There are many reasons why a kumquat will not flower. Some causes can be remedied in the short term, others need a little more time. But with a little patience, you will be able to get your kumquat to flower again.

If you just bought your kumquat, then you don't have to worry. If you take good care of your plant, it will definitely flower next year. She needs some time to get used to it.
Small cause - big effect
If the kumquat has been in your possession for a long time, then you should ask yourself the following questions: Did the kumquat have a sufficient hibernation with temperatures of a maximum of 10 °C and was it then slowly accustomed to the warmth and fertilized again?
Is the kumquat in a draught, for example near a constantly open window or the balcony door? Is the humidity high enough and the lime content in the soil and irrigation water low? All of these things can be the cause of your kumquat not flowering. However, they can be rectified quite easily.
Possible causes in brief:
- the plant is still too young
- insufficient hibernation
- too little fertilizer
- draft
- too low humidity
- Irrigation water that is too calcareous or soil that is too calcareous
Here's what you can do when your kumquat isn't flowering
If the plant is still too young, all you can do is wait. The same applies if your kumquat has not had an adequate winter rest. Then you will have to wait until next year for flowering. You can replace calcareous soil. If your tap water is very calcareous, use rainwater to water it. You can determine the lime content with test strips from the pharmacy or drugstore.
If your kumquat gets too much draft, then change its location. The same applies if the plant does not get enough light or heat. If the humidity is too low, you can gently spray your kumquat with lime-free water or place a container of water close by. Evaporation increases the humidity in the area.
tips and tricks
Without hibernation, your kumquat will not bloom the following year. So make sure you have cool, bright winter quarters.
