Growing Tips
Cure butternut squash at 25-30 C for 10-14 days after harvest to harden the skin and heal stem wounds before long-term storage.
Butternut squash has better resistance to squash vine borer than C. pepo types (zucchini, pumpkin) due to its harder stems.
Harvest when the skin is uniformly tan and cannot be dented with a fingernail; the stem should be dry and corky.
