Why didn't my agapanthus flower this year
I grow two types of agapanthus. The big ones with the great big white and blue flowers had a wonderful summer and flowered prolifically but the smaller variety with the deep blue smaller flowers produced 2 flowers on one bed and none on the other. In past years I have had 20 on each clump. They are grown in raised beds and have been allowed to spread over about 10 years. They have not quite filled the beds so they are not yet too crowded. I watered and fed them and they enjoyed full sun all summer. Do they have a finite life span for flowering or should I just keep my fingers crossed and hope for flowers next year? The leaves were fine and glossy so they were not diseased.
Also do other growers cut their plants to the ground in spring?
