Just because you have a small space doesn't mean that you don't have room for a great sensory garden. With some careful planning, you can make the most of the room you have.
One of the important elements of any garden is a central open shape. There is often not enough room or no desire for turf to be used for that open shape. Other materials, such as hardscape, can be used instead.
Hardscapes, such as pavers, concrete, stone, etc., can make a beautiful and practical central open shape. You may choose to make the area circular (although pavers would be difficult in such a situation), or you can make the shape rectangular for more of a formal garden feel.
Some recommendations for making a patio a great sensory garden include the following:
Don't be afraid to be daring with any designs you plan on using for the central open shape. Your space is limited and you want to make the most out of it.
If a storage shed is required, screen it from view with thick plants for vines
Find space for a small water feature. Keep it away from where you would eat food but close enough to enjoy. Try raising it to give it a more prominent place in the garden.
Be flexible with the seating. Have your seating on wheels where it can be moved around as needed. You may be creative with the seating. Perhaps they can serve as both seats and storage when you open the top.
Your plant choices should provide foliage year-round, when possible. Your goal is shape and texture, so don't focus on color. Rather, incorporate plants that are rich and green and require little maintenance.
Even a small outdoor space can become an immersive healing sensory garden. You can make the most of the space to feel comfortable without feeling overcrowded.
