Question:
I have recently moved into my new home, the previously owner had the front landscaped beautifully. In June our 7-10 feet Magnolia tree had a lot of fly and bees and moths around it. As I looked closely I noticed that Magnolia's branches are covered with white oval spot. I have treated with some insect spray twice with no effect. Any suggestions?
Answer:
Thanks for writing. The presence of flies, bees and moths in your new garden is a great sign as they are helpful and necessary pollinators. You do not want to do anything to deter or remove them as they are helping to promote the flowering of your perennials and flowering trees and shrubs. As for the magnolia, I am intrigued. I know some species of Magnolias that have white oval spots that are a natural part of the bark and how it looks and grows. Depending on the size of the spots I wonder if you are looking at lenticels, slightly raised growths on branches that help trees like magnolias and cherries with gas exchange. Next time you inspect the tree see if the spots are uniform throughout the entire tree on branches of the same size. Larger branches will have a different look to the bark as they mature and age. If you find that the oval spots are uniformly all over the tree and the tree appears to be healthy then I am sure there is nothing to worry about. As I say, it might just be the natural characteristic of young magnolia bark. If the oval spots are just on a few branches and you are certain they look different than the rest of the tree then either follow up with me again and describe them as much as you can and/or feel free to send a digital photograph if that is an option as that might help a lot.

Companion Panting in NYC Community Gardens
Question:
I am a new community gardener in New York City. I will be planting vegetables , and I wanted to know are there any companion plants I could include in my garden plot in order to keep pest(insects) away from my vegetables?
Answer:
That is an excellent question! For those of you that do not know, companion planting is a proper horticultural practice that can be a natural preventative step to fend off various pest and disease issues that can affect a vegetable garden. With the right diversity of plants and proper care you can grow a large and healthy crop without having to rely on using strong chemicals. Of course weeding and scouting for pests is still something you have to do in a garden through summer, but knowing a few reliable combinations can be really invaluable. At this moment I must admit that we do not have an updated companion planting list on hand but here at the HSNY Library we have a tremendous selection of books that would be of great assistance for your vegetable gardening efforts. In particular, Katherine Powis, HSNY Librarian, found these titles for you:

The top two books I have used a lot and really enjoy. The others I do not know so well but I am sure they will have things to add. You are always welcome to come to the HSNY Library to read through any of these titles and discuss your vegetable garden with me if I am around. We are open 10-6 Monday through Friday and Katherine is typically here Monday through Thursday. Anyone is invited in to read and research in the library, and to borrow the books we just have to sign you up as an HSNY Member, but that takes no time. Hope this helps. Also, if you have specific pest issues or questions as the season progresses you can feel free to ask me those as well as entomology was part of my horticultural training.
