De-Thatching New Lawn
Comments (1)Rick....I'm certainly not an expert but it sure doesn't sound like a thatch problem to me. More likely some of the new growth didn't make it through the winter. What type of grass did you seed with last summer? Pics (if possible) would certainly help the very knowledgeable forum members (I'm not one of them) make a very good diagnosis with recommendations to you.......See MoreCan I de-thatch in July (NE Indiana)
Comments (1)You can dethatch in July, but that doesn't mean you should. Grass is already stressed in July due to the climate and dethatching stresses it further. You're better off dethatching in cooler weather, either spring or fall. You want to do it while the grass is growing, so it can recuperate, but it should not be when it is too hot and dry....See MoreDe-thatching
Comments (10)Be very careful using those power rake machines, if there're not set properly they will tear up your lawn in no time. Most lawns are not perfectly even like golf putting greens, so when yo go over with the verticutter or power rake, you can easely dig/damage the soil surface and many grass plants in the process. Thatch consist of many layers of undecayed grass between the soil the grass plants. Thatch is primarily composed of roots, rhizomes, and stolons; and NOT grass clippings like most people think. Thatch formation is a natural part of the growing cycle, in which grass plants age, die, and decompose. The problem occurs when something upsets this natural balance causing thatch to build up quicker than it can break down. Excessive lawn growth is the major cause, and over fertilizing and over-watering are the biggest culprits. They produce excessive amounts of grass clippings preventing the normal/natural breakdown of thatch. Of the cool season grasses, Perennial Ryegrass and most Fescues produce little to no thatch, Bluegrasses and Bentgrasses produce the most. Warm season grasses produce the most thatch, with Zoysia being the worst. I have used the power blade mower attachments with great success, however, it killed half the lawn in the process. I didn't matter to me because I was overseeding with a different type of grass, your case might be different. You are up in Indiana, so you must likely have a Kentucky Bluegrass, which if over watered and over fertilized it will produce excessive amounts of thatch - specially if you live in an area that gets plenty of rain during the growing season. My advice to you is to Aereate the heck out the lawn, then topdress with Humus. Then change your fertilizing schedule to 3 to 4 feedings per year max with at least one organic application instead of synthetic man-made. I hope it helps.

Comments (2)Results for seeding are almost always in line with soil prep efforts. TF does not build a thatch layer as it tillers and does not rhyzome (root spread). The 'thatch' you see is likely to be dried, mown grass clippings which will decompose much easier than a thatch layer will. Still, anything between seed and loosened soil will reduce soil contact and lessen germination. You are looking to make nooks and crannies (like the inside of an English muffin only on a smaller scale). The seed then nestles in, 1st watering covers seed with a thin film of soil. Keep that first 1'4" of soil moist for as short as a week (Ryes) and as long as 3 weeks (KY blues) and VOILA! Once seed germinates completely (mixes can take as long as 3 weeks as suggested above) allow for heavier and more infrequent watering to keep seedbed watered to a greater depth (new grasses do not have a lot of roots yet). In the Fall, there is always a point where cool, wet weather makes watering moot....See Morestripped_threads
