Table of Contents

Rhubarb is a popular garden crop known for its bright red stalks and unique flavor. It's relatively easy to grow and comes back each year, making it a great addition to any home garden.

Getting Started: Rhubarb Plant Care

Choosing the Right Location for Your Rhubarb Plant

When choosing a location for your rhubarb plant, it's important to consider a few things. Firstly, rhubarb plants require full sunshine or at least 6-8 hours of sunlight every day. Secondly, make sure the soil is well-drained and rich in organic matter.

Preparing the Soil for Rhubarb Growth

Before planting your rhubarb, the soil needs to be prepared properly. Start by removing any weeds and rocks, and then work in organic matter such as compost or well-rotted manure. Rhubarb prefers a slightly acidic soil with a pH level around 6.0-6.8.

Planting Your Rhubarb

Rhubarb plants can be started from seeds, but this method can take up to three years to produce a harvest. The recommended method is to plant crowns, which are small sections of mature roots with buds attached. Plant the crowns in early spring, spacing them 3-4 feet apart, and bury them about 2-3 inches deep.

Caring for Your Rhubarb Plant

Watering Your Rhubarb

Watering your rhubarb is important to keep the soil evenly moist but not waterlogged. It's best to water deeply once a week, rather than light watering more frequently. During prolonged dry spells or hot weather, extra watering may be needed.

Feeding Your Rhubarb

Rhubarb is a heavy feeder, meaning it requires a lot of nutrients to grow well. In early spring, apply a balanced fertilizer, such as 10-10-10 or 5-10-5. Spread a layer of compost around the base of the plant each fall to provide organic matter and boost soil fertility.

Weeding Your Rhubarb

Weeding around your rhubarb plant is essential to ensure proper growth and development. Care should be taken not to disturb the rhubarb roots while weeding. Mulching can also help control weeds and retain moisture in the soil.

Protecting Your Rhubarb from Pests and Diseases

Rhubarb plants are generally hardy and don't suffer from many pests or diseases. However, they may be attacked by aphids, slugs or snails. To control these pests, use organic pesticides or employ natural predators like ladybugs or lacewings. Avoid overcrowding the plants to prevent fungal diseases.

Harvesting Rhubarb

When to Harvest Rhubarb

The best time to start harvesting your rhubarb is in its second year when the plant becomes established. Wait until the stalks are at least 10 inches long and then cut them off at the base with a sharp knife.

How to Harvest Rhubarb

To harvest properly, grasp the bottom of each stalk and pull it straight up while holding the leaves back. Only harvest a third of the stalks at a time to maintain plant health.
