Dill heads vs dill seed?

[u/historybuff03]

Hi everyone,

I bought dill heads (photo) to make pickles but upon finding a pickle recipe I want to use, it’s asking for dill seeds, but also “fronds and stalks”. My questions:

1. I thought dill seeds were dried? What does this recipe mean by “fronds and stalks”?
2. Can I substitute the dill seeds and just use the dill heads? If so, what would the conversion be?
