Depends on variety....do you know what kind it is? On average about 75 days after the seed is planted...

You'll know it's ready if the spot on the belly is yellow

Just saw this
Sorry

planted 230 TX Legends today...5 bunches...count was really short this year, but the quality of the slips was excellent...i'll have to hand water from the lake until next spring...TLC

b4 u ask, the mail box is to store tools / ant killer / Sevin Dust

Nice! I got mine planted Sunday. And they were probably the best looking bunches I have ever received.

Im late sigh

When you plant this early, do you have to cover your onions during cold weather, or just let them fend for themselves? Is there anything else, besides planting early, you do to get the largest onions?

I covered mine in 2021 and my mom didn’t. Mine looked a lot worse than hers when I uncovered them a few days later. The snow insulated hers. Mine recovered fine but I won’t cover them again. Per dixondale fertilize them every 3 weeks or so with Ammonium Sulfate. 21-0-0. I mix in 13-13-13 when I rake/till the bed then just 21-0-0 after that.

i agree, i've had my onions freeze to the ground and they came back...watering is the key...Dixondale has some special onion fertilizer that i put down when i plant, but only then...as Derek said 21-0-0 every 3 weeks until they start bulbing...i have FULL sunlight at my lake house so i'm thinking i'm gonna have sum good'uns next May...i'll be watering with lake water, so the fish poo will add a little zing...we'll see...ur lernin' Derek

Thanks. I'm an expert at growing onions the size of golf balls. Ordered some sets from Dixondales, which should be in next week.

3 weeks, first 21-0-0 fertilizing

we will be putting in an order at dixondales,good looking onions

not so good after that 3 day hard-freeze, but i think they'll survive

Dixondale Farms regarding FREEZE

After any hard freeze, the plants will need watering, since the ground usually dries out significantly during a freeze. Give your plants a couple of weeks to bounce back. They need time to generate more carbohydrates, which is their life source (not to mention their flavor source). If you see new leaves emerging, your plant’s on its way to recovery! Check on your onion plants more often than usual for a few weeks, for signs of new growth.

onions usually come back alright,been my experience. good luck

Hope yours do come back and produce for you. I put mine out early the year we had the deep freeze and it really stunted them badly. That said it got down to -12°, they were covered with a tarp and over a foot of snow. Per the Dixon Dale site, they need to be watered after the freeze as it dries out the ground. I didn't do that and it could have been the problem.
Good luck.
