What you do now will pay off all season long.
#1 - Wake up your lawn with a soak—not a splash—of water. Since the past winter has been very dry, we need to apply water like Mother Nature does during an ideal springtime. Spring rains, that soak in and rain again in seven-day to ten-day cycles, are great for the lawn. Soak the lawn well and allow the top ½ inch of the soil to dry out. Then soak it again.
#2 - Aerate. After an early soaking, aerate the turf with an aeration machine. The moisture makes the ground soft for the aerator to pull out good-sized plugs from the turf and roots. The holes left behind let water, air and nutrients into the root zone where they do the most good. Water again soon after aerating as the holes will make the ground dry out faster than before.
Leave the plugs on top of the grass. The lawnmower will have them all broken up before the party—and they’ll add nutrients in the meantime as they dissolve.
#3 - Fertilize. After aerating is the best time to fertilize because the aeration holes have made way for nutrients to head straight down to the roots. Spring is when grass builds the roots that will support the lawn all season long. Think about those roots gobbling up fertilizer, and know they’re doing their job to get ready for the party.
#4 – Un-welcome the weeds. Nothing detracts more from an otherwise beautiful lawn than yellow dandelion flowers or other weeds. Get after these party-crashers early, and you will have fewer weeds to deal with as the season goes on.
