Keeping kiwis protected paramount to success

Question: I recently purchased male and female Hardy Kiwi starts form Parks Seed Company. I was wondering if you might be able to give me any tips for growing them here in the Las Vegas Valley. I have done some reading on pruning and training them into a trunk and building a T-trellis. In what I have read, they need full sunlight, but I am of the mind that perhaps afternoon shade might be a bit better.

Texas laurel a persnickety plant

Question: My Texas mountain laurel has yellow leaves, and they continue to get more yellow as time goes by. It faces southwest, has two adjustable emitters turned down low, watering once a week for one hour in the winter.

Sapsucker damage is impossible to prevent

Question: Can you tell what is damaging my 7-year-old blue ghost tree? This damage is about 12 feet high on the north side, and there is a line of holes in the trunk.

Fruit trees prefer wood mulch to rock
BOB MORRIS

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?

Warm midwinter weather confusing to bulbs
BOB MORRIS

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?

Mulch of any type important to all plants
BOB MORRIS

Question: I heard it is best to move rock away from my shrubs and replace it with mulch. What is your recommendation?

Microclimates, manual control affect planting
BOB MORRIS

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?

Flower bloom determines pruning time
BOB MORRIS

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?

Grapes need patience when it comes to pruning
BOB MORRIS

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.

Fertilizing now will keep lawn lovely
BOB MORRIS

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.

Culling citrus key to a healthy tree
BOB MORRIS

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?

Arctic Star fruit tree works for focal points
BOB MORRIS

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)?
