My kaffir lime tree (about feet tall) is having yellow leaves. The leaves would change color from light green to yellow. The change is evenly on a leaf. It used to respond positively with chicken manure, but not in the past 3 months. There are other trees around it, the closest one is about 1 foot away. What should I do?
It sounds like you may have Chlorosis. This article will help with that:

I would also just give it a balanced fertilizer. Chicken manure is mostly nitrogen and there may be an imbalance in the soil.
My plant has gone all sticky and looks like lots of sticky strands. It also looks like it may have an infestation.
There are a few pests that can cause this, such as aphids or scale. Fortunately, they can all be treated with a general pesticide.
I will say though, these pests tend to attack trees that are stressed. You may want to check and see if there is anything that may be stressing the tree, such as a lack of nutrients or improper watering.
I have an Amaryllis (Clivia miniata) or Kaffir lily. I have several. One is having roots that are coming up from the stem and growing along the top of the dirt. They are like white, thin fingers. Is this OK? Does the plant need something or is it getting too much of something instead?
It sounds like your plants could be root bound, in which case some repotting is in order. Here is more information: https://www.gardeningknowhow.com/plant-problems/environmental/root-bound-symptoms.htm
I have a kaffir lime plant in a pot which I have had for about 3 years. Every summer it lives outside on my deck (central NJ) and I bring it inside in the winter. It has always been very healthy, producing lots of shiny new leaves and shoots. When I first brought it inside this fall, it dropped a lot of leaves, but has been stable until the last week or so. It is now dropping dozens of leaves each day, and if I gently touch it, lots more fall off. What can I do? Some of the branches are now completely bare. Should I trim them back? I can post a picture if it would be of use.
Leaf drop is usually associated with stress of some kind. It could simply be acclimating to its indoor environment. Also, if you have not fertilized it recently, I would recommend that you do that. Here is more information on fertilizing: https://www.gardeningknowhow.com/edible/fruits/citrus/fertilizing-citrus-trees-best-practices-for-citrus-fertilizing.htm
If you have fertilized, I would recommend that you make sure that you are watering regularly and deeply as leaf drop commonly happens due to watering issues. This article will explain more:

The best thing you can do is just make sure it gets the water it needs. The leaves will grow back. Here is more information:

Kaffir plant winter protection (southern MD, 20745)--7 years old, maybe older.
If you expect frost or freezing weather, make sure that the tree is covered at night (a bedsheet will do) and that that the covering is taken off first thing in the morning. Here is more information: https://www.gardeningknowhow.com/plant-problems/environmental/frost-how-to-protect-your-plants.htm

The leaves on my kaffir lime tree are really sticky and it is dropping sticky goop on the floor. A lot of leaves have fallen off already. I have sprayed it several times with a systemic insecticide which seems to help a little but hasn't cured the problem.
This article has some good information: https://www.gardeningknowhow.com/plant-problems/pests/homemade-aphid-control-a-natural-way-to-kill-aphids.htm
And even though it deals primarily with outside plants, aphids remain the same.
Neem oil works, as does soap and water. Use the neem oil according to package directions. If you use anything that has no residual effects, still use according to package directions, or devery 5-7 days. Soap and water will kill the adults, but the aphids will reappear when the eggs hatch. Make sure you break their life cycle.
I had a kaffir lime plant while living on the West Coast. The plant has since died once we moved to Atlanta. It started shedding leaves last winter, and all the branches are brown with no leaves. I would like to have a plant at home, for Thai cooking. Thanks.
Have you considered phoning greenhouses in the area? If they don't have one, ask if they know anyone who does. Maybe they could get one for you. Sometimes a florist can special order items.
