Why Doesn't My Bittersweet Vine Blossom?

Sunlight
-
Although the American Bittersweet vine receives its nutrients from minerals in the soil, sunlight plays a vital role in the development of flowers. American Bittersweet can tolerant some shade, but too much will stress the plant, causing it to expend its energy on staying alive at the expense of flowering.
Weather
-
The American Bittersweet vine produces flowers in the spring, with the buds forming earlier. A late freeze can destroy the tender buds before they bloom and eliminate most or all of the flowers for the year.

Nutrients
-
Not all soils are created equal. According to the U.S. Department of Agriculture, the American Bittersweet vine requires a medium amount of fertilizer to thrive. If the soil is lacking, your vine may not have the energy it needs to produce flowers. Consequently, too much nitrogen in the soil will cause the vine to concentrate on leaf formation at the expense of flowers.
Only Female Cultivars
-
The American Bittersweet vine has male and female plants. Both of these types of vine are necessary for the plants to produce flowers. One male plant will pollinate several female plants. Without the presence of a male, the female plants will not produce flowers.
