Brown grass is not what you intended to grow when you sowed all those grass seeds, yet that’s the current colour of your lawn. Turning your brown lawn green again can be done, but it will be a process that will take a little time, effort and maybe a little help from a garden maintenance company. Lawn care is a rewarding task that will improve the curb appeal of your home and also its value. Follow these tips to help discover why your lawn is brown and how to turn it back to a lush shade of green.
What’s the Problem?The first step is to discover what has caused your lawn to turn brown in the first place. The underlying reason may be dehydration, improper mowing, disease or pests, and until you find out what the problem is you will not be able to fix it.
DehydrationTo determine if the problem is dehydration, identify the exact type of grass you have and the amount of water it needs. Next, place four empty cans or jars at the four corners of the lawn and turn on the irrigation system for 20 minutes. Measure the amount of water collected in the cans/jars to see if the water amount is sufficient and if the lawn is receiving uniform amounts. Make adjustments to the irrigation system if needed to ensure your lawn is receiving adequate hydration.
PetsDoes the lawn have a few brown spots within healthy green areas? The problem is most likely dog urine.
Chemical BurnIt could also be caused from fertiliser burn or improper mowing. Applying too much fertiliser, herbicide or any other chemical in one spot will burn grass and turn it brown. If your lawn mower has a dull blade it will rip grass up by the roots instead of cutting off the tops and create brown spots in the lawn. Sharpen you lawnmower blades at the end of each cutting session. To restore healthy, green growing grass to the brown spot you will first have to flush the area with water to remove the irritant. Run the water hose on the brown spots until they are saturated, then allow the water to seep into soil overnight. Repeat the process on the second day. The water will dilute the irritant and remove it from the grass roots. After the area(s) has been cleansed it can be re-seeded at the right time of year, which will be spring or autumn. Making the switch from chemical food and treatments to organic products can also help prevent browning and keep the grass green and growing. Organic products are better for the environment too.
Disease & FungiDiseases leave behind behind different identifying trademarks, but all will turn your lawn brown. Most lawn diseases are of the fungal variety and they take on differing forms; some leave thin brown lines of dead grass across the lawn, some leave rings, other fungi leave behind slime. The more common fungi are:
- Dollar Spot, which are small, round brown spots that spring up on cool, dew-filled nights
- Brown Patch attacks turf during hot, humid weather
- Fusarium Blight that attacks grass blades during times of hot, dry weather.
