Growing Cannabis with Classic California Crops

If you're lucky enough to grow weed at home in California, chances are you’ve got more than just cannabis in your garden. From citrus trees and heirloom tomatoes to backyard avocado trees and rows of rosemary, Californians are known for cultivating a rich mix of edible and aromatic plants. But did you know these classic crops can actually benefit your cannabis?

Whether you're gardening in a sunny SoCal yard or nestled among NorCal redwoods, this guide will show you how to grow cannabis with your other California favorites - not in spite of them.

Why Companion Planting Works

Cannabis thrives when surrounded by the right plant allies. These “companions” can help:

• Improve soil health
• Attract pollinators and beneficial insects
• Repel pests naturally
• Provide shade or ground cover
• Enhance flavor and terpene profiles (yes, really!)

California’s climate and agricultural heritage make it the perfect place to explore this strategy.

Cannabis + Tomatoes: The Fruity Friendship

Why It Works:

Tomatoes and cannabis enjoy similar soil pH, watering schedules, and sun exposure. They’re both heavy feeders, so keep them well-fertilized.

Tips:

• Space plants well to prevent airflow issues.
• Watch for shared pests like whiteflies and spider mites.
• Use trellises to train both vertically and maximize airflow.
• Their scents can confuse pests and reduce infestations on cannabis.

Cannabis + Citrus Trees: Scent Shield & Pest Repellent

Why It Works:

Citrus trees - like oranges, lemons, and mandarins - can help mask the smell of your cannabis during flowering season, especially in suburban neighborhoods.

Tips:

• Don’t crowd your cannabis under the tree; use partial shade to your advantage during intense heat.
• Citrus peels can also be used in homemade pest sprays or mulch.
• Keep citrus trees healthy - disease-prone trees can attract harmful bugs.

Cannabis + Avocado Trees: Deep Roots, Deep Benefits

Why It Works:

Avocado trees have deep taproots that won’t compete with the shallow roots of cannabis. They create light shade and cool the soil in California’s hotter inland zones.

Tips:

• Avoid planting too close - give cannabis 3–6 feet of clearance.
• Avocado leaf mulch is rich in nutrients and makes great compost.
• Both benefit from organic feeding and similar watering rhythms.

Cannabis + Herbs: California Flavors That Keep Bugs Away

Plant these near your cannabis for added flavor (to your meals) and protection (for your buds):

• Basil – repels aphids, mosquitoes, and flies
• Rosemary – deters caterpillars and adds aroma to the air
• Lavender – attracts pollinators and looks great in the garden
• Cilantro – lures beneficial predatory insects

Many herbs also enhance the terpene environment, subtly influencing aroma and possibly even taste.

Cannabis + Peppers: Spicy Allies

Why It Works:

Peppers repel pests like aphids and thrips. They also thrive in similar warm, sunny conditions.

Tips:

• Use hot pepper sprays (diluted!) as a natural pest repellent for cannabis leaves.
• Keep an eye on soil pH and nutrient levels—both plants love a well-balanced environment.
• Mulch around both to keep roots cool in peak summer.

Bonus: Don’t Forget the Flowers

Marigolds, nasturtiums, and sunflowers are California staples and cannabis companions!
They:

• Deter root-damaging nematodes
• Attract ladybugs and lacewings
• Add color and cover to your grow area
• Act as early warning systems for pests

Final Tips for a Harmonious Grow

• Rotate your crops to avoid depleting the soil in one area.
• Mulch heavily to conserve water and fight off weeds.
• Compost locally using leaves and scraps from your whole garden.
• Group plants by water needs to prevent over- or under-watering.
• Observe often - companion planting works best when you watch for signs of stress or imbalance.

Harvesting the California Way

Growing cannabis alongside avocados, oranges, tomatoes, and herbs isn’t just possible - it’s smart, sustainable, and delicious. This garden style reflects California’s laid-back, eco-conscious spirit and gives your cannabis a true taste of home.
