Anyone with Big Blue experience.

[BC Buck]

In 2009 planted Big Blue in mono culture for visual screen. Under drought does not produce seed heads and only gets about 18" tall. My row of CIR along side of it reaches 4' every year. On average years 30 to 50% will produce 5' seed head. 100% of seed head falls over by December. This grass is a very thick stand. My Big Blue in the CRP is in small clumps and over 50% will stand most of the winter.

Was thinking stand was so thick might be stressed for moisture and nutrients. If that is the case wood running boom sprayer over with every other nozzle blocked applying glyphosate to thin help.

I don't like warm season grass as a screen.
It doesn't seen be thick enough even if it gars tall.

Look into a row of Miscanthus grass. I think you would be much happier.

For the ? At hand. I'd try fertilizer over killing what you have.
