I bought a hyacinth at the grocery store in a water-only pot with the bulb suspended over the water.
The flowers have now died, and the roots have started to break off of the bulb, although there are a few new roots coming out.
I noticed this question about hyacinths, but it wasn't clear they were talking about this setup. Since I live in an apartment, I'd rather keep the bulb in a pot if possible.
What is the best way forward for this plant?
