Emerogork2, are you talking about Winter Sowing, Indoor growing or Greenhouse growing? If Winter Sowing the only thing I know to prevent leggy seedlings is to plant in the ground before the seedling reach a significant height and the less seeds you use the more room they have to grow. I used seaweed one season and found the root growth was more significant than the containers in which I did not add seaweed. Experimenting is all I know.

Proper wintersown seeds given enough light as they grow, shouldn't get leggy. Or at least it's been my experience that they're more tight and compact than any other method of growing (including greenhouse), I've ever done.

I haven't had leggy wintersown stuff either. But then, all my containers are on the south side of the house and get lots of sun, so maybe that's why.

Personally, I wouldn't try reburying anything other than tomatoes, for fear of rotting the stems out.

Have you tried? I just did and a week later, albeit very soon, they look better now than when they were flopping around.

We shall see...

emorogork2 it looks like you are talking about indoor growing under lights. I did what you are talking about with my indoor growing of nemesia last year. It had very thin stems and very lanky and I thought they were going to die. I replanted them deeper and they completely came around and continued growing and were later able to be transported outdoors. I have done this with other seedlings planted indoors too. this is a ws site and that may be why people were confused. With ws the seedlings shouldn't grow that way.

I have to agree with MaryJo... since this is the wintersowing forum, I thought the OP was about wintersowing, not indoor growing.

So to clarify on my earlier statement, and Emerogorks question of if I have tried it...

Yes, with indoor growing, I have replanted seedlings deeper, with mixed success. Some plants seem ok with it, some of them not so much.
However, with wintersown containers, I have not done so, for fear of rotting out the stems- because of the way wintersowing works, one should not be getting spindly plants, and because of the general dampness and cold/thaw process of wintersowing.

But you might have better luck getting your questions answered over in the indoor gardening forum, particularly the container gardening or growing under lights sections. Or the growing from seed forum might be helpful too. Or depending on what you are growing, one of the more plant specific forums.

Update,,,,

I set up that second tray of seeds and used about less than half of the soil as I usually do. When they grew, just as leggy and weak, I added soil right up to the first set of leaves,

They look great two weeks later, (:
The original tray was placed on a window sill where it dried out and they all died because I neglected to water it,,, ):
