Using sustainable and research-based techniques, learn how to grow your own vegetables, connect with other gardeners, or use Ask an Expert to seek gardening advice. 

Things to do in December

  • Check stored flower bulbs, fresh vegetables, and fruits for rot and fungus problems. Discard any showing signs of rot.

  • Central/Eastern Oregon: Water your plants every 6 to 8 weeks with a deep soaking to prevent drying out.

  • Avoid mounding mulching materials around the bases of trees and shrubs. The mulch might provide cover for rodents.

Question of the Week

I found this growing in my garden and I'm not sure what it is. My girlfriend said it looks Sinister! Can you tell me what this is? My best guess is maybe something to do with dill because I had some dill plants there, but they kind of look like mushrooms or alien eggs. There were also some zucchini plants there.
