Panicle hydrangeas are very floriferous, but sometimes the eagerly awaited bloom is a long time coming. In this article you will find out which causes are responsible for this and how you can still get your shrub to bloom.

A lack of nutrients or a wrong location can mean that the panicle hydrangea does not bloom

Young panicle hydrangeas often do not bloom yet

Even if the young hydrangea was already flowering in the pot when you bought it, it can still pause for a while after planting - young flowering bushes often only flower after a few years of standing anyway. So don't be surprised if the panicle hydrangea you planted last year grows splendidly and develops wonderful dark green foliage, but no flowers. If you can rule out other causes, then only patience will help.

Wrong location prevents flowering

One of the most common causes of panicle hydrangeas not flowering is simply the wrong location. In some garden centers, this type of hydrangea is advertised as "shade-tolerant" in a sales-promotional manner, whereupon it naturally does not bloom if planted in a shady place in the garden. In contrast to most other hydrangeas, panicle hydrangeas actually need at least a semi-shady location, although they also tolerate sunny and full sun well - always provided the water supply is right. Panicle hydrangeas planted in the sun must be watered more abundantly than specimens that are in partial shade.

Panicle hydrangea suffers from nutrient deficiencies

Last but not least, a lack of nutrients can also mean that the panicle hydrangea does not bloom. This can occur either as a result of unsuitable soil conditions (sandy or calcareous soil) or an insufficient supply of nutrients. Panicle hydrangeas not only need a lot of water, but also a continuous supply of the right mix of nutrients. Regular mulching and the additional application of mineral fertilizers are useful for plant health, with phosphorus in particular stimulating flowering.

tips and tricks

If you have a walnut tree in your garden, you can be happy. The fallen leaves in autumn can be used as an organic fertilizer for hydrangeas, rhododendrons and other plants with a preference for acidic soil. In the fall, mulch the root area of your hydrangea thickly with the (preferably wet) walnut leaves. Compost more leaves together with (rhododendron) soil until spring, because then the shrubs will get another big portion to start the growing season. P.S. Don't be spooked by claims that walnut foliage is non-compostable. Experience has shown that the foliage rots within a year.
