Asparagus spears peeking through the earth are one of the first signs that spring is here! A farm favorite, and an early perennial, it is the gift that keeps on giving.
When we purchased the farm in early spring of 2013 we were lucky to have a few surprise plants, still left by the garden, to get us by until our new plants were established and well on their way. Once planted, and if cared for, asparagus plants will produce for 15-20 years.
It is important to choose asparagus crowns that are from a reputable distributor or trusted local producer. Invest in healthy plants and you’ll be rewarded for years to come. Asparagus plants take 2-3 seasons before full production but 2-3 year old crowns are available to purchase if you are eager to get a head start. I have had success with planting both younger crowns and 2-3 year old crowns.
I purchased my crowns through Nourse Farms. The varieties we chose were Jersey Night, Mary Washington, and Purple Passion. When selecting your asparagus choose varieties that are well suited for your area. Online information is plentiful depending on which zone you live in or you can check with your local extension office.
Soil Location and Preparation
Select a location that has good drainage and plenty of sunlight. Asparagus prefers a pH range of 6.5 -7.5. You can amend the soil by applying lime if too acidic or sulfur if the soil is too alkaline. Prepare the soil by removing any weeds, as asparagus does not do well when competing. I suggest mulching to keep the weeds at bay.
When you receive your crowns make sure to keep asparagus roots dry and do not soak them. The sooner you can plant them the better, but remember it is springtime and Mother Nature does not always cooperate. Store the crowns in a cool dark place like a basement, root cellar, or garage until you are able to plant.
When you are ready to plant furrow 8” – 10” and spread compost in the bottom of the trench. Separate the asparagus roots like a mustache, spacing 10” – 12” apart, with the crown facing upwards. Make sure the roots have plenty of room to spread out and flourish. Cover the crown with 2” – 4” of soil. As the asparagus plant grows you will continue to add earth to the trench until it is filled, allowing the fern to stay above the soil. The ferns will dry and wither as fall approaches and after winter you will cut back and discard. If all goes well you will be able to harvest that spring and the following season you can enjoy the full abundance of your asparagus.
