Question: I have a good-sized area covered with rock mulch. A flowering plum tree is struggling in this area. Can a Myer’s lemon tree do well in a rock mulch setting?

Question: My crocuses and tulips are poking their heads out of the dirt in my garden. They’re growing. We have had great spring weather in January. Should I let them continue, or should I put some more dirt on them?
Question: I heard it is best to move rock away from my shrubs and replace it with mulch. What is your recommendation?
Question: I removed a peach tree that had borers. How soon can I plant another peach tree in the same hole?
Question: What do you say is our planting zone? I got a Plant Smart Sensor for Christmas, and it says we are a 7B, which is way lower than I’ve read. Just because a website says a tree or plant will be OK for a certain zone doesn’t mean it is necessarily, right?
Question: When is a good time to plant fruit trees?
Question: I would like to cut back some cassia, Texas ranger and Rosemary plants that have grown too large. When is the best time to do so?
Question: When should I cut my grape vines back? They’re on a trellis and are 1 year old. During the summer, they spread out very well and produced several large groups of table grapes.
Question: I remember you said to apply fertilizer to a lawn around Thanksgiving. But during that time, it was cold, and the fertilizer bag says to water frequently.
Question: I have a Meyer lemon in a container that still has lemons on it. They are not totally ripe. What trimming should be done and what time of year?
Question: I was reading that you really like the Arctic Star nectarine tree for growing here in Las Vegas. Is this tree a dwarf? How big will it get? What do you think of planting fruit trees in the front yard (not as a focal point, but rather on the side of the house)?
Question: I planted an orchard about 4 years ago here in Pahrump. I planted many different fruit varieties and have come to find some of them do not work here. Their blossoms and foliage, in most cases, are very beautiful, but the fruit does not ripen. I was wondering about some other fruit trees that may work in our area.
Question: I have a Washington navel orange which is about four or five years old. The fruit is splitting. What causes this?
Question: In March of this year I planted a 2-foot tree with few leaves. It now has grown to 4 feet with a wide spread of branches. It is planted in an 18-inch pot in the southeast section of my yard. Will this tree continue to grow in a container? If so, should I transplant it to a larger container? I grow citrus trees in containers and in the ground successfully. This is my first attempt to grow a peach tree.
