Ipomoea alba 25' and not flowers?
My 4 vines were planted from seed in mid-April in a 14" pot. They get several hours of direct sun and several of filtered sun on a hot deck...temps often in the 90s. They grow up bamboo stakes and in to my ash tree and are now app. 25' long, with the first 15' being vertical and the last partly horizontal. i did not pinch them and they don't have any side branching. NO hint of buds yet, but some new leaves forming in the leaf axles. I water them every day and have not fertilized except for the pelleted, time released fert I mixed in with the potting soil when I planted the seeds. Is there anything I can do to encourage bloom or is it just a matter of time if I keep my fingers crossed? Thanks! Wobur
