Species and varieties: Petunia is a genus of 20 species of flowering plants of South American origin. The most common varieties include Petunia x hybrida (garden petunia), Petunia integrifolia (wild petunia), and Petunia axillaris (white petunia).
Hybrid or heirloom: Petunia seeds are available in both hybrid and heirloom varieties. Hybrid petunias are bred for specific traits such as color, size, and disease resistance, while heirloom petunias are open-pollinated and have been passed down through generations.
Pruning and training: Petunias benefit from regular deadheading to encourage continuous blooming. Pinching back the stems can promote bushier growth. Pruning is generally minimal but can be done to shape the plant and remove any leggy growth.
Fertilization needs: Petunias require regular fertilization to maintain their vibrant blooms. A balanced, water-soluble fertilizer applied every two weeks during the growing season is recommended. Slow-release fertilizers can also be used at the time of planting.
Hardiness zones: Petunias are suitable for USDA hardiness zones 9-11. They can be grown as annuals in cooler climates.
Climate requirements: Petunias thrive in full sun and prefer well-drained soil. They require a warm climate with temperatures between 60-75°F (15-24°C) for optimal growth. They are sensitive to frost and should be planted after the last frost date in cooler regions.
