Asparagus is easy to grow .It can thrive for 15 years or more. Asparagus plants should grow for at least 1 season in the garden before they are harvested.
Asparagus can be grown especially well in cooler regions with longer, colder winters.
Choose a sunny, well-drained site on the edge of your garden where it will not be disturbed by the activity of planting and re-planting other areas.
Asparagus should be planted in the early spring or in the fall when temperatures are cooler. Before planting, add compost and organic fertilizer to amend the soil. Plant crowns with the buds up in the bottom of the furrow, and cover them with 1 – 3 inches of soil. Space the crowns 12 to 16 inches apart within the row. Allow at least 3 feet between the asparagus rows or the next closest vegetable crop. How well you prepare the bed determines the vigor of your asparagus patch for years to come.Good soil moisture is important during the first growing season. Irrigate or water your asparagus enough to wet the soil 8 inches deep every week. Asparagus likes rich, well-drained, non-acidic soil.
Space plants 12 to 18 inches apart. If there are tenacious weeds or grass, treat with an herbicide for use with food crops, or cover the area with black plastic during the summer before planting to eliminate problems in the future.
It is need to wait at least 2 or 3 seasons before harvesting. It may be hard to resist tasting the first spears to emerge, but go easy on the plants until they mature.
Asparagus has male and female plants. Female plants produce seeds—the little red berries can reduce the yield of the plant, as energy is put into seed production instead of back into the root system.
Bent spears are caused by insects feeding or damage from cutting adjacent stalks. The damaged stalk grows normally on the side away from the wound, causing the spear to bend.
A well-drained bed will have minimal disease problems. Black and red asparagus beetles can be a challenge, damaging the foliage and weakening the roots. Usually you can control them with hand picking.
When you harvest spears use a knife. Use one hand to hold the top of the spear you are harvesting. Cut the spear off about one inch below the soil line. Be careful not to cut too deep – it will damage the asparagus crown.
Harvest all the spears that come up during the harvest season. If you harvest asparagus that will be eaten later, wash the spears and place the cut ends in about 2 inches of water. Like fresh flowers, they will keep in the refrigerator for several days.remove the brush (old stalks) and any weeds.
Fresh asparagus spears can be stored a week or more. If you want to put some aside to enjoy in the months to come, blanch them in boiling water for 3 to 5 minutes, douse in cold water, wrap, and freeze.
