sunflowers and underseeding clover
Has anyone ever planted sunflowers and underseeded them with clover? I know this is common with corn, but I would like to experiment with suns.
I would plant the sun seeds, then, after the 1st cultivation, when the suns are a few inches high, spread the clover seeds.
The benefits I see are:
1. Provide some nitrogen to the suns. (I know they need some, but would it be too much to prevent good flowering?)
2. Eliminate any more weeding between the suns.
3. Cover crop would already be in place after the harvest of all the suns. Which could be tilled in for a new crop, or left to overwinter.
The main concern I have is the underseeded cover crop competing with the suns for moisture, nutrients. I know that the very 1st sunflower bed I planted, I did not weed it at all. The result: Tiny, stunted suns. Every time thereafter I meticulously weeded the beds and the suns were tall, stocky and beautiful. Would the cover crop have the same negative effect on the suns as the grass/weeds did?
Thanks for any info. or comments!
