Things to do in April

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

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

  • Plant gladioli, hardy transplants of alyssum, phlox, and marigolds, if weather and soil conditions permit.

Gardening Tips

Go through leftover garden seeds
If garden seeds are kept dry and cool, they last longer than in warmer and more humid conditions.
Less toxic iron phosphate slug bait proves effective
OSU research indicates that the less toxic iron phosphate containing slug baits are as effective as those with metaldehyde.
How to control indoor plant pests without toxic chemicals
Winter is a good time to check indoor plants for pests including mites, thrips, mealybugs, scales, whiteflies and aphids.
Grapes on a vine.
Prune your grape vines heavily in winter
When home gardeners prune their grapes this winter, they should remove the majority of wood produced the previous season. About 90 percent is pruned off.

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?
