Q: We have 14-year-old pine trees with large water berms under them for collecting water. The inside of these berms are full of pine needles that I hoped would help hold moisture but they do not deteriorate. Should they be left under the trees or be removed?
Q: I am having trouble finding a tree to replace ash trees. I want something that doesn’t grow so tall and does well in our climate. We took out our ash trees because they were giant and the roots were all at the surface. I am now guessing we have a soil issue. True?
Q: I have two 20-year-old ash trees that appear to be dying. I have attached pictures. The smaller tree is a Modesto ash and it started losing limbs about a year ago. The bark is now separating and it looks like an old stump with a few sprouts. The other is a Rayburn ash. Its limbs started dying this summer, but the limb deaths are accelerating.
Q: Last week we planted several fruit trees and have established trees as well. Would you recommend applying fertilizer around these trees now? Spikes or granular type of fertilizer?
This has not been unusual weather. It’s the norm. But watch out! February can be dangerous for plants. December 1990 was one of the coldest months on record, but February 1989 was much more damaging to plants.
For those who would like quality roses, Plant World Nursery on West Charleston Boulevard has brought in Weeks roses. These are high quality roses. They will cost more than roses produced for mass merchandisers but they are high quality. For a recommended rose for the desert, visit my blog and search for “best roses for the desert.”
Q. Are these nematodes on my tomato roots in the picture I sent to you?
Reports from the weather station at the University of Nevada Cooperative Extension orchard in North Las Vegas put the low temperatures Dec. 6 and 10 at 20 F with daytime highs around the same as the inside of a refrigerator. I am sure this caused some damage to plants. I posted the weather report on my blog for those interested.
Q. I am interested in raising dragon fruit. Any suggestions or comments?
Q: I have a pomegranate plant that I started two years ago. It is about four feet tall now, and looks like it wants to be a bush.
Q . Before the first freeze in Las Vegas what should I feed my bougainvillea? I have three plants, all in the ground. They are 6 years old and I wrap their bases before the freeze. They always come back come March and bloom beautifully August through October.
Q: Is it too cold to dethatch my Bermuda grass lawn? Do I have to wait until next year? What about overseeding? Is it also too late? If I need to wait, then when?
Q: I planted a pomegranate tree two years ago and this year it produced six fruits. One was of decent size while the others were on the small side. When the large one split, I picked it only to find the inside was light pink. The seeds were well-developed but not the expected red color.
Q: I heard about a cherry tree from the Dave Wilson Nursery website that has very low chill hours. Can we order these from the University of Nevada Cooperative Extension Master Gardener Orchard?
Q: We have an Elberta peach that we harvest in August and the fruit is always small and on the mushy side. Are there better peaches we can grow?
As I promised, here is an abbreviated version of the problem and solutions to rabbit vandalism in residential landscapes.
Q: I planted six Podocarpus in March, three by the north wall and three by the south wall. Now the three on the north wall have leaves that are turning brown. The three on the south wall are fine. I didn’t realize that the trees would get this much sunscald. Any suggestions on what I can do, besides give them macronutrients and hope for the sun to change course?
