July is Smart Irrigation Month, which calls to mind the smart use of water, a precious resource that a lot of gardeners take for granted. Even though rainfall may be plentiful and there are no water restrictions in your community, it’s still smart to be smart about watering tasks.

Irrigation Tips:

  • Direct water to the root zone rather than on plants. Avoid watering during the heat of the day, when evaporation is high.
  • Overhead sprinklers are less efficient than those that distribute water close to the soil.
  • If your community has water restrictions or you’d like to conserve the resource, prioritize your watering needs. Usually food gardens and containers come first, followed by annuals in the ground, perennial beds, shrubs and trees. A healthy lawn can usually go a month to six weeks without water.
  • Make sure your irrigation system is set for the different zones in the landscape. Lawns may be irrigated two or three times a week, while trees and shrubs only need to be watered deeply every week or so.
  • Keep plant growing well with applications of Natural Start by GreenView All Purpose Plant Food or Natural Start by GreenView Tomato, Vegetable, & Herb Food, according to label directions.

Consider selecting plants that can take the heat but continue to look good in the garden. These heat-loving, drought-tolerant plants can take the heat even with little or no rainfall or supplemental watering.

Perennials

  • Lavender –fragrant and delicious. Leave upright in winter. Cut back to new growth in spring when leaves start to form. Winter hardy to USDA Zone 5.

  • Sedum – especially the late summer blooming Autumn Joy with succulent-like leaves. Monarchs and native bees enjoy this plant’s flowers.
  • Threadleaf Tickseed/Coreopsis –this Eastern U.S. native’s fine, grass-like foliage adds interesting texture in a flowerbed. Popular varieties include ‘Moonbeam’ and ‘Zagrebe’.
