Pacific Northwest Gardening in the Merry Month of March
- Weed, weed, weed!
- Add compost or other soil amendments to prepare for spring planting.
- Prune roses and clean up all debris beneath them.
- Prune perennials with hollow stems like phygelius and fuchsia.
- Remove mulch that was protecting plants from winter cold.
- Plant cool season crops like lettuce, radish, peas, cauliflower, cabbage and leafy greens.
- Divide summer blooming perennials, wait on spring blooming perennials until after they flower.
- Start the slug patrol. Keep them in check early by tossing them in a bucket of soapy water or use an iron phosphate product.
- Cut faded flowers from heath (winter heathers).
- Plant bare trees and fruit such as blueberries, raspberries and currants.
- Fertilize trees, shrubs and perennials with a good organic fertilizer.
- Bare root roses. Choose disease resistant varieties for our climate.
The average last frost March 22 but the safe date is April 15 in Western Washington.
