Is there a way to level the ground under the grass now that it's established? Thanks, Dave I assume you mean you want to smooth the surface making it even, *not make it level. *Leveling (ie making horizontal) is hardly practical after you have laid sod. You could top dress it. *Using a friable loam, rake and drag it over the grass, cover thinly overall with almost none on the high spots but *filling up the hollows and cracks. A heavy log of wood pulled by a loop of rope will give you a smooth surface and in time muscles too! * The grass will grow through the dressing and form a smooth mat. *This is best done during the growing season otherwise you can get erosion down the hollows before the grass grows. David You're right and I probably did use the wrong term. I am interested in making the ground "even" (no hills or valleys), and hopefully with all of the tips I've gotten so far that will work. Thanks, Dave It would help to advise knowing the size of the area.- Hide quoted text - - Show quoted text - It's a little bigger than 15 feet by 25 feet. Dave It's small enough that you can even your lawn yourself with a hand pushed roller... you can probably rent one but I think it's best to have your own as you will likely need to roll your lawn a few times each year: *http://tinyurl.com/ycrrapq http://www.amazon.com/Agri-Fab-18-In...5-0267/dp/B000... So would I just soak the ground to soften it up and then roll it? Or is there anything special I need to do first? Thanks, Dave Rolling compacts the soil. So you solve one problem for another. One would thinks so but rolling does not compact soil, in fact it does just the opposite, in flattening the ground rolling redistributes soil particles making soil more porous thereby increasing its volume To a degree rolling aerates (however not in a good way). To compact a vibratory machine is used, which forces particles to interlock in such a way that makes the soil more dense and lessens its volume. When rolling lawns one needs to be careful not to roll with too much weight and make too many passes or the soil will become so fluffy that it breaks contact with the grass roots. Same when one mows close around trees, it's best to use a push mower rather than a heavy garden tractor. Landscapers and grounds keepers use rollers all the time, in fact when mowing athletic fields/golf courses the anti scalping rollers are adjusted to apply enough pressure to flatten the ruts made by mower tires. Road builders use rollers to compact, but they are very heavy (tons) and they vibrate... they're used to compact the roadway sub base of crushed stone and the blacktop, not garden soil. Vibrators won't compact good organic garden soil... if your soil compacts from rolling then it's very poor quality soil for growing a lawn (or anything) and needs substantial ammending.... like how experienced farmers can judge soil quality by grabbing a fistful and and applying pressure, if it all clumps together it's not good farmland... good arable farmland won't compact. |
