Z,
Two items.
1. Environment
2. Feeding

For me, when a plant is struggling to open blooms, it is environmental. Too hot, too much sun, lack of consistent watering. As each variety is different, like people, finding a happy balance can be difficult. Example is that all of my plants are indoors for the winter with a lower light, cool temps, and dry humidity. Some are blooming greatly, where others drop flowers before they open. I watch each of them and address their needs. Remember, all those leaves, and especially the blooms need fluids.

Next is feeding. Each variety and their situation needs to be monitored for nutrients. I have some that really enjoy a nutrient rich soil and I fertilize regularly. Others do not, and I watch for build ups of certain elements.

The goal is to find a happy balance for the plants.

hope this helps.
