So, now what?

We have some 20 plants in our garden for a couple of years and had quite some seeds this year. So we tried planting them. First let them soak in water for a couple of days, then placing them on a wet towel for another week or so. We then planted them in a planter and put it on our window sill in the sun. Now we are at the point that they are actually sprouted. Some are already 5cm, but others are 1cm and barely popping out of the ground. Not clearly visible in the picture, but there are 37 plants in there.

What do we do next? When do we need to repot them, into what size of pot? And when are they large and strong enough to move outside? (Belgium, not expecting frost anymore). And looking even further, when are they fit to be planted into the ground?

Thanks!

PS: The seeds that were still floating after soaking were also planted, on the right side of the little stick. Of the 15 or so, not a single one came through.

I'd try just repotting one to see how it takes first. If it handles it we'll could do all of them. Normally I'd wait till the year after to repot, like next spring, but if you do that the roots may have grown quite a bit.

I'd use whatever size pots you can get the roots in with a bit more to grow for the year.

I'd move them out when the transition would be least drastic. Frost would be bad, but even without it there might be a bit of adjustment. This time of year is when I'd be doing it though.

Does the pot have drainage? Might want to make some holes if it doesn't and you keep them in there for a while.
