By now your bearded iris should have given you a truly delightful display, and have started to enter their period of dormancy. If your iris have not flowered well, there could be a number of reasons for this.

Iris need at least half a day of full sun, and will even do well in full sun all day.

Some of the darker flowering varieties may flower better if they are in the shade in the afternoon, but generally they are true Aussie sunbakers and love to languish in the open.
