Starting Celery & Onions

[Sprocket]

Hey all sorry to ask this again but I believe I posted it in the wrong place and inquiring eager spring minds with vision of Robin sightings need to know ;)

I need some advice on starting onion and celery seeds indoors. Last year my onions got really tall and scraggly...probably a light issue but anyway I'd figure all of you'd have a clue what to do. I read somewhere that you could cut back there tops and the bottoms would fatten up a bit.....must be my problem as I am a little on the short side and well...ah hum....the latter in this case seems to be true.

I usually just grow the sets for onions, but when I have planted the onion seeds in the past, I planted them outside after the last frost date. Not that they need that late planting, just happened. Really fertile soil will get you large bulbs in one "trip" if you don't plant them too close. Weeds and grass will be the hard part, onions look like grass seedlings for a while.

So do you plant out your onions from seed early like you would sets or do you have to wait until after your last frost date? I started two different types of onions from seed around the first week in Feb. in peat cells and am itching to plant them soon to make room for other things I want to sow in my windows. Our last frost date here isn't until around the second or third week in May. Anyone know?? :confused:

I've planted them from seeds before but they got real spindly and didn't amount to much so I am hoping to find someone with experience in this area myself.

I start my onion seeds in January or February in flats. They are grown with as much light as I can give them , but mostly on a south facing window sill as my plant table fills up quick. i put little rows of seed every inch going across the flat. I will be planting them out in Aprill when the garden starts.
The onions seed doesn't seem to have much pushing power so i don't cover it, But keep the seed damp with a misting bottle of of room temp water.
i make a few more sowings of onions so i can use up the pk growing green onions, But later sown seeds will never reach the size of the earliest sown ones.
i plant them every 2 inches in the row for green use and thin to 6 inches apart for mature onions. We grow Walla Walla and Yellow Sweet Spanish here.
