"Grass roots keep growing until the ground gets down to around 40 degrees," says TOH
landscape contractor Roger Cook, "so this is a good time to feed them." Apply a high-phosphorus (12-25-12) mix to lawns in fall to encourage roots, so turf greens up earlier in spring.
It's also a good time to seed a new lawn
, start a compost pile
, and trim shrubs and trees
