I didn't read through all of the posts in this thread this morning.....so this may already have been covered, but......
....but, what I have accidently, and pleasantly, discovered is that forage pearl millet makes a really great annual screen.
I bought a bag from Merit several years ago. I thought I was getting a 'seed'-producing version of pearl, but what I got was a forage variety.
....which meant I got a lot of 'cattail-looking plants, with minimal seeds. But the stuff got to be 7ft tall, thick, and it stayed upright all winter.
The following spring I just brush-hogged it and lit it afire.
To be sure, lit is an annual. Gotta do it every year. It looks like corn as it grows. And like corn it is nitrogen hungry. Now....and until I can find a supplier for a seed-producing variety of pearl, I will use the forage variety as a 'separator' row between various food plots, so it sort of 'compartmentalizes' my larger plots.
It is a vigorous grower, does suppress weeds to a fair degree....and can be sprayed with 2,4-D.
*btw, if anyone knows of a supplier of seed-producing pearl millet varieties, well, I'm all ears.
Here's a pic of a seed producing variety.
The forage variety looks similar....but the head is black, without seeds, and looks very much like a cattail head.
