Clover
Every speaking event I have ever done, one question that is asked all the time "How do we get rid of weeds like clover ??"
My late partner from Iowa, on his first trip north asked to see a clover lawn. He had heard so much about the clover lawns in Ontario, he just had to see one. As I told him that was before the chemical use on lawns. Clover is NOT A WEED. It was easier for the companies to teach you that clover is a weed, than to come up with a formula that would not affect clover. Clover brings nutrients and moisture from down deep (up to 35 feet in many cases) hence your lawn is healthy brix/sugar levels are high. Since the brix is so high, the chance of having an insect problem especially grubs are little to nil.
Because of the deep root of clover, moisture and nutrients are brought up by the plant and actually help the grasses and plants around each plant. Your lawn should stay green all year, even with drought conditions. (in Canada and many parts of the USA) a nice green cover about 3 - 4 inches in height - mowing becomes optional. Oh yes those little white flowers all over your lawn - believe me they don't bite -- Bees love them. If your concern is a green, healthy lawn then you want a clover lawn. In many cases, I hear the "neighbor doesn't like it" Now let me ask did you buy your property to satisfy your needs or those of someone else.
The companies say they have a weed killer to look after clover. A product that travels up to 35 feet down the root …. Maybe. Let me ask this, if there was a weed killer after 5 years taking into consideration reseeding, germination, buried seed etc., that weed killer would no longer be needed. Or as Ken said, "if someone shoots you and kills you - you are dead. You don't come back next year" why then do weeds come back next year and next year etc. but, we believe what they tell us and keep buying more (at least we used to) Maybe they just have a weed deterrent (a wounding - so to speak) now they can sell you more every year. Of course if they knew this they would tell you …. Wouldn't they. After all they have your best interest at heart. …. Just ask them.
For what it's worth ------ that's my opinion
