Why does my Brandy Punch marsh mallow hibiscus no longer have any flowers or new buds anywhere, as when I first got this plant it had multiple clusters? Please advise! Thank you.
Did you fertilize? If so, you may have given it too much nitrogen, which produces more foliage growth. Adding some phosphorus rich fertilizer or bone meal to the soil can help offset this. Also, what about light? Hibiscus needs plenty of light to promote blooming.
In addition, if you pruned too late, then this could attribute to the flowering delay. Maybe this article on pruning hibiscus will help: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/tips-for-pruning-hibiscus-plants-when-to-prune-hibiscus.htm
