How to Get Rid of Jimson Weed (Helpful Tips!)

Jimson weed which is also called Thorn apple belongs to the genus Datura. It’s an aggressively invasive and poisonous plant. It grows widely in temperate regions.

It is an annual weed and is competitive with many garden plants. You wouldn’t want this weed in your garden as it’s proven to be poisonous to humans, cattle, and pets.

Let’s see how you can get rid of this weed.

Jimson Weed Eradication

I advise you to wear protective clothing before you even touch this plant.

Organic way

Going the organic route is quite hard and takes a lot of time.

Wear a pair of garden gloves and protective eyewear and clothing that covers your body entirely if possible. These precautions are necessary as jimson weed has been proven to irritate eyes and skin.

Pulling it out

Pull the jimson weed out of the soil along with its roots. Throw it in a sealable trash bag. The weed is easier to pull from the ground if you water the soil well a day before.

Do this weekly if you want to have a landscape free of these monsters. You can use a weed torch or a digger, but make sure to get rid of them as soon as they sprout.

Do not let these plants flower, if they do they’ll soon release seeds into the soil and you’ll be fighting them for years.

If possible, mow the area regularly/weekly to keep the weed from flowering.

Cover crops

You can plant a cover crop that prevents the germination of any seeds already in the soil. Sudangrass can be a great cover plant as it is known to prevent weeds from sprouting.

Jimson weed is allelopathic, so it’s better to plant fully grown plants instead of seeding.

Use it as compost

It grows aggressively and if you keep plucking jimson weeds, you can use it to make compost. Jimson weed decomposes well and it is completely safe to use its compost.

Whenever you pull out jimson weed, throw it in a sealable trash bag. You can now use it in your compost mix.


You can solarize your garden beds to prevent any jimson weed from sprouting. This usually takes 4 weeks to 8 weeks. But this works well.

It is a tedious process if the problem is on a farm. In such cases, herbicidal control is apparently an efficient option.


Using herbicides to eradicate the jimson weed is an efficient way to do it. Spring is the best time to spray herbicides when the weed is actively growing.

Broadleaf herbicides work well on jimson weed. Herbicides like 2,4-D are proven to work on Jimson weed. Glyphosate works well on jimson weed as a post-emergent.

Once the jimson weed is dead, you may need to use a pre-emergent to control new jimson weed sprouts from the soil.

Pre-emergents like flumioxazin (BroadStar/SureGuard) and oxyfluorfen work well on jimson weed seeds.

Note: After pulling it out manually, you may need to use a pre-emergent herbicide on the soil.
