Hibiscus ‘Summerific’ cultivars respond to generous fertilisers. Apply a dressing each spring and if it can conveniently done mulch around them for the summer. Keep the ground moist, water deeply when needed. As the plant begins to close down for the winter recess prune back almost to ground level. This pruning must be done before spring comes. Make sure you have a stake near the plant to identify where it is during winter. As the plant begins to grow in early spring it will send up a shoot, sometimes several which need tip pruning to fill out the plant. This will give you more flowers for the season. Overall a plant that is easy to manage in the garden. Any insect pests will be the usual ones seen normally in gardens, treat in the usual way.
