A pest identified in December in Lancaster County, PA may be headed our way.

Called the allium leafminer, it likes leeks, onions, garlic, chives, shallots and green onions. It is not known how the allium leafminer may affect ornamental species.

You can read more about its habits, how it damages plants and what steps you can take to manage the allium leafminer in this article in the newest edition of WNY Gardening Matters, the monthly publication produced by the Cornell Cooperative Extension Master Gardeners in Erie County.

Also in this issue, you can find out how street lights and other artificial illumination can affect trees and what you should do in your garden in July.

    Never heard of this. Good to know.

    Many of the pests that I’ve written about lately bother plants that I don’t have, which is lucky for me. Unfortunately, I grow a lot of garlic so I really hope this pest passes us by.
