How To Get Rid Of Goat Heads

Goat heads are prolific seeders, with burrs strewn throughout your yard. Goathead (Tribulus Terrestris, USDA plant hardiness zones 4–11, but native to Southern Europe) is an invasive weed plant spread over most of North America, particularly in the Southwest and Rocky Mountain regions.

Goathead Characteristics and Goat Head Life Cycle

Goathead is a low-growing, deep-rooted shrub. It grows in arid locations in compacted soils, with a long deep taproot. As a result, orchards, gardens, pastures, and lawns are susceptible to pest infestation.

This is an annual summer broadleaf with a core taproot that spreads. It has four to eight leaflets that grow opposite its hairy leaves. It produces yellow blooms that are half an inch long.

Seedpods are five spiky burr clusters that contain up to five seeds each. Seedpods of goat heads are green at first, then gray or tan.

Each year, a single goat head plant can produce 200 to 5,000 seeds. Seedpods can remain dormant in the soil for up to five years as they wait for the proper conditions to sprout.

While the seeds require sufficient soil moisture and mild temperatures to germinate, once established, the plant can withstand most climate conditions in North America that are above freezing.

Weed pesticide to kill goat heads

Weed Killer Spray To Kill Goat Heads

A goat head is a perennial weed with a thick taproot. Hand-pulling is ineffective at removing goat heads because portions of the root that break off in the soil regenerate quickly.

As a result, use a weed killer spray that kills goat heads when they appear to get around this. Glyphosate-based weed herbicides such as Roundup and other Glyphosate-based herbicides successfully kill goat heads in gardens.

Use a specialized weed pesticide to kill goat heads without harming your grass.

The herbicide will take 1–2 weeks to take effect. While the plant’s top may droop in a matter of hours, it takes time for the weed killer to destroy the plant down to the root.

Burn Goat Heads With a Flame Weeder

One issue in weed killer sprays is that they do not kill weed seeds. The stinging burrs that goat heads drop are their seeds, which, if left unchecked, will sprout swiftly, and can still puncture bicycle tires long after other portions of the plant have been dead.

A propane weed-burning torch is an excellent weed-killing tool for eradicating invasive weed species. They’re a propane-tank-powered mini-flamethrower that’s perfect for torching weeds.

The propane flame in a flame weeder will not only kill the goat’s head plants, but it will also kill all the seeds, including bothersome goat head burrs.

Use caution when using a propane weed burner, especially if the lawn is dry or if the weather is windy during the summer.

Use the flame weeder in a controlled manner to burn the entire plant without injuring your attractive plant next door to ensure the goat head plant is eradicated.

First, discover any restrictions on how you can use it with your local fire department or city. For example, some jurisdictions require a burn permit, while others do not. (Learn What Are The Different Types Of Sticker Weeds)

Cover With Mulch and Landscape Fabric

After you’ve killed and eliminated goat head weeds from your garden, it’s time to prevent them from returning.

Most weed seeds must be within 1–2 inches of the surface to sprout. To prevent remaining seeds from sprouting, lay down water-permeable landscaping fabric in your garden and cover it with a 3–4-inch layer of mulch.

The landscaping cloth keeps goat heads from poking their heads through the mulch while still enabling water and nutrients to reach the soil in your garden.

Pebbles, synthetic mulch, or even newspapers can cover the landscaping fabric. Because goat head thrives in arid climates, many gardeners use desert-friendly rock and gravel groundcover to keep them under control.

You can gradually tear down an old carpet if you don’t have any landscape fabric. However, it does an outstanding job of preventing undesired plants from growing in the meantime.

It’s best to combine horticultural vinegar and a tiny amount of dish soap—the soap aids in the vinegar’s adhesion to the goat head leaves.

Some gardeners also use salt; however, this might alter the soil’s composition, inhibit the growth of other plants, and interfere with grass formation. Unfortunately, goat head weeds will not be killed by any form of this DIY weed killer.
