Ilex cornuta 'Carissa'

Overall Description

Carissa Holly is very widely used - low to mid level foreground or hedge shrub that is known for its extremely glossy, dark green foliage... and also for the very pronounced (and sharp) terminal spine or needle at the very tip of each & every leaf. Leaves are 2" - 3" long by slightly over 1" wide on the average and, as mentioned, extremely glossy dark green on the top sides - dull olive green underneath. Foliage is also very sturdy... almost a plastic or rubbery consistency.

Responds very well to trimming, and can be shaped / maintained at a wide range of heights & widths through occasional shearing.

--Deer Resistance Rating :
Lowest Resistance [ 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
