calla lilies / coloured arum lilies
i have the above flowers in containers as well as in the garden. This year they had 50% flowers than normal and a few days after the flowers have opened, the beautiful bright colours changes to a terrable darky mixture of coloures.They also die down very quickly thereafter. COULD IT BE THAT I HAVE TOO MANY BULBS IN A CONTAINER OR COUD IT HAVE SOMETHINH TO DO WITH THE PH OF THE SOIL. i MOSTLY UDD\\SE RAINWATER SO I DOUBT THAT WATER COULD BE THE PROBLEM. I FEED THEM ONVE A MONTH WITH PLANTFOOD FROM OUR LOCAL NURSERY. please help !! KIND REGARDS DEON ERASMUS PORT ELIZABETH SOUTH AFRICA.
