You don't say where you are or what are your growing conditions. Folks here on the forum are usually willing to offer ideas for problem solutions but they can't do that unless you describe what's happening in more detail. Simply describing your soil/moisture conditions is normally sufficient for folks to comment on/offer suggestions to mitigate your problem. I have no problem with stating I'm in southern New England Zone 6 + my soil is slightly acidic sandy loam.

Plants generally know what to do assuming they're planted in soil they like. I don't grow liriope since it doesn't meet my gardening goals/expectations. I garden to sustain pollinators (bees, butterflies & hummingbirds).

It's generally accepted that plants need to be planted at the same depth you buy/grow them in pots but what's not explained is that nursery-grown plants are generally pot-bound with their roots circling the container. I routinely "tease" the pot-bound roots until they're loose enough to grow down into the soil where I plant them.

If you're serious about growing perennials, check out 'The Well-Tended Perennial Garden' from your local library.

Yes - we really need to know where you are and also a picture of the problem would be helpful. Liriope is pretty tough and in many climates it would need no watering at all.

Northern Mississippi.

I will try to take pics later today

does the wall face south ... if not.. which direction??

were they planted this spring or last year??

you should water.. when a plant needs water .. insert finger and find out ... let near dry before watering again ...

Lirope is a plant typically used around here in places so dry, hostile or shady that nothing else will grow, like under dense trees where theres a lot of roots in dry shade. I wish I could get rid of whats invading my yard on the east side from the neighbors thick mess of it, actually nothing can get rid of it except manually digging it out, roundup won't even faze it, it'll kill off the tops but the roots just laugh. It even stands up to extended periods of drought with summers of 100 degree days for weeks and no irrigation all summer long. The tops shrivel up and look bad but the roots are fine. Any little piece of root left in the ground will sprout a new one, they spread via fleshy underground roots forming colonies, the roots are tenacious and will travel through hard clay or a barrier if there's any little crack and its hard to get rid of. I believe a completely buried lirope plant might die off on top but its roots would still grow and I'd even venture to guess one planted upside down would take off or if you just buried some roots in the ground, those would grow too. So, planting too deep isn't a problem.

Point is, you don't need to molly coddle it.

the white stuff all around the plants is cornmeal. I had read putting cornmeal around the plants and mixing some into the soil might help the crown rot problem. It was worth a shot....

first pic is of the wall. the liriopes are on the other side along the wood wall.

Did the cornmeal fix work?
