Natural Methods To Get Rid Of Common Garden Weeds

How to Get Rid of Weeds in Flower Beds (4 Easy Steps)

With so much controversy surrounding the use of chemical weed killers, especially those containing glyphosate, many gardeners are turning to more organic and natural weed control methods to deal with weeds even if it means more work. If you would like to get rid of weeds without harsh chemicals, here are 10 ways to knock them out.

  • NATURAL WEED KILLERS: Post-emergent herbicides target and kill growing weeds. They are available in spray forms that enter through the foliage, or granular forms that are watered into the soil and penetrate through the roots.There are two types of post-emergent formulas:
  • Systemic formulas that absorb directly into the plant and are best on perennial weeds
  • Contact formulas that kill only the exposed part of the plant and are more useful for annuals or smaller weeds
  • Common weed killers to try:

  • Safer Brand Weed Prevention Plus

  • DIY WEED SPRAYS: Homemade salt, vinegar and dish soap mixtures can be effective on some weeds, but should be used sparingly. Although they may sound safe and harmless, the ingredients can be harmful to the soil. Too much salt can cause soil to become toxic to plants and the vinegar can change the soil pH. Also, beware of using vinegar if there are amphibians near, as it can be harmful.
  • GROUNDCOVER: Plant a quick-growing groundcover to give the weeds competition for soil and water such as creeping phlox, creeping thyme or dragons blood sedum.
  • Common Winter Annual Weeds

    Hairy bittercress;, yellow rocket; and whitlow-grass; are all members of the Mustard family, which grow as rosettes close to the soil surface before sending up flowers on vertical stems. The leaves of hairy bittercress are usually 3 inches or less in length and covered with fine hairs. The leaves of yellow rocket can be up to 6 inches long and are smooth.; Whitlow-grass has the smallest rosette of Mustard family discussed, no bigger than 2 inches in diameter. Leaves are oblong and covered with fine hairs.

    These plants all produce flowers on upright stems. Hairy bittercress and whitlow-grass both produce small white flowers with four petals, deeply lobed in whitlow-grass. Yellow rocket produces yellow flowers, again with four petals characteristic of this family.

    Henbit; and purple deadnettle; both have the characteristic square stem of plants in the Mint family. The leaves of both are deeply veined covered with soft hairs, but the leaves of purple deadnettle are triangular and the upper leaves are often purple in color. The leaves of henbit are more rounded to heart-shaped.

    Common chickweed; is a member of the Pink family that grows prostrate . It has yellow-green opposite leaves with pointed tips and dainty white flowers with five deeply lobed petals.

    Ground Ivy Or Creeping Charlie

    Better known as Creeping Charlie, was first brought here from Europe because of its medical uses, like reducing eye irritation. This cool season perennial weed is resistant to a lot of herbicides. This weed thrives in moist shady areas, but it will grow in the sun. Also a part of the mint family, and gives off a mint smell when mowed. This weed can vary in length, from a few inches to a several feet. If trying to get rid of this weed use a herbicide that has Quinclorac in the ingredients. This is normally used for treating crabgrass, but it will effectively treat Ground ivy, Crabgrass, clover and Knotweed.

    How To Prevent Speedwell From Coming Back

    Once youve completed the labor-intensive process of ridding your lawn of speedwell, make sure you wont see their tiny blue blooms again come spring with these steps:

    • Lawn care best practices:Keep your lawn healthy to deter a speedwell invasion. Fertilize appropriately for your turfgrass and region, aerate the soil in the autumn and mow regularly. Speedwell thrives in moist, shady areas so make sure your lawn has adequate drainage and gets lots of sunlight.

    • Flower and seed pod removal: If the plant is already on your lawn, says MacKenzie, carefully remove all the flower heads before they bloom and shed seeds on the ground. This way you will reduce the probability of speedwells growth next year to a minimum.

    • Chemical herbicides: For serious infestations, you can use a pre-emergent broadleaf herbicide in the spring. Again, use with care. Herbicides may harm pets, children, pollinators and other wildlife, and applying to large areas also contaminates nearby groundwater.

    Lawn Weed Identification And Control Tips

    How To Get Rid Of Corn Speedwell In Lawn

    Corn speedwell is a winter annual weed that is classified by herbicide manufacturers as hard to control.

    It is not usually found in thick, healthy lawns but can be a problem in thin, weak grass stands and newly seeded areas; where it is capable of forming dense mats.

    Many of the pictures below were taken in shady areas, under pine trees and on the outskirts of highly maintained park lawns. I have also found it overtaking neglected lawns, in landscape beds, and growing in sidewalk cracks.

    Like many other Veronicas, this is a cute little plant with tiny, bright blue flowers; however, it is very is invasive and found on noxious weed lists.

    How To Control Creeping Speedwell

    Creeping speedwell, or Veronica filiformis, is a kind of weed that can feature blue and white flowers. It is a low-lying, spreading perennial that forms a dense mat over lawns. In addition to flowers, the plant features small, roundish, light-green leaves, and it spreads through thin stolons rather than by seed. Control creeping speedwell in yards through cultivation and other natural methods because all kinds of speedwell are hard to eradicate with herbicides.


