Someone askes
John is looking for a product to kill only clover in our lawn.
He has a sprayer and has tried Weed Be Gone which was ineffective.
Is there a better product you know of that will do the trick?

Gerry Says
Clover is or can be a problem with lawn care today
50 or more years ago- when 2,4-D was first invented- it did not kill clover- and people would put clover in the lawn on purpose.
It did help to keep lawns green by fixing Nitrogen out of the thin air and adding it to the soil
When 2,4-D was improved with an additive to control a broader range of weeds- clover was in the list - now clover was declared to be a weed.
Now some researchers have developed new strains of clover- Micro-clovers that grow a bit shorter and are more compatible with lawns.
Weed-b-gon, Fiesta and other similar products used by lawn care companies do not do a good job on clover. Treatments will cause the edges of the leaves to die- turn brown- but that does not consistently kill off the clover.
Clover is not used in lawns by itself as it has the problem of dying out every so often. So the patch of clover here today may disappear tomorrow or next year. Certainly being weakened by Fiesta iron can play a part in making in disappear. But there is no consistency in how or when it will happen.
There is no legal product that can be used on lawns for clover removal only- assuming that if the dandelions go that one would not be disappointed.
Only on a golf course could one use products that will control cover.

For the gourmet chefs- it seems that "baby" vegetables are the way to prepare foods in a new way. Baby carrots, baby spinach, baby peas. 

Is this a good thing for a world where we have a food shortage? If we let the crops grow to maturity, we would have more food. Instead of harvesting the vegetables when they are young, the same plant will produce a lot more edible produce if left to maturity. Are 'baby' crops a waste of resources?

Anyways, I digress.

Was harvesting some asparagus in the garden today. In the soil, I can see a few weeds starting to germinate. Clover and crabgrass. Clover will germinate with cooler soil temperatures- so I have been pulling them out for some time. 

Crabgrass on the other hand needs warm soil temperatures before it will germinate. In lawns that are shaded by the grass blades, it takes longer for the soil to warm up. In my asparagus bed, there is almost no shade. An asparagus spear casts very little shade. So here is a photo of a "baby" crabgrass. The crabgrass seedling is just starting to grow. Just before pulling it out, I thought a photo may be helpful.

Baby Crabgrass, Seedling, Just Germinating

Young crabgrass plants are harder to identify. Once they become more mature, their characteristics are more easily noticed.  Then they are a problem for lawn care operators.

In a lawn with a good stand of grass, the soil will likely be still too cool for the crabgrass to germinate. If, however there is a patch of bare soil in your lawn, the crabgrass may have an opportunity to sprout and germinate.


We do tell people that weed treatments are not easy, Fiesta is the only registered product in Ontario that is labelled to control dandelions.

But if one uses the organic weed treatment on a regular basis. (Turf King recommends 4 treatments per year) and a lawn care program that provides top quality fertilizer to keep the lawn thick and healthy- much can be achieved.

Weed Treatments make a Difference in Lawn Care

The property in the foreground has been treated by Turf King for the past 3 seasons. It is irrigated and maintained by a Landscape company.

The lawn across the road- who knows what has been done-??

If you zoom in- you may be able to see a number of dandelions in the lawn in the foreground, but they are few and far between (not perfect by any means) and a great deal better than not doing anything.
