Second post for me on this white bird of paradise, but I’m determined to save him. Water was running right through the soil in November, so fearing it was hydrophobic I submerged him for a bit. Now the water doesn’t run through but it appears to be failing. I water every 17 days during winter. Fertilize every 3 waterings. It’s in a 10” pot with drainage onto clay pebbles. Should I try repotting…has never been done. Should I separate the plants? Thanks in advance!
