How To Grow AMAZING Rhubarb: Tips and Tricks for a Bountiful Harvest

Understanding Rhubarb Biology

To grow amazing rhubarb, it’s important to understand the biology of this unique plant. Rhubarb is a perennial vegetable that belongs to the Polygonaceae family. It is known for its thick, fleshy stalks that are used in a variety of culinary dishes.

Rhubarb Growth Cycle

Rhubarb has a unique growth cycle that is different from most other vegetables. The plant grows from a crown, which is a cluster of roots and stems. In the first year, the plant produces only leaves and no stalks. This is because the plant needs to establish a strong root system before it can produce stalks.

In the second year, the plant will produce stalks that can be harvested. The stalks will continue to grow throughout the growing season, and can be harvested until the end of June. After June, the plant needs to be allowed to grow undisturbed so it can store energy for the next year’s growth.

Rhubarb Planting

Rhubarb prefers to grow in cool temperatures, and it is important to plant it in the right location. The plant needs to be planted in soil that is well-drained and rich in organic matter. It is also important to plant rhubarb in a location that receives full sun.

When planting rhubarb, it’s important to plant it at the right depth. The crown of the plant should be planted just below the soil surface, with the top of the crown exposed. It’s also important to space the plants at least three feet apart to allow for proper growth.

Rhubarb Maintenance

Once rhubarb is established, it requires very little maintenance. It’s important to keep the soil moist, especially during dry periods. Rhubarb also benefits from a layer of mulch around the base of the plant to help retain moisture and suppress weeds.

In the fall, it’s important to cut back the stalks to ground level and remove any dead leaves. This will help prevent the spread of disease and pests. It’s also a good idea to fertilize the soil with compost or well-rotted manure in the fall to provide the plant with the nutrients it needs to grow strong the following year.

By understanding the biology of rhubarb and providing it with the right growing conditions, you can grow amazing rhubarb that will provide you with delicious stalks for years to come.

Choosing the Right Rhubarb Variety

To grow amazing rhubarb, it’s important to choose the right variety for your garden. There are many different types of rhubarb, each with their own unique characteristics and growing requirements. Here are some factors to consider when choosing the right rhubarb variety:


Rhubarb is a cold-hardy plant that prefers cool temperatures. Some varieties are better suited to colder climates, while others can tolerate warmer temperatures. If you live in a colder region, look for varieties like Victoria, MacDonald’s Canadian Red, or Crimson Red. If you live in a warmer region, consider varieties like Cherry Red or German Wine.


Different rhubarb varieties have different flavors, so it’s important to choose one that suits your taste preferences. Some varieties, like Victoria and MacDonald’s Canadian Red, have a sweeter flavor, while others, like German Wine and Cherry Red, are more tart. Consider what you plan to use your rhubarb for – if you’re making pies or desserts, a sweeter variety may be more suitable, while a tart variety may be better for making jams or sauces.


Some rhubarb varieties are more productive than others, meaning they produce more stalks per plant. If you have limited space in your garden, you may want to choose a variety that produces a high yield. Varieties like Victoria, Crimson Red, and Riverside Giant are known for their high yields.

Disease Resistance

Certain rhubarb varieties are more resistant to diseases like crown rot and powdery mildew. If you want to minimize the risk of disease in your garden, look for varieties like Victoria, Crimson Red, or Prince Albert, which are known for their disease resistance.

By considering these factors, you can choose the right rhubarb variety for your garden and set yourself up for success in growing amazing rhubarb.

Preparing the Soil for Rhubarb Planting

When it comes to growing amazing rhubarb, it all starts with preparing the soil. Here are a few things to keep in mind:

Soil Composition

Rhubarb plants require well-draining soil that is rich in organic matter. To achieve this, mix in compost, well-rotted manure, or peat moss to your topsoil. The ideal ratio is one-third organic material to two-thirds topsoil. You can also use Coco-Fiber Potting Medium to improve soil structure.

