Lime tree leaves turning yellow and dropping.

5 years ago

Ive had this lime tree for about 2 years. im not sure what the issue is. last month the leaves began to turn yellow. once i noticed it, i hit it with some citrus fertilizer but it didnt help. i water it as need depending on how the soild feels. so i dont think its water related. i really have no idea what is going on, my poor tree looks terrible. i live in central nj and keep the plant in our sun room. the first two photos were taken a week apart a month ago . and the last photo was taken today. any advice would be greatly appreciated

    can you put it outside. It is not getting enough light.

    How cold has the room where it lives gotten? Have you noticed any bugs? When was the last time you repotted the tree?

  • 5 years ago

    right now it gets pretty warm in our sun room. stays around 65/70 at night and can get up to mid to high 80’s. sometimes 90’s when its really hot out. i looked long and hard to find bugs. there are small spider webs but no spiders. i even used my 1000x magnifier on some leaves and couldnt find anything moving. its been in that pot for about 2 years. i will pull it out tonight and check out the roots .

    You said it's a sun room? Out of curiosity, how cold did the room get this last winter? And spider webs, are you saying thin, longer webs between branches of the kind that would have a hexagonal pattern? Or are you saying thin webbing on the surface of leaves and around the axils?

    Maybe the lowest was probably 55° but wasnt very often & just random small webs, not in pattern form. heres a photo

    That is spider

    Mites

    Most likely every plant in your sun room has them and it's going to be difficult to get rid of. Start spraying with horticultural oil.

    Ken, I was just about to say the same.


    Nikki, if you have webs that have thin threads between larger branches and a hexagonal pattern, it is usually a spider that's set up shop, and it's nothing to worry about (spiders usually try to find big gaps between branches where insects would fly through to trap them, so webs built in that way are usually spiders). When it is around branches and around leaf axils, it is spider mites and you want to deal with that as they can completely defoliate a tree if the infestation is bad enough.

    Oh wow, i really didnt think it was that . i will spray tonight with neem oil. what are the chances of survival?

  • 5 years ago

    Chances of survival are pretty good if you get rid of the mites. How many plants are in your sun room? They will all need to be sprayed. Can you take the citrus outside for the summer?

    Thankfully i had moved all 10 of my fig trees outside right before the lime tree started to turn yellow & they are thriving . of course this would happen to my only citrus tree! right now i have 2 aloe plants in there that i dont see any webs on. i sprayed and put the lime tree outside. fingers cross! thank you everyone for your help !

    And that tree contracted those mites in the first places for good reason. Either your mix is just too moist and compacted along with decayed to allow any roots to get sufficient oxygen properly and or nutrients, that does not allow all the salt deposits to run out from the pot. . Too much root damage causes the tree to look like a desert to mites and any other pests.

    Did you see fungus gnats at all in the winter or even now?

    I would re pot that tree asap with a fresh open mix and water it in well.

    As they say it is better to prevent an issue before it even crops up)


    You said Aloe? Oh they can get mites and hide in places you would never think of. But when you spray them I would not use neem since that can be harsh and burn most succulents. Use a good horticultural oil that is much lighter and that cause less damage. Or you can soak those plants under soapy water for 15 minutes. Them and the eggs will drown.

    Mike, I would second soaking the plants the oil is too harsh for, or if the infestation is too bad. You don't need a lot of soap, just a drop for a large tub. I would also say that it isn't always cultural, sometimes it is environmental. Definitely worth checking the mix, but if the plant was directly on the ground and there were a lot of mites, the plant can be overrun. (Where I live they are everywhere, all of the large trees are covered in webs and damage if you look close, if you put a plant outside on the ground it'll be eaten extremely fast. One of our neighbors just released a predatory mite in their yard to try to get some of the population down.) Sometimes it just pays to know what to look for and try to avoid placing your indoor plants under or around anywhere they're really active.

    Bonsai, true that. That is just horrible having to see that outside. Too bad there was not more useful pests than those. Crazy. Fortunately her tree has been inside this time whole in the sun room and just might of caught them from other plants. In fact, even with open windows. But one thing I do know, it all starts with the health of the plant. Weakened plants always attract the worst predator's. Sort of that final death sentence unless we are aware of it. Thank God someone pointed it out.

    Mike, I agree. Luckily around here, most of the trees are big and old, so you don't notice the damage and the webbing until you get close, and then it's not the whole tree. Plus we have a lot of natural greenery, so they can't possibly destroy it all. But a lot of new neighbors show up, try to grow gardens, and then have to contend with the pests. It may not bug the big trees, but little garden starts or young plants are toast unless you recognize them. Personally I've found that healthier plants can usually withstand them longer, and stand up better to treatment. If her tree wasn't in contact with the other plants, it's possible that the mites didn't spread. I must say, they're my least favorite pest.
