September Gardening Checklist

Summer slowly turns to fall in Southern California, and it’s a very busy time in the garden. It tends to be helpful for gardeners to have a gardening checklist. It’s a time for sprucing up and planning for next spring. Generally, trees and shrubs need to be watered less (which is great for a drought-stricken California). September is a time to keep after weeds and pests (like the slugs)… And it’s time to purchase, prune, and fertilize.

According to Hidden Hills Garden Designer and resident Linda McKendry and her blog at, here is a gardening checklist for September.

Plant/Purchase Garden Checklist


  • Begin purchasing spring-flowering bulbs
  • Start planting bulbs, especially drought-resistance ones
  • Plant bulb covers over spring flowering bulbs
  • Start planting cool-season flowers to bloom during spring or winter
  • Plant Sweet peas from seeds for Christmas bloom
  • Start planting winter vegetables



  • Divide irises that need division
  • Start disbudding camellias
  • Deadhead roses
  • Start fall cleanup for perennials
  • Remove faded and ratty flowers from warm season ornamental grasses

Fertilize/Feed Fuchsias


  • Feed all container-grown succulents with a well-diluted complete liquid fertilizer
  • To maintain the color of blue hydrangeas, start treating the soil with aluminum sulfate
  • Fertilize azaleas at month’s end for the second and last time of the year
  • Fertilize roses.
