1) Sprinkler startup and coverage checkBefore you rely on irrigation, confirm each zone is working, heads are straight, and there are no leaks. A quick “cup test” (a few identical containers around a zone) helps you spot uneven coverage.
2) Apply pre-emergent at the right time
Pre-emergent helps stop many annual weeds before they sprout. Timing matters more than “how strong” the product is. If you miss the window, you’re forced into more post-emergent weed control later.
3) Start fertilization with a plan (not guesswork)
Early feeding supports spring green-up, but too much nitrogen too fast can cause top growth that’s hard to mow and more vulnerable to stress. A measured, slow-release approach works well for Treasure Valley lawns.
4) Mow higher than you think
For most cool-season lawns, a taller mowing height shades soil, supports deeper roots, and reduces weed pressure. Avoid “scalping” early spring grass—it sets you back for weeks.
5) Consider spring aeration only if needed
If your lawn is heavily compacted or you missed fall aeration, spring core aeration can help. In our area, spring aeration is commonly done around April/May when grass is actively growing.
