FAQs
What makes the Endless Summer Bloomstruck® hydrangea unique?
Because of BloomStruck’s extremely strong hydrangea stems, above average heat tolerance and great disease resistance – especially to powdery mildew – it is a perfect combination of beauty and hardiness for your garden!
My hydrangeas have brown dry spots on the leaves and brown petals on the bloom. What do I need to do to make the hydrangeas healthier?
If the spot is round and brown with a red to purple ring, you likely have Anthracnose. Remove the affected leaves and dispose away from your plants. Treat with a fungicide and repeat as necessary. If the margins of the leaves fade from green to grey and then turn brown, the plants were dry for too long. If the petals of the flowers turn brown at the tip, not enough water was applied. Both the leaves and the flowers will show lack of water very quickly.
I live in an area that gets a lot of snow during the winter. Should I prune Endless Summer Hydrangeas back like I do with my other hydrangea bushes? What else should I do to protect them from the freezing winter months?
The great thing about Endless Summer® hydrangeas is that you don’t need to prune them back to the base like other hydrangeas. Since they bloom on previous years’ growth AND the new season’s growth, you can leave them all winter long to achieve double the blooms next spring. Do NOT prune the hydrangea back in fall. Leaving the fall blooms on your plants over the winter provides winter interest, and ensures you aren’t removing buds that will become flowers in the spring and summer. Leaves, wood mulch and/or straw are good options to insulate your plants. Mound the mulch or leaves around your plants at least 12” high to protect the flower buds that will bloom early next year.
