Fall has distinct planting benefits. Autumn’s cooler air temperatures are easier on both plants and gardeners. The soil is still warm, allowing roots to grow until the ground freezes. In spring, plants don’t grow until the soil warms up. While many of us in the Central Valley have done our part through the long days of summer to conserve water, we can relax knowing the shrubs and trees planted in autumn will benefit from cooler temperatures in the following months. Fall has more good days for planting than spring does, when rain and other unpredictable weather can make working the soil impossible. And you aren’t pushing the clock to beat the heat as you do in spring.
So, with all the benefits of fall, what should you be doing?
- Sharpen your tools in preparation for fall pruning.
- Shape your rose bushes while cutting and deadheading.
- Prune evergreen shrubs and hedges. They will have a few more months to push out new growth before frost.
- Clean up fallen fruit around the bases of fruit trees.
- Adjust watering systems as weather cools.
- Keep plants clean and free of dust to discourage spider mites.
- Feed your roses with ¼ cup each Epsom Salts and Ironite.
{Did you know?} Epsom Salts were originally named for the mineral springs of Epsom, England, although now they are commercially produced. Epsom salts are actually magnesium sulfate, not a salt. There is a trace amount found in our local water supply, but because of our alkaline soil, an extra dose of Epsom salts helps to neutralize it. This makes the roses grow more lush. Apply by sprinkling it dry around each rose bush and then water it in.

While September in Fresno is still too hot for planting annuals, most landscape trees and shrubs will benefit from fall planting and give you a great show in spring. Some of my favorite trees for the Valley are Crape Myrtle, Chinese Pistache, Flowering Plum, and Shamel Ash. Citrus, avocado, and other frost-tender plants should be planted in Spring after the danger of frost has passed. Hot weather is still occurring in September, so be careful to keep new plantings well watered.
Of course, I can’t mention water conservation without adding the importance of mulching. Along with keeping roots cool in summer and warm in winter, mulch also conserves soil moisture and prevents weeds from spreading. When it comes to landscaping, you can read more here to understand what needs to be done. I use it for the benefits, but mostly because it provides that “finished” look I’m after. To get the most benefit from your mulch, be sure to spread a 2 to 3 inch thick layer when using small particles. A 3 to 4 inch thick layer will be needed when using shredded bark or nuggets. I do small areas at a time to make it easier on my back and my wallet.
So, what garden projects will you be tackling this fall?
