Pine needles benefit alkaline soil

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?

Distilled water can deflocculate soil

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?

Sensitive loquat requires sun protection

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?

Smaller fruit trees can deal with caliche

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.
