Asparagus is a true spring refreshment. It is a perennial vegetable, that is, it reaps year after year. Once established, you can expect 10 plants to produce about 3 kg of stems in six weeks to 20 years.

The best asparagus variety
How we try asparagus
Our taste team, trained in identifying and rating each flavor, evaluated how tasty the spears were both uncooked and steamed (the best cooking method to keep the color). They were looking for bright and fresh spears that were straight, solid, the same size and with stiff tips. Spears should smell of grassy and green colors when uncooked and get a slight hint of beans when cooking. But they lost traces if the taste or smell contained traces of compost. We were looking for varieties with a fresh asparagus flavor, medium sweet, with a bit of bitterness. The stems should be dense but soft when boiled, preferably without wood, granular or astringency.
Prepare the bed
Grow asparagus in well-drained, neutral or slightly alkaline soils free of perennial weeds such as dandelions or in raised beds. Dig plenty of well-digested organic matter such as used mushroom compost. For a faster first harvest in April, plant crowns are crowned annually.
Leave 40 cm between the plants in a row and 90 cm between the rows. Dig a ditch or hole wide enough for the roots to spread and place a crown on a mound 10-13 cm below the surface of the soil, with the roots radiated to the sides. Cover loose ground. It is best to leave the first large crop until the plants are three years old.
Take care of your plants
In March, apply a balanced fertilizer or mulch with well-digested organic matter to a set bed. Keep the asparagus herb loose; It is best to weed by hand as you could damage the shallow roots with hair.
How and when to harvest
Harvest in: April June
Cut the stems when they are 4 inches long and have a tight bud. Use a sharp knife and cut an inch below the ground. Stop cutting spears from biennials in May to allow the ferns to develop and in mid-June for rooted plants.
In the fall
In October or November, cut dead squares to the ground and clear the trash to remove the asparagus beetles during hibernation.
Common growth problems
Asparagus beetles are small yellow-black beetles with red heads. Buff your larvae eat the squares and weaken the plants. Choose them from the beginning of May.
