So imagine you have a little garden in your home. You have some plants, flowers, maybe some vegetables, and you take care of them by watering them and giving them sunlight.
Now, imagine if you were feeling sad or angry or even just a bit stressed. You could go outside and tend to your garden, which would make you feel better. This is kind of like how horticultural therapy works.
Horticultural therapy is a type of therapy that uses gardening and plants to help people feel better. It can help people who are feeling sad or anxious or stressed. Sometimes it's used to help people who have illnesses, too.
The therapy can include growing plants or even just spending time surrounded by them. Sometimes people might do some special activities like planting seeds or flowers or making a birdhouse.
It's a little bit like how playing with toys helps you feel better when you're upset. Except with horticultural therapy, you're playing with plants and gardens instead!
