There is nothing like looking at a lovely weed-free lawn to put a smile on any gardeners face. The problem is that good growing conditions for grass is also good growing conditions for weeds.
There are some weeds that are so adept at survival that they can even make it through a good mowing by keeping their leaves below the level of the blade. I have no idea how they do it, just that it’s very annoying having to go back over the lawn and remove them afterwards.

Your lawn is a battleground between your grass and the weeds. They are both in competition for the moisture and nutrients of the ground as well as the space to grow. Many times though it seems the weeds have the edge when it comes to adapting to survive.

Fortunately you can tip the odds in your favour with a little knowledge and application. Not everyone is in favour of using weed killers. I tend to avoid using chemicals wherever possible, but I make an exception for my lawn.

There are two kinds of weed killer, the contact or systemic types. The contact type is generally in the form of a lawn sand and contains iron sulphate, nitrate sulphate and sand. This word by burning the weeds. Grass is tall and thin so the weed killer doesn’t stick to it, weeds are generally broadleaved and can support the sand.

Systemic weed killers concentrate on the differences between weeds and grass. Grass is a monocote and has a completely different growth clock to a weed, which is a dicote. A systemic weed killer concentrates its anger on dicotes and forces the weed to outgrow itself so much that it can’t support the growth and dies. To be most effective the grass has to be at least a few days without being mown, and the weeds should have enough leaf growth to suck all the energy out of the roots.

Soil Ph control can also help with weed prevention. Most lawn weeds like their earth around 6.5Ph but grass prefers a slightly lower 6Ph. This is how lawn feeds work, they lower the Ph of the ground thus feeding the grass and removing the weeds. If you feed your lawn, a little and often approach works here as it can regulate the soil and provide nutrients to recently mown grass.

If you want to remain completely chemical free then a watering program may help. Giving your lawn a good, thorough soaking once a week instead of having the sprinkler on a couple of hours a day will encourage the grass to push its roots deeper into the ground to acquire moisture. This leaves much less water for shallow rooted weeds and they simply can’t survive. This is also an effective method of keeping a healthy lawn in our lovely Naples sunshine.

These are just some of the ways you can prevent weeds from taking over your lawn. Some use chemicals and other don’t. Whichever method you use, if you follow the guide, you should be enjoying a weed free lawn in no time!
