Know before you buy
Butterkin F1 is a hybrid cross that results in a unique, flat, scalloped shape. It is specifically bred for its exceptionally dark, sweet flesh and a smoother texture that holds up well in both cooking and baking.
Ensure your soil temperature is consistently between 70-75°F before planting. Since this variety requires full sun and moderate water, choose a well-draining spot that receives at least six to eight hours of direct sunlight daily.
The film coating is a protective layer applied to the seed to improve handling and germination success. You should plant these pelleted seeds at a depth of 0.75 to 1.0 inch and cover them lightly, as they require darkness to germinate effectively.
Because these vines can be vigorous, you should space plants 36-48 inches apart within the row. Rows should be spaced 6-8 feet apart to ensure adequate airflow and room for the vines to spread.
Butterkin F1 typically reaches maturity in 105 days. You can expect germination to occur within 6-12 days after sowing, provided the soil conditions remain warm.
Yes, these are reliable hybrid seeds that perform well for both home gardeners and CSA programs. As long as you meet the soil temperature requirements and provide full sun, they are straightforward to grow.
