Growing Rhubarb – An Easy Perennial

Growing rhubarb is so easy, everyone should have a  plant or two! As I was walking through the garden this weekend, I noticed that the rhubarb plants were up – when rhubarb emerges, it’s a sure sign of spring!

Rhubarb is super easy to grow, comes back every year, and makes fantastic pies, custards, and crisps! But, you actually grow it to eat the stalks and the flower heads need to be cut off.

Here’s all you need to know to grow your own tasty, perennial rhubarb:

Where Rhubarb’s Grown

Rhubarb can be grown just about anywhere, but prefers full sun and needs a well-drained location. Several years ago I planted some in a protected nook, and it died, so three years ago I put some in one of my sunniest locations, and it’s thriving.  I like to tuck in a plant in here and there in flower borders too; they provide some nice foliage contrast.

How to Start Growing Rhubarb

Rhubarb is grown from corms (root divisions), and in most regions these should be planted in early spring.  In mild regions, they can also be planted in the fall.  The corms should be planted about 3 or 4 inches deep with the buds a couple of inches below the soil surface.  Many seed suppliers carry rhubarb or you can get some from a friend’s rhubarb patch.

First Year Care

The first year after planting rhubarb, none of the stalks should be harvested. The plant(s) should be allowed to use all its energy establishing a strong root system.  Removing stalks in the first year causes the plant to expend energy for leafy top growth instead.  Feed the plant(s) by top dressing with compost in fall and spring.

Ongoing Care For Growing Rhubarb

You can start harvesting rhubarb the second year after planting but be sure to cut off any flower stalks immediately.  The plant will expend a considerable amount of its energy-producing flowers, but since we want the stalks, the flowers should be removed.  Continue top dressing with compost in spring and fall as rhubarb plants will continue producing for many years (perennial) once established.

Harvesting Rhubarb

Harvest rhubarb by grasping a stalk and twisting sideways to remove the entire stalk.  Don’t use a knife to cut rhubarb thereby leaving parts of the stalk still attached to the crown.  This may encourage rot, and rot is one of the few serious diseases afflicting rhubarb. 

You can harvest for about six weeks each spring, but no more than a third of the stalks should be harvested at a time.  Be sure to leave the plants enough foliage to sustain themselves through the winter.  Rhubarb leaves should never be eaten; they are poisonous. Only the stalks should be eaten. After harvesting, besides cooking immediately, the stalks can be cut into pieces and frozen for use later in pies and crisps.
