How to Make Your Hydrangeas Bloom

Hydrangeas add so much beauty to the landscape with their beautiful blooms! But sometimes those beautiful blooms are nowhere to be seen. If you’re wondering why your Endless Summer® hydrangeas aren’t blooming, there are a few common reasons why this might happen.

Pruning at the Wrong Time

One of the most common mistakes people make is pruning their hydrangeas at the wrong time. Endless Summer® hydrangeas set their flower buds on old and new wood, so if you prune them in the fall or winter, you’ll be cutting off next year’s blooms.

The best time to prune hydrangeas is in late spring, after the danger of frost has passed. Wait until you see new green growth on the stems and then prune away any dead wood above those new buds. Always make sure to never prune your hydrangeas in fall though! Check out our seasonal pruning guide to learn more.

Using the Wrong Fertilizer or Not Fertilizing at All

Hydrangeas need nutrients to bloom, but just any fertilizer won’t do. Make sure you’re using a using a bloom boosting, slow-release, granular fertilizer and follow the directions on the packaging for how much to apply. Apply fertilizer in early spring and again in July to help promote the rebloom.

Avoid fertilizers that are high in nitrogen, as this can promote leaf growth at the expense of flowers. Head to our blog on fertilizing and amendments to learn even more.

Overwatering or Underwatering

Hydrangeas like moist soil, but they don’t want to sit in water. Overwatering can rot the roots and prevent the plant from flowering. On the other hand, underwatering can stress the plant and lead to a lack of blooms.

The best way to water your hydrangeas is to water them deeply when the soil is dry to the touch. Check out our blog on watering hydrangeas for more information.

Not Enough Sun or Too Much Sun

Endless Summer® hydrangeas need sunlight to bloom, but they don’t do well in all-day sun, especially in hot climates. The ideal spot for your hydrangea is one that gets morning sun with dappled afternoon shade. If your hydrangeas are getting too much sun, you may need to move them to a shadier location or provide some afternoon shade with a shade cloth.

Poor Soil Drainage

Hydrangeas need well-drained soil to thrive. If your soil is sandy or clay-heavy, it may not drain well enough for hydrangeas. You can improve drainage by amending your soil with compost or other organic matter. Head to our blog on understanding soil for more tips and tricks.
