“I’m so glad I live in a world where there are Octobers.”
— L.M. Montgomery


Living in the low desert of Arizona year-round means intense dry heat in June and July. This is followed by more heat, windstorms, and monsoons in August and September. At the end of the summer, you are ready for the cooler mornings and pleasant (albeit a little warm) days of October.

Certainly, October in the Arizona garden is a busy time. Fortunately, the cooler temperatures are a welcome relief and it’s a pleasure to be outside after the heat of the summer. 

Keep reading for garden inspiration, an October garden checklist, and a list of what vegetables, herbs, and flowers to plant in your Arizona garden in October.

October in the Arizona garden is harvest time for peppers. If you gave them a light prune in September, you can expect new growth and healthy peppers to harvest. Give pepper plants a weekly foliar spray of epsom salt while they are actively growing.

Peas are a family favorite straight from the garden. Plant peas this month and continue to plant them through February. Peas planted in October or earlier in September will mature more quickly than those planted later in the year (the cooler temps will slow them down a bit).

It’s finally (hopefully) cool enough to plant all the winter greens we’ve been craving all summer. Pay attention to the temperatures and don’t plant them too soon, or they will bolt. Plant several varieties in your garden.

October in Arizona is the perfect time to plant wildflowers. Spread seeds in the rocky areas of your yard. The wildflower seeds will germinate with October’s cooler temperatures and rain. Wildflowers provide color and visual interest in your yard until temperatures heat up in the spring. Let seeds drop if you want the wildflowers to come back each year.

Peach trees and other deciduous fruit trees‘ leaves are beginning to change color in preparation for losing their leaves. Be sure to clean up around trees, and remove any fallen fruit to prevent pests from overwintering near your trees. Consider planting garlic in your tree wells to deter pests as well.

The citrus in your yard should be looking happy this month. If you didn’t fertilize your trees last month, do it at the beginning of the month. Hopefully, you are seeing new growth being pushed out and lots of fruit ripening on the trees. If your tree is not looking good, evaluate what went wrong this summer. It’s important to make sure you have the right tree in the right spot with the correct watering in your yard.

everything I try to start from seed gets eaten, any tips on how to prevent this?

Angela Judd

Wednesday 14th of October 2020

I have this happen to me in several of my beds as well. If birds are the issue, cover the seedlings/seeds with tulle or netting. If rollie-pollie type bugs are the issue that's tougher. In my beds where that is a bad issue I do a few different things 1. plant larger seedlings 2. plant seeds that they don't like 3. trap the bugs with yeast or citrus traps 4. Use newspaper collars or other barrier type methods. This article may help as well: https://growinginthegarden.com/organic-pest-control-that-really-works/
