Light Thrives best in bright light; will love your brightest windowsill (try South-facing if in doubt!).

Water Allow all the soil to dry out between watering; if the leaves curl it may have too much sun and too little water; if it starts to grow mushy or rot at the roots, likely too much water and too little sun.

Humidity Low humidity is perfect for cacti; a hose down to clean now and again is fine as long as the plant dries and doesn't sit damp.

Soil Needs a well-draining pot and potting mix; look for specific 'cacti and succulent' soils with plenty of sand and other well-draining materials. Only repot if absolutely necessary: use the next size pot up, repot in the spring, and no more frequently than every three years.

Food Feed every two months in the growing season, and every three in autumn and winter. Use 'cactus' labelled feed.

Temperature Likes temperatures of 20-32°C; don't let it drop below 10°C in winter.

Pet-safe No, this plant is toxic to pets and small humans.

Sprouts Top Tips This is a flowering variety; to make it more likely you'll see the blooms, let it have a proper dormancy in autumn/winter with lower temperatures and less frequent watering and fertilising, and then increase these as the weather warms. The warmer the cactus is in summer, the more likely you'll see flowers!
