All types of flowers in my garden are having this same problem. Their flower stems bend down. It looks like they are wilting but the leaves are healthy and the flowers are large. And the plants get plenty of water. Could anybody tell me if it is a soil problem and how I can fix it? Thank you!!
Your plants may be suffering from cold, wet and lack of sunshine! Many cultivars are bred for large blooms. Stems have grown too long with rich soil and plenty of moisture. A bit of warmth will fix a lot of problems.
