Indoor Bird Of Paradise Leaves Splitting And Only Partially Unfurling
I have what appears to be a thriving (very tall and broad) indoor BOP plant but as it emits new leaves the majority of them split and only partially unfurl. I have three leaves now with unfurled points on them. I have read recommendations to spray them with light soapy water to loosen any gunk causing them to stick along with an increase in water. Is this correct and/or are there other suggestions to get them to open. They look very odd to say the least.

It can help to do so, but this is caused by a lack of humidity.
You will need to bring the humidity in the area up, way higher, than a typical house would be. A humidifier can help, drastically. A low tech method would be adding a tray filled with pebbles and water under the plant.
