Spring Lawn Care on Vashon Island

Spring time landscaping tasks on Vashon Island Washington

Our little island explodes with growth come Spring time. It is during this time that some very specific gardening tasks should be started and others completed. 

Below is a list of tasks that you should consider performing once spring hits on Vashon Island. Of course, our crews can do as much or as little as you would like, but make no mistake, if you fail to accomplish these tasks, your lawn and garden could get out of control, fast! 


When you rake your property up at the beginning of Spring, it removes those old fall leaves and grass blades that did not survive winter.


Fill bare or thin spots in the lawn by overseeding. Late spring is the best time to overseed warm-season grass. Fall is the ideal time for cool-season grass, but in colder regions, spot-seeding small areas in spring yields good results. When you overseed, apply a slow-release nitrogen fertilizer. Five weeks after overseeding, apply a quick-release nitrogen feed.


Vital for a truly healthy lawn, aeration is the solution for compacted soil. How often you should aerate your lawn depends on soil type and how you use your lawn. Late spring to early summer is the right time to aerate warm-season grasses. 


Spring is the right time to dethatch turf. Aim for early spring for cool-season grasses and late spring to early summer for warm-season grasses. 


If Crabgrass is a problem in your lawn, apply pre-emergent herbicides to keep seeds that dropped last summer from germinating. Timing is critical for this application. Most product bags have application timing advice.


Apply grass fertilizer for spring roughly three weeks after grass starts greening (that usually corresponds to the time following two or three mowings). Apply lawn fertilizer for spring too early and you risk feeding weeds and creating fertilizer runoff. Too-early applications also trigger lush blade growth at a time when roots may not have started their spring growth spurt.


Spring irrigation needs vary by region. For mountain and arid desert areas, continue watering lawns as you have been through winter, increasing irrigation frequency as temperatures climb, as spring winds build in the Southwest, and if spring rainfall is scarce in mountain areas.

In the North, Midwest and Pacific Northwest areas, spring rains typically provide sufficient moisture for awakening lawns. Avoid the temptation to water as a means of greening up grass. Let it green up naturally and irrigate only if rains are scarce and grass shows signs of dehydration.


Start mowing when the ground is dry enough and grass is long enough to require cutting. Cut at the proper height for your type of grass. Avoid mowing too low. Grass cut too short allows sunlight to reach soil, encouraging weed seeds to germinate.
