I've planted Sunflowers in the past - I tried them for deer - and while I liked them for small game - they did nothing for me as far as deer go. Still sunflowers are fun, colorful and can work with corn.
This year on a very wet section of corn I planted, I tossed a pound of sunflower seeds (birdseed actually)on the plot after the Roundup Sraying in July. They grew - but could have benefited from Nitrogen - and/or less rain.
The flowers aren't huge - but the plot is nice to look at!
If doves were legal in NY - I could really enjoy plantinga serious sunflower plot - but - as it is its easy andjust for fun.
