What is the one gallon start for 1799 what does it include?
Stormvet1st on May 19, 2016
BEST ANSWER: I am super pleased with both the goji berries. One small plant but it grew very fast! They produced lots of berries in August.the berries are very tiny. We ate a hand full every day for a couple of weeks. I kept them watered all summer . They
are easy to grow. I mulched them and i don't even have to weed.
with the asparagus, whats the difference between 1 gal. small stark container and the bare root?
John on Feb 2, 2017
BEST ANSWER: Bare-root means the plant ships without soil or a pot; the small-gallon container is a pot that contains the crown, rooted in soil.

Brian S on Apr 3, 2016

Are these plants both male and female or just male? What is predicted life of bed once producing( after three years )?
Farmer on Jun 18, 2017
BEST ANSWER: jersey knight plants will last over 25 years if you take good care of them. Keep weed free and use good compose or manure in early spring and compose in mid summer. Plants are mostly male but I always get a few females with a order.
How deep should a raised bed be that would support asparagus?
Willie S on Apr 7, 2016
BEST ANSWER: A raised bed that is at least 12 inches deep would accommodate the crown and root system of the asparagus.
After about the second year I couldn't keep the grass out of the asparagus How How do I keep the grass out from the plants ?
Jeff W on Mar 14, 2017
I have been growing Jersey Knights for about 20 years. I have been using straw as a mulch (my straw comes from my goat barn, but have used fresh as well), the asparagus pushes through it no problem, the grass does not, with first and second year plants i put a small stake where the plant is, as these sometimes need help to break through, so i need to know where they are. After they are up i pull the straw away from the shoots a fraction. I know there are some who don't like this method, but it has worked for me in CT. - you may need to do some weeding first time around, it all depends how established the grass is - The asparagus can get dug up and re planted, never seems to suffer when i have moved them (early in the year before they sprout)
Will Asparagus prouduse the first year?
Richard N on Feb 27, 2016
BEST ANSWER: Yes it will spout but since it is the first season the asparagus is very thin, like linguini.
It is not worth eating and you shouldn't. Be patient a wait at least 3 years. Sorry.
What do you mean by pk10?
Chill on Mar 15, 2020
BEST ANSWER: They arrive as bare roots, 10. Mine looked like a bundle of ramen noodles! They were also dusted with a powder to keep mold off. I called Customer service who reassured me this was normal packaging. Just 1 year later I had a beautiful huge bed of plants. High quality!
How long to produce?
Shawn S on Jun 14, 2018
BEST ANSWER: Three years, sometimes two.
To your refs will they produce the next year after planting?
Shawn S on Jun 14, 2018
BEST ANSWER: no, they take 3 years to produce. This was my third year and we have 6 plants. We got about
10 spears. So worth waiting for, too!
The asparagus is plants not just roots right?
Judy H on May 21, 2020
BEST ANSWER: They are root crowns that you plant and they come up the following year. I
think I planted in the fall and they came up healthy the next year and after a year
we were able to harvest some. They are growing really well and delicious now.

Is after April 4th too late to plant this year?
Stacy T on Apr 1, 2020
BEST ANSWER: Stacy T - I just planted my Jersey Giants in Denver where my garlic is just coming sip through the mulch and the rhubarb is just starting to break ground. Tulips are not yet in bloom but crocuses are done. Earlier plantings of asparagus are just beginning to erupt. I'd encourage you to plant by the end of April. It will be too years before you can really get a harvest, so don't worry about rushing it!!
Can I plant the green asparagus varieties with the purple asparagus?
Paulina S on Apr 9, 2019
BEST ANSWER: with correct spacing, sure. I have 3 varieties in the same garden
Can these be planted in the same raised bed as I plant my tomato plants ?
Mary G on May 16, 2020
BEST ANSWER: Yes you can but remember not to disturb the asparagus next year when you plant your tomatoes or other plants.
I saw that each crown will produce about a pound of asparagus. How many spears does this translate to, and do the number of spears increase with age? Do asparagus require or benefit from division after so many years?
Barbara S on Apr 23, 2020
BEST ANSWER: I am into my second year growing asparagus in SW AZ, started my plants in an 8' stock tank, end of year one the crowns outgrew the tanks so in the Fall I replanted them in three 15' rows, plus added some new Jersey Knight crowns, all are doing well, should have a good crop next year, don't expect much this year. The poundage and numbers would, think vary, by the quality of soil, irrigation and climate, hard to predict in the AZ desert.
can they be planted in September in mi.?
Tom A on Sep 17, 2019
BEST ANSWER: Thank you for your question. Because weather and soil conditions vary so much from year to year and even within your zone, it's best to think of your planting time as a range of favorable conditions instead of an exact time.

