I do think that fertilizing is part of seeing more increase, but I began fertilizing last year with uniform amounts and attention to all my daylilies. Most have just added a fan in the last year, or at most 2-3 fans, but some are nearly 20-times more fans than I started with in just six months! Way too fast for me to keep up with them. I wish there were a cultivar identifier that rated expected increase (sometimes called vigor when growers note it). I hate tossing otherwise lovely plants and flowers
Cindy, I've long admired Sabine Baur for many reasons, so thank you bunches, I will have to go ahead and bump it up to the top of my "to-buy" list!
