Great value

I really like asparagus

Start has excellent plants and this is a good time tested variety of asparagus.

Quality product at a great price.

What is the one gallon start for 1799 what does it include?

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?

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.

When can asparagus sets be planted ?

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 there any asparagus variety that can be harvested before 3 years?

No--but the crowns that came from Starkbros are at least a year old. Allow two growing seasons for the plants to establish themselves. As long as the plants have been at least lightly tended to, you should be able to harvest in your third year--two years after you plant.

Is this similar to Miller's Super Male variety?

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 old are the roots?

Thank you for your question. Our asparagus crowns come in a package of 10, which are one-year-old crowns.

Are these plants both male and female or just male? What is predicted life of bed once producing( after three years )?

I also get a few females. How can they tell the difference in a one year old root?-They can't.
But I have not noticed any difference in production anyway. Just try to remove the red berries and dispose them or plant them seperately for more home grown 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 ?

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)

How deep should a raised bed be that would support asparagus?

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?

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.

3rd year - moderate harvest - zone 5b
planted in 2022, moderate fertilization, zone 5b, sandy soil, mulched. Got about 5 groups of plants running, harvested about 5 servings from them in 2025 (this year) so far (End of April). Tried not to harvest too much this year.

Good stuff.
I plant them deep and with the proper splash of water, they jump out of the ground. I was raised on a Cherry & apple orchard from 3 1/2 till I left for the Special Forces @ 18. We always had a one to 2 acre garden. To me, tomatoes, carrots, sweet Japanese turnips, black berries, rasps, strawberries and more were meant to be eaten while sitting between rows. That goes for sweet asparagus as well.

Love asparagus
Planted my starts on 4/21 and they grew really well. On the growing season of 2022 I didn't harvest any and they grew 4 feet tall, in September I cut them down and bedded them for the winter, they were absolutely full of seeds, hope to harvest a big bounty in the spring of 2023. I also put a thin layer of mulch on the whole bed.....

Thriving in the first year
This is the first year of planting the crowns - each one came up with one or two stalks and did well all summer! I won’t harvest for another 2-3 years but so far the plants look really healthy!
