Whiteflies On Marijuana Plants

Whiteflies tend to conceal themselves under marijuana leaves and they can be just as destructive. They are very small and spread diseases while eating one plant then going on to the next.

They will travel great distances releasing honeydew and spreading plant diseases in large amounts. Whiteflies will feed on the leaves and stems of marijuana plants and are one of the most harmful pests to your plants.

Your marijuana plant will show signs of damage from whiteflies. One of the mains signs is chlorosis deficiency, which is basically yellowing in the leaves. The leaves will start to dry up beginning around the edges, then falling off. The growth of the plant will also start to reduce and degenerate.

How To Get Rid Of Whiteflies

Companion planting is an excellent, natural way to stop whitefly attacks. Planting zinnia inside your plants along with the aforementioned marigolds will push them out of your yard and onto someone else’s.

Zinnias appeal to natural whitefly predators when they are a part of your garden. They gain the attention of hummingbirds, predatory wasps and flies, who like to prey on whiteflies. Hummingbird bush, bee balm, and pineapple sage are some examples of mint scented plants that hide the smell of any nearby plants that whiteflies are attracted to.
