- Species and varieties: Kentucky green beans, also known as Kentucky Wonder beans, are a popular variety of pole beans. They belong to the species Phaseolus vulgaris and are known for their vigorous growth and high yield. The beans are typically long, tender, and stringless when harvested young.
- Hybrid or heirloom: Kentucky Wonder beans are an heirloom variety, meaning they have been passed down through generations without genetic modification. They are prized for their rich flavor and reliable performance in the garden.
- Pruning and training: Kentucky Wonder beans are pole beans, so they require support such as a trellis, poles, or a fence to climb. Regularly training the vines to climb the support structure will help maximize air circulation and sunlight exposure, leading to healthier plants and higher yields. Pruning is generally not necessary, but removing any damaged or diseased leaves can help maintain plant health.
- Fertilization needs: These beans benefit from a balanced fertilizer applied at planting time. A 10-10-10 (N-P-K) fertilizer is suitable. Once the plants are established, side-dressing with compost or a balanced fertilizer every few weeks can help maintain nutrient levels. Avoid excessive nitrogen, as it can lead to lush foliage at the expense of bean production.
- Hardiness zones: Kentucky Wonder beans can be grown in USDA hardiness zones 3 through 9. They are well-suited to a wide range of climates, making them a versatile choice for many gardeners.
- Climate requirements: These beans thrive in warm weather and require full sun to produce the best yields. They prefer temperatures between 70°F and 85°F (21°C to 29°C) and need well-drained soil with a pH between 6.0 and 6.8. Consistent moisture is important, but the soil should not be waterlogged.
