Planting & stewardship
How to help Dill thrive
- 1
Prepare a fertile, well-drained bed and keep seed or transplants evenly moist through establishment.
- 2
Thin to the final spacing; crowding reduces harvest quality.
- 3
Watch for aphids and caterpillars and protect sensitive growth from a hard freeze.
- 4
Harvest before sustained spring heat causes bolting or poor quality.
