hair grass uprooting

[bennyp]

hi experts

I wonder if you have similar experience as I do.
My hairgrass, which has been growing for a year is beginning to uproot gradually.

When I try to pick up those uprooted hairgrass to replant them, it also remove along them - those rooted ones.

Is this a sign of some difficiency?
How do you guys reccommend I deal with this?

this is normal, the grass has grown onto the dirt it has trapped and no longer rooted in the substrate. can consider replanting or just hoping enough runners and rosettes remain in the gravel for the regrow.
