Hi, i need some advice. Struggling with the same issue and cannot figure out who is eating our meyer lemon tree. The problem is i cannot catch the “offenders” in the act (looked with flashlight in the middle of the night and in early morning). I tried various sprays and nothing seems to work. Not sure if it makes a difference, but we live in the Bay Area in California. Thank you for any advice you can offer.

Mites are from the pit of hell. I had them this past winter on mesemb seedlings and string of dolphins. They literally suck the life right out of them and leave hideous scars behind. They are VERY hard to get rid of so the very best thing to do is like Rina said, get them out of the warm and dry and introduce them to a humid environment for a spell. When you see them (and the webs), you have an infestation and they are most definitely on more plants than just where you see the webs and insects. I typically don't use any product that can potentially harm bees but I had no choice with these. Since I didn't want to spend $200 on Forbid (which IS the best), I went with Bayer 3 in 1 and took everyone outside under the shade cloth into the humidity. Azamax (azadiractin neem derivative) didn't work. I am not 100% certain but I do believe 3 in 1 will remove the farina off of your plants so it may be best to use it as a soil drench vs. spraying on the leaves. From what I understand, the miticide is introduced into the plant via new growth *only* but I could be wrong. Someone with more knowledge can correct me here.

Like the one on the racing car, but you're going to have to insist it wears a helmet and uses the seat belt, can't have them driving irresponsibly, LOL. I've got a photo of one of mine checking out my weather station console. And I always thought they had their own way of forecasting weather. They like getting into hollow pipes for the acoustics. It makes quite a difference, especially if you're trying to get to sleep. The Northern Laughing Frogs (or Roths Tree Frog) are really great. They'll be all through the trees so as you walk through the garden at night they're laughing/cackling away all around and above. I'll email you a sound file of them calling (MP3 file).

Interesting issue.... Based on the clockwise twining seen in your pictures, this appears to be a Japanese wisteria. Is is a named variety/grafted plant? Does it produce a lot of root suckers and, if so, do you allow them to remain and climb on the structure? You said in your original post that the vine is doing well - is any part of it visibly dead - i.e. no leaf or flower growth? Does the vine lose its leaves at some point in the year in your climate? (My two wisterias are just losing their leaves for the winter now....) If the vine loses its leaves at some point in your growing season, that's a good time to give it a close inspection. Since the support structure is also wood, it may well have rot too, so check it carefully (What kind of wood is the support structure?) Wisterias are pretty tough plants that can survive a lot of damage. If it is still producing healthy new growth from the stems that have split, I wouldn't worry too much about the vine. If there are areas where the vine is dead (i.e. no leaf or flower growth) I'd prune out the dead section and let nearby healthy growth fill the blank space. If there are suckers from above a graft union or if you normally let root sucker grow and they flower the same as the rest of the vine, you could use them to help fill in any dead sections too. If there is a nearby botanical garden or a commercial grower of the vines, you could ask them for further help in identifying the source of the problem and what to do. At this point, I wouldn't give up or the vine or assume it will die out. They are very tough plants and it would take a lot of damage to completely kill it! Do you have a picture of it in flower on the structure? If so, I'd love to see it....
