Remember: One year's seeds, seven years' weeds!
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 so they 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 should be able to avoid 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 mow them off continuously. 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.
Crowsfoot grass is a summer annual that grows in easy to identify tufts, staying fairly flat to the ground with almost white flat sheathed stems and smooth strap like leaves. Crowsfoot grass is a difficult to control weed that can tolerate low mowing and will thrive in nutrient deprived and compacted soil conditions.
How to treat crowsfoot
The best way to remove crowsfoot is to chip out by hand. Make sure when doing so that you carefully remove the entire plant and don’t spread any seeds during the process.
You can also treat the individual tufts of Crowsfoot with a glyphosate type product like Round Up or Zero. Just be careful when doing so, as anything you touch with the product will likely die including your lawn! We recommend to use a paintbrush or similar to target just the weed with this product.
