25 Annual Petunia (Petunia Nana Compacta Alderman) Flower Seeds
Petunia (Petunia Nana Compacta Alderman ) - Start these flower seeds for a great, old-fashioned annual that performs all summer long. Petunia Alderman is one of the most colorful annuals for the summer garden. Considered a dwarf, it is sturdy, compact and low-growing providing an abundance of dark violet flowers. It is excellent for mass plantings in the garden, or even in pots or hanging baskets. Petunia flower care includes: deadheading faded flowers for best display and to keep it full of color all season long and fertilizing regularly with a balanced liquid fertilizer.
Sow Petunia seeds indoors 10 - 12 weeks before planting out. The flower seeds are extremely tiny, so press them gently onto the soil surface without covering, and keep the soil wet for the best germination. Placing the trays or containers on top of the refrigerator is beneficial as the heat from the appliance keeps the flower seeds consistently warm. Five or six weeks after sowing the seeds, transplant seedlings into 3 inch pots, and grow on in cooler temperatures with plenty of light. Harden young plants for 10 - 14 days before planting outdoors after last frost date. Plant Petunias in full sun and well-drained soil. When planting outdoors, pinch the young seedlings back to encourage branching.
