Instructions d'entretien

American holly requires moderate temperatures and should be planted in an area that receives bright, direct sunlight for optimal growth. It prefers moderate humidity levels and should be watered regularly to keep the soil partially moist. The plant can tolerate a range of temperatures but thrives best in temperate climates.

Sol

American holly prefers well-draining loamy soil with a slightly acidic pH. The soil should be kept partially moist but not waterlogged. Good drainage is essential to prevent root rot.

Engrais

A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied in the spring to promote healthy growth. Fertilize once a year, taking care not to over-fertilize, as this can harm the plant.

Rempotage

As a tree, American holly is not typically repotted. However, if grown in a container, it should be repotted every few years to refresh the soil and provide more space for root growth. Repot in the spring before new growth begins.

Propagation

American holly can be propagated through seeds or cuttings. Seeds should be stratified before planting, while cuttings can be taken in late summer. Use a rooting hormone to increase the chances of successful propagation.

Taille

Pruning is required to maintain the shape and health of the plant. Prune in late winter or early spring before new growth begins. Remove any dead or diseased branches and shape the plant as desired.

Toxicité

American holly is toxic to pets and humans if ingested. The berries contain saponins, which can cause vomiting and diarrhea. Keep the plant out of reach of children and pets.
