(Best months for planting Rhubarb in Australia - temperate regions)

P = Plant direct in garden where they are to grow.

  • Easy to grow. Plant pieces of rhizome or roots 8 - 10 cm (3 - 4 in.) deep. Best planted at soil temperatures between 5°C and 20°C. (Show °F/in)
  • Space plants: 90 cm 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 in same bed): Brassicas (Cabbage, Broccoli, Cauliflower, etc)
  • Young rhubarb

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.

I bought Rhubarb plants from Bunnings about 3 months ago, very small and delicate, and they just don't progress. Each time it is windy, or we have a warm day, they seem to wilt and die off. They are in red soil, with horse manure mixed in, and the ph is about 8-9 I think(it's difficult to tell the colour of my PH test kit), sun from 7am till 2pm, and mulched with sugar cane mulch. So much for rhubarb being easy to grow :-( .Anyone got any suggestions?

I put in new rhubarb plants in autumn this year and they are growing really well. When should i harvest them and can we eat them this year? TIA

it is October and I already have long, thick stems on my plants. Are they ok to eat green? Also, it looks like it is starting to flower. What does this mean? Thank you

Yes, I have two rhubarb plants which produce. both in 40 cm pots, well watered and fertilised.

I find my plant is a black stump in the long frosty season, but now September it is happy. My question please is- do I need to wire it over in the bush to protect it from the roos or other critters?

Can you grow rhubarb in pots successfully

just dig in some compost and aged manure then plant the crown. It works well in this climate

I am in Canberra. As a child I ate stewed rhubarb, rhubarb and apple pie, fruit compote with rhubarb. I would like to grow it. How do I get started? Susan
