Shave lawn as close to roots as possible.
These are tips on lawn repair because even the most cared-for lawns sometimes need extra attention.
Shaving a lawn down to the roots is the best way to get rid of problems. If you have a lawn mower that is powerful enough, it will take only a couple of passes with the blade set to the lowest point to get it down. However, electric mowers have less power and will need to have the blades lowered continually until you can cut it low enough.
After the lawn is shaved, loosen the dirt around the roots with a pronged garden tool such as a pitchfork. Next, loosen the roots with the same tool. Spray the lawn with Jerry Baker’s fabulous, organic formulas (see link in resources section). Re-seed the area with high quality lawn seed and then apply seed cover. Water well and keep area moist until the lawn seed sprouts.
Brown spots in a lawn might mean there is a grub problem. Pull up a dead spot. If you find a fat, white worm curled up underneath, that is a Japanese beetle. They have eaten the roots and caused the brown patch. Milky Spore is a product specifically used to rid lawns of this problem. The grub eats it and dies which causes the Milky Spore to spread throughout the area. Once it has spread, your lawn is protected for 15 years. Applying it is easy if you purchase the tube applicator, which come with complete instructions.
Pets and stray animals also cause brown spots. Their urine and feces are so acidic it will kill grass and plants. Use an organic and humane product like CatAway that is safe for both people and animals. Treatment of brown areas in the lawn is a very easy. Simply pull up any dead grass and their roots. Apply a high quality grass seed, a little fertilizer and seed cover. Water well. Apply the formula in step 2.
If your area is prone to drought, cut down on fertilizer and water your lawn deeply at least once per week. Deeper, longer watering will keep the roots moist. Shallow watering only wastes water and your lawn will die because the roots become dry. Using a pronged tool, put holes in your lawn (aerate) so that the water can penetrate. I used to walk on my lawn in a pair of old high heeled shoes. Of course, there are special tools made for aerating but you can use anything that works well.
You notice, after a rain, a lawn stays green for quite some time, even in our drought-prone area. That is because moisture has reached way down to the vital roots. Try to simulate that when watering.
