FAQs
Osteospermum sometimes stops bloom during very hot dry weather condition . Do n’t occupy , once the heatwave is over they will set off to blossom again . In the interim , ensure that you irrigate them on a regular basis . If the plants dry out they can sometimes strike down bud . Container grown plants may call for watering daily in very hot weather condition . Once every few days may be require in plant life in the earth while the dry while live .
It ’s difficult to be sure what the problem is without knowing the form , but here are a few possibilities .
Firstly , make certain they are in a warm sunny post as they do not unremarkably like cold weather . Secondly , water them as they begin to dry out , but not too often , as sitting in wet soil can cause the theme to waste . You should also feed them every two to three week in the grow time of year .
It may just be that the weather has been a little too blistering for them and they will perk up of their own conformity when it cools down .
This rather depend on the variety of osteospermum you have . Many varieties will last over wintertime , but some tender varieties that are sold as bedding or houseplants , will not . If yours is a hardier variety , you should be okay if it is in a fairly sheltered spot . I would urge take some cuttings in late summertime or early autumn just in case it does n’t make it through . If you are concerned though , you could savvy it up and put it in a pot in the household or greenhouse over winter .
