When to plant asparagus plants?

When you are growing asparagus you can plant asparagus roots or their crowns in August, 2 feet apart in rows of about 3 to 4 feet apart. You should plant at least 17 plants, do not expect a full plant in the next two years but this depends on the vigor of the crowns.

Seed grows much easier than the roots or the crowns but if you use the seeds you should not harvest the spears until the fourth year. After a year, you can choose the strongest seedlings and transplant.

How To Plant Asparagus?

Plant the crowns firmly in a trench so that they are about 8 inches below the surface and cover with 3 inches of soil. The soil used in growing asparagus is very different from many other soil compositions. Asparagus needs sandy, well drained, neutral soil (pH of 6.5-7). This soil needs to be mixed with plenty of kraal manure and compost.

While growing the plant you should water deep each week if there is not enough rain. Midsummer you need to apply ammonia nitrate, it has to be done when the soil is still moist. Every winter you need to cover the top soil with the same mixture.

Don’t forget to add fertilizer 6:3:2 to the mixture as well. It is important when growing asparagus you should stop watering the plants during winter months if you are in the Southern African region it means you stop watering in April till mid-July.

Harvesting Asparagus Plants

Harvesting asparagus spears has to be done using one specific special made rod, sharpened and flat at one end which is inserted below the soil, sever the stalks as soon as the tips break the surface.

For the first season, the spears need to be cut for only two to three weeks then leave the tips to grow into greenery. Mature plants can be harvested for longer periods of about seven to eight weeks.
