How do I fix my lawn that has been cut too short?
If you have been cutting your grass too short, you can try to repair the damage that was caused. First, let your grass grow back gradually to its proper height and never remove more than a third of the blade length at any time. You may want to water deeply through proper irrigation to help your lawn recover.
Areas where grass blades were cut too short will usually recover slowly, but the brown patches may be evidence that you cut into the crown (growing point) of some grass plants and killed them. If the dead patches are no more than a few inches in diameter, grass regrowth may fill in the bare spots.
Shorter lawns means shorter blades of grass, and the less blades of grass, the less photosynthesis, which means a whole lot less roots and shoots. It's science, man. And that's from cutting it less than a couple of inches.
When cutting the grass you should always follow the one third rule. Never cut more than a third of the blade of grass off in one go. Cutting more than this will stress the grass. Grass that turns yellow or brown can be a tell-tale sign that the grass may have been cut too short or overly stressed.
One of the reasons KBG became so popular in Europe and then North America is because it can recover from over-grazing better than most grasses. Over-grazing is similar to close mowing. Your lawn should recover within a week or so if you water it.
After scalping your lawn, apply with fertiliser and water well for the following 2-3 weeks. It is best to perform this method in spring when your lawn will recover the quickest. For that, you want a quality fertiliser such as Lawn Solutions Premium Lawn Fertiliser.
Updated July 22, 2022. Depending on the turf species, it can take anywhere between five and 30 days for grass seed germination to begin. After that, it takes another three to four weeks before the grass is long enough to mow.
Scalping will remove dead grass, buildup, thatch, and debris and help the soil to warm up faster. Faster soil warm-up means the green, new growth will occur sooner rather than later (and make your neighbors jealous).
Generally, this takes 3-4 weeks, depending on the season. How long after sowing grass seed can you mow? Grass seed when it first sprouts has very fine and delicate grass blades and shallow root systems. You need to wait until your grass is established, which may take up to 2 months depending on the season.
Mowing your lawn too short is a bad idea!
your lawn doesn't have the same grass as a bowling green or golf course! Highly manicured greens (what lawn experts call 'fine turf') will be sown using a highly specialised cultivar of grass. It is developed to specifically tolerate very regular, close mowing.
Is it better to cut lawn short or long?
Mowing too short or scalping results in stress to the grass plant. Weak grass plants will take longer to recover. To maintain a 3-inch lawn, mow before the grass reaches 4.5 inches tall. Mowing too short can allow weed seeds to get more sun and increase the chance of germination.
Brown spots that appear after mowing are often caused by a dull mower blade. Dull blades will shred the grass instead of cutting it cleanly and will damage the ends. This causes the tips of the grass to die and turn brown. You can easily fix this by sharpening or replacing the blades on your mower.

Raking for New Growth
Dead grass should be raked away, but it won't stimulate growth, because if the grass is completely dead all the way to the roots, it can't produce new growth and the bare patch will remain. To fill in the bare spot, you'll have to prepare the area for reseeding or laying new sod.
The common types of lawn grass, including zoysia, fescue, and ryegrass, will only grow about 1/10 of an inch a day in their growing seasons. If conditions are just right, this rate can double to about 1/5 of an inch per day.
When mowing, take care not to cut the grass too short as this will stress the grass reducing its vigour and encouraging moss.
- For a typical residential Midwest lawn, maintain a height of 3 inches or higher. Taller grass shades out weed seeds and keeps soil cooler. ...
- Remove no more than 1/3 of the leaf tissue when you mow. Mowing too short or scalping results in stress to the grass plant.
