lawn weed with flat sticky seeds

Suppress growth by applying a 2- to 3-inch layer of mulch such as pine straw or pine bark around shrubs and trees. Using landscape fabric weed barriers beneath the mulch layer will further hinder its emergence. Pull or dig out all plant parts, especially the tubers, when the soil is moist. Hoe or cut the top growth down to soil level repeatedly to “starve” the plant.

Examples of plant essential oil-based herbicides include:

Florida Betony

Most herbicides should not be applied during spring transition (green-up of lawn) or when air temperatures exceed 90 ºF as this can cause severe damage to the turfgrass. A newly seeded lawn should be mowed a minimum of three times before applying an herbicide. Rainfall or irrigation a day or two prior to herbicide application reduces the chance of turfgrass injury and enhances weed uptake of the herbicide.

Perennial mouse-ear chickweed (Cerastium vulgatum) looks like sticky chickweed, but it has creeping stems that often take root to produce new plants. It reproduces by seed and by producing new plants from ground-hugging stems that root at the nodes (the point of attachment of the leaves).

Proper identification of weeds targeted for control is necessary in order to select effective control measures, whether cultural or chemical. Further assistance with weed identification is available from any Clemson Extension office or the Clemson Home and Garden Information Center.

Mallow or marshmallow is native to Europe, Asia and northern Africa but has made itself at home in all Australian states. It grows in every soil type and is commonly seen in disturbed areas such as roadsides, cultivation, around buildings, stock yards, along watercourses and in rundown pastures. At Lawn Addicts, we provide recommended herbicides and lawn care programs to control mallow and other broadleaf weeds.

Onion Grass is a perennial grassy weed with between three and 10 thin, strappy leaves rising from the central base up to 30 cm long. The leaves are up to 2 mm wide with a prominent central midrib that protrudes to create an almost cylindrical leaf blade in cross section in a spear and quite a tough point. Flowering in spring, the onion grass plant produces two to four small flowers per plant that are positioned around the base of…

While one herbicide registered to work on a weed may be okay in one lawn, it may suppress, damage or even kill other lawns. Turf identification is an important aspect of weed treatment.

Lambs Tongue/Plantain (Plantago lanceolata)

Paspalum is a grassy weed with larger, broader, longer leaves. It grows in a cluster and is quite obvious to see in your turf. It comes in many varieties. Removing paspalum by hand involves digging the plant out of the ground, and the roots must also be removed. Selective herbicides are available to control this weed. These can usually be used on couch, bent grass, fescue and ryegrass lawns, but cannot be used on buffalo, kikuyu or saltene/bahia lawns. Always check…

Purslanes and Portulaca are a low growing 0 to 200mm high, a prostrate to decumbent often flowing succulent annual weed. Stems and runners are normally soft and pink to brown in colour. They are very common in a variety of soil types especially after having been recently disturbed. There are many varieties of this weed across Australia some native and introduced widely naturalised and a prolific seeder. Grows well in temperate to tropical regions. Seed mostly germinates around autumn, colonies…

Cudweed is an annual or biennial weed with a rosette forming growth habit. The leaves are broad and obovate (egg shape) in shape and possess a dull green upper surface with a soft, white or silver hairy underside. Growth begins as basal rosette forming stems with upward growth occurring as the plant matures. Cudweed flowers typically form from spring throughout summer and are purple to pink in colour. Depending on correct identification of turf, the team at Lawn Addicts recommends…

Dandelion is perennial weed which often become a nuisance in turf. It is quite drought tolerant with a deep tap root able to withstand dry conditions beyond what the turf can handle. On maturing, the yellow flowers become the fluffy white balls we know as “fairies”. The cycle of the dandelion can be controlled by regular lawn mowing whenever its flowers or seed heads are apparent, similar to capeweed with constant removal of its seeds. Hand weeding is easy and…
