Best Time to Divide Perennials in Zone 7 (Jersey Shore)

Fall Division for Stronger Spring Growth

Hostas, black-eyed Susans, astilbe, salvia, coreopsis, and hydrangeas all divide best in fall as they enter dormancy.

Why Fall?

• Winter rest heals transplant shock.
• Roots grow in cool soil.
• Spring energy goes to shoots, not recovery.

Bonus

Division multiplies plants, invigorates parents, improves blooms and disease resistance. Do it every 3–4 years.
