Zone 9b August Planting Guide

July 31

Let’s Grow with the Zone 9b August Planting Guide

With the heat of August upon us, now is the time to begin preparation of our cool season garden.

The hot summer sun brings hearty vegetable yields and flowers in full color! Now is a great time to ensure your garden is receiving sufficient water and that no garden pests have made their way to your precious plants. It’s time to use our Zone 9b planting guide to prepare for cooler weather. Consider placing an order for your cool season seeds from a local heirloom provider. Hardy vegetables like broccoli, cabbage, kale and radishes thrive in the cool season and the most dazzling varieties tend to sell out quickly! Don’t forget our suggested flower companion planting guide this month to bring more pollinators to your garden and ensure your fall gardening is top-notch.

What is Companion Planting?

Companion planting is a very old-world, organic gardening method rooted in creating a diverse ecosystem of fruits, vegetables, herbs, and flowers grown int he same space. As a result of inter-planting, you’ll create a more habitable environment for plants, improve soil health, and reduce the resources needed to grow sustainable amounts of produce.

Consider inter-planting some herbs with your fruits and vegetables this year to attract more pollinators and help keep pesky bugs at bay.

With a long and tenured history, the practice of companion planning was primarily practiced by home gardeners who weren’t driven solely by efficient outputs. However, as the impact of climate change grows and concerns over the use of pesticides for health increase, more and more gardeners (both home and commercial) are starting to implement the practice of companion planting.
