Things to do in December

  • Protect new landscape plants from wind. Use stakes, guy wires and/or windbreaks as needed.

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

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

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?
