Creating a therapeutic sensory garden is a thoughtful and intentional process that aims to enhance the well-being of individuals, particularly those with dementia, autism, PTSD, ADHD, sensory processing disorder, blindness, and deafness. These gardens are designed to provide a calming and stimulating environment that engages multiple senses, promoting emotional and cognitive benefits. In this article, we will delve into the key steps and considerations for designing a therapeutic sensory garden, ensuring it meets the unique needs of its users.

Understanding Therapeutic Sensory Gardens

Therapeutic sensory gardens are not just aesthetically pleasing spaces; they are meticulously crafted environments that cater to the diverse needs of individuals. These gardens are designed to stimulate the senses—sight, sound, touch, taste, and smell—while also providing a safe and accessible space for interaction. The primary goal is to create an environment that promotes relaxation, reduces anxiety, and enhances overall well-being.

Historical Context

The concept of therapeutic gardens has its roots in historical relaxation gardens and health sites. For instance, in Latvia, there has been a long-standing tradition of developing sensory and healing gardens near medical facilities. These gardens were designed to provide patients with a connection to nature, which is essential for their mental and physical health.

Benefits of Therapeutic Sensory Gardens

Research has shown that therapeutic sensory gardens offer numerous benefits for individuals with various disabilities. For people with dementia, these gardens can improve behavioral, cognitive, and mood aspects. The presence of water features, specific plant types, and interactive activities can significantly enhance the therapeutic effect. For seniors in nursing homes or senior housing, therapeutic gardens provide a soothing experience that brings them closer to nature and beauty.

Planning a Therapeutic Sensory Garden

Before embarking on the design process, it is crucial to understand who the garden is for and how it will be used. This involves gathering information about potential users, their interests, abilities, and functional needs. Involving users in the planning process can help avoid designs based on assumptions rather than actual needs.

Identifying User Needs

1. Who is the Garden For?

   • Will it be used by the same people or different groups?
   • What is the range of interests and abilities?
   • What are the functional needs—shade, shelter, seating?

2. How Will the Garden Be Used?

   • When will people want to use the outdoor space? Think seasonally, weekly, and time of day.
   • Are there times when it won't be used? Consider holidays or other periods of inactivity.
   • How many people are likely to use the garden at any one time? Is there a need for individual use as well as bigger groups?

3. Staff Needs

   • Can the space provide opportunities for staff to take a break?
   • Is there a need for somewhere where people can smoke?

Involving Users in the Process

Bringing people together to make plans and share ideas, concerns, and experiences is essential. This collaborative approach ensures that the design meets the needs of those who will use it. It also helps get people on board with the project, ensuring a higher likelihood of success.

Design Considerations

Sensory Pathways

Sensory pathways are a crucial element in therapeutic sensory gardens. These pathways can include various types of surfaces such as sand, flagstone, woodchips, or smooth stepping stones. The choice of surface should be based on the needs of the users. For example, smooth stepping stones can be beneficial for individuals with mobility issues.

Plant Selection

When choosing plants for a therapeutic sensory garden, several factors must be considered:

1. Non-Toxicity

   • Plants should be non-toxic and non-allergenic to ensure safety for users.
   • Avoid plants with thorns or other hazardous features that could cause injury.

2. Sensory Stimulation

   • Select plants that offer a variety of sensory experiences—visual, auditory, tactile, olfactory, and gustatory.
   • Incorporate plants with different textures (e.g., soft flowers, fuzzy leaves), colors (e.g., contrasting elements of color), and scents (e.g., fragrant flowers).

3. Seasonal Interest

   • Choose plants that provide seasonal interest to keep the garden engaging throughout the year.
   • Consider plants with varying blooming times and foliage shapes and sizes.

4. Accessibility

   • Ensure that plants are accessible for users with mobility issues by placing them at waist height or lower.
   • Use raised beds or containers if necessary to make plants more accessible.

Hardscaping Elements

Hardscaping elements are essential components of a therapeutic sensory garden. These include seating areas, standing areas, and climbing structures with different textures for users to see and touch. For example, grouping rough-textured tree stumps for seating can provide a tactile experience.

Safety Features

Safety is paramount in designing a therapeutic sensory garden. Ensure that the garden is free from hazards such as sharp objects or toxic substances. The garden should also be well-lit to prevent accidents and enhance visibility for users with visual impairments.

Designing for Specific Needs

For Seniors and Individuals with Dementia

1. Clear Framework

   • The framework of the garden needs to be clear, predictable, intuitive, safe, and secure with a perceived sense of balance between freedom and enclosure.
   • A quiet perceptual sensory environment is needed to reduce anxiety and enhance clarity.

2. Simplified Stimuli

   • The garden must be a stronger and simpler stimulus than would be designed for younger visitors.
   • Avoid overstimulation by balancing energizing colors with restful ones.

3. Visual Considerations

   • By age 80-90, visual acuity is significantly reduced; thus, visual elements should be clear and easily distinguishable.
   • Use large-scale features like large flowers or plants with bold colors to compensate for reduced vision.

4. Auditory Considerations

   • Audible insensitivity can mean that users cannot hear sounds like unsteady walking or low-level talking.
   • Incorporate sound-enhancing elements like dripping water or wind chimes to create a more engaging auditory experience.

5. Tactile Considerations

   • Tactile sensitivity is also reduced with age; thus, tactile elements should be prominent but not overwhelming.
   • Incorporate smooth stones, rough bark, and other textured elements for users to explore.

6. Olfactory Considerations

   • Olfactory sensitivity is also reduced with age; thus, fragrant plants should be strategically placed.
   • Use essential oils or scented candles in areas where users can easily access them.

7. Gustatory Considerations

   • While taste is not typically a primary focus in sensory gardens, ensuring that all elements are non-toxic is crucial.
   • Avoid using plants that could potentially cause harm if ingested.

Creating a Therapeutic Sensory Garden

Step-by-Step Guide

1. Define the Purpose

   • Clearly define the purpose of your therapeutic sensory garden—whether it is for relaxation, stimulation, or both.
   • Identify who will use the garden and what their specific needs are.

2. Conduct User Research

   • Gather information about potential users through surveys, interviews, or focus groups.
   • Understand their interests, abilities, and functional needs.

Case Studies

Indoor Therapeutic Garden

One example of an indoor therapeutic garden was conducted at a care home in the city center. The garden included a large, purpose-built area covering 300 square meters with non-toxic plants that promoted olfactory, visual, and tactile stimuli. The trail was endless and encouraged movement and contact with plants. The entrance gave direct access to the trail built with smooth, non-slip material. Inside the garden there were two areas for sitting and socializing, as well as a fountain with running water. The garden walls had large glass windows covered with a safety film affording direct views from inside. Temperature and humidity were kept constant.

Outdoor Sensory Garden

Another example is an outdoor sensory garden placed in the dining room on the first floor. Although the time of year was not stated, participants were encouraged by researchers to interact with all plants. They were asked what the plants reminded them of involving all senses—taste, touch, scent. Plants included Coriandrum sativum (coriander), Lactuca sativa “Simpson Elite” (lettuce), Hosta “Patriot” (hosta), Rosemary (rosmary), Brassica juncea “Red Giant” (mustard greens), Chrysanthemum (chrysanthemum), Dracaena (dracaena).
