SRG summer planting, trimming tops?

cactusgardenJune 18, 2011

I think I need to trim back the tops of the Little Bluestem I purchased. I am positive I read once to do this if you are summer planting new O. grasses but would like a second opinion. Seems I read to trim back the tops 1/3 or 2/3 (which?) to encourage thicker plants and stimulate root growth and to take stress off the young plants helping them establish, but cannot remember exactly. These plants have culms on them and look fairly scraggly as a result, but healthy otherwise, with no die off. I am giving them a good watering every day and they are planted in good loam that takes up water well and drains fast.

Some cold season grasses will respond to in-season shearing by sending up new growth. Carex muskingumensis and Festuca glauca are among them.

Warm season grasses, however, like S. scoparium, are finished growing new shoots until next year. The existing shoots will elongate until the plant starts to flower, and if you trim the blades, they will have squared-off blades which will brown at the edges.

My experience is that bluestem will put on a push in its growth in late August and september into its October bloom cycle. I seems like if you trim it a bit, it will have time before it is ready to push out its blossom.
