Q.Akebia won’t bloom
I have an Akebia trifoliata, chocolate vine. It’s three years old. It bloomed the first year, fewer blooms the second year. . . no blooms at all the third year. Plenty of foliage, but no flowers. It’s in full sun, on a south wall, growing on an arbor. It’s about 12′ long/tall. Any suggestions?
Thanks,
Long Island, New York

You may be lacking phosphorus. If there is a lack of phosphorus in the soil, plants will have little to no blooms. You can either use a phosphorus rich fertilizer or add some bone meal to the soil. This article may help as well:
