Gardening question.

So I've planted 4 krakka root seeds and 4 dzemael tomato seeds because I've heard that was one of the ways to get silkis seeds, but now I find that kraka are ready to be harvested but the dzemael are only halfway through.
If I harvest kraka now before dezmael seeds are ready to be harvested, will I get a chance at silkis or do I have to wait until dzemael are ready?

The seeds you'll get are already decided the moment you planted them. No need to wait for others to finish. The tomatos will also give sylkis or some other seed that'll come up from the same combo even if you plant new seeds next to them.

Ah thank you, much appreciated.
