An asparagus is a hardy perennial that can produce delicious green spears for up to 20 years (when planted in the ground).
Spears are harvested in the third year of growth when the plant is established.
Each plant produces about one-half pound of spears per year after establishment.
The first two years produce spears that open on the top and resemble an eye-appealing fern but are not edible.
If you have a lot of garden space, then growing a lot of asparagus should be no problem. However, you may want to grow asparagus in containers:
I just couldn’t commit to putting them in the ground, so I am taking the risk! The last thing I want to do is put them in the ground and then have to dig them up if I decide to move.
My family loves asparagus, but we always get sticker shock when we go to the grocery store. When I realized that I could grow them, and I did not have to start from seed and wait for three years, I decided it was worth a try.
Learning how to grow asparagus in containers eliminates most weed problems. However, it doesn't matter whether you start from seed or these two year crowns, you need patience. Even though I am growing two year crowns, I still have to wait a year before edible shoots can be harvested.
It takes two years for plants to settle in and build up enough reserves to produce quantities worth harvesting.
This was my reasoning behind purchasing 2 year old crowns. After giving them a year to settle in, I am hoping that by the next Spring I should be able to harvest some asparagus shoots.
There are a few things to consider when raising asparagus in containers:
Keep in mind that asparagus that are planted in the ground can grow very deep. Choose a container that will simulate soil depth. Your container needs to be about 18 inches (or more) tall, and at least a foot wide. I placed only one crown in each container.
The container should be:
Appropriate containers include:
These first shoots will develop into mature plants so they can gather the energy needed for next Spring’s harvest
Cut the asparagus plants down to the soil level with a sharp knife in late fall.

I love your step by step instructions with pictures. I have wild asparagus outside and now I’m thinking of trying indoors too. Thank you for your site. Shawn on May 21, 2019:
Don’t know what happened here but thanks for your site!

They stay outside during the winter. The plants go dormant.

What do you do with the pots in the winter?
Can they stay outside here in NJ or do they have to be stored inside till next spring

Thanks for the detailed article about planning Asparagus!
Your pictures are excellent with well explained procedure. I like the idea of using pots since I don't have much land space for plantations.
Thanks for sharing this!
