Giant Barrel Cactus
- Lighting Echinocactus platyacanthus is suitable for part sunny to full sunny places with a minimum of 3 hours direct sunlight per day. If placed outside from spring to fall please acclimate him slowly to the sun which is no longer filtered through a window. Otherwise it could get sunburnt.
- Soil At least 50 % of the soil should consist of mineral components such as pumice gravel, bird sand or perlite. Potting soil can be mixed with pumice and sand or perlite and sand in a ratio of 2:1:1. The Giant Barrel Cactus grows also good in pure pumice.
- Watering Allow the soil to dry between the waterings. Water sparingly if placed cool during winter. The cooler it is placed, the less water it needs.
- Feeding Every 4th to 8th week when in active growth with cacti liquid fertilizer or a standard liquid fertilizer at half strength. New bought or recently repotted cacti don’t need to be fed for the first year.
- Temperature The Giant Barrel Cactus does best with a cool winter rest period at 3 to 10 °C (37 to 50 °F) but also can be placed at 10 to 15 (50 to 59 °F). Minimum temperature is 1 °C (34 °F).
