Dill is frost sensitive. It is easily started outside directly into garden soil. Sow the seeds around May 20th, 3” apart. For a constant supply of leaves, sow seeds again one month later. Days to germination: 7-20.
Harvest leaves anytime or cut entire plants. For seeds, wait until the seeds are ripe.
Dill is an easy seed saving crop. It is insect pollinated and cross-pollinated but will only cross with other dill. Remove early bolting plants. Let the rest of the plants flower and collect the mature seeds.
