Outdoor Pond StudySpring/Summer 2010
Ponds12, 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
Overflow pipe:
Maintain water level
Dividers cut to size
Containment:
No chance of overflowing into each
other
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
