Garden Tip Tuesday
(come back each Tuesday for more!)
How to divide Irises
- Dig up a bearded iris clumps every three to five years or when the center dies out. They are close to the surface so slip a shovel underneath and pry up. Divide them in the spring after the flowers fade.
- With a knife, separate rhizomes. Check for Iris borers (fat white worms.) Destroy them and discard any soft or rotten rhizomes.
- Each Rhizome division should have one leaf fan (three leaves or so coming from the root. Cut the foliage back to 4 to 6 inches.
- Replant divisions 12 to 18 inches apart with rhizome tops barely showing above the soil surface.
