Instructions d'entretien

Hydrangea macrophylla requires indirect bright light and should be kept in moderate temperatures. It thrives in high humidity and needs to be watered regularly to keep the soil evenly moist. Avoid letting the soil dry out completely.

Sol

This plant prefers well-draining loamy soil that is rich in organic matter. The soil should be kept evenly moist but not waterlogged. A slightly acidic to neutral pH is ideal for optimal growth.

Engrais

Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and vibrant blooms.

Rempotage

Repot Hydrangea macrophylla every 2-3 years or when it outgrows its current container. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repot in early spring before new growth begins.

Propagation

Propagate Hydrangea macrophylla through softwood cuttings taken in late spring or early summer. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the cuttings in a humid environment until they root.

Taille

Prune Hydrangea macrophylla in late winter or early spring before new growth starts. Remove dead or weak stems and shape the plant to maintain its form. Avoid heavy pruning as it can reduce flowering.

Toxicité

Hydrangea macrophylla is toxic to pets and humans if ingested. All parts of the plant contain cyanogenic glycosides, which can cause symptoms like vomiting, diarrhea, and lethargy. Keep the plant out of reach of children and pets.

Supplémentaire

To change the color of the flowers, you can adjust the soil pH. For blue flowers, make the soil more acidic by adding aluminum sulfate. For pink flowers, make the soil more alkaline by adding lime.
