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, etc.
    • This time of year is the best time to plant trees – both native and non-native.
    • Get ready for fall planting in your vegetable garden!
    • If you want to grow bulbs like daffodils, tulips, lilies, irises and amaryllis, you can plant them now. If you are already growing irises, now is the time to divide them.
  • New plantings can follow this watering schedule from Pima County Master Gardeners for newly planted native and desert-adapted plants:
    • 1-2 weeks every 3-4 days;
    • 3 -4 weeks every 6-7 days,
    • 5-6 weeks, every 7-10 days,
    • 7-8 weeks, every 10-14 days.
    • After week 8, gradually extend the time between irrigations until plants are established.
