Ponds 12, 9’ x 2.5’ blue poly tanks Filled with ~1 cu. yard of 50/50 Pine bark:clay loam Respective fertilizers applied at 1 lb. N per tank
Lessons learned from EV Smith Containment: No chance of overflowing into each other Dividers cut to size Overflow pipe: Maintain water level
Issues Dividers had to be anchored with cinder blocks Some lotus were growing well & others were not: Contribute to too high of N concentration for organic fertilizers
Resolve:Dug out ¼ cu yard & mixed in fresh substrate Lowered [N] to .75 lbs N per pondRemoved dividers & replanted ‘E 2’ June 2010 Photos taken 13 July 2010 ‘E 2’ lotus grown in conventional slow-release 16-6-12
