I had wonderful, big bloom marigolds in my greenhouse last year (several varieties from commercial seeds)
I saved the seeds and replanted them. Very few have produced flowers. About 90% have grown very big, look really healthy and lush but there are NO blossoms...or even buds. I found 2 or 3 that had small, stunted buds...less than a fourth the size that they should be. Do you think they cross-pollinated and are adversely affected? I thought cross-pollination might occur the SECOND year of seed saving...?
