Endless Summer® Pop Star™ Hydrangea Care
Find a location where Endless Summer Pop Star Hydrangea will receive full morning sun with dappled shade in the afternoon. The farther north you live, the more sun your Hydrangea can handle. The ideal soil is loam, with plenty of organic matter added to the existing garden soil such as garden compost to ensure drainage and nutrients. When planting, make sure the crown of the plant is even with the ground level. Avoid planting the crown too deep as it can potentially rot. Fertilize with a granular, slow-release fertilizer in spring with a slightly higher percentage of phosphorous to encourage bloom production.
Endless Summer Pop Star Hydrangeas prefer well-draining moist soil, but don’t allow the soil to get soggy. Overwatering can cause Hydrangea to produce fewer flowers. Always water the root area, and avoid splashing water on the leaves. Applying a layer of organic mulch will help conserve and maintain soil moisture and keep the ground cool. These plants require minimal pruning.
Endless Summer® Pop Star™ Hydrangea Spacing
Because of its tidy, compact size, gardeners have the flexibility to tuck it in mixed borders without its size overpowering the beds. Endless Summer Pop Star Hydrangea makes a lovely, colorful, flowering hedge when planted en masse. It can be planted in large containers too. Space plants approximately 30 inches apart to create a dense hedge.

"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
