Controlling Mature Woodsorrel In Different Environments

Identifying and controlling Yellow Woodsorrel

The methods of controlling mature Woodsorrel are similar to those of controlling germinating seeds, but they would be done with more care and with greater consideration for the environment, since the weed is already mature and has deeper roots.

  • Woodsorrel in garden beds

There is only one organic approach in this case, digging out all the weeds inclusive of the roots to ensure that there are no pieces left behind. This is rather impractical, though not impossible, depending on the size of the garden bed and level of weed infestation this is because the weed roots are very small and the tiniest piece left behind can easily sprout into more weeds. You may even need to temporarily dig out your primary plants to sift through the soil looking for root ruminants. A way to make this approach more effective would be following it up with mulching to prevent any remaining roots from sprouting.

The best inorganic solution of creeping Woodsorrel would be a Glyphosate herbicide or fertilizer. This is because the chemical has the ability to kill the whole plant plus the roots, preventing them from sprouting again. Most weed killers do not affect creeping Wood sorrel as would be desired, leaving traces behind that simply sprout to form more weed coverage.

Mow The Lawn On A Regular Basis


Cutting the grass is the single, most important part of maintaining a healthy lawn. At the same time it is also the most overlooked aspect and as such, so many people do it wrong.

Its vitally important that you cut the grass regularly. At least every 10 days between April and October. When growing conditions are at their best cut the grass every 7 days.

Heres why

Between March and October, grass grows co and if you let it, it will keep growing upwards. By cutting it regularly you stop it from growing upwards so it looks for other ways to grow.

As a result, it grows side shoots called runners which sprout new grass leaves. Its these new runners and new grass leaves that create a lawn that is thick with grass.

Because the grass is so dense, weed seeds very rarely make it to the soil to germinate. Even if they do, the grass outcompetes them anyway.

However, if you cut the grass every 6 weeks when you can be bothered the grass will continue to grow upwards. It wont need to grow sideways so it wont ever be as thick as it could be.

Theres another issue with irregular grass cutting too.

As you cut the grass short youre almost guaranteed cut too much off the leaf. The leaf not only stores food and water but also traps sun so the grass can keep producing food via photosynthesis.

When you cut too much off the leaf, you take away the grasses food and water supply. You also take away its ability to create more food because there is no leaf left to trap the sunlight.

How To Get Rid Of Wood Sorrel Weed

Weed of the Week #887 – Yellow Woodsorrel (Air Date 4/5/15)

Wood sorrel is a troublesome weed that is difficult to control, especially in mild climates were it blooms year-round. The weed spreads through seeds and by horizontal stems that take root where the joints touch the ground. Each seed pod has the potential to hold as many as 5,000 seeds, but usually contains 10 to 50 seeds. When the pod matures the seeds are expelled forcefully, and may land as far as 10 feet away. The seeds travel greater distances by adhering to clothing, garden tools, pets and wildlife. Watch for shamrock-like foliage that folds down the middle on especially hot days and at night. The flowers are bright yellow and less than 3/4 inch in diameter.


Pull up young wood sorrel plants before they have a chance to bloom. Dig up mature plants with a hand trowel, making sure that you get the entire tap root. The weed will reemerge if you leave bits of root in the soil. Use a hoe to dig up plants in severely infested sites.


Cover the ground with a 2- to 3-inch layer of mulch in infested areas to prevent the seeds from germinating. The mulch blocks out light, which is necessary for wood sorrel seeds to germinate.



Treat wood sorrel in warm-season turfgrass such as Bermuda grass, Buffalo grass, St. Augustine grass, and zoysiagrass with a postemergent herbicide containing the active ingredient fluroxypyr. As with triclopyr, follow the label instructions precisely.

