We moved into our place about 8 months ago, and we have a few trees in the backyard- orange, lime and fig. Only the fig produces. The orange is full and green, but the lime is small and stunted. The other day we noticed white webbing containing small eggs covering many of the leaves. The leaves don't show and damage or nibble marks.

1) Any ideas on bugs I should research for San Diego citrus?
2) Am I best to just cut off the leaves and dispose of it, or is treatment necessary (would definitely want an organic solution)? We mainly want to protect the fig tree.

Thanks

In the meantime, if what you mean by webbing is something resembling a beard, take a look at the info about giant whitefly.

Beyond that, San Diego is a hotbed for citrus problems.
