Care:

Soil:
Star of Bethlehem likes loamy soil. Sharp soil drainage is key for healthy growth. In waterlogged soil, the bulbs can rot.
Water:
Young star of Bethlehem plants need regular watering to keep the soil evenly moist but not soggy. Mature plants have some tolerance for dry soil, but they still prefer a moderate amount of moisture. While the plant is actively growing in the spring and summer, water when the soil feels dry a couple inches down. When the plant is dormant, its moisture needs are diminished, and it typically doesn't need any supplemental watering. Stop watering when the foliage begins to turn yellow after the flowers are spent.
Temperature and Humidity:
Star of Bethlehem is quite hardy to the temperature extremes of its growing zones (4 to 9). Humidity also typically isn't an issue, as long as its soil moisture needs are met.
Fertilizer:
Star of Bethlehem flowers best when grown in rich soil. Mix some compost into the soil each spring to promote healthy growth. Additional fertilizing is not necessary, and may even hinder flowering.
Pruning:
After star of Bethlehem flowers finish blooming, you will be left with a mass of tangled foliage that isn't particularly attractive. However, resist the urge to remove that foliage. As long as it stays green, it will be feeding the bulbs through photosynthesis.
Overwintering:
Within its hardiness range (zones 4 to 9), star of Bethlehem is a sturdy plant that rarely succumbs to winter cold.
