Perennials Gardening

Perennials can be transplanted all month, keep on top of deadheading duties.
In mild climates, fertilize roses once a month throughout the summer.
Bearded irises should be separated and given a bit more space between now and August, especially if it hasn't been done in the past three to five years. After the last iris blooms fade, stop giving them water. When leaves start turning brown, trim them down to green areas in a two-snip pyramid shape. Dig them up and cut apart their knobby rhizomes. Set them in the shade for a few days to harden off. Replant at the same depth (rhizomes should be approximately level with the ground) in soil that's been amended with processed manure and compost.
