|'Boston Marrow', also known as 'Autumnal Marrow', is an heirloom variety pumpkin which is excellent for areas where summer is short and relatively cool. 14-16 feet long vines produces ripe fruits by first frost, although it is generally considered a 100 day squash. Excellent for planting under corn. The squashes are thin-skinned and easily damaged, weighing 8-9 pounds, and either bright orange or bluish-pink. Small pumpkins are grown for cooking and eating, while the larger sizes are for Jack-o'-lanterns and exhibition. Most Cooperative extension services will be able to tell you which varieties are best for your area. Plant seed 2 or 3 weeks after the last average frost date. They will tolerate partial sun and require high organic matter and well drained soil. Go easy on the fertilizer as you will end up with all vine. Keep pumpkins well watered.
They are usually ready for harvest 95 to 120 days after planting. Pumpkins can stay on the vine for a long time, but harvest them before the first hard frost as they will get mushy. Pumpkins require too much space to be grown in containers.
