Rebutia is a genus of flowering plants in the family Cactaceae, native to Bolivia and Argentina. The limits of the genus have varied widely, depending on whether genera such as Aylostera and Weingartia are included or treated separately. As of December 2024, Plants of the World Online accepted only three species of Rebutia. A very large number of plants that have been treated in cultivation as species of Rebutia are now generally regarded as varieties, forms or synonyms of a much smaller number of species, or have been transferred to other genera. Plants treated as Rebutia are generally small, colorful cacti, globular in form, which freely produce flowers that are relatively large in relation to the body. They have no distinctive ribs, but do have regularly arranged small tubercles. They are considered fairly easy to grow and they may produce large quantities of seeds that germinate fre…

Min. temperature2 °CJanuary
Don’t water – dry winter rest. Slight shrivelling is normal.
No feeding now.
Cool and bright, 3–10 °C: unheated room, stairwell, cold windowsill or frost-free greenhouse.
February
Don’t water – dry winter rest. Slight shrivelling is normal.
No feeding now.
Cool and bright, 3–10 °C: unheated room, stairwell, cold windowsill or frost-free greenhouse.
March
Gentle start: the first small drink once you see buds or new growth and it warms up.
First weak dose at the end of the month if it is actively growing.
The sunniest window (south or west).
Move it somewhere brighter and warmer and end wintering. Get it used to strong sun gradually.
If roots fill the pot: fresh soil, a pot 1–2 cm larger. Water sparingly for a week afterwards.
It flowers next month – once you see buds, don’t move it any more.
April
Deeply, but only once the soil is completely dry.
Cactus fertiliser once a month at half strength.
The sunniest window (south or west).
If roots fill the pot: fresh soil, a pot 1–2 cm larger. Water sparingly for a week afterwards.
It usually flowers now – don’t turn or move it, and log the bloom in your diary!
May
Deeply, but only once the soil is completely dry.
Cactus fertiliser once a month at half strength.
Best outdoors: sunny balcony, terrace or garden – acclimatise it to full sun gradually.
After mid-May (last frosts) it can go outside – keep it in partial shade for the first 1–2 weeks to avoid sunburn.
It usually flowers now – don’t turn or move it, and log the bloom in your diary!
June
Deeply, but only once the soil is completely dry – more often in heatwaves, preferably in the evening.
Cactus fertiliser once a month at half strength.
Best outdoors: sunny balcony, terrace or garden – acclimatise it to full sun gradually.
It usually flowers now – don’t turn or move it, and log the bloom in your diary!
Above 35 °C, shade it at midday to prevent sunburn.
