Title: New nursery plants with sappy spots from Round Rock, TX
Answered by: Barbara Medford

QUESTION:

We live on the west side of RR, near Cedar Park and recently bought three 15 gallon cherry laurels from a nursery. Started to plant them today as we bought them a week ago and noticed base of the trunk from top to bottom is covered in black spots and some look like sap coming out. What is it and how can I save them? There are hundreds of spots on the trunk, I can email a picture. Thanks!

ANSWER:

Honestly, if you still have your charge card receipt or other proof of purchase, we would hotfoot that Prunus caroliniana (Cherry laurel) back to the nursery. That sounds like an insect of some sort, and the loss of sap is a serious threat to the plant. Not only do you not want to spend the time and money planting that plant, you don't want whatever it is spreading to other parts of your garden. In fact, if you don't have proof of purchase, and the nursery won't admit liability, we would recommed leaving the infected plants there anyway, to get them out of your garden.
