When Is The Best Time To Harvest Hubbard Squash

The hubbard fruit should be ready for harvest in about 50 to 55 days after the fruit sets. However, note that the exterior that tends to be hard doesn’t indicate the ripeness of hubbard squash.

Additionally, the best way to know when hubbard squash is ready for harvest is when the maturation day has passed. This maturation date is usually around 100 to 120 days. Also, you can wait until the vine starts to die off to ascertain the hubbard squash is ready for harvest.

If this part of the stem has begun to dry and looks cork-like, then it’s fine to harvest. It means the vine isn’t giving the fruit nourishment anymore.

However, if the stem remains moist and viable, refrain from harvesting it. The fruit is still obtaining nourishment and hasn’t attained its full flavor potential, sweetness, and seed viability.

Furthermore, harvesting should also be done right before any heavy frost. This is because this type of squash is a tropical plant and heavy frost can damage the fruit.
