Get rid of clover organically
The best way to remove clover from your lawn is to get the grass to replace it. With a little persistence and effort, getting rid of clover is entirely possible and can be done without the use of chemicals.
Depending how much clover has invaded your lawn, you could concentrate on a section at a time, but most urban lawns can be totally clover-free after a couple of seasons, some compost, topsoil and lots of grass seed.
Topsoil and perennial grass seed
In spring and again in the fall cover the section or patch of clover with a layer of topsoil and/or compost, then spread a healthy layer of a perennial grass seed mix. The best lawn grasses for Alberta are Kentucky bluegrass, perennial ryegrass and creeping red fescue. In spring when the grass seed germinates it will fight the clover and eventually reestablish itself giving you a clover-free lawn.
Weeds won’t stand up to boiling water
Another method of getting rid of clover in the lawn is to pour boiling water onto it. The clover will die instantly and some of the grass will also die but add a generous layer of new grass seed to the spot and when the grass recovers and the new seed germinates, little by little the grass will overtake the clover.
Reseeding the lawn in spring and fall works to eliminate not only clover but also the other weeds that appear out of nowhere and make themselves comfortable in your lawn.
