In the first year asparagus cannot be harvested, in fact it is not necessary to damage the shoots to let them grow and flourish. At the end of the second year, some shoots can be collected, but do not overdo it and pay close attention. Arriving in the third year we will be able to collect them a little at a time, choosing the ripe ones. It is important not to let them ripen too much, to prevent them from becoming fibrous. The harvest varies from four to six weeks between spring and summer. You must necessarily take those that have reached fifteen centimeters, cutting them at five centimeters from the earth. During the whole cultivation the cleaning of the weeds must be done. Preventing straw, twigs and compost with mulch will prevent you from wasting too much time.
How much to irrigate the asparagus
Growing asparagus is a job of constancy, during the first years, it will not be possible to have a harvest and it will be necessary to fertilize, irrigate and hoe the soil. As for irrigation, it must be abundant during decanting and rooting. Subsequently, it will only be necessary to keep the soil moist, avoiding water stagnation, which often causes rot and parasitic fungi, which are dangerous for the plants. In fact, asparagus has no special needs, but especially in the first years after sowing, it needs to be constantly watered during periods of drought and every time, however, the soil is dry. It is a very long-lived vegetable, so it is advisable to keep it in mind when deciding where to plant it. Asparagiaia will in fact last several years.
How to fertilize and fertilize
At the beginning of spring it is advisable to mulch and fertilize the soil, having previously taken care of airing the soil around the plants. This operation guarantees the necessary humidity. With the arrival of winter, indicatively in November, it is necessary to fertilize again using manure and soil. Arrived in the third year, after the first harvests, it will be necessary to cover the plants, adding compost of organic origin. Every autumn, instead, it is necessary to clean up the asparagus, eliminating completely the dry stems with a small knife. Weeds will be removed constantly by hand or with herbicides. Plants can reach two meters in height, so supports must be used to prevent them from breaking.
Exposure, diseases and possible remedies
Asparagus plants prefer sunny places, so they should be planted in sunny places and ventilated, avoiding water stagnation and too much humidity. They should be sown during the spring, burying the seeds just below the surface. It is necessary to sow in parallel rows, maintaining a distance of about forty centimeters. Subsequently sowing, it becomes essential to compact the surface of the soil gently, with your hands or with a tool. Plants can be attacked during every moment of growth, from pests such as insects or fungi. The most common animal parasite is the asparagus beetle, which can be eliminated using diatomaceous sand. As for the risk of fungi, they stick to the roots and must be eliminated using pesticides.
