Planting and Care Tips for Astrophytum

Care Tips for Astrophytum

Potting soil: the root system is relatively shallow, so when potting, the body should not be buried too deep, and more tile pieces should be placed at the bottom of the pot for drainage. Use a mix of leaf mold and coarse sand for the potting soil, adding a small amount of bone meal and dried cow dung.

Fertilizing: keep the potting soil moist during the growing season, provide sufficient sunlight, and fertilize once a month or use a 15-15-30 special fertilizer for potted flowers.

Temperature: in winter the body enters dormancy, and the temperature should not be too high; 10°C is suitable. Keep the potting soil dry, and repot mature plants once every 3-4 years.

Propagation Methods for Astrophytum

Sowing: sow mature seeds by the end of April; the suitable germination temperature is 22-25°C, and they germinate 3-5 days after sowing.

Grafting: carried out in May-June, commonly using Hylocereus undatus or Echinopsis multiplex as rootstock, with seedlings or offsets as scions; after grafting they survive in 10-12 days and can bloom the following year.
