Butternut squash, known as a winter squash, is commonly found on dinner tables in fall and winter months. Harvest butternut squash in late September or October, depending upon your climate. Wherever you live, harvest the squash before the first hard frost. While a light frost won't damage the squash, a hard freeze may cause it to rot.
Gently press against the rind. If the rind is hard, and the squash is a deep, golden color, it is ready to harvest.
Lift up on the squash so that the vine it is attached to also raises up.
Cut the squash from the vine, leaving 3 to 4 inches of vine stem. Repeat steps 1 through 3 until you have harvested all of the ripe butternut squash.
Gently remove any dirt from the outside of the squash, being careful to not puncture the rind.
Gently twist on the vine stem that is still connected to the squash. If the vine is dry and ready to be removed, it will easily pop off. Removing the stem before storage will prevent it from damaging or poking into the rind of the other butternut squashes.
