When to plant dill in zone 6b
Zones 6a and 6b share the same average frost dates in our data, so this page covers both.
Method: Direct sow: Direct-sow outside. Dill doesn't transplant well, or doesn't need the extra time indoors.

Spacing: 4 per square foot (square-foot-gardening spacing). Mature height: 2-3 ft.
Dill is an easy, low-maintenance herb that mostly takes care of itself once it's in the ground, the main thing to get right is where you plant it, since mature dill doesn't get along with one of the garden's most common root crops.

Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Dill needs about 55 days from sowing to first harvest.
