Soil Preparation
  • Check for drainage – if drainage is poor, now is the time to fix it.

  • Dig a test hole 12” deep, fill it with water and let it drain overnight.

  • The next day, fill the hole with water again and see how many inches of water drain in an hour. Well-draining soil drains at a rate of 1-3 inches per hour.

  • If drainage is poor, cultivate in composted organic material to improve conditions.

  • Correct major drainage problems with a drain system, but never send the drainage to the gutter.

  • Cultivate in soil amendments to at least 12” deep if you have poor soil fertility or structure (clay, rocky, hard).

  • Consider purchasing topsoil to improve soil conditions for the long term. Cultivate it in to a depth of at least 6”; don’t just spread it on top.

  • Grade your site to drain away from foundations and away from the curb. Runoff from irrigation or rain should drain to a catchment area where it can filter back into the ground
