How to grow grass in shady spots and under trees

“We spent $3k on sod installation last year and clearly it did not last.”source ↗

“Bought this house last September and there was a 6 inch layer of leaves covering the entire back yard. Once I got it all cleaned up I tried planting grass (Zoysia since it’s so shady) with very little success.”source ↗

“We will definitely need new soil on top of the existing stuff, juat wanted to see if grass was possible any radius away from the trunk.”source ↗

“Every time the Navimow goes down this side of the house I wonder why I'm even keeping grass here lol. It's narrow, shaded, nobody uses it, and somehow it still counts as part of the lawn.”source ↗

“Starting to think I should just give up on the grass and turn the whole strip into something lower maintenance.”source ↗

“Oaks and shade you're basically playing on hard mode, especially with that clay. Sod never stood a chance under those trees, they suck all the moisture and the canopy blocks too much light.”source ↗

“Forget grass in the deep shade, it will always thin out.”source ↗

“Since then, the areas that get full sun have really taken off (third pic) but the areas that get more shade this time of year are coming in a lot slower.”source ↗

“Should I just wait it out and continue watering or throw a little more seed down on the patchy spots?”source ↗

“I’m tearing down my old lawn and going to put up irrigation. Was wondering if this grass seed is really good as it claims it is, I also only get around 4-6 hours of sun on some parts of lawn.”source ↗

“portion of the grass nearest our fence is dead and won’t come back.”source ↗

“I realized from using a sun app, we planted grass on the side of the patio that mostly does not get direct sunlight and when we swing into winter, it gets even less sun.”source ↗

“I am very new to lawncare and would love some advice!!”source ↗

“Im making headway on the crabgrass but now I have a bare spot under the tree.”source ↗

“I would love to get some more grass under that tree.”source ↗

“the back part of the yard is a big ole pine tree that causes a shadow spot where really nothing grows save for a handful of weeds.”source ↗

“I’ve read covering the roots of the tree with top soil could potentially kill the tree. Is that accurate?”source ↗

“Unfortunately, the previous owner let this tree get really bushy and it killed all the grass below it. The top soil is really thin and the roots are exposed.”source ↗

“We just mulched around the tree relatively recently, but I want to get the grass fully growing again.”source ↗

“I looked up the bag and the PDF and it tells you jackshit about what cultivar and ratios.”source ↗

“I have this large bare patch in my lawn that I'd really like to get grass growing in. It's in Southeast Michigan and gets quite a bit of shade from the surrounding trees.”source ↗

“Earlier this year, in late spring, I raked the area thoroughly and cleared out all the leaves and debris. I then spread grass seed that I bought from Lowe's and watered it, but unfortunately almost nothing grew in this area.”source ↗

“All the other houses in the neighborhood have bright green grass in their yards while ours looks barren.”source ↗

“I think it’s clear the tree in the front yard is a big contributor to this, but I was wondering if there was anything I could do to make it look better.”source ↗

“I bought this house 1 year ago with a lawn, and it died within the year and it’s left me with this…”source ↗

“During peak summer I probably get 90% shade coverage across my entire yard so I’m wondering if there’s any way I can get a lawn for next year.”source ↗

“Obviously the ground is very dense and I’m willing to rent an aerator, but only if it would benefit me.”source ↗
