Orange Hawkweed Control

As one of the List A weeds on the Colorado Noxious Weeds Act, it’s not surprising that there are effective methods to control the growth of orange hawkweed. The best way to control the hawkweed is to prevent plantation, but that isn’t always possible. Here’s a look at your control options if you find it in your garden.

Avoid Mechanical and Biological Options in Orange Hawkweed Control

The removal of the weed yourself is not recommended as an effective method to get rid of the weed. Just the slightly part of root or the smallest seed left behind will cause the weed to come back. It’s reproduction rate is strong and it will replicate around the area extremely quickly. There are no biological agents to control orange hawkweed.

Cultural Orange Hawkweed Control May Be an Option

Sometimes it is possible to control the growth of the weed through other plants. The plants will all compete for the fertilizers, helping to prevent many going to the weed. This has been effective in areas with depleted nitrogen levels within the soil and on rangelands. For other areas, herbicide treatments are the best.
Getting the Right Herbicide
Herbicides are the most effective way of getting rid of an outbreak. They should be used between spring and early summer. This is when the weed is in the reproductive stage and hasn’t flowered yet. Using the herbicides in the fall is ineffective. Combining herbicide and cultural options is the most effective method.
Just getting rid of one round of weeds is not enough. They can stick around with one bit of root. You’ll need to keep an eye on the area to make sure you didn’t miss anything. Apply the herbicide the next spring/early summer to prevent anything growing again in the area. Monitor for eight years to make sure the weed doesn’t come back.
