Drought-tolerant Plants

Drought-tolerant plants can manage longer dry periods once their roots are established. They still need water after planting, and many grow better with occasional deep watering during extended dry weather. Soil depth, mulch and root competition can matter as much as rainfall. 38 plants in the library.

Before You Choose

Give new plants time to build roots beyond the original nursery pot. Water deeply through establishment, then gradually increase the interval between waterings if the species and season allow. Frequent shallow watering keeps most roots near the surface and makes plants more dependent on the next drink.

Mulch is one of the simplest ways to stretch soil moisture. It shades the surface, reduces evaporation and limits competition from weeds. Leave space around trunks and crowns so the mulch does not hold constant moisture against the plant itself.

Soil changes the picture. Deep loam or clay can store water for much longer than shallow sand or rocky ground. A plant that sails through a dry spell in deep soil may need more help in a raised bed, pot or exposed slope.

Also check heat and wind. Hot dry wind can remove moisture quickly even from drought-adapted plants. Shelter, planting density and afternoon shade may reduce stress in very exposed gardens. Use this list as a starting point, then compare climate, soil, mature size and light on each profile.

Plant density also changes water demand. Closely planted shrubs and trees may shade the soil, but their roots still compete for the same stored moisture. In a dry garden, mature spacing gives each plant more access to the root zone you are watering. Group plants with similar water needs so you can irrigate deeply where it helps without watering the whole garden unnecessarily.
