Gumbo Limbo trees in need of help
Hello, We have 6 or 7 gumbo limbos in the yard and a few of them are doing awful. 2 years ago they were quite a sight, but this Winter they lost most leaves and now have lichens growing on most branches... not a good thing. I spoke with an arborist about a year ago on how a few of the gumbos were covered with scale and black mildewy soot. He said the same thing happened to some of his and also to many in the South Florida area. I sprayed the trees and they did better this season as far as bugs go, but over the Summer they started losing leaves again and now the lichen have grown on most branches. Has anyone had this problem? Does anyone know what I could try? What sort of fertilizer, how often etc...? and I'm thinking they may not have received enough water (due to sprinkler system issues) and I'm not sure if that contributed. Please help!
2 and 3 years ago people would always stop and ask what type of trees they were and how beautiful they looked. Not anymore. Thanks. Joss
