pick out a site with full sun , providing at least 6–8 hours of unmediated sunshine daily to push unfolding and healthy growth . In hot climates , lite afternoon shade can prevent folio scorch . For indoor or container flora , post near a south - facing windowpane or under grow lights . Ensure the location accommodates its mature size , typically 3–9 foot tall and 3–5 groundwork all-inclusive , or smaller in smoke .

expend Well - Drained , Gritty Soil

Plant in a quick - draining , sandy , or gamy stain mix with a pH of 6.0–7.5 , mime its desiccate native habitat . A cactus or succulent potting mix with added perlite , pumice , or coarse sand ( 50:50 ratio ) is idealistic . quash punishing , clay - rich soil that keep back wet , as Desert Rose is prone to take root rot . For potted plants , insure containers have drain holes to forbid water aggregation .

industrial plant or Repot Carefully

Plant or repot in give , the starting signal of the growing season , to promote ascendant establishment . For priming coat planting , dig a hole twice as wide and as abstruse as the root ball , keep the caudex slimly above dirt horizontal surface to showcase its class . For container , prefer a wide , shallow pot to support the vain stem . Water lightly after plant and invalidate disturbing the radical , as the industrial plant is sensitive to organ transplant shock absorber .

Water Sparingly and Seasonally

Water moderately during the grow time of year ( leaping – summer ) , allowing the top 1–2 inches of filth to dry out out between lachrymation , typically every 7–10 days . In fall and wintertime , reduce lachrymation to once every 2–4 workweek , particularly if the flora is dormant ( leaves drop ) . Overwatering is the primary cause of root putrefaction , so err on the side of underwatering , peculiarly in humid climates or indoors .

Mulch Lightly for container

For terra firma - plant Desert Rose , apply a tenuous ( 1 - inch ) level of gravel or rough-cut sand around the base to mime desert conditions , improve drain , and deter weeds , keeping it away from the stock .

Fertilize During alive Growth

Feed monthly during spring and summer with a balanced , water - soluble fertiliser ( for example , 20 - 20 - 20 ) adulterate to half strength , or apply a cactus - specific formula high-pitched in daystar to boost florescence . practice to moist dirt to forestall root sunburn . Suspend fertilisation in declension and wintertime when development slow up or the plant enters quiescence , as excess nutrients can harm the plant .

Prune for Shape and Health

Prune in early spring to shape the flora , encourage branching , or enhance its bonsai - like form . move out utter , long-legged , or overcrowded stems using clean , incisive tools , and cut above leafage nodes to promote fresh growth . Pinch back tips for bushiness or vacate the caudex over time for a striking effect . break baseball mitt , as the sap is toxic and can irritate skin or eye .
