But they ca n’t deal cold weather – growth stops when temperatures put down to 50 ° atomic number 9 as plant go hibernating .

alfresco of their hardiness range , they demand to be lifted , pot , then brought into a Robert Frost - free environment . But first , it ’s helpful to prep them for dormancy .

Use clean , sharp garden snippet and shear the leafage back to one or two inches above the soil air .
At the same time , withhold water and finish feeding if you have n’t done so already .

While dormant , allow the soil to dry out between water app , give the plants only a small sip to barely moisten the roots . In insensate weather , these pinnace plants are prone to root buncombe and sloshed grease must be avoided for level-headed storage .
When new growth appears as spring approaches and the days start to lengthen , bit by bit increase lachrymation .
Once maturation is about four inches improbable , maintain slightly moist soil and feed with an all - purpose fertiliser with a balanced expression .
