Crassula ovata
EasyOpen jar only
Thick glossy leaves on a little trunk. Bright light and dry soil.
What the simulation uses
- Light
- 8,000 to 40,000 lux
- The brightness it grows well in.
- Humidity
- 20 to 55 % RH
- Air moisture it is happy in; below the lower end it dries out.
- Temperature
- 13 to 29 °C
- Comfortable range; outside it growth slows.
- Dies at
- below 2 or above 35 °C
- Days beyond these temperatures kill it.
- Soil pH
- 6 to 7 pH
- Soil acidity it prefers.
- Grows up
- 0.5 cm/month
- How fast it gains height in good conditions.
- Spreads
- 0.4 cm/month
- How fast its edge creeps outwards.
- Copes with wet
- poor
- How well it stands soggy soil; poor means rot comes quickly.
- Copes with still air
- poor
- Sealed jars have still air; poor means grey mould finds it.
- Copes with shade
- poor
- How well it holds on in dim light.
- Copes with drying
- excellent
- How well it survives the jar drying out.
- Water use
- 0.02 ml/cm²/day
- Water drawn up from its roots per cm² of leaves in room air; a sealed jar cuts this to a fraction and returns it down the glass.
- Leaf drop
- 1 %/month
- Share of its leaves it sheds each month as litter for the cleanup crew.
- Soft leaves
- no
- Soft new growth that hungry isopods will nibble.
- Full size
- 20 cm tall, 17.5 cm wide
- Its size when grown, before the lid stops it.
Care
- Day length
- 6 to 12 h
- Substrate
- Dry
What kills it
- overwatering / root rot
- humid still air
- low light stretching and collapse
Description
Its thick leaves store water, so it needs strong light and soil that dries out fully between waterings. The still, humid air of a closed jar rots it fast. Use an open, sunny dish instead.
Also called money plant, friendship tree.
