Timely Tips

March 8

Perennials: As the weather permits and the ground is not soggy, begin to remove weeds and dead foliage from flower beds and to loosen winter mulch to ease the way for plants to emerge. Where it won’t show, consider leaving some leaves that may be protecting overwintering pollinators. Trim away brown hellebore leaves to expose the flowers.

Flowers: Clear debris around emerging snowdrops, crocus and other early flowers. Take special care around delicate flowers in warm locations where these are already blooming. Create space for emerging daffodils and other spring bulbs to expand.

Fruits and Vegetables: Harvest any usable root vegetables still in the ground, such as beets, carrots and parsnips, before they sprout new green growth. Dig horseradish before it flowers. If you have space, you can leave a few carrots to flower where they will attract pollinators and other beneficials to the garden. Overwintering arugula, broccoli, kale and other cabbage family plants will also develop edible flowers in spring that attract pollinators and beneficials.

Trees and Shrubs: If you shielded evergreens with a burlap screen for winter protection, you may begin to remove it as the weather moderates.

Lawns: Stay off the lawn when its wet. Heavy foot traffic can lead to compacted soil, which drains poorly and can prevent roots from growing.

Houseplants: Prune houseplants that have grown leggy.
