17 Questions
Why did you choose this?

I love Walla Walla Sweet. My mother grew these all the time I was growing up. Our soil produced large sweet onions.

I like to eat them and I've grown them before.

Good for growing in our zone

short time to maturity and that they have lower sulfur.

60 pack ?

Yes it is a package of 60 bare root bunches.

Do the walla walla onions come in sets or starter plants?

Hi Brian, these are sold as onion sets.

When is the best time to plant onions?

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.

Are walla walla short day?

No, Walla Walla onions are long-day onions.

Can the sets be "stored" for a couple of weeks before planting if the weather is too cold?

Absolutely! Keep cool,dry and dark.

Do walla walla onions keep well in a root cellar?

Yes! Great place to store them. I live in Colorado and typically harvest in the September/early October time frame. I top trim the onions long (leaving about 2-3" of stalk) and trim the roots. Then I give them a gentle wash with water. After thorougly drying them outdoors in the air, I like to lay the Walla Walla's out on newspaper and put them in the basement where it is cool, dry, and dark. Light will stimulate the onions to sprout so dark is best. In my cool, dark, dry basement (or your cellar) my Walla Wallas last typically until December or January and by then they have mostly been used. I always grow Walla Wallas and I cannot say how their shelf life compares to other types of onions, but I have been very pleased with their durability.

How far apart to plant?

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

Shipping cost?

Shipping cost is determined by dollar amount spent and this will be indicated on your order prior to check out.

Do you sell chocolate mint bedding plants?

No I am sorry we do not sell that variety.

How much water needs?

Water thoroughly after planting, and regularly thereafter, about once a week if there is no rain. Onions have shallow roots, so don’t let the soil at the base of the plants dry out and crack.

Wonderful huge onions
These are the most Wonderful huge onions. Even though they are a little pricey, they are sweet and not hot, they are great flavored onions. They have been easy to grow and are amazing. these don't store well for long periods like in a cellar, but I chop them and put in freezer baggies. I would highly recommend buying and growing these.

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.

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!

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)
