Q: I forgot to fertilize last fall! Am I doomed?
— John Farrow, Boise, Idaho
A: If you didn't fertilize last fall, resist the urge to double up in the spring. Dumping more fertilizer than the lawn needs in the spring is wasteful and can burn your turf. Instead, spread 32-0-4 grass fertilizer after the first mowing, then again four to six weeks later. Organic lawn food, such as corn-gluten meal or a mix of feather, bone, and blood meals, works more slowly than synthetic fertilizers, so the lawn will take an extra week to green up.
Shown: TOH landscape contractor Roger Cook relies on a broadcast spreader to add fertilizer because it reduces the chance of missing a section, which can lead to unsightly growth patterns.
