Things to do in April

  • Allow foliage of spring-flowering bulbs to brown and die down before removing.

  • Western Oregon: Prune and shape or thin spring-blooming shrubs and trees after blossoms fade.

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?
