I HAVE ROUND GREEN NODULES GROWING ON THE UNDERSIDE OF THE LEAVES OF MY HACKBERRY TREE. WHATEVER IT IS, IT STARTED ON ANOTHER TREE BUT I HAD THAT TREE REMOVED (FOR A REASON THAT HAD NOTHING TO DO WITHE THE NODULES). HOWEVER, THE NODULES HAVE NOW SPREAD TO A VERY THIS VERY OLD, VERY TALL HACKBERRY TREE. I AM WORRIED IT WILL SPREAD TO ALL OF THE TREES IN OUR BLOCK (THERE ARE LOTS) IF I DO NOT DO SOMETHING ABOUT IT. ALSO, IN THE FALL I WOULD LIKE TO ADD THE LEAVES TO MY COMPOST BIN BUT AM AFRAID THE NODULES WILL RUIN NEXT YEARS GARDEN. I DO NOT THINK SPRAYING IS AN OPTION WITHOUT GOING TO GREAT EXPENSE AS THE TREE IF VERY TALL.
ANY SUGGESTIONS ON WHAT IT IS AND HOW TO GET RID OF IT WILL BE APPRECIATED.
