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: I have two Santa Rosa plum trees planted in my backyard. One is planted in a lawn, and the other is in a rock landscape. Both are doing well with numerous large plums growing on them. The one in the lawn area has about 25 percent small yellow plums that fall off when I flick them or shake the branches. The remainder of the larger plums look great.
Question: I have a recently planted ocotillo. It is tied together by wire. When should I cut the ties? Also, I heard that I should spray the plant with water frequently. What’s frequently?
Question: I’m replacing my red yuccas that have grown too large for a 3-foot area. They are in full sun. They spill over into the walkway where my grandchildren have been getting stabbed by the leaves. Can tree roses handle that location?

Question: I live in a third-floor condo that faces south. I get about seven hours of direct sun and have containers on my patio with spinach, tomatoes and peppers that are doing well so far. I was wondering if there are any types of fruit trees that produce and thrive in a patio container.
Question: We have a 20-year-old olive tree in our front yard diagnosed with verticillium wilt disease. The north third of the tree appears to be healthy. If we remove this tree, what distance from the old hole is needed for the new tree? We would like a replacement tree to provide shade. We are looking at oak, pine, ash, spruce or fir.

Question: On the north side of our house, we have a 10-foot-wide space we are trying to landscape. Several have suggested planting bay laurel trees, but we are concerned about the tree’s size for the space. When we went to the nursery, their suggestion was the Majestic Beauty hawthorn tree. Will the hawthorn tree do well in our climate and soils?

Question: I purchased a lovely Meyer Lemon tree in a 1-gallon pot in the middle of the spring. It already had six lemons on it. I have the original fruit, have new fruit growing and still am getting blossoms. Should I transplant it now into a larger pot or wait until after the fruit ripens and is used?
Question: What should we be doing to our fruit trees right now?
Question: I have planter boxes that get hours of direct sun. I’ve tried everything from corn to edamame, grapes, peppers, tomatillo and many others. I have even put up shading, but either there is too much sun or maybe I overwater. I’d like to start now and get a jump on summer.
Question: When do I no longer have to protect my citrus plants from freezing weather?
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.

Question: Can I start feeding my fruit trees now, or should I wait until spring?

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.”

Question: During the excessive hot spell in July, our irrigation failed while we were out of town. As a result, one of our queen palms lost all of its branches. In spite of subsequent life support, it does not appear to be coming back. Is that too much to hope for? Is there anything we can do to help it recover, or should we just mourn its passing?
