SpringText Box: If you moved your plants to the deeper part of the pond for the winter, as soon as spring arrives you will want to move them back to where they were growing last summer. Do this as soon as the water temperatures have reached at least 55 degrees both day and night. Start feeding the plants and the fish at that time, as both will be hungry and need the food after the long winter’s dormancy. Spring is the best time to divide or propagate your plants.
