Rhubarb, with its tart, tangy stalks, is a beloved ingredient in pies, crumbles, and jams. But for many Southern gardeners, the thought of growing this cool-weather crop seems like a pipe dream. While rhubarb thrives in cooler climates, with proper planning and care, you can successfully grow rhubarb in the south. This guide will equip you with the knowledge and strategies to cultivate this delicious plant in your Southern garden.
Understanding Rhubarb’s Needs
Rhubarb, a perennial vegetable, prefers cool, moist conditions. It thrives in USDA hardiness zones 3-8, meaning it can tolerate cold winters. However, the South’s hot summers can pose a challenge. The key to success lies in understanding the plant’s needs and adapting your gardening practices accordingly.
Choosing the Right Variety
Not all rhubarb varieties are created equal. When selecting a variety for your Southern garden, choose one that is known for its heat tolerance. Some recommended varieties include:
- ‘Valentine’: This variety is known for its high yield and good flavor.
- ‘Canada Red’: This variety is resistant to disease and produces bright red stalks.
- ‘Crimson Red’: This variety is known for its excellent flavor and high yield.
Site Selection and Soil Preparation
Rhubarb thrives in a location with full sun to partial shade. Choose a spot that receives at least six hours of sunlight per day. Avoid areas with heavy clay soil, as it can retain too much moisture and lead to root rot.
Prepare the soil by incorporating plenty of organic matter, such as compost or well-rotted manure. This will improve drainage, aeration, and nutrient content. Rhubarb prefers a slightly acidic soil with a pH range of 6.0-6.5. You can adjust the pH by adding lime or sulfur, depending on the current pH of your soil.
Planting Rhubarb Crowns
Rhubarb is typically planted from crowns, which are the roots of the plant. Plant your crowns in the spring, after the last frost. Dig a hole about 12 inches deep and 18 inches wide. Place the crown in the hole, making sure the crown is level with the soil surface. Backfill the hole with soil and water thoroughly.
Watering and Fertilizing
Rhubarb requires consistent moisture, especially during the growing season. Water deeply and regularly, ensuring the soil remains moist but not soggy. During dry periods, you may need to water every other day.
Fertilize your rhubarb plants regularly with a balanced fertilizer, such as 10-10-10. Apply fertilizer in the spring, before new growth emerges, and again in mid-summer. Avoid using fertilizers high in nitrogen, as this can lead to excessive foliage growth at the expense of stalk production.
Protecting Rhubarb from Summer Heat
The South’s intense summer heat can stress rhubarb plants. To mitigate the effects of heat, consider these strategies:
- Mulching: Apply a layer of organic mulch, such as straw or shredded bark, around the base of the plants. Mulch helps retain moisture and moderates soil temperature.
- Shade: If your rhubarb plants are in full sun, provide some shade during the hottest part of the day. You can use a shade cloth or plant taller-growing plants nearby.
- Watering: Water your rhubarb plants deeply and regularly, especially during the hottest months.
- Harvesting: Harvest rhubarb stalks in the spring and early summer. Avoid harvesting after mid-summer, as this will allow the plant to focus its energy on root growth.
Harvesting Rhubarb
Rhubarb is ready to harvest when the stalks are about 12 inches tall. Use a sharp knife to cut the stalks just above the ground. Leave some stalks on the plant to allow it to continue growing.
Winter Care
Rhubarb is a hardy plant that can withstand cold temperatures. However, it’s important to protect the plants from harsh winter conditions. Mulch the plants heavily with straw or shredded bark to insulate the roots and prevent them from freezing.
Rhubarb Pests and Diseases
Rhubarb is relatively pest-free, but it can be susceptible to certain diseases. Common pests include aphids, slugs, and snails. You can control these pests with insecticidal soap or diatomaceous earth. Diseases to watch out for include crown rot, leaf spot, and rust. Good sanitation practices, such as removing infected leaves and avoiding overcrowding, can help prevent these diseases.
Rhubarb’s Culinary Delights
Rhubarb is a versatile ingredient that can be used in a variety of sweet and savory dishes. Its tart flavor pairs well with strawberries, raspberries, and other fruits. Here are some popular ways to use rhubarb:
- Rhubarb Pie: This classic dessert is a must-try for any rhubarb enthusiast.
- Rhubarb Crumble: A simple and delicious dessert that is perfect for a warm summer night.
- Rhubarb Jam: A sweet and tart spread that is perfect for toast, biscuits, or yogurt.
- Rhubarb Sauce: A versatile sauce that can be used to top pancakes, waffles, or ice cream.
- Rhubarb Soup: A unique and refreshing soup that is perfect for a light meal.
