How to Grow Poplar Cottonwood from Seed

How to Grow Poplar Cottonwood from Seed

Populus deltoides seeds are extremely short-lived. Sow immediately upon release from catkins.

Steps

  1. Surface sow or lightly cover.
  2. Keep moist but not soggy.
  3. Germination in a few weeks.
  4. Prick out seedlings when handleable; pot individually.
  5. Grow until sturdy, after last frost.
  6. Harden off in shade 10 days, then full sun.

This replaces a dying tree with its own offspring.
