The most frequently asked question asked in 2016 concerned fig trees. Readers wanted to know why their fig trees did not produce good fruit. Either the fruit dropped from the tree when it was small, or the fruit clung to the tree and never became large but remained small, hard and dry.

Q: It got to 30 degrees overnight in Boulder City. I’m worried about my little 6-foot lemon tree in a 5-gallon pot on the porch. I placed a queen-size bed sheet over the tree and hung a 100-watt incandescent lamp from a branch last night. I’m hoping that small amount of heat will raise the temperatures above freezing. Is this necessary?
Temperatures turned cold this past week. Historically, we still have about three or four more weeks of warm weather so it probably will get warm again soon. But if you plant vegetables from seed, these cold soil temperatures should still be warm enough to germinate radish, peas, beets, possibly carrots and turnips.
Fall and early winter are excellent times to prevent insect problems that occur next year. I received reports of worms or grubs feeding now on the roots of plants. The most common are white grubs.
Reading some of the national gardening blogs and articles gives me a chuckle. Frequently they are out of touch with gardening and horticulture in the desert Southwest. For instance, one recently said there was little to do during the winter months. Obviously, they have never lived in our climate.
Q: I found 50 to 100 red and black beetles running around the rocks in my yard while I was pulling weeds. If these numbers are representative, I must have thousands. A friend thinks they may be boxelder bugs, but I don’t have any boxelder trees in my yard. The pictures of boxelder bugs online are similar but do not look exactly like these. So what are they and should I declare war on them and begin spraying?
Q: About 1/3 of my fruit trees are dying. Some of the branches on a sick tree look healthy; some of the branches on the same tree look dead. There is sap coming from some of the trees. I fear it is a borer infestation. I am scraping the bark and spraying with Neem oil. What do you think?
Q: I have a young, fruiting mulberry and realized too late that it’s planted too close to a wall. When would you recommend is the best time to dig it up and transplant?
