- Soil requirements: Petunias prefer well-draining soil with a pH level between 6.0 and 7.0. The soil should be rich in organic matter to support healthy growth.
- Sunlight needs: These seeds require full sun to partial shade. Ideally, they should receive at least 6 hours of direct sunlight daily.
- Watering requirements: Water the seeds regularly to keep the soil consistently moist but not waterlogged. Reduce watering frequency once the plants are established, ensuring the soil remains slightly moist.
- Planting season: The best time to plant Black Purple Rare Phantom Petunia seeds is in the spring after the last frost has passed.
- Depth and spacing: Sow the seeds on the surface of the soil and lightly press them in without covering them, as they need light to germinate. Space the seeds about 6 to 12 inches apart to allow for proper growth.
- Germination time: The seeds typically germinate within 7 to 14 days under optimal conditions.
- Maturity time: Petunias generally reach maturity and start blooming within 10 to 12 weeks after planting.
- Harvesting time: The best time to harvest petunia seeds is in the late summer to early fall when the seed pods have dried and turned brown.
- Harvesting tips: Use a pair of scissors or pruning shears to cut the seed pods from the plant. Allow the pods to dry completely in a cool, dry place before extracting the seeds. Store the seeds in a labeled, airtight container in a cool, dark place for future planting.
