Rhubarb is a delicious and decorative vegetable commonly eaten as a sweet treat. It is a perennial plant that thrives in cool to warm conditions and is a great addition to any Australian garden. With its big leaves and juicy stalks, rhubarb requires a lot of water and plenty of space to grow. In this guide, we will explore the steps to grow and care for rhubarb in Australia, including planting, watering, feeding, and harvesting techniques, to ensure a bountiful and tasty harvest.
| Characteristics | Values |
|---|---|
| Temperature | Grows best in cool to warm conditions, with reduced vigour during cold winters. |
| Climate | Suitable for all climatic zones. |
| Sunlight | Full sun to part shade. On hot days, rhubarb will benefit from some shade. |
| Soil | Deep, well-drained, and rich in organic matter. Add compost, well-aged cow manure, and fertiliser before planting. |
| Planting | Grown from crowns or seeds. Crowns are the preferred method as they yield a harvest in the first or second season, whereas seedlings may take several years. |
| Spacing | Do not crowd the plants. |
| Watering | Requires plenty of water. Keep the soil moist and give a deep soaking once or twice a week in hot, dry weather. |
| Feeding | Feed regularly with blood and bone, pelletised poultry manure, worm castings, compost, or liquid fertiliser. |
| Harvesting | Begin harvesting in the second year. Harvest by pulling stalks away from the central crown—do not cut. |
| Pot size | Pots should be at least 50cm wide and deep with good drainage. |

What You'll Learn
Choosing a spot: full sun or part shade
When choosing a spot to grow rhubarb in Australia, it's important to consider both sunlight and shade. Rhubarb grows best in full sun, but it can also tolerate part shade. If you live in an area with hot summers, it's a good idea to provide some shade for your rhubarb, especially during the hottest part of the day. A simple solution is to set up a temporary frame with a shade cloth cover on hot days. Alternatively, you can consider a more permanent shade structure or plant your rhubarb in an area that receives dappled light.
If you're growing rhubarb in a pot or container, make sure it's at least 50cm wide and deep to allow room for the roots to grow. You can grow rhubarb in a smaller pot, but you'll need to be careful not to let it dry out. Choose a premium potting mix specifically designed for vegetables and herbs, such as Scotts Osmocote® Plus Organics Tomato, Vegetable & Herb Potting Mix.
When planting rhubarb in the ground, select a spot in your garden that receives full sun to part shade, depending on your climate and the plant's needs. Prepare the soil by improving its drainage and adding organic matter such as compost, well-aged cow manure, or fertiliser. Rhubarb thrives in deep, rich soil that is well-drained to prevent the crown from rotting.
Keep in mind that rhubarb is a perennial plant, so once it's established in your garden, it will continue to produce edible stalks for many years. With the right care and conditions, your rhubarb plant will reward you with an abundance of thick, juicy stalks that you can harvest and enjoy.

Soil preparation: well-drained, rich in organic matter
Rhubarb thrives in deep, luxuriant soil that is rich in organic matter and well-drained. To prepare the soil, add plenty of compost and well-aged cow manure before planting. Avoid covering the crown with mulch or compost. Instead, mound the soil to improve drainage or grow in raised beds if your soil is heavy. Rhubarb is a heavy drinker, so water it regularly, but make sure the soil is well-drained to prevent the crown from rotting.
If you're planting in a pot, choose one that is at least 50cm wide and deep, and fill it with a premium potting mix. A good potting mix should contain fertiliser and improve drainage. Yates Potting Mix with Dynamic Lifter is a good option. If you're planting in the ground, loosen the soil and mix in a soil improver and plant fertiliser, such as Yates Dynamic Lifter Soil Improver & Plant Fertiliser or Scotts Performance Naturals Soil Improver and Scotts Performance Naturals All-Purpose Organic-Based Fertiliser.
Rhubarb grows best in cool to warm conditions, and the stalks colour better in cooler temperatures. It will withstand slight frosts, but heavy frosts may cause dieback. In warmer areas, consider providing some shade for your rhubarb, either with a temporary frame and a shade cloth or a more permanent shade structure.

Planting: crowns or seeds
Rhubarb can be grown from crowns or seeds. Crowns are the part of the plant under the ground and consist of a rhizome and a bud. Crowns can be purchased from a local nursery or garden centre and planted in winter. Seeds, on the other hand, should be sown in spring or summer.
When planting crowns, ensure the roots are under the soil but the 'eye'—where the shoots will emerge—is at ground level. The recommended depth is to have the top of the crown 3 cm under the soil. However, some sources suggest planting the top of the crown slightly above the soil to reduce the chance of rotting. Crowns should be planted about 90 cm apart.
If growing from seeds, sow them into punnets filled with a premium potting mix and keep moist until they germinate. When the seedlings are 6-7 cm tall, transplant them to a larger pot.
Whether starting with crowns or seeds, it is important to choose a sunny or partially shaded spot with good drainage and rich, well-prepared soil. Improve the soil by adding compost, well-aged cow manure, and organic fertiliser before planting.

Watering and feeding: keep moist, feed regularly
Watering your rhubarb plants is critical as they have big leaves that require plenty of water. Ensure that the soil is moist and give the plants a deep soak once or twice a week during hot and dry weather. To retain moisture, cover the soil with an organic mulch such as compost, straw, or sugar cane. Avoid overwatering, as this can cause the crown to rot, especially if the soil is not free-draining.
Feeding your rhubarb plants is equally important. For the highest yield, feed your plants regularly with blood and bone, pelletised poultry manure, worm castings, or additional compost. You can also supplement with a fortnightly application of seaweed solution and fish emulsion. Additionally, feed weekly with liquid plant food during the growing season. Rhubarb requires substantial fertilising to maintain growth and produce high-quality stalks.

Harvesting: from year two, pull stalks, don't cut
When harvesting rhubarb, it is important to remember that only the stalks are edible. The leaves and roots are poisonous and should be discarded or composted.
Rhubarb should not be harvested until the plant has been in your garden for at least two years. When harvesting, pull the stalks away from the main stem with a quick tug—do not cut them. Exposed stems can cause rot. Hold the stalk towards the crown and twist and pull so that it comes away cleanly. This tells the plant to regrow a new stalk, giving you a more fruitful harvest and a healthier plant.
When gathering your rhubarb, never harvest all the stalks from a plant at any one time. Always leave at least half of them for the plant to continue growing. You can harvest continually to promote new growth. Remember that the stalks do not need to have turned from green to red to be ready for harvest. The best time to harvest is during late spring and summer. After harvesting, it is best to let the plant be so it can regrow and recharge to survive the winter.
To conserve moisture, cover the soil with an organic mulch, such as compost or straw.

Frequently asked questions
You can grow rhubarb from crowns planted in winter or early spring, or from seeds sown in spring or summer.

Rhubarb has big leaves that need plenty of water. Keep the plants moist and give them a deep soaking once or twice a week in hot, dry weather.
It is recommended to wait until the second year before harvesting rhubarb. When harvesting, pull the stalks away from the central crown—do not cut them.
Divide rhubarb crowns every 3 to 5 years to reinvigorate the plants and get new crowns. Dig around the clump in winter, select healthy young shoots, and cut them from the main clump. Replant the new divisions straight away.
