Reasons and solutions for hydrangea not blooming

Hydrangea is a very ornamental flower . It is made up of small flowers that form a ball shape. The flowers are clustered together and are very beautiful. It is suitable for planting in the courtyard. So what is the reason why hydrangeas do not bloom when planted? How to solve it? Let’s learn more about it below.

1. Insufficient light

Hydrangea is a sun-loving plant, and lack of sunlight is one of the main reasons for not flowering.

Solution: Hydrangeas need to be given as much diffuse light as possible. Generally, they should be properly shaded during the hot summer, at noon and in the afternoon. More light should be given in other seasons. If the temperature is not high and the light is not particularly strong, hydrangeas can bask in the sun all day long.

2. Improper watering

Soil drought or waterlogging will affect the normal growth of hydrangea, thus affecting the opening of flowers.

Solution: Moderate watering is key to keeping hydrangeas blooming, but avoid standing water. During the growing season, especially around flowering, keep the soil moist, but not overly wet.

3. Malnutrition

Lack of nutrients in the soil, especially phosphorus and potassium, may affect the formation of flower buds and flowering.

Solution: Do the correct fertilization work. When fertilizing hydrangeas, you can generally use organic fertilizer or compound fertilizer . In the early stages of growth, more nitrogen fertilizer should be applied, and organic fertilizer should be applied once a month. During the flower bud differentiation and bud formation period, spray 0.1% to 0.2% potassium dihydrogen phosphate on the leaves 2 to 3 times.

4. Improper pruning

Over-pruning or pruning at the wrong time may remove potential flower buds and prevent flowers from opening normally.

Solution: Be sure to master the method when pruning. Generally, varieties such as Endless Summer, Hydrangea paniculata and Hydrangea paniculata can bloom on both new and old branches, and can be pruned and topped at any time without affecting their flowering performance. However, for varieties such as hydrangeas that rely on the top of old branches to bloom, you need to wait for the new branches to age for a year before buds form from the top and bloom, so pruning needs to be done with caution.

5. Age Issues

The growth cycle of a hydrangea may affect when it blooms. Hydrangeas usually take a certain number of years to grow before they start to bloom on a large scale. Generally speaking, hydrangea plants that are one to two years old may still be in the growth stage and have not yet reached the stage of large-scale flowering.

Solution: Choose the right hydrangea variety. If it is a late blooming variety, you will just have to wait patiently.

6. Unsuitable environment

Environmental problems such as temperatures that are too high or too low, unsuitable soil, etc. may affect the flowering of hydrangeas.

Solution: During the growth process of hydrangea, observe the condition of the plant in time, deal with problems in time, and provide it with a suitable growth environment.

The above is an introduction to the reasons why hydrangeas do not bloom. If you take the correct solutions to these reasons, I believe that the hydrangeas will regain their vitality and bloom beautiful flowers.
