If a kumquat tree loses leaves in winter, that's perfectly normal. It serves to protect the plant. The metabolism is shut down. Less nutrients are absorbed, so not as many nutrients must be used up. The darker the location, the more leaves the plant will lose. That is why a kumquat should be as bright as possible in winter.

In summer a kumquat usually loses its leaves if the watering is not optimal. Then it is poured either too much or too little, or the irrigation water contains too much lime. Another reason could be insufficient humidity.
What do you do when the kumquat loses its leaves?
If your kumquat is losing its leaves, check your watering behavior first. The kumquat needs plenty of water, but it doesn't like too much either. Above all, it does not tolerate waterlogging, then its roots rot. Does the plant pot have a drainage layer or is the drain blocked? Then you should take remedial action immediately.
If the humidity is too low, it will help to carefully spray the plant with lime-free water or to place a container filled with water near the plant. The evaporation increases the humidity. Another possibility is to put the bucket in a larger bucket filled with water, but elevated so that the excess irrigation water can run off freely and no waterlogging forms.
If you want to prevent leaf loss in winter, make sure that the location is as bright as possible. It does need the cool temperatures during hibernation so that it blooms again the following year. But she is not used to the dark season and the associated lack of light from her home.
The essentials in brief:
- Check the lime content in the irrigation water
- Check the pouring amount
- Check humidity
- create bright winter quarters
