Orange County September Planting Guide

September 2

One of the joys of living in Southern California is that we get to garden year-round.

I firmly believe that it’s never too late to start a garden – especially in our lovely Mediterranean climate. And fall gardens are my absolute favorite to plan for myself – and clients.

With a new month upon us, now is the perfect time to get our hands dirty planting some new seedlings for another season of growing. Heirloom Potager is working on wrapping up a few new garden installations and will be planting in the neighborhood community garden this month. Check out what’s on the Orange County CA September planting guide.

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.