How To Prevent Creeping Woodsorrel

This involves ensuring that the weed does not have the opportunity to seed and spread out through your planted vegetation. There are a few measures you can take to prevent creeping Woodsorrel:

  • Ensure that you maintain a thick and healthy turf growth. This is because creeping Woodsorrel thrives in fertile open soil, so maintaining a thick turf reduces the area it can sprout on.
  • Sod or seed any bare spots on your lawn. As mentioned above, Woodsorrel thrives on open soil, so seeding bare spots also reduces the area it can potentially sprout on.
  • Keep your lawn watered and well fertilized. This is because creeping Woodsorrel thrives in well drained dry soil, so frequent watering and periodic fertilizing would make the soil an unsuitable environment.
  • Measure the pH of your soil. Creeping Woodsorrel thrives in basic soil Therefore if your soil acidity is less than 7, there is little chance of a Woodsorrel infestation.
  • Mulch your garden beds with a layer of organic mulch . This prevents the weed from growing beside the plant by cutting off any potential access to sunlight. Creeping Woodsorrel does not do well in shade and the weed seeds will not germinate. This method is great because it also provides fertilizer for the primary plant.
  • Air spray or wash your lawn mower and other farm implements after using them in an area with Woodsorrel. This is because seeds from the weed or root particles could attach themselves to the farm implements and would be spread to an unaffected area.

Controls For Yellow Woodsorrel

Hand-weeding or mechanical removal can be tedious, but it is effective if all therhizomes are completely removed from the soil. Shallow tilling can aggravate the problem by breaking up and spreading the vegetative parts. Landscape fabric or other impervious mulches can be effective. In landscapes and nurseries, the pre-emergent herbicides indaziflam , isoxaben and oryzalin effectively control this weed prior to germination. Indaziflam can control it when applied during early stages of growth as well. Pre-emergent herbicides, such as isoxaben , pendimethalin or dithiopyr are effective to prevent establishment from seeds in cool-season turf. In landscapes and nurseries, once the weed has emerged, using a hand-held weed wiper to carefully apply glyphosate can be effective to manage yellow woodsorrel. Application of a systemic herbicide containing triclopyr or 2,4-D + dicamba can help control yellow woodsorrel after it emerges in turf.

Yellow Wood Sorrel Vs Clover

Identifying and controlling yellow woodsorrel

Yellow wood sorrel, or common yellow oxalis, is very commonly mistaken for clover. However, these are two completely different weed species. Yellow wood sorrel has a compound, three-petaled leaf shape, much like clover. However, the leaves of the Oxalis plant are heart-shaped, while clover has oval-shaped leaves with a textured appearance. The easiest, most obvious way to tell these weeds apart are by their flowers: Yellow wood sorrel has a yellow, 5-petaled flower, while white clover or strawberry/red clover has a white or pinkish-red flower that is shaped more like an umbrella or Christmas tree light.

Treating Wood Sorrel In Garden Beds

In garden beds, the only organic approach is to carefully dig out the weeds, roots and all. This is a difficult task because the roots are tiny and the smallest piece left behind will resprout into new weeds. And you may need to dig up ornamental plants briefly in order to sift through the soil and remove the offending wood sorrel root. For many gardeners, the battle with wood sorrel is one they simply resign themselves to as an expected struggle.

Glyphosate will kill the entire plant, roots and all, so it is the most effective chemical solution. Other narrow-spectrum weed killers don’t touch wood sorrel.

How To Get Rid Of Yellow Woodsorrel Weed

I have a weed in my perennial garden which I have IDÂed as Yellow Woodsorrel .They look like little shamrocks. It appeared in one bed last summer and I ripped it up as soon as I saw it but it was a foot high by then. Now this year it is everywhere. I tried ripping it out manually but unlike most things that you can pull out by the roots, this plant just breaks off at the surface leaving the roots behind. When I go back a few days later it has grown new leaves, without hardly missing a beat. Complicating matters is at first glance they look like columbine seedlings, which I do want. You have to look really close.

Anyone know how to control this? In researching removal, everything I have found refers to lawns and not gardens so I donÂt know if a particular chemical would kill perennials too but I expect it would. I thought of just cultivating around each perennial but have never tried this before for any weed, preferring a vicious yank and toss instead. I am afraid the resprouting abilities of this weed may make that a waste of effort.
