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

P = Plant in the garden.

  • 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.

My leaves are going yellow, query cause? Also what ferterliser do you give the plant?

Hi Monica, Given you're in an Australian temperate climate, I'm guessing you've had the same cold wet weather as the rest of us. I believe it's the cold temperatures that are causing the leaves to go yellow. Just pull off the yellow leaves and let the plant put its energy into new leaf stalks. Any fertiliser that is high in nitrogen is fine. I like to use well-rotted chicken manure, Rooster Booster (pelletised chicken manure) or even dynamic lifter. But even compost is just as fine to use. Nitrogen is what encourages leafy growth, so it's perfect for rhubarbs as it's the leaf stalks we want. I've read that it's nearly impossible to overfeed a rhubarb, as they are quite heavy feeders.

My rhubarb has healthy leaves but very short stems. How can I encourage the stems to grow much longer?

is it best to snap the stems of or snip them

Pull them off at the base of the stalk. If you cut them, it leaves an open 'wound' for disease to get into the rhubarb plant.

We have rhubarb growing but the stems are large but still green how long before the turn pink so we can pick them?

There is a variety of rhubarb that has green stems and it actually is milder than the red stem variety. So pick and enjoy.

Go for trays. I have never heard of rhubarb by seed always corm. In trays at least you can keep an eye on it and know what is happening throwing seed into the soil sometimes is taking too much of a chance with birds, mice, rotting etc..especially with odd things like this.

Hi I have just found the site and have a packet of seed, do I plant direct or trays.
