FREE Landscape Maintenance Tips



• Check to make sure the mulch is still covering plants that are exposed to the south and southwest.
• Comprehensive pruning should be done on all trees and shrubs (except maples) for correction, height, damage, or shape.
• Deep water trees, shrubs, and roses as needed.


• Use dormant oils to control scale or aspen black spot.
• Thin old, overgrown deciduous shrubs before they start to bud out or bloom.
• Gently brush the snow off trees and shrubs.


• If you didn’t rake leaves or remove old fruit from fruit and deciduous trees in the fall, do so now.
• Check evergreen for browning and deciduous trees for buds that have died. Prune, don’t shear deciduous trees.
• Deep water trees and shrubs as needed.


• Cut back perennials (except evergreen perennials-plants that stay green all year) from last year. With a sharp pair of scissors, remove dead plant material all the way to the ground.
• Prepare to activate the sprinkler system.
• Aerate and fertilize the lawn.


• Mulch around flower and shrub beds to conserve moisture and keep down weeds.
• Mow lawn to no less than 2″ and never dut any more than one-third of the growth.
• Water plants, trees, shrubs and lawn infrequently, but thoroughly.
• After the 15th, put out annuals and perennials that have been overwintered indoors in pots.


• Continue to plant summer flowering bulbs, like cannas, dahlias, and gladioili (plant a few gladioli each week for continuous blooms throughout the summer).
• Fertilize annuals and perennials with nitrogen-based fertilizer.
• Check drip and lawn system. Remove any emitters that are overwatering, add emitters to areas where the soil is dry.


• Mow the lawn to no less than 2-1/2 ” in height, never cutting more than one-third of the growth.
• Do not use high nitrogen fertilizer on trees from the middle of July through February of next season.
• Make sure the garden is well-mulched to protect plants during the heat of the day.


• Make sure trees and shrubs get enough water during August.
• Pay particular attention to good watering practices this month. Stressed areas in the full sun, or on south or western slopes may need extra watering.
• Weed your garden frequently. Watch to see that weeds do not grow so large that they flower and drop seeds (causing more weeds!).


• Plant new perennials.
• Plant or transplant evergreens before the weather turns cool.
• Begin paying attention to the weather forecasts for predictions of early frosts. Cover plants if necessary.
• Water as needed. Be sure to check the ground so you don’t overwater.


• Plant hardy bulbs for spring blooming.
• Remove leaves and plant material. Put them in a “hot” compost pile (hotter than normal) or discard.
• Winterize the irrigation system.


• Mulch young or newly planted trees and shrubs. Wait until the end of the month when the ground is frozen.
• Purchase spring bulbs for forcing and indoor winter blooming.
• Cut back perennials from last year so they will bloom better.


• Add lighting to your landscape.
• Reduce watering of plants as the days become shorter. Plants can be overwatered if you are watering as much as you do in late spring, summer and early fall.
