Do you recall times in the garden when, after weeding a row of flowers, you had more energy? Or after a walk outdoors, you felt more peaceful? If so, you experienced the therapeutic benefits of horticulture, and you are one of many who retreat to the garden to relax, renew energy, create a sense of place, and restore self-esteem.
Therapeutic Horticulture is the purposeful use of plants and plant-related activities to promote health and wellness for an individual or group. A garden benefits you on many levels. One seemingly magical effect of gardening is stress relief. Emotional benefits of gardening may derive in part from the sense of the natural rhythm of life that plants and gardens impart. It can divert thoughts about yourself and your situation. In the garden, you can create and control your environment. This control is empowering. Gardening stimulates all of the senses, giving great pleasure and satisfaction. You can design a garden to challenge your strength and balance, or promote eye-hand coordination, range-of-motion, and endurance to just about any degree you want. Cognitively, gardening benefits the mind. Designing a garden and learning about plants and specific gardening techniques can be done in a number of simple or complex ways. And with books or classes, you can learn new things year-round.
Besides these benefits, gardening brings you together with other people. Human bonds created between gardeners have the potential to transcend social barriers. Gardens invite socialization. Bringing plants and people together promotes cooperation. The garden neither judges nor discriminates. It's a safe environment where people of all ages, backgrounds, and abilities can come together, connected by the simple fact that we all rely on the earth to survive.
Generations together in the garden.
What is an accessible garden?
According to the Merriam Webster dictionary "accessible" means the "capacity to enter or approach, to get at or gain access to something." When thoughtlfully planned, an accessible garden eliminates physical and attitudinal barriers to gardening, creating an area where people of all ages and abilities can garden. All you need are a few simple adaptations to the area, methods, and equipment.
Raised beds are large bottomless boxes that contain soil and permit drainage below. Since they can be expensive to build, raised beds should be used in areas of the garden that require the most frequent attention. For instance, it makes more sense to build a raised bed for vegetables requiring intensive weeding than for a low-maintenance border of shrubs. Build raised beds as large as possible, making sure that you can reach all areas of the bed. The increase in size adds minimal cost to the bed, while adding valuable garden area. Bed width should be a maximum of 5 feet if it is accessible from all sides, or 2.5 feet if used from only one side. If using extended tools, you can add inches to the bed. Seating ledges should be from 8 to 18 inches wide. Use the thinnest construction materials possible without compromising stability, to increase the area available for the gardener. Height of the sides can vary from 18 inches for a child, to 24 inches for someone seated in a chair next to the bed, to 30 inches or higher for the standing gardener who has difficulty bending downward.
Boxes and pots of various sizes provide successful ways to grow vegetables and flowers. Choose a pot that will allow for healthy root development. For instance, bush-type peas, beans, cucumbers, kale, broccoli, and lettuce do well in a box that is 1-by-4 feet and 8 inches deep. For some other plants, such as beets, carrots, onions, lettuce, leeks, turnips, kohlrabi, corn, and zucchini, a box that is 2-by-3 feet and 8 inches deep is more suitable. For herbs and flowering plants and vines, find out whether the plant is deep- or shallow-rooted to determine the proper container size. The more shallow the container, the faster it will dry out.
Hanging baskets can create planting space where none exists. Or, combined with a container garden, they can give you a double-decker growing area. To make watering and viewing easy, buy a ratchet pulley. Or make your own pulley, using steel hooks or rings clamped or mounted to railings or walls. A long metal pole with a curving top hook can be anchored in the ground for a freestanding hanging plant mount. Baskets can be hung high, or if you have limited mobility, hung low enough to see and enjoy their beauty.
Table planters are shallow soil-filled trays supported on legs. About 27 inches of knee clearance is needed to allow chairs to fit underneath. The soil container should be at least 8 to 10 inches deep, making the entire structure about 35 to 37 inches high. The top of the planter should be no higher than your rib cage. Width of the box is the same as that of the raised bed, already described.
Deep boxes, barrels, and tubs can be used to create miniature raised beds for flowers, vegetables, and herbs. Perennials, trees, and shrubs are not recommended for these types of containers because plants cannot survive in them when the temperature is freezing or below freezing. Use these containers for your annual plants only.
|Plants to use in accessible garden containers
There are many new varieties of plants that are appropriate for the accessible garden container. Look for plants listed as Īcompactā (e.g. "Pixie" tomatoes). Compact plants will typically be more suitable for container growing smaller and easier to reach if you use a wheelchair. Also look for tall plants or vines that reach a certain height, thus making them good choices for growing on poles, stakes, and trellises. Choose flowers not only according to their light requirements and shape, but also by their colors, textures, and fragrances.
|Asphalt||Absorbs and radiates heat. Hot in summer, but snow melts off sooner.|
|Wood decking||Slippery when wet.|
|Brick||Expensive and must be installed properly.|
|Decomposed granite||Readily available. Good for persons in wheelchairs but not for those on crutches.|
|Screenings||Large and small limestone pieces (similar to decomposed granite).|
|Concrete||Expensive; glare can be a problem for elders and people with visual impairments.|
|Woodchips and turf||Use only for persons without ambulatory equipment.|
