Problem
Chickweed has very hairy ½ long lance-shaped leaves that grow in direct sunlight. The leaves are directly attached to the stems and don’t have a leaf stalk. The weed produces starlike white flowers that bloom from April to October. The weed is often found in lawns that are thinned out due to insects, disease or mechanical damage. It reproduces through seed germination and by the stems that root easily wherever the joints touch the soil. Chickweed also crowds out other grasses due to the dense mat growth
Life Cycle
Active growth happens in the early spring or late fall.
Solution
The best defence against chickweed is a healthy lawn. If your lawn is fertilized regularly, mowed accurately and irrigated properly it will be able to withstand and choke out a weed invasion. First and foremost, watering deep but less frequent will allow the roots of your grass to deepen and in turn prevent the growth of all kinds of weeds. If we think about how seeds germinate like a newly planted lawn, the more often we water the more likely new grass seeds would germinate. So, anything we can do to avoid providing constant moisture to a weed seed bed by watering deeply enough that the existing plants have water in their root zone and even if a new weed germinated, it wouldn’t be able to source enough water long enough to survive.
Always keep your lawn around 3” long, this will give your soil some shade and will prevent any weeds from germinating, especially along the edges. All seeds regardless of type need sunlight at the soil where the seed is present to germinate, so remembering that like mulch in your gardens, if we can prevent the sunlight from reaching the seed when the conditions are favorable for germination, the seed won’t germinate.
If you do get the occasional weed on your lawn, the best solution would be pulling out the weed with its roots or by applying a selective weed control product that is available at your local retail outlet.
