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.
When can asparagus sets be planted ?
Alexander W on May 12, 2016
BEST ANSWER: As soon as you can dig a hole in Spring. If the roots are dormant, they can also be buried in fall after everything else is dormant. I wouldnt plant them any later in summer than 120 days before your first frost.
Is this similar to Miller's Super Male variety?
Brian S on Apr 3, 2016
BEST ANSWER: Similar in that they're primarily male asparagus plants (the most productive). Jersey Knight is a highly productive variety selected for its large spear size.
with the asparagus, whats the difference between 1 gal. small stark container and the bare root?
John W 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.
Is there any asparagus variety that can be harvested before 3 years?
Shirley K on Mar 21, 2016

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.
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.
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
BEST ANSWER: Hi Jeff,
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)
Are these one or two year crowns?
Bud S on May 27, 2017
BEST ANSWER: They are one-year-old crowns.
How many spears, or pounds, will 1 (one) asparagus plant provide at harvest?
finernfrogfur on Dec 1, 2016
BEST ANSWER: Thank you for your question! Jersey Knight is a prolific producer and will give you nearly a pound per plant. Don't pick any spears the first year and be sure not to trim off the ferns; that's how the plant makes food for next year.
Are these plants both male and female or just male? What is predicted life of bed once producing( after three years )?

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.

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!

big healthy plants
I ordered and planted mine last summer. Had to move them early this spring but it hasn't seemed to slow them down at all. The plants are large and healthy, and I'm planning to harvest lightly next spring.

Check back with me in a year.
These grew like weeds into a fen-like plant last year(I am an amateur so I have no idea what to expect). Per what I read on the internet, I just let them grow and in a few years I should have some asparagus. Look like they weathered the 300 inches of snow we received this past winter as I looked today and saw some spear popping out of the ground. Looks like a winner!
