: I recently dug up some lavendar irises and planted them in my yard. A few have bloomed but most of the leaves have fallen over. How can I assure that they will keep growing? And do irises spread at all?
Irises need good drainage and full sun. Do not overwater. The rhizomes should be planted just below surface or they wouldn't bloom. After about 4 years you have to divide and replant the clumps because they will be overcrowded. Fertilize in early spring and after bloom.
