My kumquat tree loses all the leaves. Will they come back or what can I do??
There can be a few different reasons for the leaves to drop from your tree.
A kumquat tree needs all day sun, soil that stays moist but drains and a regular fertilizer schedule.
Watering is key with extra water during hot and dry spells.
Aphids are common on Kumquat Trees and can cause leaf damage and eventual leaf drop. Examine the tree for signs of the insects.
Neem Oil can be used to treat these insects.
Citrus Canker can also attack a Kumquat Tree causing scaring on the branches and trunk.
Liquid cooper fungicide is used to treat this fungus.

My kumquat tree has produced orange. It is now producing green fruits looking like a lime and when I cut into it, it looks like there are some seeds in it. Can you help me with this please? Mariana
Either your fruit is not ripe or your tree has reverted to root stock.
Citrus Trees are often grafted unto the root stock of another citrus cultivator.

I'm living in an arid climate where the summers are dry and extremely hot, with temperatures above 45°C (113°F) daily and above 50°C (122°F) can be almost common and it barely drops below 30°C (86°F) even at night. I have a kumquat tree which is grafted into a kaffir lime rootstock, It's in the fruiting stage and the plant is potted into a 5 gallon pot. The plant is currently inside but it seems to be suffering from the lack of air circulation and sunlight. I was wondering if the plant can handle the excessive heat outside and if I should move it out?
Temperatures above 90 degrees F can adversely effect the health and fruiting of your Citrus Tree.
Since your tree is potted, you can perhaps move it to a more cool location when the temperatures are at their peak.
Adjust the tree slowly to it's outdoor location to avoid stress.
Pay attention to water needs with outdoor containers. They may need to be watered twice a day.

I bought a Sweet Kumquat tree last spring. It is now September in Galveston area and it produced many green fruit. It's been about a month and they never ripened. Should I remove them? Will this hinder the flowers in the spring?
The timing of the fruit ripening depends greatly on the variety that you are growing.

I've had a potted kumquat tree for many years. Just recently the leaves and fruit have been dropping off rapidly. In summer it is on the south side of our home and gets water every 2-3 days because the Oklahoma sun can be brutal. This is the first time we've had any problems with the tree. I suspect it may be root bound, as it's been in its current pot about 4 years. The tree is approximately 5-6 ft tall. Could being root bound cause the leaf/fruit drop or is there another problem I need your help with to identify? Thank you, Alison Anderson
Yes, it very likely needs repotting, as a Kumquat Tree does not like to be root bound.

Do I peel the seeds as with lemon seeds?
Kumquats can be germinated without peeling the seeds. It is possible that peeling them could increase germination, but I'm not sure. You could try an experiment with a few peeled and unpeeled seeds and see what happens!
