Yes, Dill seeds can be eaten fresh.
Dill seeds are great whole or crushed. They add a pungent and sour flavor to the dishes they are used in. These seeds can be fried, toasted, or used in breads and broths. Dill seeds are often said to taste similar to caraway seeds with a lighter flavor.

While the dill plant itself will die off each year, its seeds will survive over winter and sprout new plants the following spring. However, your dill can grow year round by growing the plant in a container and bringing it indoors during the cold season.

Dill is a very quick re-seeder, and in some areas can be considered invasive.
When dill flowers go to seed, the wind will blow the dill seed all over, causing potentially unwanted dill to sprout. Some ways to help minimize unwanted spread of dill are deadheading the seed heads and heavily mulching the surrounding area.

Allow seed to ripen on the plant and turn to a brown color. Clip the seed heads into a paper bag to dry for about a week. Separate the seeds from the chaff. If the seeds are fully dry, store them in a cool, dry place to be planted during another season.
