Spray grapevines to control pests

Grapeleaf skeletonizer and grape flea beetle were found in the orchard during the last couple of days. These two pests damage grape leaves but few other plants.

Removing dead fronds doesn’t affect health of sago

Q: The top ring of sago palmfronds died after I transplanted it but remain on the plant. I left this brown ring of fronds around the crown of the plant and it looks like new growth coming from the center is OK. Should I trim off the dead fronds without disturbing the crown or just let them fall off?

Yellow leaves not necessarily caused by fertilizer

Q: I see many times where you’ve said fruit trees only need feeding in the spring. However, without periodic applications of nitrogen, my 3-year-old peach tree leaves become yellow. Could there something going on I should investigate?

Waxleaf privet should have more than one drip emitter

Q: I purchased a few waxleaf privet plants in February. They were planted in my yard using drip irrigation with one drip emitter per plant for about one month now. I am starting to see some black markings and yellowing on the leaves. I also think there may be some root rot, but I am unsure.

Removing excess fruit allows remaining fruit to grow larger

If you have fruit trees, the next big tree management activity you are facing is fruit thinning or removing excessive amounts of fruit so that the remaining fruit gets larger. Peaches, nectarines, plums, apples and pears must have excessive fruit removed if you want larger fruit. Do this as soon as the fruit reaches the size of your thumbnail.

Want to see Lake Mead flowers? It’s now or next year

For much of March, a light blanket of what looked like green felt covered hills and rocky fields along Lakeshore Road, where bright yellow brittlebush thrives. Very recently, Lakeshore’s abundant beavertail cactuses started their fuchsia bloom, and they should continue to dazzle for the next couple of weeks.

Proper pruning, thinning, irrigation increases fruit size

Q: Peaches from my dwarf peach tree were very small again last year. This is the third year the fruit developed into a small size. We fertilize them twice a year with vegetable spikes and our in-ground system fertilizer system has Dr. Benson’s Natural Mix added five times per year. Any suggestions?
