Learn how to grow amaryllis bulbs to liven up your winter home with color. Place the container in a location where the temperature stays above 60 degrees Fahrenheit and the sun shines brightly, comparable to a south-facing window with a lot of daylight. The hotter the temperature is, with 70 to 75 degrees for day and nite time being perfect, the sooner the bulb will start rising. Offering backside warmth by setting the pot on a propagation mat might help stimulate development, particularly if you maintain your own home temperatures cool.
