Petunia Yellow

Petunia (Petunia Grandiflora F1 Single Position Yellow) - Petunia Grandiflora is a traditional summer bedding favorite, and this yellow variety is one you will definitely want to add to your flower garden. Grandiflora yellow flowers easily establish from flower seeds, and they have large, color-drenched blooms that bloom early and heavily all summer long. Yellow Petunias also have a uniform, compact growth habit making them an ideal combination of beautiful blooms and wonderful foliage. They are both reliable and colorful making them a favorite of gardeners! 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. When planting outdoors, pinch the young Petunia seedlings back to encourage branching.
