Like other succulents , Calandiva need well - draining soil with a slightly acidulous or neutral pH. Add gumption or perlite to yourpotting soil , or buy a portmanteau made for succulents and cacti . Plant Calandivaoutdoors , about 8 to 12 inches ( 20 to 30 centimetre ) apart . Give the plant full sunshine outdoors and as much sunshine as possibleindoors , either with direct or bright , indirect sunlight . A spindly - looking plant may lead from too fiddling lighter .
Because Calandiva is a drought - tolerant plant , it is skillful to err on the side of too little water rather than too much . Water the plantthoroughly every calendar week or less , but hold back until the soil is ironic before rewatering . Apply a balanced fertiliser once a month during the growing time of year to encourage blossoming , using a smooth fertilizer for an indoor plant and either a fluid or granular type for outdoor plants .
modest pruning andpinchingare all Calandiva ask to advance flowering and create a more bushy full embodiment . Cut back the tallish stem that come up above the leaves after the flowers finish blooming .
Calandiva necessitate long night , from 14 to 16 hours of darkness , and shortsighted day to grow flower bud , which form during the recent crepuscule and winter months . If possible , keep indoor plants out of artificial light during the winter by placing them in a moody room or closet from the recent good afternoon until morning . Once the bud form , let the flora persist anywhere , and look for the first blossoms on your plant in January .

If your plant has discolored leave or you see furry web - similar heart and soul , the problem could bepowdery mildew . If the leaves are just wilted , the industrial plant may haveroot moulder . In either character , consider whether the soil is too lactating and curve back on watering or apply a commercial-grade product as directed on the packet for powdery mildew . If you see tiny bugs on the flora , such as aphids , brown plate , ormealybugs , wipe them off softly by handwriting .
