Haven’t planted your garlic yet? It’s not too late! You can still plant your garlic until your ground has frozen solid.

For those of you who haven’t planted yet, and even for those who have, here is an excellent article from WSU on growing garlic in the home garden! It will walk you through from picking the right garlic to harvest. Here’s to a delicious year!

For home gardeners in the Northwest, garlic (Allium sativum) is easy to grow, prolific, and can be stored for several months after it is harvested in midsummer. This publication offers information on planting, maintenance, pest management, and harvest and storage.
