Choosing the Right Knee-High Sweet Pea Variety

The first step to growing knee-high sweet peas is selecting the perfect variety. Look for cultivars specifically labeled as “dwarf,” “compact,” or “bush” sweet peas. These varieties typically reach heights of 12 to 18 inches, making them ideal for smaller spaces. Some popular knee-high sweet pea varieties include:

• ‘Cupid Mixed’: This mix offers a vibrant blend of colors and delightful fragrance.
• ‘Sweet Pea ‘Little Sweetheart’ Mix’: This mix features a range of pastel shades in a compact, bushy habit.
• ‘Sweet Pea ‘Royal Wedding’: This variety boasts large, fragrant blooms in a beautiful white and pink combination.

Sowing Sweet Pea Seeds: Timing is Key

Sweet peas are cool-season plants, meaning they prefer cooler temperatures and thrive in spring and fall. To get a head start, sow seeds indoors 6-8 weeks before the last frost date in your area.

• Indoor Sowing: Fill seed trays or pots with a seed-starting mix. Sow seeds 1/2 inch deep and space them 1-2 inches apart. Keep the soil moist and maintain a temperature of 65-70°F. Once seedlings emerge, provide them with plenty of light.
• Direct Sowing: You can also direct sow sweet pea seeds outdoors after the last frost date. Choose a sunny spot with well-drained soil. Sow seeds 1 inch deep and 2-3 inches apart.

Providing the Right Growing Environment

Knee-high sweet peas need a sunny location with at least 6 hours of direct sunlight per day. They also prefer well-drained soil that’s rich in organic matter. Here’s how to create the ideal environment for your sweet peas:

• Soil Preparation: Before planting, amend the soil with compost or aged manure to improve drainage and fertility.
• Watering: Keep the soil consistently moist, especially during hot weather. Water deeply but avoid overwatering, as this can lead to root rot.
• Fertilizing: Feed your sweet peas with a balanced liquid fertilizer every 2-3 weeks.

Supporting Your Knee-High Sweet Peas

While knee-high sweet peas are naturally compact, they still benefit from some support. This helps them maintain their shape and prevents stems from becoming tangled.

• Trellises: Use small trellises or stakes to support the plants. You can use decorative trellises or create your own using bamboo stakes and twine.
• Cages: Wire cages or tomato cages can also provide support for knee-high sweet peas.

Pinch Back for Abundance

Pinching back the top growing tips of your sweet pea plants encourages bushier growth and more blooms. This technique also helps to prevent the plants from becoming leggy. Pinch back the tips when the plants are about 6 inches tall.

Enjoying Your Blooming Knee-High Sweet Peas

With proper care, your knee-high sweet peas will reward you with a beautiful display of fragrant blooms. Here are some tips for enjoying your sweet peas:

• Deadheading: Regularly remove spent blooms to encourage more flowers. This process, known as deadheading, also helps to prevent the plant from setting seeds and diverting energy from blooming.
• Cutting Flowers: Enjoy the beauty of your sweet peas indoors by cutting stems for bouquets. Cut stems early in the morning, when the flowers are at their freshest.
• Preserving Flowers: Preserve the beauty of your sweet peas by drying them. Hang stems upside down in a cool, dry, and dark place.

Growing knee-high sweet peas is a rewarding experience. It allows you to enjoy their captivating fragrance and vibrant colors in a convenient and manageable size.
