Best option for a flagstone area to get grass or moss grow?

Research plants called stepables for you hardiness zone

Moss is wonderful, as it has a shallow root system, which would be nice with the ground you're talking about. You can buy it at garden centers.

My friend used yoghurt to grow moss in her flagstone patio. She first planted some sphagnum moss in a small area. Once established she took a basting brush and added plain greek yoghurt to her brush then rubbed the top of the moss. Gathering her basting brush she basically painted the area between the flagstones continually replenishing with the yoghurt. Although it didn't happen overnight the moss eventually started growing. It now has filled in and looks great.

I have also read that you can use Buttermilk.

I have moss growing between my patio pavers and I don't want it! Moss loves moisture and shade, so if you provide some of both, moss might start growing naturally. Good luck!

You don't have to mow moss!

Yes, moss!

Too funny. I'm trying to get rid of grass and moss (and weeds) that insist on coming up between my flag pavers!!!

Moss is nice looking, but as stated above , it has a shallow root system.

The moss can easily lift out with a dragged tennis shoe, or grand kids playing on the pavers!

TRy using Thyme between the pavers. IT is low growing and needs very little water once established. It smells wonderful. IN the summer it may attract bees though

if you decide you want moss, take some, put it in a blender with water and give it a spin, then pour the liquid "moss" (actually spores) on your scratched up dirt. The spores will start growing for you and replicating the original moss!! You get more coverage for your money!

The moss is beautiful - I have "voluntary" moss in the cracks of my concrete flagstone style walkway. BUT the area is mostly shaded. The moss is bright green and beautiful right now because it has been a wet Spring - but by mid summer, unless I constantly dampen the area, it will dry out and disappear with the heat. I imagine that in Texas that would be an issue unless your area is shaded and you can water it every day.

Unless it's an area that stays fairly moist (or that you can water frequently) you may have trouble getting moss to live. Like others have mentioned, it has shallow roots, so it dries out quickly. This might be a problem in Texas; it sure can be an issue here in North Carolina! Janet has the right idea: check to see what will thrive in your area.

how about thyme or mind your own bussiness or thrift.....

You might consider a sedum. They are fast growing and there are types that spread and grow out rather than up. You can also add a little bit of color. I am a big fan, as you may be able to tell. Go Sedum.

Don't do grass.....you'll have to cut it! Moss and thyme is the way to go.

I love moss. BUT the area must be shaded all day. If it is on the north side of the house it may work. My brother & I have even gotten creative and used several types of moss. Moss never needs mowing or trimming and you never have to worry about chopping it off too short. Yes, I think in Texas you still will need to water it often, even if in the shade, unless it tends to be a rainy area. Texas is so big, I think it must have a few different climates!

In texas, and considering the substrata, I'd consider Thyme, and Greek Oregano, both can withstand the heat, dry climate, stay small and smell great when crushed.. Stepped on...plus you can pick for cooking!

What a great idea! I will try a patch and see if I can keep it growing. Thanks for the idea.

Moss! You dont have to constantly cut it either!

Just a heads up. I tried Elfin Thyme, grass and moss, none worked. I had the flagstone laid about an inch apart so I COULD grow something but unfortunately the flagstone got too hot and burned anything I tried there. I'm in the north bay CA and the flagstone was in full sun to dappled sun, nothing worked. I ended up putting in fake grass. It took me quite a while to hand cut all the pieces but that was three years ago and I am so glad I did it now. No maintenance, weeding, watering and it looks pretty good!
