Q.Will datura poison a garlic bed?
We have Datura plants growing heavily in a bed where garlic was harvested in July. Since mid-July they’ve grown to 3 ft. tall. We are going to pull them up…will they leave any compounds in the soil to harm next year’s garlic?

It might. I found a publication from Purdue that said studies show alkaloids from datura plants were harmful to crops. Allelopathic effects had been reported.
