Was just poking around in my container ponds and noticed that Bull's Eye, Lindsey Woods, and Ostara have all sprouted (Ultra Violet tuber was firm, no growth yet)! I kept these guys just a few inches from the surface over the winter...and we had some intense winter weather, with 4-5 days with high temps below freezing. These containers had solid ice for the top few inches for days at a time.
P.S. Bottom drain plumbing was finished two weeks ago, skimmer is nearly set, and I hope to have the liner in before the end of spring break.
Ponding life is good!
