Rhubarb, often mistakenly referred to as a fruit due to its common pairing with strawberries in pies, is actually a vegetable that thrives in cooler climates. It’s a perennial plant with edible stalks that can add a tart flavor to a variety of dishes, from desserts to savory meals. For gardeners in New York, the question of whether rhubarb can be grown in the state’s climate is of particular interest. New York’s varied climate, ranging from the cold winters of the Adirondacks to the milder conditions of Long Island, presents both opportunities and challenges for rhubarb cultivation. In this article, we will delve into the specifics of growing rhubarb in New York, covering the ideal conditions, planting and care tips, and potential challenges.
Understanding Rhubarb Basics
Before attempting to grow rhubarb, it’s essential to understand its basic requirements. Rhubarb is a hardy perennial, meaning it comes back year after year if properly cared for. It prefers full sun to partial shade and well-drained soil that is rich in organic matter. The crown of the rhubarb plant, from which the edible stalks grow, needs a period of cold winter weather to induce dormancy, which is crucial for the plant’s health and productivity. New York’s cold winters make it an ideal location for growing rhubarb, as the plant can naturally go through the necessary dormancy period.
Rhubarb Varieties for New York
Choosing the right variety of rhubarb is crucial for success in New York’s climate. Some popular varieties include ‘Canada Red’, ‘Valentine’, and ‘Crimson Wine’. These varieties are known for their disease resistance, flavor, and hardiness, making them well-suited for New York’s conditions. When selecting a variety, consider factors such as stalk color, flavor, and maturity date to ensure you find a type that suits your preferences and the specific climate of your region within New York.
Planting Rhubarb
Planting rhubarb in New York should be done in early spring, as soon as the soil can be worked, or in fall, about 6 to 8 weeks before the first frost. This timing allows the crowns to establish themselves before the winter or summer extremes. Rhubarb is typically planted as crowns, which are segments of root that have at least one “eye” or bud from which the new stalks will grow.
When planting, ensure the soil is well-drained and amended with compost or manure to improve its fertility and structure. The crown should be placed in the ground with the buds facing upwards, and the soil level should be the same as it was on the crown when it was purchased. Water well after planting and keep the soil consistently moist during the first growing season.
Caring for Rhubarb Plants
Proper care is essential for the health and productivity of rhubarb plants. This includes mulching, watering, fertilizing, and dividing the plants as needed. Mulching around the plants helps retain moisture, suppress weeds, and regulate soil temperature. Watering should be consistent, especially during the first year after planting, but be cautious not to overwater, which can lead to root rot.
Fertilizing rhubarb plants annually with a balanced fertilizer will promote healthy growth and productivity. It’s also beneficial to add a layer of compost around the plants in the spring to provide nutrients as they start to grow. Rhubarb plants typically need to be divided every 5 to 10 years, as the crowns can become congested, leading to decreased productivity. Division should be done in early spring or fall, using a sharp tool to carefully separate the crowns, ensuring each section has at least one bud.
Pest and Disease Management
Like all garden plants, rhubarb can be susceptible to pests and diseases. Common issues include rhubarb curculio, slugs, and powdery mildew. Rhubarb curculio, a type of beetle, can cause significant damage to the stalks. Slugs can chew holes in the leaves and stalks, especially at night. Powdery mildew can appear as a white powder on the leaves, especially during humid weather. Managing these issues often involves a combination of good garden hygiene, the use of physical barriers (like copper tape to deter slugs), and, in severe cases, the application of appropriate pesticides or fungicides.
Hibernation and Forcing
Rhubarb plants typically go dormant during the winter, and this period of hibernation is crucial for their health and productivity. However, gardeners can force rhubarb to produce stalks earlier by covering the crowns with a layer of straw or a rhubarb forcer in late winter. This method warms the soil and simulates the longer days of spring, prompting the rhubarb to produce stalks several weeks before they would naturally appear. Forcing should be done cautiously, as it can weaken the plant if done too frequently or too early.
Harvesting Rhubarb
One of the most exciting parts of growing rhubarb is the harvest. Rhubarb is typically ready to harvest in late spring, about 8 to 10 weeks after the plants emerge. The stalks should be picked when they are between 10 to 15 inches long and still crisp. Harvesting is usually done by grasping the stalk near the base and twisting it away from the crown. Be sure not to pull on the stalks, as this can damage the crown. It’s also important to leave at least 2 to 3 stalks on each plant to ensure its continued health and productivity.
Cooking with Rhubarb
Rhubarb’s tart flavor makes it a versatile ingredient in a variety of dishes. It’s most famously paired with strawberries in pies and jams, but it can also be used in savory dishes, added to salads, or made into sauces and chutneys. Rhubarb can be cooked with sugar to balance its tartness, or it can be used in recipes where its acidity is an asset, such as in marinades or braising liquids.
Rhubarb Recipes
For those looking to explore the culinary possibilities of rhubarb, here are a few ideas:
- Rhubarb and Strawberry Pie: A classic dessert that combines the tartness of rhubarb with the sweetness of strawberries.
- Rhubarb Chutney: A spicy and tangy condiment made by cooking rhubarb with onions, ginger, and sometimes apples or pears, perfect for accompanying grilled meats or cheeses.

With proper care and attention, container-grown rhubarb can thrive and produce a delicious harvest, even in small spaces.
How do I harvest rhubarb in New York?
Harvesting rhubarb in New York is a straightforward process that requires some basic knowledge. Rhubarb is typically ready to harvest in late spring, about 6-8 weeks after the plants emerge from dormancy. To harvest, grasp the rhubarb stalk at the base, just above the soil line, and gently twist it away from the plant. This helps to avoid damaging the crown or roots. Harvest only the tart, edible stalks, leaving the leaves intact, as they are toxic and should not be eaten.
When harvesting rhubarb, gardeners should only take a portion of the stalks, leaving enough to allow the plant to continue growing and producing. A general rule of thumb is to harvest no more than one-third to one-half of the stalks at any given time. This helps to maintain the plant’s vigor and promotes healthy growth. After harvesting, gardeners can use their fresh rhubarb in a variety of recipes, from pies and jams to sauces and salads. With proper harvesting and care, rhubarb plants can continue to produce delicious stalks for many years, making them a valuable and rewarding addition to any New York garden.
