| − | The vegetable known as Asparagus, is the specie '''''Asparagus officinalis''''', of the ''[[Asparagus (genus)|Asparagus]]'' genus, which has many [[Asparagus (genus)|other species]]. Once established, this is a very reliable, long-term perennial that will produce crops year after year. It takes 2-3 years for plants to reach full production. After that period a good spring crop should be produced for the next 10-15 years. Plants take a fair amount of room, producing grand and feathery branches, which are very ornamental. Plants make a good background for other vegetables or flowers, and look good along a sunny fence.

| − | Seeds planted in the spring become strong plants in the first season, but most people buy roots. Seedlings as well as plump roots bought from the store should be planted either in the fall/winter (mild climates) or early spring (cold winter climates). Plant in 1ft wide, 8-10in deep trenches, with themselves trenches 4-6in apart. Manure-enriched compost/soil should be heaped loosely at the bottom of the trench, and watered in well. Plant roots/seedlings a foot apart, in such a way that tops are 6-8in below trench top. Roots should be evenly spread, and covered with 2in of soil and given more water.
| |
| − | | |
| − | Fill in trenches as plants grow, being careful not to cover growing tips. Water with a deep soaking whenever soil near roots starts to dry. Do not harvest any spears the first 2 years to allow the plants to gain strength. Cut stems to ground when they die in the fall, or in the spring if you live in cold-winter areas (to help protect roots from snow).
| |
| − | | |
| − | The third year you can harvest some of the shoots during the first 4-6 weeks of production, but be very careful to stop if they begin to get noticeably thinner. After that time frame, stop harvesting to allow the plants to grow and gather strength for the next years crop. Cultivate and feed during the year, and water regularly.
| |
| − | | |
| − | After the third year you can harvest for 8-10 weeks, when the spears are 5-8in long. Slice into the stem with a knife at ground level at a 45 degree angle.

| − | ===Propagation===
| |
| − | Seeds planted in the spring. Traditional varieties will produce seed, some varieties known as "all-male" have almost all male plants which produce no seed.
| |
| − | | |
| − | ===Pests and diseases===
| |
| − | Asparagus beetles should be hand picked off the plants during harvest season, and knocked off with jets of water. Growing with tomato plants helps reduce these pests.
| |
| − | | |
| − | ==Cultivars==
| |
| − | White and purple varieties exist, as do some varieties with virtually no female plants.
| |
| − | | |
| − | Popular cultivars include:
| |
| − | *'Martha Washington' - traditional type
| |
| − | *'Jersey Giant' - "all-male" varieties which do not produce seeds, allowing for better crop production.
