Take a break after flowering

After blooming, the star of Egypt needs a longer rest if it is to bloom again in the following year. Depending on the season, place the plant a little cooler for about eight weeks. Water only enough so that the root ball does not dry out completely. Do not fertilize during the resting phase.

  • Light location

Since the Star of Egypt is not hardy, in winter you need to put it in a place where temperatures do not drop below eight degrees. Ideal winter temperatures are between 10 and 15 degrees.

Make sure there is sufficient humidity during this time. If necessary, spray the leaves with water or set up open water bowls.

If the star of Egypt is in bloom, you must not spray the flowers with water.

Star of Egypt over summer outside

The Star of Egypt does not tolerate the cold, but in summer it appreciates a place outdoors. He then prefers a location that is airy and partially shaded. Direct sunlight, especially at lunchtime, does not do him well.

If you are maintaining a penta indoors in the summer, do not place it in a flower window facing south, as there is too much sunlight here.

In summer the temperatures should be around 20 degrees.
