Brown patches that form on your lawn are unsightly and ruin your best landscaping efforts. You can take some steps yourself to deal with the brown spots before you call a lawn care expert. Here are three ideas on how to get rid of dry areas on your lawn:
Do a lawn sprinkler audit
You should audit your lawn sprinklers to determine if the water sprinkled on your grass is sufficient. If your sprinklers are not working as they should, brown patches are likely to develop in areas experiencing water shortage. To carry out this audit, you will need to get some catch cups, place them in your garden and run the lawn sprinklers.
Measure the water that collects in the cups. If you have about 20 ml, then your lawn sprinklers are capable and will supply enough water to your grass over the expected two watering days each week. If the cups have less than 20 ml of water or none at all, you need to check your system for burst pipes or blocked, damaged sprinklers. Check out the way your nozzles are adjusted. As well, check if your pressure has changed. If it has changed, you might need to purchase other sprinklers.
Dry spots are mainly caused by a faulty sprinkler system and not pests as it's often thought. To get rid of bare spots, wetting the lawn is what is required, not a pesticide and fertiliser solution.
You will need to supply your lawn with a good quality wetting agent. The wetting agent is quite beneficial in maintaining the lush, and should be applied even during the rains. Applying the wetting agent when the season is wet is advantageous because the lawn remains damp and does not dry out, which would make it very difficult to wet. A wetting agent is applied two or three times during the rainy season.
Apply a fertiliser
Do this lightly, once in every six weeks. Applying fertiliser regularly every six weeks will make the grass green and healthy. Fertiliser application should be made gently since encouraging substantial growth flushes is not good for the health of the lawn. It stresses the plant when scalped.
Fertiliser application should keep the plant growing steadily and healthily. It should encourage a healthy lawn that will help the grass cope with stress from heat. As well, a well-fertilised garden will be healthy and able to resist diseases, pests and weeds.
As the grass thrives, mowing should be done regularly to the ideal height of 20 to 25mm.
