What should I do in my garden in March?
- Cut back herbaceous perennials such as achilleas, asters, aquilegias, campanulas, centranthus, delphiniums, foxgloves, liatris, penstemons and salvias that are done flowering.
- Treat summer-weary lawns to a fertiliser tonic and re-sow bare patches.
- Trim hedges.
- Order bare-root roses from nurseries and specialist rose growers for planting during winter when dormant.
- Sow sweet-scented sweet peas around St Patrick’s Day, 17 March. It’s an Australian tradition! If you’re in a warmer northern area, hold off until early April instead.
- Start building a compost heap for autumn leaves.
- Prune fuschias and take cuttings for new plants.
- Feed lemon trees with a citrus-specific fertiliser.
- Plant spring-flowering bulbs in cooler regions.
- Encourage petunias and other annuals to continue flowering into autumn by clipping back and liquid fertilising.
