Things To Do: October 2022

In your garden

  • It’s fall, so you can plant, plant, plant!
    • You can plant all kinds of perennials like penstemon, globe mallow, salvias and the like.
    • This time of the year is the best time to plant trees — native and non-native.
    • Get ready for fall planting in your veggie garden.
    • If you want to grow bulbs such as narcissus, tulips, lilies, iris and amaryllis, you can plant them now. If you’re already growing iris, now’s the time to divide them.
  • New plantings can follow this watering schedule from the Pima County Master Gardeners for newly planted native and desert adapted plants:
    • Weeks 1-2 every three to four days;
    • Weeks 3-4 every six to seven days;
    • Weeks 5-6, every seven to 10 days;
    • Weeks 7-8, every 10-14 days.
    • After week 8 gradually extend the time between irrigations until plants are established.
  • You can replenish compost on your plants. If you don’t know how to make your own compost, it can be purchased at Tank’s Green Stuff. You can also use vermicompost, or worm castings, for extra nutrition.
  • You can prune your Texas Rangers after our rains have stopped — they won’t bloom again until next year. Alternatively, you can wait until February or so.
