Grass Won’t Grow? Here Are Three Reasons Why

When your lawn isn’t growing like it should be, it can be exasperating. Here are three of the most common issues I encounter with my clients:

Lack of Sun

One of the top reasons for a lack of growth is a lack of sunlight. This may seem obvious, but the challenge is in fixing it. When a lawn sees an awful lot of heavy shade, it can be difficult to find a solution and get it some much needed solar energy.

Many of the most common types of grass in South Florida needs at least four hours of direct sunlight each day in order to grow properly. This varies according to the specific species of grass, of course, so feel free to give me a call if you have a specific question.

If your lawn doesn’t get a lot of direct sunlight, there are strains of grass here in Miami that can thrive in the shade. There are also other types of ground cover that can be used in place of lawn, so sometimes the best option is to simply give up the idea of having a “traditional” lawn and move to another form of outdoor décor. This can also save you money on your water bill!

Too Little Water… or Too Much

Too little water is obviously a problem… but so is too much.

Your lawn needs water to grow, but the trick is in knowing how much water your lawn requires. Overwatering can be just as perilous to your grass’ welfare as a lack of water, stunting growth and resulting in shallow roots. I’ve personally seen plenty of well-meaning homeowners overwatering their grass and keeping it from developing properly.

Some lawn owners water often but they don’t water deep enough, leaving the roots out of water exposure range and simply grazing the tops of the grass blades. Sometimes, the rain provides more than enough water to keep your lawn healthy—but oftentimes regular watering is necessary.

Cutting Too Short

A final reason as to why grass won’t grow is that it is being cut too short.

Ideally, blades of grass shouldn’t be cut by more than 30 percent each time the lawn is mowed. If more of the lawn is cut, the roots can actually go into “shock” and may not produce growth for a couple of weeks. Some grass that is cut too short or snipped too close may stop growing for a month or more. Because the grass is more exposed, it is probable that other problems – like weeds – could take over and ruin the yard.
