However, there’s a catch on this practice. Check your hardiness zone, and if your state is in zone 4 or 5, you don’t have to prune unless necessary. As mentioned earlier, you can prune immediately after blooming. 

Pruning in spring is not a common practice. Instead, you maintain your plants by removing the dead stems. If you need to revive your damaged or old hydrangeas, prune all the branches down to the base. 

The plants won’t flower in the upcoming season, but this will encourage healthier blooms for years later on. Some gardeners also recommend pruning in May to help the buds that survived winter to emerge. You can also deadhead the spent flowers to encourage the setting of buds for blooming throughout the season.

If you live in the northern part of the country, you should also learn how to properly overwinter endless summer hydrangeas.

Do not immediately get discouraged if the plant takes time to grow from the base or old branches. The heat in late spring shall help the plants grow. Once this happens, prune back the old branches.



One of the reasons why endless summer hydrangeas are well-loved is that they bloom for a long time and grow both on old and new stems. The greenhouse already helps in maximizing this characteristic, but you must learn when to cut back endless summer hydrangeas. In general, you cut the plants back when a flowering stem fades.

However, you can best control the perennials’ size and shape when you cut them back after they finish blooming. This is typically in early fall. Additionally, take the time to prune and overwinter your hydrangeas to keep them thriving properly and your greenhouse colorful. 

Endless summer hydrangeas are also typically forgiving if you prune at the wrong time, and recently planted perennials will even thrive best if you leave then alone.
