Q. I have a very healthy Mucuna bennettii. When will it flower?

I have a very healthy Mucuna Bennetti. Two years old from a seed and in full sun in Miami.... my question, in which month it supposed to flower????


Answer

Your Mucuna bennettii plant needs to reach maturity before it will bloom. That is typically around two years old, so you may be in for some flowers soon.  After that, the most common reason for vines of this type to fail to bloom is enthusiastic pruning. It needs to be grown in a space where it can climb and expand to a large size and then be pruned lightly only just after blooming. If you are growing it outdoors in Miami, blooming should take place in late summer to fall.

Here are the other things that you can do to help it to bloom.

Make sure that the roots are getting some shade. If there is no natural shade available, use mulch to keep the roots cool and protected. The soil should be kept moist but never soggy. If you have your plant in a container rather than in the earth, make sure that the drain hole of the pot is not blocked and that soil is refreshed from time to time so that the texture continues to allow free drainage.

Beginning in mid-spring, feed your plant with a weak solution (half-strength) of high phosphorous, bloom-boosting fertilizer every two weeks. Keep going through flowering.
