How to treat sticky leaves on indoor plants and citron?
Sticky leaves are almost always a sign of infestation by one of 2 or 3 kinds of bugs - aphids, scale, or mealybugs. If you look closely at your plants, you should be able to see the culprits sticking to the undersides of leaves and/or stems. There are several approaches to treatment, but the least invasive is spraying with a soap or soap and neem oil mixture. Be sure to spray weekly for 4 weeks.

I have a citron pot grown for more than 5 years. I let it dry out, but it came back. There is a large "something" that could be a seed pod, or a disease. My husband, who was the plant guru, died in December and I do not know if that large green thing (almost shaped like a citron) is fruit, fungus or who knows? After I began watering it regularly, it produced tiny white flowers. How do I care for it? It lives indoors during the winter and outdoors when it is warm enough. What is warm enough?
The 'something' you describe is a citron fruit.
Continue to water it on a regular schedule. Since the citron is a citrus fruit, you would care for it the same as a citrus tree.

A small citrus tree grows near my son's classroom in Chandler, Arizona. They refer to it as the weird lemon tree, with a super bumpy peel, and more dry inside than a typical lemon that you can juice. They let my son pick one. It is larger than most lemons at the store. We cut it and it is somewhat dry, not for juicing, and has large visible pulp pieces (I don't know proper vocab) within all the sections. What is this fruit?? Could we make something with it to teach the kids how it can be eaten or used in cooking? Thank you!
This is Citron fruit.

I've been growing 2 citron trees for 10-12 years now and on average only achieve fruiting perhaps every 3 years due to spider mite (probably) infestation damage when I bring my beautiful, vibrant summer trees in for the winter. I use external lighting however, it does add a warmer environment to the tree. This year, I will be using COB led lighting which may be cooler and considerably brighter. I've used imidaclorpride soil drenching, topical sprays and my go-to, which worked in the past, Hotshot No-Pest slow release hanging strip (ddvp). Even these, aren't working either and all the leaves wither, fall off the trees, and half the time, the branches die off totally and my trees are reborn via sucker branches. If I can avoid this dies off, the woody branches would then allow the trees to bear fruit since the new suckers are too supple to bear fruit until they woodify. The Hotshot product is not recommended for extended stay with humans in the same room, so I would like to discontinue its use if possible. Perhaps pretreating prior to bringing them inside or different pesticides?? Or anything that may work?? So, perhaps outside and then inside treatments? Help!!! Thanks, Bill nearchemsp@aol.com
We would recommend Neem Oil to treat the Spider Mites.
