Question: We have nine pine trees, and they are dropping lots of needles. We have a large berm under the trees and water inside the berm twice weekly. Should the needles be removed or left inside the berm?

Question: In a past posting on your blog, you mentioned that using 100 percent distilled water for container plant irrigation might mess with the potting soil. What did you mean by that?
Question: I planted a five gallon loquat in my front yard three months ago in April. It seemed to be taking just fine at first. A few weeks ago, I noticed the older leaves were beginning to turn brown, and the newer leaves seem to be shriveling up. When I purchased it, I was told it was OK to plant in full sun. During this heat, I drip water it every two days. I estimate it receives about six gallons per watering. I check the soil regularly to make sure the soil is not drying out. Any thoughts?
Question: While preparing my holes to plant my fruit trees, I encountered caliche. I’m able to dig down to about 18 inches by 24 inches across.
