If the hibiscus doesn't want to bloom, what to do? In this article, we provide information on how you can prevent the blooming.

The hibiscus develops a great bloom on a sunny, protected location with nutrient-rich soil.

It's annoying when the hoped-for hibiscus flower doesn't appear. This affects the outdoor hibiscus, as well as the plants in the room or in the tub on the terrace.

Although the flower bud is already there, the flower shrub is very sensitive to disturbances and suddenly throws the bud off. So success depends on how carefully you handle the hibiscus. The following information may help you here.

What is bothering the garden hibiscus?

The exotic shrub from Asia places high demands on its location and the nutrient content of the soil. There are two main reasons why this garden shrub loses its flower buds and thus refuses to bloom.

❶ Maybe the wrong location?

  • When planting, make sure that you place your garden hibuskus in a sunny location. Your shrub can easily get by even with partial shade.
  • Therefore, you should definitely avoid a shady and drafty place for your outdoor hibiscus. A lack of sunlight and temperature fluctuations due to drafts prevent hibiscus blooming.

❷ Possibly a lack of nutrients?

  • A nutrient-rich soil is important for the garden hibiscus. It is best to put the young plant in a mixture of sand and compost. Then fertilize it every two weeks with a special liquid fertilizer (available here).
  • A lush bloom requires a healthy plant framework and foliage. It is therefore advisable to fertilize the outdoor hibiscus with patent potash (Kalimagnesia) from the end of August to mid-September. Potash promotes plant growth and magnesium ensures a healthy leaf.

What affects the room or bucket hibiscus

The hibiscus in the room or on the terrace is particularly sensitive to moisture, temperature and light conditions. You should therefore ensure that these conditions are strictly observed.

❶ Is the water balance correct?

  • The disturbance in the water balance can also be a cause for the loss of flowering. After all, the hibiscus in the room and on the terrace is very demanding when it comes to watering. Give the hibiscus too much water, then it will react with a growth disorder and subsequent budding. Too much drought has the same consequences.
  • Keep the plant evenly moist. However, you may only water again when the upper layer of soil has dried. It is also recommended to use stale water at room temperature for watering.
  • Be sure to pour away excess water in the planter, otherwise it will cause waterlogging and rotting.

❷ Is the plant in drafts?

  • Drafts can lead to greater temperature fluctuations, especially in unstable weather. The hibiscus on the room window and on the terrace reacts sensitively to this and then throws off the flower buds. If you ventilate, you should definitely avoid draft.
  • When choosing the location on the terrace, check beforehand what the wind conditions are like. It can be airy, but not drafty.

❸ Does the hibiscus get enough light?
