Orange County May Planting Guide

April 20

Let’s Grow in Southern California

Spring is officially here which means it’s time to plant the summer garden! Evening temperatures are warm enough to move all your seedlings into the garden.

With your young warm season plants in the ground, start planning for succession sowing and stocking up on worm castings to make compost tea and feed your soil. Tomatoes, squash, and peppers can be hungry feeders. Check out our suggested flower companion planting guide this month to bring happy pollinators to your garden. Heirloom Potager will be refreshing gardens for residential clients and starting a new commercial design project. Check out the Orange County CA zone 10b May 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.
