Q: I attached a couple of pictures of my peach tree. It’s growing like gangbusters (I did a pretty good job pruning it back after your class), but something is going on with it because it’s dropping leaves and has this brown-leaf-edges thing going on. It had major growth (about 3 feet) after I harvested the peaches this month. Thank you for any help you can give.
Question: What should I be doing for my lawn in March?
Question: What other landscape shrubs benefit from an application of iron chelate? I know bottlebrush and photinia. Others?
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.
Question: Help! My Italian cypress are drying out and dying mostly from the top down. They have their own bubblers for water.
Question: Following your advice, I am planning to replace all of the stone mulch under and around the shrubs in my yard and use bark mulch, which attracts roaches, I am told.
