What is the one gallon start for 1799 what does it include?
Stormvet1st on May 19, 2016
When can asparagus sets be planted ?
Alexander W on May 12, 2016
BEST ANSWER: We plant in the spring and don't start harvesting for a couple of years. Only cut until the end of June, then let grow for until the next spring.
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.
How deep should a raised bed be that would support asparagus?
Willie S on Apr 7, 2016
BEST ANSWER: Not positive but mine is only about 8 inches and they are very happy.
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.
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 soil.
Is there any asparagus variety that can be harvested before 3 years?
Shirley K on Mar 21, 2016
BEST ANSWER: No, however if your plants look good in 2 years you could start to harvest them.
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.

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.

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.

I enjoy asparagus very much and I am still waiting for a more mature crop. I know it takes a couple of years. I fertilize regular with an organic substance and can hardly wait for a bountiful harvest.
