Tips

• Set transplants with crowns at soil level about 10 inches apart.
• Water deeply when the upper inch of soil dries, keeping crowns and foliage as dry as practical.
• Apply a light balanced fertilizer in spring according to the label and avoid heavy nitrogen feeding.
• Watch for crown rot and remove affected plants while correcting poor drainage.
• Snip faded blooms above a leaf node and lightly shear plants after a major flowering flush.
