Choosing the Right Variety
Climate Considerations
When it comes to growing rhubarb in Georgia, it’s important to consider the climate. Rhubarb thrives in cooler temperatures and does best in USDA hardiness zones 3-8. While Georgia’s climate tends to be warmer overall, there are some areas in the northern part of the state that may have cooler temperatures suitable for growing rhubarb. It’s also worth noting that rhubarb prefers a cold dormant period during the winter months, so finding a variety that can withstand the milder winters of Georgia is key.
Recommended Varieties
While there are many rhubarb varieties to choose from, some are better suited for Georgia’s climate than others. Here are a few varieties that are recommended for growing rhubarb in Georgia:
-
Victoria: This is one of the most common varieties of rhubarb and is known for its excellent flavor. It has thick, red stalks and is relatively easy to grow.
-
Canada Red: As the name suggests, this variety has vibrant red stalks that are not only visually appealing but also have a pleasant tartness. It is a popular choice for baking and making preserves.
-
Raspberry Red: This variety is prized for its unique red and green marbled stalks. It has a slightly sweeter flavor compared to other varieties, making it great for both sweet and savory dishes.
It’s important to choose a variety that suits your taste preferences and climate conditions. Make sure to do your research and select a variety that is suitable for growing in Georgia.
Preparing the Soil
Testing the Soil
Before planting rhubarb, it’s crucial to test the soil to determine its pH level and nutrient content. Rhubarb prefers slightly acidic soil with a pH range of 5.0-6.5. A soil test will help you understand if any amendments are needed to optimize the growing conditions for your rhubarb plants.
Amending the Soil
If the soil test reveals that the pH level is outside the preferred range, you can make adjustments by adding organic matter, such as compost or well-rotted manure, to the soil. This will help improve the soil structure and nutrient content.
Additionally, rhubarb plants benefit from a well-draining soil. You can amend heavy clay soils by incorporating coarse sand or peat moss to improve drainage. On the other hand, if the soil is too sandy and drains too quickly, you can add organic matter to increase moisture retention.
Improving Drainage
Ensuring proper drainage is crucial for the health and success of your rhubarb plants. If your soil tends to be heavy and retains water, you can create raised beds or planting mounds to improve drainage. This will prevent waterlogging and help prevent diseases that thrive in wet conditions.
Planting Rhubarb
Best Time to Plant
The best time to plant rhubarb in Georgia is in late winter or early spring, ideally between February and March. This allows the plants to establish themselves before the hot summer temperatures arrive. Planting rhubarb too late in the season may result in weak growth and reduced yields.
Choosing a Planting Location
When selecting a planting location for your rhubarb, choose a site that receives at least six hours of sunlight daily. Rhubarb plants thrive in full sun but can tolerate some shade. Avoid planting them in areas that are prone to strong winds, as this can damage the leaves and stalks.
Preparing the Planting Site
Prepare the planting site by removing any weeds or grass and loosening the soil with a garden fork or tiller. Remove any rocks or debris that could hinder the growth of your plants. It’s also a good idea to incorporate organic matter, such as compost or aged manure, into the soil to provide additional nutrients.
Planting Rhubarb Crowns
Rhubarb is typically grown from crowns, which are the divided roots of mature plants. Dig a hole deep enough to accommodate the crown and its roots, ensuring that the bud is just above the soil surface. Space the crowns about 3-4 feet apart to give the plants room to grow. Gently firm the soil around the crown and water thoroughly.
Watering and Mulching
Watering Needs of Rhubarb
Rhubarb requires regular watering, especially during dry periods. While it is important to keep the soil consistently moist, it’s crucial to avoid overwatering, as this can lead to root rot. A good rule of thumb is to water deeply once a week, providing about 1-2 inches of water. Adjust the frequency based on weather conditions and the moisture levels of the soil.
Mulching to Retain Moisture
Mulching around the base of your rhubarb plants can help conserve moisture, suppress weed growth, and maintain a more consistent soil temperature. Apply a layer of organic mulch, such as straw or wood chips, around the plants, ensuring that it does not come into direct contact with the stalks. This will help retain moisture in the soil and reduce the need for frequent watering.
Fertilizing Rhubarb
Understanding Nutritional Needs
Rhubarb is a heavy feeder and requires an adequate supply of nutrients to support its growth and development. To ensure a healthy crop, it’s important to understand its nutritional needs. Rhubarb thrives in nutrient-rich soil with adequate levels of nitrogen, phosphorus, and potassium. It also benefits from supplemental calcium, which helps prevent nutrient deficiencies and enhances stalk quality.
Best Fertilizers for Rhubarb
To meet the nutritional needs of your rhubarb plants, consider using organic fertilizers, such as compost or well-rotted manure. These will provide a slow release of nutrients over time. You can also incorporate a balanced granular fertilizer or a slow-release fertilizer specifically formulated for rhubarb into the soil during planting and annually in early spring.