You can plant new plants and trees: 1) when the ground is not frozen, 2) when daytime temperatures are above freezing (32??F) and below 90??F, and 3) when extreme weather (blizzard, hail, torrential rain, etc.) is not in the forecast. Be sure to keep plants watered if you're transplanting in warm and/or dry weather.
Can I plant these in containers if I don't have a bed ready?
Kathy L on Jun 22, 2019
BEST ANSWER: You probably want to do this because it hasn't' stopped raining long enough to get a bed ready? It's been a great growing season *sarcasm*. If the crowns and root are still dry and packaged in what they arrived in I would try to keep them in this condition, cool and dry. But, if you are seeing sprouting or shriveling, use at least a 2 gallon nursery pot so you don't have to coil or cut or scrunch the roots and pot them up with the crown just below the surface. I wouldn't use straight garden soil or straight potting mix, but mix the 2, half and half, so it drains well in the pot, but roots out into the garden when finally set out. You will set them out much deeper according to the directions Starks includes with the starts, but I wouldn't break up or disturb any rooting that takes place in the container unless it's gotten root bound by the time you plant out.
Asparagus is NOT a container garden candidate. You are just healing them into a pot until the weather cooperates. Keep watered and only lightly fertilize once you see any green growth. Here's hoping the Midwest dries up enough soon...and then moderates to get us thru the rest of the growing season. Happy gardening! Later, Beth
Are these all male plants?
Faye A on Feb 23, 2018
BEST ANSWER: Stark Bro's asparagus plants/roots are available as primarily-male selections. A female may appear from time to time, but they can be removed if they do (you'll notice they develop asparagus berries, which is a dead giveaway).
Are these one or two year crowns?
Bud S on May 27, 2017
BEST ANSWER: They are one-year-old crowns.
A very silly question but is it one asparagus that grows per crown or will it run and have multiple per crown?
Mai Yia V on May 3, 2021
BEST ANSWER: Asparagus plants are long-lived and vigorous. Over the years, you can harvest more and more as the plant continues to multiply. It will run.

Can strawberries and asparagus be planted together?
Brenda J on Feb 13, 2021
BEST ANSWER: We appreciate you reaching out to us. Yes they can be planted near each other. There are two main crops to avoid growing alongside asparagus: Alliums. Alliums like leeks, garlic, and onion sharing the soil with asparagus are said to stunt its growth. That doesn't mean you have to choose between them: Just plant any alliums a good distance away from asparagus beds and they'll be fine

If you have any further questions please don't hesitate to reach back out to us. Have a great day!
Is this perennial?
Phowarth on Feb 9, 2021

Very Good
I ordered these crowns 2 years ago & this is my first year that I could eat these tender asparagus. I am getting an abundance from 12 crowns. They are very sweet to eat right out of the ground. I can't wait till next year because they are growing by leaps & bounds. This is awesome asparagus, the only problem is waiting 2 years to eat it, but it's worth the wait. Follow planting & fertilizing directions & you won't be sorry!

Easy to grow, and delicious
I have been growing Jersey Knight asparagus for several years. I have not grown other varieties, I chose this one as we live in the mountains of Idaho and have heavy soil, and J.K. is said to be cold-hardy and tolerant of clay soil. The spears are big, and some of them are rather short compared to commercially sold spears. Some are quite long though. The flavor of fresh-picked home grown asparagus is far, far superior, so sweet and tender! I get a large pot of water to boiling, then drop in the asparagus and put on the lid. I turn off the burner and leave the pot on the hot burner, 4 minutes for large spears, 3 for medium-sized ones. This cooking method is gentle, and works great for broccoli too.

Awesosme Asparagus!
Planted my Jersey Knight Asparagus 2 years ago and absolutely cannot believe how well it has done. I did not lose one crown and I get comments all the time on how big and beautiful the 6-7 foot tall ferns are ( since I have had to wait for it to get established to pick it), and no one can believe they are from Asparagus. I couldn't resist and did go ahead and pick some spears this spring and the taste was out of this world! The stalks on the ferns this spring are huge and I expect an exceptional harvest next spring. Thank you Stark!
