Q.lavender calla lilies
I have moved gift houseplant calla lily to larger plastic outdoor pot from small gift pot. The calla has developed about 6 or 7 new blooms still in budding stage that appear heavy and severely droop. Leaves are not as droopy and all look healthy. I have not fertilized it. Suggestions? Would more sun exposure help? It is on front porch with morning sun and afternoon shade.
