Amaryllis Wax is a bulb covered in wax that provides all the nutrients to the plant, so it blooms without watering or planting.
The important thing is not to leave it in your house in a place where it will get too much direct sunlight, as the wax can be damaged or even melt.

My Amaryllis Wax has already bloomed, now what do I do?
Remove the flowers when they fade. Cut the stems to 1 inch (2.5 cm) from the bulb once the flowers have finished blooming, but don't remove the leaves. Sap may ooze through the cut stem, but it will stop soon after cutting.
After approximately three weeks, you can cut the wax with scissors and plant the bulb in a pot or in the ground.
Ideally, you can fertilize the bulb so that your Amaryllis blooms again.
