Blue eyed grass in a pot/

Zone 01467 | fred.publicmail@gmail.com added on April 6, 2017 | Answered

I potted my blue eye grass because it was being overwhelmed by crabgrass. It had been flowering in the years before that. It was one clump and made one flower the first year in the pot. It spread to fill the 15\" pot but didn\'t produce a single flower the second year. I am zone 6. It is wintering in my cellar. I am thinking of putting it back in the ground, but how do I defend against invasive crabgrass (without chemicals)? Or can I leave it in the pot, in which case how do I induce it to flower? The pot soil is rich with manure as I thought that might help keep the environment \"marshy\". Thank you.

Make sure you do not fertilize your Blue Eyed Grass. Too much Nitrogen will inhibit flowering. If the soil is very rich in compost, you can add some Bone Meal to increase phosphorous, this boost flowering. The plant may need to be divided. Lack of flowers can be an indicator of that.
Crab grass is a weed that frustrates many of us gardeners!

Hand pulling is the safest method. Perhaps if you lift the pot of rhizomes you can pull the crap grass from the soil more easily.
