To spray succulents, you will need to purchase insecticide soap. Mix a tablespoon of the soap with cool water in a spray bottle. To apply fine water spray to the succulents without damaging their roots, you can use a turkey baster. While most gardeners use tap water, some gardeners prefer to use rainwater for its healing properties. You can make an "Echeveria Garden" with different genuses or a combination of completely different plants. It is best to use small pots, shells, and stones with natural depressions and hollows. It can be difficult to see if this happens when you're at the store.
