The dill plants are producing seeds. This is one of many seed producers in the garden. The first attempt at storing seeds became a moldy mess and I had to throw them out. The next batch was left to dry out on paper towels for a couple days before storage. Another batch was just thrown into the summer garden (an update on a later date about that). The only say I can say is that I did a terrible job at spreading the seeds. It is one big clump of dill. There are still more to collect and I will be doing that the next couple of weeks.
