It was a very dry summer last year and we probably lost 3/4ths of our lawn to dead grass or crabgrass. Normally it's an uphill battle to get spring grass back in more than patches, but with a really wet spring so far and some different seed and techniques, the new grass has come in roaring.
1. Raked and surface shoveled out dead grass, crabgrass, moss, etc. Biggest pain in the ass here. Took me upwards of 20 hours, and was backbreaking at times in very stubborn patches of dead crabgrass. 2. Used Scott's 2x Rapid Grass this year. Expensive, but the results have been excellent. Or is it the rain? Can't be sure. 3. Covered with good quality top soil and raked through. 4. Watered every day unless it rained, which thankfully was almost half the days.
This is only a portion of the lawn, but as recently as early April, most of this and the rest of the lawn around the house was yellow, brown, dead, patchy. Some busting ass and a great spring for growth really did the trick.
Recently I went down the rabbit hole trying to research a top end battery powered weed whacker, as my two different (cheap) Black & Decker models are really frustrating. There are some Makitas I'm looking at that are as powerful as gas powered ones, but that price ($350+ with batteries/charger), whew! Any recommendations?
