Questions
Does making a terrarium really help reduce anxiety?
Yes, for many people, the activity of building and caring for a terrarium can help reduce state anxiety, which is transient anxiety related to specific situations. Studies on indoor gardening, such as the meta-analysis by Lu et al. (2023) and the RCT by Joubert (2024), have shown a significant decrease in psychological indicators of stress and anxiety. The focused attention and "soft fascination" promoted by terrarium-making can distract the mind from worries, fostering a sense of calm and presence.
Can building a terrarium help a person with Parkinson's?
A terrarium is not a therapy for Parkinson's, but the manual and precise activity required can be engaging and rewarding. Foster et al.'s (2014) review highlighted the benefits of task-specific activities in occupational therapy. For some people, focusing on delicate tasks like positioning small plants can offer a moment of calm and a sense of control, reducing stress that can influence motor symptoms. It is essential to consult an occupational therapist to assess suitability and choose appropriate kits.
How much time should one dedicate to feel the benefits?
Research suggests that not much time is needed. Even short sessions, 10-30 minutes, can have acute effects on perceived stress reduction. For more lasting and sustained benefits, studies like Wang, Qian, Yu (2024) indicate that a frequency of at least twice a week can be effective. The important thing is the quality of attention and presence during the activity, transforming it into a small wellness ritual.
Can I give a terrarium kit as a gift to a friend going through a difficult time?
Yes, a terrarium kit can be a meaningful gift for a friend going through a difficult time, as long as it's clear that it's not a therapeutic solution. It offers a manual activity, a positive focus, and a symbol of new life. It's a gesture of care that invites mindfulness and reconnection with nature. Choose a kit suitable for their experience level and, if necessary, suggest they discuss it with a professional.
Is it also suitable for children with attention difficulties?
Terrarium-making can be an engaging activity for children, including those with attention difficulties, as it stimulates concentration and fine motor skills. Contact with nature and manual activities are often enjoyable and can promote "soft fascination". It is not a treatment for ADHD, but it can be a way to practice attention in a playful and creative context, always with adult supervision to ensure safety and necessary support.
Is it suitable for elderly people or those with dementia at home?
For elderly people or those with dementia, a terrarium can offer a meaningful and stimulating activity, especially if done with a family member or caregiver. Studies on horticultural therapy in assisted contexts, such as the meta-analysis by Lu et al. (2019), have shown a reduction in agitation and an improvement in mood. It is important to choose kits with easy-to-handle components and ensure adequate supervision, adapting the activity to individual capabilities. It does not replace professional interventions.
What is the difference between horticultural therapy and making a terrarium at home?
Horticultural therapy is a structured clinical intervention, led by a qualified therapist, with specific and measurable therapeutic goals, often in rehabilitation settings. Making a terrarium at home, on the other hand, is a personal wellness and recreational activity. While sharing some principles (contact with nature, manual activity), home terrarium-making does not have diagnostic or therapeutic purposes and does not replace a professional clinical pathway.
Do you need a "green thumb" to start?
Absolutely not. Terrarium kits, especially beginner ones like the Nadia Kit, are designed to be easy to assemble and maintain, even for those with no plant experience. Detailed instructions and the choice of hardy plants make the experience accessible to everyone. The goal is to enjoy the process and the benefits that come with it, not to demonstrate advanced botanical skills. It's a great way to slowly develop your "green thumb."
What if I have anxiety but also allergies to pollen or potting soil?
If you suffer from allergies, it is essential to choose carefully. Many closed terrariums reduce pollen exposure. For potting soil, you can opt for inert substrates or hydroponics, or wear gloves and a mask during assembly. It is advisable to consult your allergist before starting. Our kits use selected plants, but individual sensitivity varies. Safety is a priority to ensure a risk-free wellness experience.
Can terrariums be used in schools or nursing homes as workshops?
Yes, terrarium-making is very well suited for educational or recreational workshops in schools and nursing homes, provided the activity is adapted to the age and abilities of the participants and conducted with supervision. It offers a practical opportunity to teach ecological concepts, stimulate creativity, and foster socialization. In therapeutic contexts, it can be integrated into occupational therapy programs with specific goals, always under the guidance of qualified professionals.
