Things to do in April

  • Apply commercial fertilizers, manure, or compost to cane, bush (gooseberries, currants, and blueberries), and trailing berries.

  • Cut back ornamental grasses to a few inches above the ground, in early spring.

  • Central/Eastern Oregon: If snow mold was a problem, scratch surface. If turf damage is severe, seed with Kentucky bluegrass.

Question of the Week

For the last 8-10 yrs I've been good about pruning my climbing rosebush and its has thrived. This year I didn't get to it in February, as I usually do, now it's April and not looking great. Will it harm the bush if I do my usual pruning in April?
