Drought Tolerant Groundcovers for Dry Climates
Low-water groundcovers are replacing Parts of Lawns in the West
May 21, 2009
With the California drought in full throttle many homeowners are seeking plants that can survive the hot, dry summer days. Some are choosing to remove their lawns (which should be done in the fall so they’re established by next summer) while others are removing water thirsty plants or small parts of a lawn and replacing it with low-water groundcovers.
A few preliminary notes:
- Once you remove a section of lawn, make sure to amend the soil. Before you plant anything blend in a 2-4" layer of compost. If your soil is compacted or you're new to gardening, dig the compost down a few inches. Then plant. If you've added compost to your soil once or twice a year, your soil should be in good condition so you can just add a thin layer of compost to the top. The microorganisms in the organic matter will take the nutrients down to the roots for you. They are 'your people!' After planting, add a 2-3 inch layer of mulch (wood chips, leaves, straw, shredded bark) to keep plants cool and shade weed seeds.
- There is no such thing as a drought tolerant plant the first season! All plants need a bit of coddling when they are young and vulnerable. You’ll need to water regularly during the first summer-usually once every 4-7 days. From the 2nd year on you can taper off on watering.
- Always water deeply to encourage deep rooting. Shallow frequent waterings are a waste of water and time.
