Although the different varieties are called early or late, asparagus are usually eaten in spring. Follow our advice to get a nice harvest and avoid disease.

There are 2 types of asparagus, white asparagus and green asparagus. Both are grown in the same manner.

During the months of February to April, it is important to plant asparagus in rows, preferably aligned with dominant winds.

Asparagus is demanding and it is necessary to fertilize the ground beforehand.

  • Sandy soil is better because it warms up faster.
  • Avoid wet soil.
  • Keep plants about 20 to 24 inches (50 to 60 cm) apart and rows 5 feet (1.5 meters) apart.

Plant asparagus thanks to young root clumps grown from seeds, called “crowns”.

  • The first year, dig a trench 1 inch (2 to 3 cm) deep and place the crowns at the bottom of it.
  • Cover with an inch (a couple centimeters) of soil mix or finely broken good soil.
  • and then fill in with garden soil.

If you’re preparing seedlings, wait for a year before putting them in place.

Growing asparagus:

Asparagus needs 2 years to grow since they cannot be harvested during the first year.

To speed things up, it is possible to purchase plants that are already 2 years old.

  • The first year, the crowns are covered with about 1 inch (2 to 3 cm) of soil.
  • The second year, the crowns are covered with about 6 to 8 inches (15 to 20 cm) of soil.

Once well settled-in, you’ll be able to harvest your asparagus for over 15 years.

As for watering, asparagus needs water on a regular basis but hates sitting water.

Harvesting asparagus:

Asparagus must be harvested while still tender, and you cut it off with an asparagus knife.

The best time to harvest asparagus is from April to June. Shoots are harvested with a long blade-tipped tool called an asparagus knife.

  • When the shoot points its tip out of the sand, this shows it is time to harvest the asparagus (If you missed it, better to let it grow into ferns).
  • Sink the blade deep into the soil to cut the shoot off as low as possible and have as much asparagus as you can.
  • Green asparagus are more shallow and a simple knife is enough to harvest them.

Tip: It is best to wait a full 3 years before harvesting your asparagus, to let the plant develop during the first years of its life.

All there is to know about asparagus:

This vegetable has high vitamin C levels, but its delicate and subtle taste and its fine flesh are what make it delicious.

Asparagus grown today were bred from an ancestor called medicinal Asparagus.

The taste of asparagus essentially depends on the type of soil and organic matter content.

Clay and loamy soils will give it a rather bitter taste.

There are several kinds of asparagus:

  • Green asparagus: definitely the finer tasting one, it doesn’t need to be peeled.
  • White asparagus: rather common, it is thicker and can only be eaten after peeling.
  • Purple asparagus: a rare variety that is closer to the green asparagus.
  • Wild asparagus: thin and delicate, it is perfect in mixed salads.

To taste them at their best, eat them quickly after they’ve been cut.

Smart tip about asparagus:

Add compost in fall to increase availability of nutrients.

    Hello Pierre! If your asparagus are sticking out of the soil as tall as a toothpick, you can already harvest a a few for fun, but it would be best to wait another two years for the plant to grow. If its your first time, try and dig some soil out carefully to have an idea of where the shoot is starting off from. If you wait too long the shoots will get fibrous. It’s ok to harvest until end of June but after that you must let the plant live from its leaves to grow strong for next year.

    Hello it has been one year since I planted my asparagus, now they are like a toothpick. Shall I cut them at soil level or let them be? Thanks for your help.
