The ultimate summer guide for your hydrangea
It's the height of summer – the time when hydrangeas are at their most beautiful. With their exuberant flowers, long flowering period and versatility, it's no surprise that they are a favourite among gardening enthusiasts. But how do you keep them looking their best during the hot days? With these care tips, you can give your hydrangeas everything they need.
Sun or shade? How to choose the best spot
Give your hydrangea a spot with morning sun and shade later in the day. Too much bright sun can cause burnt leaves and/or flowers. A slightly sheltered spot works best.
Watering, especially during hot days
Hydrangeas have shallow roots and like moist soil. During dry periods, it is better to water thoroughly once or twice a week than a little every day. Spray close to the ground, preferably not on the leaves. Is your hydrangea in a pot? Check every other day to see if the soil is still moist. Dry? Water it!
Heat plan for hot summers
When temperatures are high, it is important that the soil around your hydrangea does not dry out. A layer of mulch, such as wood chips, compost or leaves, helps with this: it retains moisture, protects the roots from the heat and ensures an even temperature in the soil.
In extreme heat, provide young plants with extra shade using a cloth or parasol, especially during the hottest part of the day.
Top tip: Some hydrangeas are more resistant to drought and heat than others. Proven Winners® also tests for drought resistance and has found that Pink Annabelle®, Sublime Annabelle®, Little Lime and Lime Light Prime®, among others, are good at withstanding heat and drought. Flair & Flavours® Blueberry Cheesecake, Cotton Candy & Frozen Smoothie and the Gatsby® varieties are also good at withstanding these conditions.
Extra summer tips
- Collect rainwater for watering. It is softer than tap water, which hydrangeas love.
- Mix compost or coconut fibre into the soil to retain moisture longer.
- And: hold off on pruning or transplanting for now. It is better to do this in spring or autumn.
