Taking Care of Drought-Tolerant Trees

If you live in an arid or semi-arid climate, you know how important it is to choose drought-tolerant trees for your landscape. Here are some tips that will help you take care of drought-tolerant trees –

  • Water the tree at least once any day for 1-2 weeks after planting it. Then do it once every 2 to 3 days during weeks 3 to 12. And depending on the species, water the tree once each week during the 13th week till it’s 2-3 years old. After the first two weeks, make sure to let your soil dry out first before you water the tree in order to help it grow deep roots. 
  • New trees usually require 10 to around 20 gallons of fresh water each week. 
  • It’s better if you plant your shrubs and trees around your lawn or property in complementary groups, so they will work like anchor points for hardscape features, pathways, and smaller plants. You can also complement the trees with perennials or shrubs that are drought-tolerant. 
  • Make sure to increase the watering area while the tree grows, as the roots of the tree expand outward during the growth.
  • You can try preserving the soil’s moisture and providing proper nutrients for the roots by spreading wood layer mulch of 2-3 inches in a ring around the tree’s base. To prevent internal rot, try keeping the mulch 3-6 inches away.
  • It’s better to use soaker hoses instead of a sprinkler while watering the new trees, as the hoses are pretty much efficient.
