How to get morning glory plants to thrive?

Question

What are the best nutrients for a morning glory plant in the northeast (Cleveland)?

Answer 1

Your morning glories will grow without fertilizer, but will produce more flowers and grow larger if you fertilize them monthly during the growing season. Choose an all-purpose fertilizer with equal amounts of nitrogen, phosphorus and potassium, indicated by a ratio on the label, such as 10-10-10.
