Carissa Holly

Does holly bush need very much sun

Carissa Holly (Ilex cornuta 'Carissa') prefers full sun to partial shade. While it can tolerate some shade, it performs best and maintains its dense, compact growth when it receives ample sunlight.

Sunlight Requirements:

1. Full Sun: Ideally, Carissa Holly should receive at least 6 hours of direct sunlight per day. This helps the plant develop its best form and the most vibrant leaf color.

2. Partial Shade: The plant can still grow well with 3-6 hours of sunlight per day, especially in hot climates where some afternoon shade can protect it from intense heat. However, too much shade may cause the plant to become leggy, with fewer leaves and a more open growth habit.

3. Dense Shade: Carissa Holly does not thrive in dense shade. In very low light conditions, the plant may struggle, leading to poor growth and reduced vigor.

In summary, while Carissa Holly is somewhat adaptable, it will perform best with plenty of sunlight. If possible, choose a location that offers full sun or at least partial shade for optimal growth and appearance.

How far should we space a one gallon pot.

When planting one-gallon pots of Carissa Holly, they should be spaced about 2 to 3 feet apart. This spacing allows the plants to grow and fill in without overcrowding. Carissa Holly typically reaches a mature width of 3 to 4 feet, so proper spacing ensures healthy growth and allows for air circulation, reducing the risk of disease. For a dense hedge, you can plant them closer to 2 feet apart, but for more natural, individual growth, 3 feet apart is recommended.
