• Good Drainage : Make sure your planters have adequate drainage holes to allow excess water to drain away and prevent root rot.
• Regular Watering : Despite their hardiness, these plants still need water, especially during dry spells. Check the soil moisture regularly.
• Feeding : Feed your plants regularly with an organic fertilizer, specifically formulated for evergreens, to keep them healthy and strong.
• Pruning : Evergreens generally require little pruning, but remove dead branches and protruding shoots to keep the plant looking neat and compact. Pruning is best done in late spring or early summer.
