Last year my new duranta had purple flowers and yellow berries at the same time, a quality I love. This year the plant looks healthy, but has only flowers, no berries. Why not? How can I encourage berries? Thanks!
It would be good to fertilize once a year with a balanced, all-purpose fertilizer. It could be lacking in potassium and phosphorus. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/flowers/duranta/care-of-duranta-plants.htm
