Highclere holly

Highclere holly needs regular watering to thrive and should never be allowed to dry out completely. Generally, this plant should be watered once per week. When watering, ensure that you provide the plant with enough water to thoroughly moisten the soil, and water deeply so that it reaches the roots. Watering should also be done in the morning, and not in the evening to avoid fungal diseases. In the summer months, you may need to water more frequently or add mulch to the soil to help the soil retain moisture. During winter, when temperatures are cooler, you may need to water less frequently.

Highclere holly (Ilex x altaclerensis) typically requires full sun exposure for the best growth and fruit production. Plants should receive at least 6 hours of direct sunlight to remain healthy and thrive. If inadequate sun exposure is given to the plant, the leaves may become pale or yellowed. The Highclere holly grows best when in full sun during the spring and summer months. Ideally, the plant should receive exposure to the morning sun, with some protection from the afternoon sun. During the winter, the plant should be placed in an area that still receives 5 to 6 hours of direct sunlight to prevent dormancy.

Highclere holly should be pruned twice annually, once in early spring after the threat of frost has passed and once after the summer season. During both pruning sessions, only dead, diseased, and overcrowded branches should be removed. It is important not to remove too much of the shrub in 1 session, as this can cause further stress and damage. In the springtime, prune the holly to encourage new shoots and growth by removing the winter-damaged branches, as well as any weak branches smaller than 1/4 inch in diameter. If there is strong growth from the previous season, it can be cut back by 1/3. In the late summer, prune new growth back by 1/3 to produce a more compact shape. This technique is also used to control the size of the shrub. Prune back side shoots close to the main branch so that the shrub maintains a natural shape. Lastly, as with all Ilex species, caution needs to be taken to avoid pruning more than 25% of any plant in any 1 session, as this can cause shock and damage to the plant.