When and How to Fertilize
Apply fertilizers in early spring, just as new growth begins to emerge. Spread the recommended amount evenly around the base of the plants, taking care not to let it come into direct contact with the stalks. Water thoroughly after fertilizing to help the nutrients reach the root zone. Avoid over-fertilizing, as this can lead to excessive leafy growth at the expense of stalk production.
Controlling Weeds
Mulch to Suppress Weeds
Mulching not only helps retain moisture but also suppresses weed growth around your rhubarb plants. Apply a layer of organic mulch, such as straw or wood chips, to the soil surface, being careful to keep it away from the stalks. This will smother weed seeds and prevent them from germinating, reducing the need for frequent weeding.
Hand-Pulling Weeds
Regular inspection and hand-pulling of weeds are essential to keep your rhubarb bed weed-free. Be thorough and remove weeds as soon as you spot them to prevent them from competing with your plants for nutrients and moisture. Pull the weeds gently, taking care not to disrupt the shallow root system of the rhubarb plants.
Using Herbicides
If manual weed control becomes overwhelming, you can use herbicides labeled for use in vegetable gardens. It’s important to read and follow the instructions carefully, as some herbicides may have restrictions on use near edible crops. Always consider organic, non-toxic alternatives first and prioritize the health of your plants and the environment.
Pruning and Thinning
Pruning Dead Leaves and Stalks
Regular pruning is important to keep your rhubarb plants healthy and productive. Remove any dead or damaged leaves and stalks to prevent the spread of diseases and improve air circulation around the plants. You can cut the stalks at ground level or gently twist them off to avoid damaging the crown.
Thinning Rhubarb Plants
At least every three to four years, it is recommended to thin out your rhubarb plants. Over time, rhubarb plants can become overcrowded, which can lead to reduced yields and poor plant health. Dig up the young plants that have developed around the original crown and replant them in a different location or give them away to fellow gardeners.
Pests and Diseases
Common Pests
While rhubarb is generally a low-maintenance plant, it can still be susceptible to some pests. Common pests that may affect your rhubarb include aphids, slugs, snails, and beetles. Regular inspection of your plants and prompt action can help minimize any potential damage.
Common Diseases
Rhubarb can also be susceptible to various diseases, including crown rot, leaf spot, and powdery mildew. Adequate spacing, good airflow, and proper sanitation practices can help prevent the spread of diseases in your garden. It’s also important to avoid overhead irrigation, as wet foliage can contribute to disease development.
Preventive Measures
To prevent pest and disease problems, practice good garden hygiene by removing any fallen leaves or plant debris. This will help reduce the risk of diseases and discourage pests from taking up residence in your garden. Additionally, consider using organic pest control methods, such as insecticidal soaps or neem oil, to manage pests naturally.
Harvesting Rhubarb
First Harvest
Rhubarb plants should not be harvested during their first year of growth, as this allows them to become well-established. In the second year, you can start harvesting a few stalks, but only take a few at a time to avoid stressing the plants. Gently pull or cut the stalks at the base, close to the crown, and remove any leaves.
Subsequent Harvests
Once your rhubarb plants are fully established, you can harvest stalks throughout the growing season. It’s important to remember to leave at least a third of the stalks intact to allow the plants to continue producing energy through photosynthesis. Regular harvests will promote new growth and help ensure a bountiful harvest year after year.
Harvesting Techniques
When harvesting rhubarb, always pull or cut the stalks at the base where they meet the crown. Pulling the stalks with a slight twisting motion can help prevent damage to the crown and future growth. It’s essential to remove any leaves from the stalks, as they are toxic and should never be consumed.
Storing and Preserving Rhubarb
Storing Fresh Rhubarb
To store fresh rhubarb, trim off any leaves and wrap the stalks loosely in a damp paper towel. Place them in a plastic bag and store in the refrigerator’s vegetable crisper drawer. Fresh rhubarb can typically be stored for up to two weeks, but it’s best to use it as soon as possible for the best flavor and texture.
Freezing Rhubarb
If you have a surplus of rhubarb, freezing is an excellent way to preserve it for future use. Wash, trim, and cut the stalks into desired pieces. Blanch the pieces in boiling water for a couple of minutes, then plunge them into ice water to stop the cooking process. Drain them well, pack into airtight freezer bags or containers, and store in the freezer for up to a year.
Preserving Rhubarb
Rhubarb also lends itself well to various preserving methods, such as making jams, jellies, sauces, and pies. Experiment with different recipes and techniques to enjoy the unique flavor of rhubarb long after the growing season has ended. Canning and pickling are also popular options for preserving rhubarb.
