After the cooler temperature of winter, spring is a critical time for practices that will help maintain health and help ensure a lush growing season. Here's a helpful checklist:
- Cut back herbaceous plants. Any remaining winter interest perennials can be cut back now.
- Remove dead plant material, dead leaves and dead branches.
- Edge planting beds in preparation for new mulch. Create a shallow edge to avoid damaging existing plant roots and do not place soil against the stem of woody plants.
- Top-dress beds with new mulch. Don't exceed a 3-4 inch layer and keep mulch away from woody plants' stems.
- Apply dormant horticultural oil sprays just before new growth begins.
- Fertilize plants and adjust soil pH as needed.
- Monitor for early spring insects.
- Prune plant material that blooms on new wood.
- Plant trees and shrubs. If you live in an area experiencing a drought, delay planting until the fall.
