Well grown plant in a pot - deep red rose ruffled flowers Ist picture shows the flower. POSITION Full sun. Grows best in fertile fairly free-draining soil in a sheltered, sunny spot. PLANTING Dig a hole that is at least twice as wide and twice as deep as the pot the plant came in. Carefully remove the pot from your hibiscus plant and gently place the plant in the hole. Your hibiscus should be planted at the same level as it was in your pot. When back filling mix your top soil with compost and sheep pellets. Firm in and then water deeply. If you’re in heavier soils you can also plant into a slight mound to help improve the drainage. CARE Water deeply at least once a week during the hotter months. Mulch plant to help suppress weeds and reduce water loss. Prune in late spring when all chances of frosts have gone.
