If your lawn sinks slightly underfoot in summer, like walking across a thin mattress, the cause sits just below the green blades. That soft, springy feeling points to thatch, a dense band of dead and living stems packed between the…
A brown summer lawn looks dead, but most of the time it is asleep. Cool season grasses shut down their leaves in heat and drought to protect the crown, the living heart of each plant, and they wait for cooler,…
A lawn that looked healthy on Friday and skeletal by Monday has almost always met one thing in late summer: armyworm caterpillars feeding in numbers. They move across turf in a loose front, stripping the green from grass blades as…

The patch of lawn under the big tree at the side of the garden is the single most frustrating piece of turf in any garden. It thins. It moss-fills. It stays sparse no matter how much you seed, feed, or…
Two lawns sit side by side in the same dry July. One browns off in a week. The other stays green for a month without a drop of extra water. The difference is almost entirely underground, in how deep the…
Small dark spots on your grass blades in warm, muggy weather are the opening move of melting out, a fungal disease that can thin a thick lawn to a patchy mess in a fortnight. The spots themselves do limited harm.…
