I have 2 crabapple trees in my front yard. A few years back we had them sprayed so they would not produce fruit because we hated the mess the crabapples made. A year later we had them sprayed again. The next year they did not produce fruit but all their leaves fell off very early in the summer. A tree service sprayed again for some tree disease. Now the trees do not produce fruit but still loose their leaves very early in the summer and by the end of summer they look like it is the dead of winter. They are unsightly and I am ready to cut them down. I have read on this forum other people using crabapple wood to smoke but just wanted opinions on if the chemicals would be an issue. Keep in mind the spraying happened over a span of a couple years starting 5 yrs ago until about 3 years ago. Any thoughts???
