OhioStateExtension.gifAsparagus is a perennial that should produce for 15-20 years. Site selection should begin at least 1 year prior to planting in order to properly adjust soil pH and to eliminate serious perennial weeds. Select soils that are well drained and deep, such as sandy loams or well-drained loams. It is desirable to plant where asparagus has not been grown before in order to eliminate certain insect pests. However, this practice may not significantly reduce the incidence of fusarium root rot, because new fields are easily contaminated with the disease.

Rhubarb is a hardy perennial in which the petioles or stalks are used for pies, sauces or desserts. Old crowns or rootstocks are divided so that each has a few buds or eyes. Plants from seed take much longer to mature and are variable in growth and vigor.

Harvest 3-4 weeks the second year after planting and increase to 6-8 weeks as the crowns become mature in later years. Maintain healthy leaves on the plantings after the harvest season. Remove seedstalks as soon as they appear, because they remove energy from the crowns.
