Hydrangea care and planting tips for autumn

September and autumn are critical periods for the care and planting of hydrangeas. To ensure healthy growth and vibrant blooms in the spring, gardeners should focus on moisture and proper maintenance during the transition from summer to winter.

For existing plants, regular watering is essential if rainfall is insufficient, as adequate moisture helps the plant withstand winter temperatures. It is also important to remove fallen leaves from the base of the shrub to prevent pests and diseases from overwintering. When fertilizing, gardeners should avoid high-nitrogen products, which can trigger new growth that will not harden before the frost. Additionally, intensive pruning should be avoided in September to prevent the accidental removal of next year's flower buds.

Autumn is considered an ideal time for planting new hydrangeas. According to expert Loreijn Balato, the primary goal is root development, which is well-supported by the warmer soil and increased autumn rainfall. To ensure success, new plants should be established at least six weeks before the first frost. Ideally, hydrangeas should be placed in locations that offer relief from the harshest afternoon sun.
