From Avocados to OG Kush: Companion Planting with California Natives

If you’re growing cannabis at home in California, chances are you’ve already got a pretty solid green thumb - or at least a sunny corner of your backyard. But what if you could boost your cannabis health, increase your yields, and make your garden more beautiful, all without adding chemicals or complexity? Enter: companion planting with California native plants.

What Is Companion Planting?

Companion planting is the art (and science) of growing different plants together that benefit each other in some way - whether it’s pest control, improving soil nutrients, or enhancing flavor and aroma. For cannabis growers, it’s an all-natural way to support your crop without synthetic additives or complicated systems.
And when you're planting in California, you have a unique advantage: a massive variety of native plants that are already adapted to your soil, sun, and seasonal changes.

Why Use California Native Plants?

California’s native plants are drought-tolerant, pest-resistant, and often attract beneficial insects like ladybugs, bees, and lacewings. This makes them perfect neighbors for your cannabis plants - especially if you want to avoid harsh pesticides or fertilizers.

Here’s what native plants can do for your cannabis grow:

• Naturally deter pests like aphids, spider mites, and whiteflies
• Attract pollinators and predatory insects to create a balanced micro-ecosystem
• Improve soil structure and microbial life
• Help with camouflage if you're trying to keep a low profile
• Conserve water (super important during California drought seasons)

The Dream Team: Native Companions for Your Cannabis

Here are a few all-star native plants that pair well with cannabis in a residential setting:

1. Yarrow (Achillea millefolium)

Why it works: Attracts ladybugs and parasitic wasps that eat aphids.
Bonus: Drought-tolerant and beautiful when in bloom.

2. California Poppy (Eschscholzia californica)

Why it works: Draws in pollinators while deterring some root pests.
Bonus: It’s the state flower - and it's legal to grow in your yard.

3. Narrowleaf Milkweed (Asclepias fascicularis)

Why it works: Supports biodiversity and brings in beneficial insects.
Bonus: You’ll be helping out the monarch butterflies too!

4. White Sage (Salvia apiana)

Why it works: Strong aroma repels pests and masks the scent of flowering cannabis.
Bonus: Sacred, medicinal, and great for smudging.

5. Deergrass (Muhlenbergia rigens)

Why it works: Deep roots help aerate soil and prevent erosion in sloped backyards.
Bonus: Adds texture and movement to your grow space.

6. Manzanita (Arctostaphylos spp.)

Why it works: Acts as a habitat for beneficial insects while providing excellent ground cover.
Bonus: Beautiful red bark and year-round visual interest.

Tips for Planning Your Companion Garden

• Mind the spacing: Don’t overcrowd your cannabis plants. Give them room to breathe.
• Rotate seasonally: Some natives are annuals; plan for their bloom and die-back cycles.
• Mulch with intention: Use mulch made from native plant materials for the best results.
• Water wisely: Even drought-tolerant plants need help during intense dry spells. Group plants with similar water needs.

Do Natives Affect Terpenes?

There’s growing curiosity (and some anecdotal evidence) that certain companion plants can enhance terpene profiles. Aromatic herbs like white sage and native mints may influence nearby cannabis through shared soil chemistry and subtle environmental effects. While science is still catching up, California growers say they’ve noticed richer, more complex aromas in their OG Kush, Blue Dream, and Sour Diesel when paired with certain herbs and flowers.

Companion planting with California natives isn’t just trendy - it’s smart, sustainable, and perfect for residential growers who want to keep things organic and low-maintenance. Whether you're growing in Humboldt, the Central Valley, or a sunny SoCal backyard, your OG Kush will thank you for the company.
