When is the best time to plant onions?
Belen E on Dec 16, 2018
BEST ANSWER: Early spring is best in most growing zones, but if it's more temperate where you live, you may be able to plant now or in the fall to harvest onions all winter long.
How far apart to plant?
Darrell J on Mar 14, 2020
BEST ANSWER: I plant mine in one row with the plants staggered about 4 inches apart. As in a widened V with one plant at each point down the whole row. Saves space and makes weeding less tedious and makes the breaking down of the tops at end of season easier as well. I got very large bulbs even planted in this manner
Are these plants or bulbs?
Kathy S on May 25, 2020
BEST ANSWER: We appreciate you reaching out to us. These are bulbs for planting.

If you have any further questions please don't hesitate to reach back out to us. Have a great day!
Are these onion sets? The bulb?
Jeanie H on May 18, 2020
BEST ANSWER: We appreciate you reaching out to us. Our onions are in bulb form.

Very disappointed
We have always purchased all of our onions through Starks and this year none of our onions made it. They were planted and have all died. So disappointed in the product that were shipped to us.

Sweet & Delicious
These onions grew beautifully; productive, sweet and delish! They didn't store very well though, sprouting within a few weeks even in the root cellar with great conditions for storage. The Candy onions, also productive and excellent eating, have store very well, much better than the Walla Walla; in fact, we are still enjoying them!

First place at the fair!
These won first place in th local fair for size and just looking some something you'd want to eat! They are sweet and juicy. They are super easy grow, we didn't do much besides plant in dirt. They are not the best for long term storage but still a summertime favorite here! We live in SE Michigan zone 5 and just pulled up a few perfect looking softball sizes this week ( July 12)

My favorite onion
Last year we had 2-50 foot rows of Walla Walla onions in S. Colorado. They were wonderful! We are from the Pacific Northwest have have always loved these onions and found they even grew great in Colorado!
This year we planted 1-50 foot row and so far 95% of them are growing beautifully! We plan to grow more from Stark Bros. again next year too!

So far so good
I ordered an onion package, walla walla and redwing, along with some garlic for early spring planting. They arrived while the snow was a foot deep and the ground still frozen solid. I was super excited, they were wonderfully fragrant, plump and green! I stored them in a cool place and then suddenly became very ill for almost a month. When I was finally recovered enough to begin planting, I discovered that both sets of onions were all dried up. I wanted to cry! I planted them anyway, in rows in a big raised bed amended with compost, and I am happy to say that two weeks later it looks like all but a few are sending up green shoots! I will update this review at harvest, but I have high hopes. Everything I’ve purchased from Stark has been exceptional, and your customer service sets the bar very high. I will always do business here.

Awesome walla walla onions
They were great and I'm ordering more this year. After ordering they came in a sufficient amount of time like I was told.

Poor results from the Walla Walla Sweet Onion
We have been gardeners for over 40 years. Trying the Walla Walls onions for the first time last year I was anxiously awaiting the results. Unfortunately, all but a few of the onions survived. The tops dried out in September but before we could pick them they started to regrow and by doing so they became all mushy and not suitable for storage.
