Question: My hydrangea isn’t blooming. What can I do? When is the right time to trim? Fall? Spring?
Answer: Hydrangeas are such a beautiful plant but to get them to rebloom is a little bit tricky. Some plants like to be cut back completely whereas other plants just like to be thinned out. Hydrangeas are one of those plants that likes to be thinned out. This means that you want to cut out all the weaker stems. You also want to deadhead your hydrangea once the blooms start fading. Also, pruning your hydrangea depends on if blooms develop off of new wood or old wood. Hydrangeas that bloom off of new wood is Hydrangea paniculata and Hydrangea arborescence. You can prune these species in the late fall because they will develop their blooms off of new growth. Hydrangea macrophylla and Hydrangea quercifolia develop blooms off of old wood. You can prune these after they bloom in the summer because they develop their blooms for next year in August.
Hydrangeas also likes acidic soil. You may want to check the pH in the soil. If it’s too high you will need to lower it by using soil acidifier to bring that pH down. I also suggest using Espoma’s Holly Tone fertilizer because it’s for your acidic loving plants. Make sure you fertilize in the fall as your plant is going into dormancy and in the spring as your plant is coming out of dormancy and starting to actively grow.
