Carolyn - Yes! Lotus for me are actually heavier feeders than Waterlilies. I can add a pond tab to a waterlily and go more than a month without feeding them again without seeing too drastic of a change. But with Lotus, the aerial pads will start to turn brown and the plant will decline as if going into dormancy. I've learned through trial and error that they need monthly fertilizing throughout the warm months to continue to show their beautiful growth and to bloom.
