How to Grow Rhubarb Plants

Rhubarb is a perennial garden plant that produces edible stems. Since it is a perennial, it is often planted in the back of garden beds or alongside perennial flowers so it does not interfere with annual garden cultivation. Rhubarb is a low-maintenance plant that only requires moist soil. Rhubarb does not have common pests or diseases that you must prevent or treat and does well in most soil types.

Instructions

    • 1

      Select a planting site that gets full sun, which is at least eight hours daily. The soil should drain well. Edges of garden beds are good sites because the rhubarb will not interfere with annuals planted in the main portion of the bed.

    • 2

      Remove all weeds from the planting site. Cover the soil with a 3-inch layer of compost and till it into the soil with a shovel or tiller at a depth of 12 inches. Do this in spring, after the last frost.

    • 3

      Dig a hole in the planting site that is twice as wide as the rhubarb's container and just as deep. Space the holes 18 inches apart for multiple plants.

    • 4

      Remove the rhubarb from its container and lower it into the hole. Firm the soil around the base of the plant and water until the soil settles.

    • 5

      Lay down a 3-inch layer of organic mulch, such as straw, around the plants to keep weeds down. Water frequently enough to keep the soil moist throughout the growing season.
