Fertilizing Asparagus Plants
Fertilizing is an excellent way to replenish the natural nutrients in your plant’s soil. For asparagus, have your soil tested to determine phosphorus and potassium needs. Asparagus usually likes a balanced fertilizer of 5-10-10 or 8-24-24.
NOTE: This is part 6 in a series of 11 articles. For a complete background on how to grow asparagus plants, we recommend starting from the beginning.
The first 3 years in spring, apply a well-balanced fertilizer. Starting the fourth year, delay application until June or July (immediately after harvest). This approach encourages vigorous growth of the “fern,” which produces and stores nutrients in the roots for next year’s production season.
