Things to do in December

  • Monitor houseplants for adequate water and fertilizer. Water and fertilizer requirements generally are less in winter.

  • 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.

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?
