GROWING GUIDE: Drought Tolerant Plants
In order for a plant to withstand long periods of dry weather, it is necessary to dig in a lot of organic amendments such as compost, aged manure or peat moss. These materials will
help hold moisture in the soil. Start your plants off with deep irrigation the first season and they will cbe more drought tolerant after the root system is established.
