I have a problem, long story made short, killed two young Apple trees last year. Want to replace them this year, but don't want to kill these new ones.
Came to test the Ph only to find it up to 7.8, far too high for apples.
I have read about sulphuric acid to lower it for blueberries. Would this be acceptable for apples? Sulphur maybe? How about my other trees?
Any help would be appreciate.
