Protect your plants from freezing temperatures

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.

Temperature, irrigation troubles can hamper kumquats

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.

Debunking the myths of pine needle mulch

Ash trees not good choice for Southern Nevada climate

Ash trees do not fare well in desert Southwest

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?

Although it’s warm now, cold weather still possible next month

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.

Move plants when temperature permits
