I'm starting a few flats of onions indoors right now. I started them in a seed starting mix in six-packs. It's been a few weeks now and the roots are growing out the bottom of the cells. Do I need to repot them into something bigger, or can I just let them do their thing in these small cells? I'm hoping not to have to transplant them because I have a lot.
No announcement yet.
