I'm a bit confused about the instructions for planting Rudbeckia (Black Eyed Susan) from seed. The guidance says to sprinkle the seeds on seed starting mix about six weeks before the last frost date, but it also mentions that seedlings should be planted outdoors after any danger of frost has passed. Does this mean I can directly sow the seeds 6 weeks before the last frost date, and then just transplant the seedlings after the frost? How does it all work?

You're on the right track! Starting seeds indoors gives them a better shot at blooming this season, while seeds sown directly outdoors may have to wait longer depending on the conditions. Just be patient with them!
Exactly! Directly sow seeds outdoors six weeks before the last frost, or if you’re starting indoors, wait until the frost has passed to plant those seedlings. Mother Nature has her way of ensuring seeds germinate at the right time!
Yes, you're correct! If you decide to start them indoors, wait until after the last frost date to transplant. For outdoor direct sowing, just plant the seeds straight into the garden about six weeks before the last frost. However, do keep in mind that outdoor-sown seeds might lose some to weather or pests, but they'll likely be fine too.
It sounds like the instructions are saying to start your seeds indoors about six weeks prior to the last frost date. Then, you should transplant those seedlings outside once all frost danger has passed. It's pretty common practice, and starting seeds indoors tends to yield better results!
Thanks for clarifying! So I'll start them indoors and wait until it’s safe to move them outside.
Yep, you've got it! If germinating indoors, hold off on moving seedlings out until all danger of frost is gone. Direct sowing is fine if you want to go that route as well. Just be ready for some seeds to be lost to nature if you're sowing outside!

Got it, thanks! I’ll just have to keep an eye on them!
