Can you bury broccoli seedling stems?
Generally, yes, you can plant leggy seedlings deeper in the soil to help compensate for the extra-long stems! However, avoid the temptation to plant them deeper right away, when they’re still very young and tender. Weak, thin, small stems may rot once they’re buried in damp soil.

Do broccoli seedlings need support?
Broccoli seedlings that are spindly and falling over by the time they’re ready to transplant do need a little support, but they don’t need to be staked. Instead, dig a deeper hole than usual and bury the stem up to the first true leaves.
Why are my broccoli seedlings falling over?
They fall over because the transplanted roots can’t find enough water to keep the plant stem rigid. Watering the plants doesn’t completely solve this, because the root hairs need time to grow into close contact with the soil particles.
Can you plant broccoli stems deeper?
Cabbage, broccoli, cauliflower, brussels sprouts and plants in the cabbage family will be helped by planting them a couple inches deeper than they were originally growing. Deeper planting places part of the long stem underground giving the plant a more secure anchor.

- Take care in extreme temperatures.
- Go next-level with nitrogen.
Can I bury Brassica stems?
When I pot on (transfer to a larger pot) brassica seedlings, I always bury part of the stem, so that their lowest leaves are just above the surface of the soil. This encourages more root formation and gives them greater stability, particularly if they are leggy.
Do leggy seedlings recover?
The good news is, leggy seedlings can usually be fixed before it’s too late. I’ve transplanted hundreds of tall, floppy seedlings with success, most of which went on to recover and have normal, productive yields.
