Carissa's do not need pruning. Cut dead or broken branches with hand pruners.

Plant Carissa Holly in well-drained soil in either full sun or partial shade. This is one of the best choices among evergreen shrubs for foundation plantings. It is exceptionally hardy, very long-lived, and is as low maintenance as a shrub can get.

To plant, dig a hole no deeper than the root ball and two to three times the width of the root ball and fill it with water. If the hole drains within a few hours, you have good drainage. If the water is still standing 12 hours later, improve the drainage in your bed, perhaps by establishing a raised bed. Turn and break up the soil removed from the planting hole. If the native soil is compacted or heavy clay amend with organic compost or a good soil amendment at a 50/50 ratio. Remove your plant from its container and carefully but firmly loosen the root ball. Set the plant into the hole you've prepared, making sure the top of the root ball is slightly above the soil level. Pull your backfill soil mixture around the root ball in the hole, tamping as you go to remove air pockets. Then water thoroughly and cover with a one to two-inch layer of mulch

Carissa holly prefer an acid soil with a pH in the range of 5 to 7. I fertilize hollies in spring and again in late summer with a well-balanced shrub & tree type fertilizer that includes a micronutrient package containing iron and/or sulfur. If the foliage on your holly develop chlorosis (yellowing of leaves), due to soil that is too alkaline, you can apply additional amounts of chelated iron and/or soil sulfur to lower soil pH, making it more acidic.
