Why is my viburnum hydrangea blooming little or not at all?
Snowball hydrangeas, especially their best-known representative, the “Annabelle” variety, are known for their many large flowers. If the flowering slows down or stops in your area, it is because the hydrangea is missing something. Possible causes can be:
- Wrong location
- Incorrect pruning
- Nutrient deficiency and corresponding deficiency symptoms
- too high pH value
- Droughtness
- Frost
How can I encourage the blooming of my viburnum hydrangeas?
After you have identified the cause of the lack of flowering, you can take specific action against it.
- Make sure you water your hydrangea enough. At the same time, the water should be able to drain well to avoid waterlogging.
- Check if the location ispartially shaded. In full sun the buds can burn. Even if the location is too shady, the flowers may not bloom.
- Fertilize at least once a year with a hydrangea fertilizer or alternative home remedies.
- Measure the pH value of the soil and adjust it if necessary with appropriate fertilization.
- Protect your hydrangeas from persistent frost, for example with fleece.
Tip
Should I cut off the flowers after flowering?
Snowball hydrangeas form their shoots on new wood. This means that you can be a little more courageous when pruning than, for example, farmer's hydrangeas that sprout in old wood. For this reason, you can cut back the snowball hydrangeas either in autumn or in spring. Pruning later has the advantage that the hydrangea is better protected from frost over the winter.
