Perennial Maintenance Tips

Ensure perennials are planted in nutrient-rich soil and water them deeply but infrequently to encourage deep root growth. Control pests like aphids by using natural predators or insecticidal soap. Fertilize perennials with a slow-release fertilizer in the spring and early summer. Deadhead spent blooms to encourage continuous flowering and prune dead foliage to maintain plant health. Harvest perennial herbs in the morning when the oils are most concentrated for the best flavor.
