To grow asparagus it is best to buy roots that are 2 or 3 years old, which is the period after which you can gather the product. Asparagus grows in most soils, but the soil must have good drainage and be pest-free, so it must be constantly weeded, using pesticides suitable for use in the garden. To create an asparagus patch, during the fall and winter it is necessary to dig the ground, fertilising it well with organic manure. The land where you are going to plant the roots, and thus to create the asparagus patch, should be moist and well fertilized. The asparagus roots should be planted in March. Arrange the seedlings by covering the roots with a layer of 5-7 cm of soil, moving them out towards the edges. Arrange them at least 45 cm apart from each other. Between one row of asparagus and the next it is necessary to leave passageways, since the soil needs constant weeding. In October, cut the yellowed stems and spread a layer of at least 5 cm of manure or compost, then add several inches of soil in the row. The shoots can be cut from the third season of your asparagus patch, cutting obliquely 2-4 cm under the soil, with clean cuts. Shoots are cut from March to June. After that let them grow to produce nutrition in the crown for the next year's crop. The most important treatment for an asparagus patch is therefore the winter manure, fertilizer in spring, and keeping the stems from June onwards, because its organic substances serve as food for the plant itself; and it is important to weed your asparagus patch constantly by hand.
