Buttercup squash

SCIENTIFIC NAME:Cucurbita maximaCULTURE:Fertile, well-drained soil with a pH of 6.0–6.8 is best. Plastic mulch and fabric row covers (AG-19 grade) can aide plant establishment and exclude insect pests during the seedling stage. Row covers should be removed when plants begin to flower. Poor fruit development may indicate insufficient pollination.TRANSPLANTING:Sow 2-3 seeds per 2" container or plug flat about 3 weeks prior to transplanting. Thin to 1 plant/container or cell with scissors. Harden plants 4–7 days prior to transplanting. After danger of frost has passed, transplant out according to the spacing recommendations for each variety. Handle seedlings carefully; minimal root disturbance is best.
