If Ornithogalum is cultivated as a potted plant, water it regularly so that the soil never dries out completely. But avoid waterlogging, as this will cause the onions to rot.

Do you need to fertilize a milk star?

If you add some ripe compost to the planting sites before planting, there is no need to fertilize the garden bed.

For maintenance in pots, give some liquid fertilizer every two weeks before and during the flowering period. If the milk star has faded, you must no longer fertilize.

Is ornithogalum cut?

Cutting is not necessary. You can cut off the faded inflorescences if you want to prevent the plant from multiplying itself.

You should never cut the leaves of the milk star. They will move in by themselves after a few weeks anyway.

Do you have to watch out for diseases and pests?

Diseases will only occur if you care for the plant incorrectly. Usually too much moisture is responsible for rotten roots.

Occasionally, aphids infest the milk stars, especially if they are grown in the tub. Rinse the lice off with water.

How do you care for ornithogalum in winter?

Frost-hardy varieties do not need special winter protection. But you are welcome to sprinkle some brushwood or leaves over the planting site before the onset of frost.

Frost-sensitive varieties are removed from the pot as soon as the leaves have pulled in. Take the tubers out of the ground, shake them well and then let them dry. Store the onions in wood shavings or paper bags in a dark, frost-free place.


When ornithogalum blooms depends on the variety. Some varieties bloom in spring, others in summer and fall. Not hardy milk star like Ornithogalum dubium has its flowering time in winter.
