Thank you for the quick replies. I will need to order some plants. I would guess that getting the plants in the Spring would make the best sense? My lake is 20 acres so I just would like to get something started that might last long enough to spread. The chara that used to be in the lake would grow in water up to 10 feet deep and was rather problematic when trying to fish with plastics or anything that could reach the bottom. I add between 30-40 Christmas trees each year to give the small bait fish a fighting chance.
