Getting rid of that pesky Onionweed

Onionweed is one of thew worst types of weeds that can take hold in your lawn or garden, It can be eradicated however with patience and a bit of delicate work. Keeping onionweed under control by preventing flowering is a must to prevent it spreading any further.

What is onionweed?

Onionweed is a sedge-type weed and is a menace in lawns and garden beds throughout Australia. It is one of the worst weeds that you can have take hold in your yard and it is also one of the most difficult to get rid of. 

Onionweed is a perennial with thin green strappy leaves growing from a mainly white bulb which gives off an onion smell when crushed. Flowers grow at the top of a long stalk and are mainly white. Seeds form in summer and autumn and are spread mostly by wind blowing the seeds into the new areas.

It has a 'slow-release' way of sprouting its bulbets, making it a weed you just have to admire for its adaption and 'survivor' skills. Onionweed's thin, waxy leaves also make it difficult for herbicides to stick to the leaves, and even if it dopes, the wax makes it difficult for the herbicide to affect the plant. 

How to start the eradication process

Eradicating onionweed starts with removing as many of the plants as possible. Do not try to pull the plant out of the ground, or shake excess dirt back off into the hole or compost. The small bulbets tend to pull away from the mother plant when pulled, which leaves more bulbs in the ground that will rapidly grow.

If possible, dig the weed-clump out of the ground with a spade or a trowel, and throw the entire clump away.

The next step to total eradication of onionweed is to treat the area with either a non-selective herbicide (like Roundup/ Glyphosate) or even boiling water. Both options will kill any plant it touches, so be wary o surrounding plants. You will need to use a paintbrush or a weed-wand to carefully target the onion weed plants and avoid your lawn in possible. 

It can help to add a surfactant or a slight amount of household detergent - about the same rate as the herbicide concentrate amount - and when added to the mix helps the herbicide to stick to the waxy leaf and penetrate to do its work. 

Keep an eye out on your lawn, and repeat the process if any new onionweeds begin to grow. If your unable to treat the area, keep the plants trimmed near the ground if possible as this will prevent the onionweed from flowering and spreading to other parts of your lawn or garden through seeds. 

Hopefully this process will allow full eradication of onionweeds from your lawn and garden.Be patient, it can be a tedious exercise, but show no mercy, and don't give up hope. It will be well worth it to be onionweed free in the long run.

Things to do for your Lawn now before Winter Sets In


We have had an amazing autumn but its almost winter and we have a few tips for you to improve your lawn's appearance throughout winter. Don't attempt too many drastic actions; scarifying or topdressing at this time of year is a definite no no, but a last fertilise for the season and even a pigment treatment can work wonders for your lawn. 

During the cooler months lawn's will generally be at their most vulnerable and unable to repair or maintain good health as well as they can in the warmer seasons.

Most Australian lawns are what are known as warm-season grasses; Kikuyu and Sir Walter Buffalo lawns are a few of the most common types and fit into this category. As the name suggests 'warm-season' grasses are actively growing during these months and during the cooler months they slow down and can go dormant; shutting down or discolouring over winter.

This is a protection method that lawn grasses use to withstand freezing temperatures and frost with the grass leaves thinning and drying out and the plant's energy being stored in the lower parts of the grass stem and roots area. 

As the weather starts to cool down, so does lawn care with the grass not growing as vigorously as it did a few weeks ago in most cases. As daylight hours decrease, so does photosynthesis, so by increasing mower heights and leaving more leaf it will help increase the food supply to the grass.

Pruning is a great way to plan ahead for winter conditions, as overgrown trees and bushes may increase their shade levels and by the time we notice our lawn has started dying in certain areas, it can be too late to repair the damage.

Use this period as an opportunity to fertilise your lawn, and go for an all round or pre-winter fertiliser that contains higher levels of iron, which is essential for good lawn health throughout these cooler conditions and also gives a quick colour boost to your lawn.

It is important to address any weed issues before winter, as conditions for their survival improve, while at the same time the lawn's ability to fight against them decreases. Winter weeds such as poa (wintergrass), could potentially inhabit your lawn. Treating weeds before they spread is the best thing to do.

Patching up any bare or dry spots will help prevent issues during the cooler months, and will keep your lawn looking good - you can square up any areas with a mattock or spade and fit new turf sections straight onto your lawn. Give us a call if you need a turf roll or slab to patch up areas. 

As air and soil temperatures decrease, over watering during cooler temperatures can increase the possibility of lawn diseases or rotting of the thatch latch layer. Aerating your lawn during autumn in considered a good time to do so as the plants are busy enhancing their root zones in preparation for winter and the soil is usually a bit softer than at the height of summer. 

Use a garden fork and work to break up the soil or hire an aerator that will make quick work of the job. You will be amazed at the results - just check out any golf course and see how often they are aerating or coring to get more airspace into the soil profile.

Getting the mowing height right is probably one of the most important things now and its a good idea with the next few mows to increase the height and then you can gradually lower it over winter - not taking much leaf off but more of a tidy up. 

You will see this on many footy fields around the country as most sports turf curators start to lift the mower height at this time of the year to get a more healthy and robust cushion of turf in readiness for damaging winter sports.
