I was reading about your use of pheromone traps for insect control in fruit trees. Which traps do you use, and when do you put them out?
Is there a difference between rosemary used for cooking and rosemary used in landscaping?
I have a major borer problem with my nectarine tree. I will be removing it and replanting. Do I need to treat the soil before I plant another tree?
A friend of mine is having trouble with his century plants, agave and cactuses turning yellow in June and July. These plants are in a rock yard with hand watering. They are 2 years old.
We have a critter attacking our lemons. It does not eat the fruit, only the peel. It eats the peel so cleanly that the bare fruit is left hanging on the tree.
We use a white, breathable fabric for some of our tender desert plants when there's a chance of freezing temperatures.
Pomegranate bugs can be defeated
Grape leaf skeletonizers have multiple generations during the growing season and protection from Bt only lasts a few days.
Canary palms are susceptible to a disease called Fusarium that can contaminate the soil in the planting hole and prevent you from planting a new one in that spot.
The best time to transplant a Joshua tree is in mid- to late spring, but with this plant it could be done in summer as well. The worst times are fall and early winter months. Stay away from these months for planting a Joshua.
Fall plants can be started now
Q: I enjoy your column, but you never write about roses. We inherited 14-year-old bushes. The bushes are important, and they should look nice.
Basil, cilantro and Italian parsley are easy to grow here if you prepared your soil adequately and grow them at the right time of year.
Leafhoppers are very small and jump rather than fly. There can be hundreds if not thousands right about now on grapes. They cause some leaf yellowing, black specks on the leaves and fruit.
Question: I want to plant potatoes here in Las Vegas. Our season is timed different than others, though, so there aren't seed potatoes available now for a mid- or late July planting.
Q: I read with interest your column in the Review-Journal on watering. Our small lawn seems to be dying in patches. We water four days a week for 20 minutes at 11 p.m. We regularly feed with Turf Builder Plus and Ironite. What should we do?
Q: I took your advice and am treating pill bugs in my garden like slugs. I have drowned them with beer but they keep coming back. My neighbor is giving me his old cans of beer. I had to dig up the rhubarb plants and put them in pots. This is sure a frustrating year.
The freeze is coming. Remember that the coldest is just before dawn. Clear, cloudless skies are more likely to give us lower temperatures and freezing; windy cold is worse than just cold. Cover tender plants before you go to bed and uncover them when it is no longer freezing.
Q: This last year we have had very little fruit on our kumquat, although the tree had been ample with fruit before. The tree appears to be healthy, just no fruit. The only difference I can think of is that in previous years I covered the tree whenever the temperature was below freezing.
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.
Question: Would you please tell me what type of mulch is not recommended to put in flower beds? I thought I remembered it being redwood mulch, but I can’t find anything on that. Could it have been cedar? My landscape guy says the shredded cedar is not a problem for vegetation.
Question: What is your favorite apricot to grow in Las Vegas?
