What kind of wood did you use to construct the 4 X 4 beds with ??
Did you use treated (Preservative )wood ?
#1)The yellow/green wood is Copper sulfate treated.
#2)The Black coated wood is creosote treated wood
Both are toxic to plants, as the preservative will leech into the soil.
The only corrective treatment is to line each of your planting beds with plastic film to prevent leaching, and re-plant.
Choose those plants that are recommended by your local cooperative extension office for your geographic area .
I used untreated wood. Didn’t paint it or stain it.
Think it might be the heat. Had beautiful plants, just no fruit. I used Mel’s mix so I didn’t understand about phosphorous, other fertilizer. Wasn’t needed according to the book.
Now that it is cooler, going to try again this weekend. What would be good for the fall?
