The temperature is considered the central control instrument for the growth and flowering of an amaryllis. A subtropical bulbous plant, a knight star thrives on a reverse vegetative cycle, centered on a sunny, rainy flowering and growing period, followed by a dark dormant period. You can read here which temperature is obligatory in each case.
Amaryllis like it warm during flowering
This temperature level suits the Knight Star
In order to get the optimum out of a hippeastrum, the thermometer should be in view at the respective location. Amaryllis wants these temperatures:
- During the winter flowering period (usually from December to February): 18 to 22 degrees Celsius
- During the summer growth period (usually from March to August): normal summer temperatures, preferably 20 to 28 degrees Celsius
- During the autumnal rest phase (usually from September to November): 5 to 9 degrees Celsius
Please keep in mind that a knight star is not hardy. If the mercury column falls below 5 degrees Celsius, you are depriving yourself of the magnificent winter blossoms.
