Gasteria rawlinsonii thrives in bright light with some direct sunlight, average warmth and moderately moist, fertile, well-drained soil coupled with monthly feeding during the growing season.
Gasteria rawlinsonii has no need for extra humidity. It requires pruning to keep it neat and reduce pests and diseases. Repotting is only needed when it becomes pot-bound. Keep reading for more on these growing conditions and how to provide them.
Gasteria rawlinsonii grows best under bright light with some direct sunshine.
Avoid exposing the Gasteria rawlinsonii to too hot sunlight before acclimatizing it, as it can get sun burned.
Ensure to rotate the pot regularly so that the plant can receive light on all sides for even growth.
It can also grow under a grow light if the natural light is not sufficient.
Water Gasteria rawlinsonii thoroughly during the growing season while allowing the top 2-3 in. of soil to dry out between waterings to maintain the soil moderately moist.
Significantly reduce watering during the cold season as growth is minimal at this time to keep the soil slightly moist but do not allow the soil to dry out completely.
Make sure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot disease.
Avoiding wetting the center of the rosette as it can lead to rotting. Watering from the bottom is a better option.
Use water that is at room temperature water to avoid shocking this tropical plant.
Average warmth temperatures from 18-290C) are ideal for Gasteria rawlinsonii. The sudden change in temperature between day and night is perfect for the growth of this succulent.
Gasteria rawlinsonii has no need for high humidity. Average room humidity is ideal for this plant.
Feed Gasteria rawlinsonii with a succulents fertilizer monthly during the growing period as they are slow growing and therefore do not need frequent feeding. Do not feed during the cold season as growth is minimal at this time.
Repot Gasteria rawlinsonii at the beginning of the growing season only when the plant becomes pot-bound. Use a shallow rather than a deep pot as they have shallow roots.
The pot should be only 1 size larger than the current one. Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot disease.
The best soil for Gasteria rawlinsonii should be rich in organic matter, loose and free-draining to avoid getting soggy soil. The soil should be loose enough to allow water to drain out fast enough like these Cactus and Succulents Soil available at Etsy.
Pruning Gasteria rawlinsonii involves removal of dead or diseased leaves to maintain the plant neat and discourage pests and diseases.
Cut the leaf at the base with a sharp knife or a pair of scissors to detach it from the stem. Avoid excessive injury to minimise fungal and bacterial infections.
Gasteria rawlinsonii can be propagated from offsets (pups) which form at the base of the plant.
Select an offset which has several leaves and carefully seperate the offset from the mother Gasteria rawlinsonii by cutting with a sharp knife or a pair of scissors.
Allow the offsets to dry (callus) for 1-3 days before potting to prevent rotting.
Plant the offset in free-draining soil and ensure the pot has a drainage hole to prevent the soil from getting soggy.
Water sparingly, only when the soil is dry to avoid getting soggy soil as it can lead to root-rot.
Allow the new Gasteria rawlinsonii to be well established after which you can begin routine care.

Rot at the base followed by yellowing and shriveled leaves in Gasteria rawlinsonii is an indication of basal stem rot disease due to overwet conditions.
Remove and discard the infected parts to prevent spread to the rest of the plant.
Do not overwater in the cold season and reduce watering significantly to maintain the soil slightly moist.
Ocassionally use a fungicidal solution to water the Gasteria rawlinsonii to prevent the disease infestation.

Do not allow the soil to dry our completely, maintain it moderately moist during the growing season and slightly moist in the cold season.
Brown soft spots in your Gasteria rawlinsonii are an indication of leaf spot disease which is promoted by poor air circulation. Ascertain that there is proper air circulation for the plant.
Wilted and discolored leaves in Gasteria rawlinsonii are caused by overwatering during the cold season. Water the plant sparingly during the cold season and always allow the soil to almost dry out between waterings.
