This may sound odd, but cosmos like very tough, poor conditions. Low soil fertility. Very little water. If you overcare for them (too much water, too much fertility and too much shade), cosmos becomes tall and spindly and blooms sparsely. They like it hot and dry. Think Texas. When not exposed to 鈥渢ough-love鈥 growing conditions, this otherwise beautiful flowering plant becomes tall, spindly and sparsely floriferious.
