Sun or shade? How to find the best spot
Hydrangeas do best in a spot with morning sun and shade later in the day. Too much direct-sun can scorch the leaves and flowers. A lightly sheltered position is ideal.
Watering your Hydrangea, especially on hot days
Hydrangeas have shallow roots and prefer moist soil. During dry spells, it’s better to water thoroughly once or twice a week rather than a little each day. Water at the base of the plant, avoiding the foliage. If your hydrangea is in a container, check the soil every other day. If it’s dry, grab your watering can!
Heat plan for hot summers
When temperatures rise, it’s crucial to prevent the soil around your hydrangeas from drying out. A mulch layer—such as wood chips, compost or leaves—helps retain moisture, protects roots from the heat and keeps the soil temperature stable. For young plants, consider providing extra shade during extreme heat using a cloth or parasol, especially during the hottest part of the day.
Top tip: Some hydrangeas are more tolerant of heat and drought than others. Proven Winners® also tests for drought resistance and has found that Pink Annabelle®, Sublime Annabelle®, Little Lime, and Limelight Prime® handle heat and dryness well. The Flair & Flavours® varieties Blueberry Cheesecake, Cotton Candy, Frozen Smoothie and the Gatsby® series also perform strongly under warm, dry conditions.
More summer tips
- Collect rainwater for watering – it’s softer than tap water, and hydrangeas love it.
- Mix compost or coconut fibre into the soil to help retain moisture longer.
- And: hold off on pruning or transplanting – it’s better to do that in spring or autumn.
