Q.My plant is not in water or soil, but a green moss. What do I do?
I bought it at Costco and it is flowering, but it has no water or soil, just this green moss like substance. Came with no directions. I put a piece of the green stuff outside on board in front of flowers .

These bulbs have been "forced" to flower right off... This is something that many plants cannot recover from, and will die shortly after.
Fortunately, the Amaryllis you have is well adapted to forcing. It will grow just fine. This article will give you more information on what to do from here: https://www.gardeningknowhow.com/ornamental/bulbs/bgen/how-to-plant-a-flower-bulb-in-your-garden-after-winter-forcing.htm
