Plant Care & Growing Tips

Growing beautiful Grandiflora Petunias from petunia seeds is a rewarding experience. For best results, start seeds indoors 8-10 weeks before the last expected frost. Sow seeds on the surface of a well-draining seed starting mix, as they require light to germinate. Do not cover them. Keep the soil consistently moist but not waterlogged. Maintain a temperature of 70-75°F (21-24°C) for optimal germination, which usually occurs within 7-14 days. Once seedlings emerge, provide plenty of bright light, either from a south-facing window or under grow lights, to prevent them from becoming leggy.

After the danger of frost has passed, gradually harden off your young petunia plants before transplanting them outdoors. Choose a location that receives full sun, ideally 6-8 hours of direct sunlight per day, as this promotes the most abundant flowering. Petunias can tolerate partial sun, but flowering may be reduced. Plant them in rich, well-draining soil. If planting in containers, use a high-quality potting mix. Space plants 8-12 inches apart to allow for good air circulation. Water regularly, especially during dry spells, ensuring the top inch of soil dries out slightly between waterings. Avoid overhead watering to prevent fungal diseases. Fertilize every 2-4 weeks with a balanced liquid fertilizer to encourage continuous blooming. Deadhead spent flowers regularly to promote new growth and more rainbow petunia flowers. These mixed petunia seeds will reward you with a season full of color with proper care.
