Brown Patches In Lawn: Common Causes And Prevention For A Healthy Lawn (part 3)

❌Improper Mowing

Important factors in mowing the grass lawn include the height and frequency of mowing. In case your lawn is infrequent of being mowed, it requires a deeper cut to reach a proper height. However, if your mower blades are sharp and you begin to cut your grass too short, it can cause stress on the lawn ground and create some brown spots. Always remember to keep your mower blades cut no more than a third of the grass blades.

❌Too Much Water/Fertilizer
Overwatering and underwatering are both common causes of brown patch disease. While underwatering creates a drought condition for soil, too much watering can lead to saturated soil conditions. Although most grass can tolerate drought conditions for a while, they will leave brown spots onto the ground, or even die through extended periods of high temperatures in late summer.
However, overwatering will suffocate the grass and weak the roots. Ideally, lawns need watering averaging one inch of water per week, including either rainfall or irrigation.
Besides, over-fertilization will leave your lawn excessive nitrogen that causes unwanted brown spots. There is a recommendation of professional lawn care not to add fertilizer on hot days to easily do weed control.
