Onion seedling medium

Posted by Natures_Nature 5 OH (My Page) on

I planned on sowing onion seeds thickly in a plain ole' six pack seedling flats like the ones you buy most veggie seedlings in, then seperate their tangled roots come spring and plant them out... I seen people do this with a peat based medium, but i understand the consensus here would probably be the 511, or gritty mix. I was just worried about the bark slicing in the fragile tangled onion seedlings while trying to untangle them come transplant time... Should i stick with a peat based for this(i always use at least half perlite), or.. What do you guys start onion seedlings in?

Anyone? You guys use 5-1-1 or gritty mix for onion seedlings? What do you use to start your seeds in? Al, do you start veggie seedlings? If so, what do you use?

I'm not concerned with the plants growing, im concerned about seperating the fine, fragile, tangled onion roots. I know people start onions this way all the time in soft peat mediums, but how would the fragile roots fair with the rough bark comes seperating them?

RE: Onion seedling medium

I just use peat-based commercial potting soil.

To separate the plants, take the whole bundle out of the pot cell, potting soil and all, and gently swirl the roots in a bucket of water, washing out the soil. When they're still wet, gently pull the plants apart. You'll break a few roots, but not very many.

You'd want to plant them out pretty quickly - once the roots dry out, they're toast. I keep the plants wrapped up in damp paper towel as I'm setting them out.
