late spring after danger of frost past

Herb garden (inside bottom of U) & with long growing potatoes?

Successive sowings can be done every three weeks to harvest fresh greens continuously.
Direct seed (recommended): Sow in spring as soon as the soil can be worked. Plant seeds 1/8- 1/4" deep, 2 seeds per inch. Thinning is not necessary, but a 4" final spacing produces healthy, full plants.
Transplant: Dill can be started inside in individual pots or cells. Sow 3-5 seeds per cell and thin to 1-2 plants each. Transplant to garden using 4" spacing in rows at least 12" apart.
