Pumpkins are winter squash and need heat to mature properly. Plant seeds in warm (70°) well-drained soil or start indoors one month before last frost. The soil should be well composted and mulched to hold moisture. Vining plants so give them lots of room--18” spacing for lots of small, early fruits; 30” for later, fewer, larger fruits.
