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.

September or early October in Arizona is one of the best times to plant potatoes (not sweet potatoes). Try planting them in grow bags if you are short on space. Read this article to learn how to grow potatoes in containers. 

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).

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.

Pomegranates are ripening. I will probably wait until November to harvest them but check yours by picking one and seeing if the berries are a deep red for most varieties. Read this article to learn how to grow pomegranates.

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.
