General Garden Care
- Prepare for cold weather—drain irrigation lines, prepare frames for cold sensitive plants, irrigate plants if cold temperatures are anticipated and it has not rained recently.
- Mow lawns, add a thin layer of compost if needed. Consider replacing lawns with less resource intensive (and labor intensive) plants.
- Rake leaves and shed as mulch or compost.
- Cover the compost pile(s) to keep them warmer and to minimize leaching.
- Remove winter weeds while small.
- Trap or bait for snails and slugs. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7427.html.
- Check your garden for empty pots, etc., that can hold water and provide a habitat for mosquitoes.
