So far this spring i have lost: 3ft higasa yama, koto no ito 2ft shin chishio, shishigashira, peaches and cream, mikawa yatsubusa 1ft Jerre Schwartz, fairy hair, hupps dwarf plus at least 67 4-inch new grafts. These leafed out (just long enough for me to fall in love in with them) then wilted and died. What am i doing wrong!! i'm about to give up on my maple hobby. I'm guessing i'm losing these to some kind of root rot or psuedomonas or botrytis. My maples look healthy during the fall and winter then spring time comes and either the buds turn black or i see black patches on the bark (usually at the base or at the graft union. the trees then wilt and die.