Soil pH Level

The ideal pH level for rhubarb soil is between 6.0 and 6.8. You can test the pH level using a soil test kit, which can be purchased at your local garden center. If the pH level is too low, you can raise it by adding lime. If the pH level is too high, you can lower it by adding sulfur. Keep in mind that it may take several months for the pH level to adjust, so plan accordingly.

By taking the time to prepare your soil properly, you’ll give your rhubarb plants the best possible chance to thrive.

Planting and Tending to Rhubarb

Growing rhubarb is an easy and rewarding experience for any gardener. With the right techniques, you can produce amazing rhubarb stalks that are perfect for making pies, crumbles, jams, and sauces. In this section, we will discuss the essential steps for planting and tending to your rhubarb plants.

Planting Techniques

To grow rhubarb, you need to start with the right planting techniques. Here are some tips to help you get started:

  • Choose a suitable location: Rhubarb prefers a spot that receives full sun or partial shade. Make sure the soil is well-drained and rich in organic matter.
  • Plant at the right time: Plant your rhubarb crowns in early spring, as soon as the soil is workable. Avoid planting in the summer or fall, as this can lead to poor growth and development.
  • Planting depth: Plant your rhubarb crowns with the top of the crown just below the soil surface. Space the crowns 4 to 6 feet apart, and make sure they are not too close together.
  • Watering: After planting, water your rhubarb well to help it establish roots. Water regularly during dry spells, but avoid overwatering, as this can lead to root rot.

Watering and Fertilizing

Proper watering and fertilizing are essential for healthy rhubarb growth. Here are some tips to help you keep your plants well-fed and hydrated:

  • Watering: Rhubarb needs consistent moisture to grow well. Water deeply once a week, or more often during dry spells. Avoid getting water on the leaves, as this can promote fungal diseases.
  • Fertilizing: Rhubarb is a heavy feeder, so it needs plenty of nutrients to grow well. Apply a balanced fertilizer in early spring, and again in midsummer. You can also add compost or well-rotted manure around the base of the plants to provide additional nutrients.

Pruning and Harvesting

Pruning and harvesting are essential for maintaining healthy rhubarb plants. Here are some tips to help you keep your plants in top condition:

  • Pruning: Remove any flower stalks that appear, as these can reduce the plant’s vigor. Cut back the leaves to the ground in the fall to help prevent disease and insect problems.
  • Harvesting: Wait until the second year after planting to begin harvesting your rhubarb stalks. To harvest, grasp the stalk near the base and pull gently to one side. Cut off the leaves, as they are toxic and should not be eaten. Harvest only a few stalks from each plant at a time to avoid damaging the plant.

By following these planting and tending techniques, you can grow amazing rhubarb that will provide you with delicious and nutritious stalks for years to come.

Dealing with Rhubarb Pests and Diseases

While rhubarb is generally a hardy plant, it can still fall prey to pests and diseases. Here are some common issues and how to deal with them:


  • Aphids: These tiny insects can suck the sap from rhubarb leaves and stems, causing them to wilt and die. You can control aphids by spraying the plant with a strong jet of water or using insecticidal soap.
  • Slugs and snails: These slimy creatures can munch on rhubarb leaves, leaving holes and slime trails behind. You can control them by handpicking them off the plant or using slug pellets.
  • Beetles: Rhubarb can be attacked by various beetles, including the rhubarb curculio and the flea beetle. These pests can cause damage to the leaves and stems. You can control them by using insecticides or covering the plants with netting.


  • Crown rot: This fungal disease can cause the crown of the rhubarb plant to rot, leading to stunted growth and eventual death. You can prevent crown rot by planting rhubarb in well-draining soil and avoiding overwatering.
  • Leaf spot: This fungal disease causes brown spots to appear on the leaves of the rhubarb plant. You can prevent leaf spot by avoiding overhead watering and keeping the area around the plant clean and free of debris.
  • Anthracnose: This fungal disease can cause the stems of the rhubarb plant to rot, leading to wilting and death. You can prevent anthracnose by avoiding overhead watering and keeping the area around the plant clean and free of debris.

By keeping an eye out for these common pests and diseases, you can ensure that your rhubarb plants stay healthy and produce a bountiful harvest.
