Strawberry rhubarb is a classic combination that has been a staple in many gardens and kitchens for centuries. The sweetness of strawberries pairs perfectly with the tartness of rhubarb, making it a match made in heaven. If you’re interested in growing your own strawberry rhubarb, you’ve come to the right place. In this article, we’ll take you through the process of cultivating this delicious duo, from preparing the soil to harvesting your crop.
Understanding Strawberry Rhubarb
Before we dive into the nitty-gritty of growing strawberry rhubarb, it’s essential to understand the characteristics of each plant.
Strawberries
Strawberries are a type of fruit that belongs to the rose family. They are perennials, meaning they come back year after year, and are relatively easy to grow. Strawberries are also self-pollinating, which means they don’t require another plant to produce fruit. There are three main types of strawberries:
- June-bearing strawberries: These strawberries produce one large crop in the spring.
- Ever-bearing strawberries: These strawberries produce multiple smaller crops throughout the growing season.
- Day-neutral strawberries: These strawberries produce continuously throughout the growing season, regardless of the length of daylight.
Rhubarb
Rhubarb is a type of vegetable that belongs to the buckwheat family. It’s also a perennial and is often grown for its tart stalks, which are used in pies and other desserts. Rhubarb is typically grown from crowns, which are sections of the plant’s root system. There are two main types of rhubarb:
- Garden rhubarb: This is the most common type of rhubarb and is grown for its edible stalks.
- Ornamental rhubarb: This type of rhubarb is grown for its decorative leaves and stalks.
Preparing the Soil
Before you can start growing strawberry rhubarb, you need to prepare the soil. Both strawberries and rhubarb prefer well-draining, fertile soil that is rich in organic matter.
Testing Your Soil
The first step in preparing your soil is to test its pH level. Strawberries prefer a slightly acidic soil with a pH between 5.5 and 6.5, while rhubarb prefers a slightly alkaline soil with a pH between 6.0 and 6.5. You can purchase a soil testing kit or send a sample to a lab for analysis.
Adding Organic Matter
Once you’ve determined your soil’s pH level, you can start adding organic matter to improve its fertility and drainage. Some good options include:
- Compost: This is a rich source of nutrients that can help improve soil structure and fertility.

- Cut the stalks at the base of the plant, using a sharp knife or pruning shears
- Avoid harvesting too much, as this can weaken the plant
By following these tips and guidelines, you should be able to grow delicious strawberry rhubarb in your own garden. Happy growing!
What are the ideal growing conditions for strawberry rhubarb?
Strawberry rhubarb is a cool-season crop that thrives in temperate climates with moderate temperatures and adequate moisture. It prefers full sun to partial shade and well-draining soil rich in organic matter. The ideal soil pH for strawberry rhubarb is between 6.0 and 6.5. In terms of temperature, strawberry rhubarb grows best in daytime temperatures between 60°F and 70°F (15°C and 21°C) and nighttime temperatures around 50°F (10°C).
It’s essential to note that strawberry rhubarb is sensitive to extreme temperatures, drought, and waterlogged soil. Therefore, it’s crucial to provide consistent moisture, especially during the first year after planting. Mulching around the plants can help retain moisture, suppress weeds, and regulate soil temperature. Additionally, strawberry rhubarb is a hardy perennial that can tolerate light frosts, but prolonged exposure to extreme cold or heat can damage the plants.
How do I prepare the soil for planting strawberry rhubarb?
Preparing the soil is a critical step in growing strawberry rhubarb. Start by testing your soil pH and adjusting it if necessary. Add organic matter such as compost or well-rotted manure to improve soil fertility and structure. Remove any debris, rocks, and weeds from the planting area. Till the soil to a depth of 8-10 inches (20-25 cm) to loosen and aerate it.
For strawberry rhubarb, it’s recommended to create a raised bed with a mix of topsoil, compost, and perlite or vermiculite. This will help improve drainage, aeration, and soil temperature. You can also add a balanced fertilizer according to the manufacturer’s instructions. Once the soil is prepared, create a planting hole that is twice as wide and just as deep as the root ball of the strawberry rhubarb plant.
