A: Don’t give up! Fig trees in my neighborhood have lost all their leaves, but scratching the bark with my thumbnail reveals that they are alive. Wait till next May; if you have no leaves then, your fig is dead.

Q: We have blueberry bushes with lots of holes in the leaves. I’ve used systemic insecticide granules on other plants, but since we eat the blueberries, I’m assuming I should not use this product but use something like organic spinosad instead? Tom Pinotti, Decatur

A: You are right, systemic insecticide granules are not labeled for use on edible plants. Since some foliage-damaging beetles feed at night, spray the blueberries at dusk, making sure the spinosad hits the underside of leaves. Repeat every four weeks.

Q: I have an organic vegetable garden and am trying to find organically grown and processed wheat straw for coverage over my winter cover crop seeds. C. Pozzo, email

A: I don’t think there is such a thing as organically grown wheat straw for sale. It would be normal practice to spray herbicides on wheat fields to control weeds. The straw that is collected after harvest, which is then baled and sent for sale at nurseries, has to be processed at a large scale in order to make a profit. You might find organically grown wheat, but it would be a losing proposition for someone other than you to collect and sell the organic straw. Consider just hand-picking weeds until your cover crop spreads and takes over.