    Maintain a healthy lawn. A healthy lawn does not provide an environment in which creeping speedwell can flourish. Nourish your lawn with a lawn feed appropriate for your kind of turf in spring and summer. Loosen soil in autumn to aerate it, and apply an extra layer of quality soil — to top dress the area — if necessary. Do not mow your lawn too closely to the soil because taller grass smothers creeping speedwell.


    Cultivate soil to rid your property of creeping speedwell. This task can be accomplished by rototilling or hoeing affected areas. Dispose of the plant in a garbage container or allow it to dry out before adding it to your compost heap.



    More About Corn Speedwell

    Corn speedwell actually belongs to the plantain family, and it grows in the early spring and summer through seeds. It has low-growing, branching stems that turn upright and produce 1/4-inch to 1/2-inch flowers with white to blue petals, sometimes with darker blue stripes. The leaves grow in clusters with pointed tips but have nonserrated margins. One of their other identifying features is their hairy stems and leaves.

    The Old Farmers Almanac describes a few other varieties of speedwell, all of which are low-growing perennials. Sunny Border Blue speedwell is a hybrid that grows up to 20 inches tall with dark, purple-blue flowers. Also a hybrid, the Red Fox is renowned for its attractive, deep-pink spiked flowers.

    Understanding The Crabgrass Cycle

    Crabgrass is a warm-season annual that germinates, lives and dies all in the same year. But crabgrass problems don’t end with the growing season. While they live, each crabgrass plant produces up to 150,000 seeds.1 Those seeds stay behind, ready to germinate the following spring and start the cycle all over again. Seeds that don’t germinate right away can remain viable and stick around to germinate in future years.

    Once crabgrass seeds germinate and plants emerge, mowing your lawn short won’t stop the seeds. With its low-growing, crab-like growth, crabgrass can set seed when cut as low as 1/2 inch tall1 that’s much lower than recommended healthy mowing heights;for any common lawn grass. Effective control requires preventing crabgrass seeds from ever becoming seed-producing plants.

    Low-growing crabgrass seeds escape mowers.

    Speedwell And Chickweed In New Lawn

    We took a county extension office workshop last year on lawn renovation. We followed their instructions and the results of our soil test last fall to kill off old lawn and start a new one . Grass came up–not super thick, but looked pretty good, and we were able to mow once in November, followed by a second fertilization at Thanksgiving. We thought we were done until next fall, with the exception of mowing in the summer.

    This spring we have a huge amount of weeds. The extension office has identified them as chickweed and speedwell . There are way too many to pull. I have read somewhere that we have to get rid of them now before they seed. Is it too late? When do they seed? What is the best way of killing them? Then what? Do we also have to lay down a pre-emergent of some kind for perennial weeds, or is this best addressed all in one step? Please help!Thanks!

    Woodrush Hairy Coarse Leaves

    If the conditions are right this weed can be present in the lawn all year round though it is most obvious during its flowering period in the early spring.

    This plant favours wet acidic conditions but it appears now to establish in any lawn to some degree regardless of acidity.

    • Likes sandy or acidic soils though any lawn can be infested
    • Adding ground limestone may help but may also invite other weeds and coarser grasses
    • Hairy leaves prevents contact between leaf and weed killer so is hard to kill
    • The plant is also resistant to most weed killers
    • Digging them out is the best approach
    • Though not guaranteed it is possible to treat with weed killer in late summer or autumn when the hairs on the leaves are less prevalent.A repeat application will more than likely be needed 6 weeks after the first

    Aerate Your Lawn To Relieve Soil Compaction

    Soil compaction occurs when you use a lawn heavily. This could be kids spending the summer playing on it or certain areas being used regularly, like the washing line or the route the postman;takes over your lawn to get to the letterbox.

    However it happens, the activity on the lawn pushes the soil particles under the surface, closer and closer together. This squeezes out water and air while at the same time, making the ground harder.

    This does two things;

  • It starves the grass of the nutrients it needs to produce food and grow, and
  • It makes it hard for the roots to grow because the ground is so hard.
  • Aerating the lawn involves spiking it and/or removing cores of turf via hollow tining .

    Aerating creates holes that are usually 2-3inches deep in the surface of the soil. These holes allow water, air and nutrients to work their way into the soil to the root zone of the grass. The grass can then consume these nutrients, produce food and grow strong, resulting in a lawn full of healthy grass with no room for Slender Speedwell to grow in.

    Just because Speedwell loves fertile soil doesnt mean you should avoid fertilising your lawn.

    Grass grows best in soil that is rich in Nitrogen, Potassium and Phosphorous.

    Remember, the best way to prevent weeds from growing is to create the best conditions as possible for grass growth. This leaves no room for weeds to germinate.

    So fertilise your lawn.

    Your grass will thank you for it.
