I have six calla lily plants in my flower garden that I planted two or more years ago. Only one has bloomed this year, producing one flower and the leaves are very long and tall. The others are small and not producing. If they need more sunlight, can they be transplanted now in the summer, or do I have to wait until the fall? The one that has bloomed produced one flower, the stem is tall, and it has very large leaves. Do you think it has too much nitrogen?

Yes, it could be too much nitrogen. You can counteract this by adding some phosphorus rich fertilizer or bone meal to the soil.
