This thread is for exploring companion planting in cannabis gardens.

 

A natural way to deter pests by using other plants as a pest 'deterrent or a trap' plant.

 

 

I'll kick it off with a link posted in another thread;

 

 

For spider mites;

 

HERBS

Chinese parsley (Coriandrum sativum) is an annual culinary herb, and a companion to dill, anise, caraway and potatoes,

that repels spider mites. A deterrent spray can also be made from an infusion, or strong tea, of the leaves. Most people

know this plant as cilantro, a name that specifically refers to the leaf. The seed, however, is known as the spice coriander.

Another annual herb said to repel spider mites is dill, which is considered an excellent companion plant to cabbage and lettuce. Certain herbs in the allium family -- garlic (Allium sativum) and chives (Allium schoenoprasum) -- reputedly benefit a variety of

plants and vegetables and specifically protect tomatoes from red spiders. Garlic and chives are perennials in U.S. Department

of Agriculture plant hardiness zones 3 through 8 and USDA zones 3 through 10, respectively.

 

 

FLOWERS

Chrysanthemum (Dendranthema grandiflorum) is a generic term for a variety of perennial flowers collectively referred to as

mums, most of which are hardy in USDA zones 5 through 9. As the source of the natural insecticide pyrethrum, mums are good companions for a variety of other plants, because they deter several common pests, including spider mites. Shasta daisy (Leucanthemum x superbum), a perennial ground cover and border plant suitable for USDA zones 4 through 10, attracts

beneficial species that feed on spider mites, such as pirate bugs and predatory mites.

 

VEGETABLES

As botanical cousins to garlic and chives, onion (Allium cepa) and leek (Allium ampeloprasum porrum) also benefit a variety of

other vegetables and ornamental plants while deterring red spider mites. Leek is hardy in USDA zones 7 and warmer, while onion, depending on the species and cultivar, is grown as an ornamental and a vegetable in USDA zones 3 through 9. Rhubarb (Rheum rhabarbarum), suitable for USDA zones 3 through 8, deters red spider mites and is beneficial to broccoli, cabbage and other cruciferous vegetables.
