January 23, 2011Q.Yellow Leaves and Black Spots
My poor yuccas looks 'yucky' right now, and I sure hope I'm not losing them. There have yellowing leaves with lots of black spots. Also, my Rosemary bushes have lots of dying limbs right in the center (the rest of the bushes look healthy). One more thing, my Mountain Laurel trees have started yellowing too. I know they have not been overwatered. When they were healthier, the leaves were a beautiful forest green. They are not full grown, just about 2 feet tall right now.

Certified ExpertA.I would start by getting your soil tested. You sound like you may have a yard wide nitrogen deficiency or an iron deficiency. The soil in the container that they were planted in when you bought them has probably kept them healthy up until now, but now that this has been depleted, the natural soil of your yard cannot support them. If they have been planted for a while, too much rain may have washed away the nutrients. Some fertilizer, regardless, cannot hurt.
Check the undersides or the leaves of the plants for pests as well. Most pests that might possibly cause this kind of damage hide on the bottom of leaves.

August 14, 2012Q.Id Wildflower
Recently I was on Blue Ridge Parkway. Got out at non-descript overlook to stretch my legs and was intoxicated by a heavenly perfume. It was a ball of pinkish flowers in a tightly bound head (much like allium). We photographed it and lingered for as long as possible breathing in the fragrance. Lots of bees were present. Elevation was 4, 000 ft. I want to grow this flower by my porch. Can I get seeds for wildflowers? And will they grow at different elevations? Also, my yard has spruces and is shady but I am willing to do containers and move them around - that is how delicious the experience was.

Certified ExpertA.I think you may have encountered a mountain laurel shrub, which grow extensively in those parts. They share similar growing conditions as that of rhododendrons and are easy to care for. While they grow wild in many areas, there are several cultivars available to the home gardener.

The holly and yews, you can cut back quite severely, but realize that a severe pruning will take about 2 years to fill back in.

Certified ExpertA.When determining whether a plant is appropriate for a certain region we must take into account both the cold tolerance and heat tolerance of the plant. Mountain laurel is designated for USDA plant hardiness zone 5 through 9. South Mississippi is zone 8. So that checks out. And, depending on your location in south mississippi, your AHS heat zone is either 8 or 9. Mountain Laurel's AHS heat zone rating is in the ballpark of 8 or 9 for its threshold. Based on this information, I think they will grow in your area.
This article will give you information to get started with your mountain laurel planting:

I have several mountain laurels that lose their leaves in the spring with leaf spot. New growth appears and the bushes seem healthy, but no flowers or very few. I live in a community not far from the water. These bushes are quite old. Any suggestions? Thank you.

June 12, 2015Q.when to plant mountain laurel
Native mountain laurel where we live (central PA) is in the midst of blooming right now. I would like to purchase some shrubs and use them to landscape our new home in the woods. Is it too late to do this this year? Is fall a better time for planting (even though our winter was exceptionally cold last year)? Would they do best if I wait for spring and plant before they bloom?

June 13, 2015A.You should be able to purchase plants at a local nursery and you could plant now or wait until fall.
