Meaning

Staying true, courage

Thorns all over, and little red flowers. Drought-tolerant and easy.

The white sap is poisonous, and the thorns stick. People, cats, and dogs all need to be careful.

Light

Plenty of sun

Water

Water thoroughly when bone-dry

Temperature

15-32°C, not below 10°C

Feed

Once a month in spring and summer

Do this when you get home

  1. Put it on the sunniest windowsill
  2. Water only when the soil is bone-dry. Drier is safer than wetter.

Day to day

  • More sun means more flowers
  • The white sap that runs when you prune is poisonous. Wear gloves.

Common questions

All the leaves dropped?

Winter was too cold, or you watered too much. Move it somewhere warmer and hold back water.
