  • P = Plant crowns
  • Easy to grow. Plant pieces of rhizome or roots 8 - 10 cm (3 - 4 in.) deep. Best planted at soil temperatures between 41°F and 68°F. (Show °C/cm)
  • Space plants: 35 inches apart
  • Harvest in approximately 1 years. You will have a stronger plant if you leave it for about a year before using..
  • Compatible with (can grow beside): Brassicas (Cabbage, Broccoli, Cauliflower, etc)
  • Young rhubarb
  • Rhubarb Plant

Rhubarb is easy to grow in cool climates and is a perennial. Rhubarb can be left in the ground and will return a crop for many years, at least 10 to 15 years (We have one that is more than 20 yrs old). Rhubarb is quite a hardy crop but the crown will rot if in heavy wet clay soils. It can cope with dry periods. Plant in good soil and remove as many weeds as possible. Do not disturb rhubarb roots when cultivating round the plant. Better in cooler climates, but can be grown in shady areas of warm climates. You can lift and divide rhubarb to make more plants. It is best to do this when the plant is dormant (or at least less actively growing) in winter or late autumn. It is best to wait until a plant is about 5 years old before dividing the crown but it can be moved at any age. Some of the root structure will be damaged when lifting it, so stalk production will not be so good for a few months. If you have mild winters and your rhubarb is still producing new stalks, you can continue to pick it. Although rhubarb is used in desserts and jams, it is considered a vegetable because the stalks are used not the fruit.

NB: Do not eat the leaves or roots as they contain oxalic acid which is poisonous. They should not be fed to poultry or stock either.

Remove flower stalks as they appear as the plant will stop producing leaf stalks when flowering.

Rhubarb can be 'forced' by covering dormant crowns with clay pots or a cloche in early spring.

Culinary hints - cooking and eating Rhubarb

Pick stems about the thickness of your finger. Large stems will have tough 'strings' down the length of them.
Use in pies, crumbles, fools and jams. Rhubarb goes well with orange.
Will usually need sweetener.

a. Rhubarb leaves - yellowed/dead leaf edges (removed from plant 30 Jan) b. Rhubarb - overall stunted growth & poor stem growth; rhubarb should be in abundance this time of year planted in raised beds good high organic soil Ph 7.6

Any general fertiliser is good.

Hi I’ve got a rhubarb plant I planted at the end of sept/early oct. Several of the larger leaves have turned yellow (about 3) and about 3 new baby stalks have turned yellow. There are still about 10 large green healthy leaves on there. Is there something I’m doing wrong?

The larger leaves could be just old ones. The new leaves could be lack of fertiliser.

I live in Dallas, TX and I would like to plant some rhubarb, cauliflower, cabbage, carrots, and beets. When do i plant these and can I plant them in a shaded part of the yard?

You will have to look up on this website, each different vegetable to see when to plant. Veg general need sun and lots of it.

My plants are healthy but the stalks aren’t very red in colour? And red only halfway up the stem?
25 Nov 23, (South Africa - Summer rainfall climate)
That is normal.

Can I successfully grow Rhubarb in Miami if I plant it in a pot to keep it out of the direct sun in the summer? What variety would grow best?
