Watering & Plant care Tips for Summer's Sizzle

by Donna DiFrancesco,
Master Gardener, Water Conservation Specialist City of Mesa

Don't let our current spring-like weather fool you. Summer is just around the corner and the long, hot, dry conditions ahead can tax the endurance of many plants. For plant success this summer season, follow these tips:

ADJUST WATERING SCHEDULES
Water needs will increase as the temperature rises. Landscape watering guidelines are available from you city water conservation office. They are printed onto a handy, plastic card that can be placed right inside your irrigation controller box. Call your water conservation office for a free copy.

CHECK IRRIGATION SYSTEMS
Replace clogged drip emitters and repair leaks. Increase emitter numbers and adjust emitter placement on trees. For sprinklers, place cups or cans out in your lawn, turn your system on, and check for uneven coverage to determine problem areas.

MULCH PLANT ROOTS
Replenish organic mulches around your plants each year to improve soil, reduce moisture loss, and keep roots cool during the summer months. Keep mulch away from plant trunk or main stem and cover the mulch with granite if you prefer.

REMOVE WEEDS
Winter weeds can compete with landscape plants for water. Remove the weeds by hand or check with your local nursery for safe weed sprays.

FERTILIZE NON-NATIVE PLANTS
Follow product label recommendations to fertilize established non-native plants. Native plants usually do not require fertilizers and generally grow better without them.

PRUNE FROST-DAMAGED PLANTS
If plants have been damaged by the cold, wait until new growth emerges before you prune. Prune other plants only when necessary. Low tree limbs or branches keep plants shaded and cooler in summer.

REPLANT LOST PLANTS
If plants have died or are not performing well, plant new ones before the summer heat sets in. Be sure to select native or well-adapted plants to ensure future success.
