Seasonal Houseplant Maintenance: When to Prune and Repot in the Northeast

Timing

• Pruning: Can start February 1 (days lengthening, growth resuming).
• Repotting: Wait until after March 1.

Repotting Rules

• New pot max 2 inches wider in diameter.
• Or root-prune: remove plant, shave 1 inch off root ball all around, repot in same-size pot with fresh mix.
• Pots must have large drainage holes and saucers.
• Empty saucer 1 hour after watering—never let plants sit in water.

Why Wait?

Repotting during winter dormancy leads to root rot. Spring's increasing light supports quick root recovery.
