Things to do in December

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

  • Yard sanitation: rake leaves, cut and remove withered stalks of perennial flowers, mulch flowerbeds, and hoe or pull winter weeds.

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

Question of the Week

I'd like to mix more sand into my soil to help break up the clay. If I collect sand from an ocean beach, should I be worried about too much salt in the sand and it impacting my soil? If I were to use the beach sand for another project like a base for setting paving stones, would I be introducing a large amount of sodium?
