Common weeds and how to control them
It is a fact of life that if we have a lawn and garden we will have to deal with weeds from time to time. The trick is to control weeds early rather than let them get out of control and set seed all over your yard – this is bad news! Some single plants can produce up to 10,000 seeds.
By keeping your lawn fed, watered and healthy you will not have many problems with weeds. A healthy lawn will suffocate most weeds. Hand removal is always the best way to remove weeds. Mowing regularly can also stop weeds from setting seed. Most problem weeds grow and take over lawns during the winter season.
What is a soursob?
Soursobs present as a dense mat of clover-like leaves along the surface. It is extremely hard to kill, especially in lawns, as it has a fast-growing onion-shaped bulb system. Autumn and winter is when soursobs are at their peak growing stage. Cultivating is certainly not recommended during this time, as it will spread the rhizomes further, which will result in more bulbs to form.
How to manage soursobs
The best way to manage soursobs is to let them grow to flowering stage and then mow them off. This attacks the weed at its weakest stage. As your lawn roots establish, they will suffocate the soursobs, resulting in them dying.
Another method which can be more timely is to use a paint brush with glyphosate and paint each individual plant, making sure to get NONE on your lawn as it will kill anything it touches.
Two steps to a soursob free lawn
- Mow the soursobs weekly to make them weaker
- Glyphosate the weed when flowering
A dark green clumping grass that occurs in lawns in winter season. Normally germinates with first large rain of season and continues through to Spring. Rye Grass is sometime used as a type of cool season grass cover, however mostly rye grass is a weed problem in warm season lawns. Control with hand removal or selective herbicide Winter Grass Killer
Kikuyu is a common grass variety; however, it is highly invasive by nature and ends up in gardens and lawns where it is not wanted. Kikuyu can be very hard to eradicate as it grows above ground and underground, popping up in gardens and pavers.
Digging out and removing contaminated areas is the most effective way of removing this weed.
Cudweed is identified by having rosette shaped, flat, shiny, mid-green leaves. The cudweed has various small flowers on its stems with fibrous roots. Cudweed is difficult to kill due to its glossy leaves. Cudweed may need two or more applications of Buffalo Weed Control. Buffalo Weed Control is a broad leaf herbicide safe to use on Buffalo, Couch and Kikuyu lawns. You may also find that hand-removal of the weed is helpful.
Dandelions have toothed leaves that are light green. They are identified by their solitary, double-yellow, daisy like flowers on hollow stems, milky sap, rosette shape and thick contractile, fleshy tap-root. Control with hand removal or spot spray herbicide Buffalo Weed Control. Buffalo Weed Control is a broad leaf herbicide safe to use on Buffalo, Couch and Kikuyu lawns.
Bindii or Caltrop
Possibly the most annoying lawn weed due to the pain caused by the seed to bare foot. Caltrop is indentified by their finely dissected, small, fern like leaves light green in colour, they have small green flowers deep in leaf axis and fine, fibrous roots. Bindii are indentified by a flat, small compact rosette. Bindii are small brown, flat seeds with sharp spines that hurt bare feet.
Control via hand-removal or selective bindii herbicides, such as Buffalo Weed Control. Use herbicides during winter or early autumn before the plant sets seed. Luckily bindii and caltrop are easy to control if you get onto it early.
Creeping Oxalis are identified by their small, light green, clover like leaves on short petioles and small, yellow, bell shaped flowers. Creeping oxalis forms new roots wherever stems touch the ground, creeping under and through the lawn, with thin tap-roots. This plant is very difficult to remove as crown breaks off leaving roots for re-growth, it is a very invasive, nasty weed. Control by hand-removing small plants and digging out sections of lawn. Use Buffalo Weed Control herbicide for larger infestations. Control with hand removal or selective herbicide.
Clovers have green leaves with white circular markings, on thin stems, small white flowers, ball shaped on stems above leaves. Clovers also have tap-roots off stolons. Clovers are a weed in lawn, but in other areas can be beneficial due to high nutritional value. Four leafed plants are very lucky, so don’t poison those! Control by hand-removal and Buffalo Weed Control selective herbicide.
