Growing Info
Harvesting: Harvest frequently to increase yield; squash seem to get monstrous overnight. While edible at any size, seeds are less developed in young fruit, therefore more tender. Using a knife or clippers, cut squash off including some of the stem. By including stem, the fruit is sealed and less likely to mold or dry out. Harvesting Blossoms: Look for male, non-fruit producing flowers that have long stems and harvest just before use (female flowers have a swollen mini-squash at the base of the flower and shorter stems)
Special Care: Floating row covers can help protect from squash vine borer and cucumber beetles. Remove covers when plants begin flowering. Another method to exclude vine borers is to cover the base of the stems near the ground with mulch, foil, or fabric material, as the base of the stem is where insect eggs are laid. Squash plants are susceptible to fungal disease, so make sure plants have ample space for air circulation. Sowing pollinator-attracting plants near squash can assist in proper pollination, resulting in a bigger harvest and well-shaped fruit.

These have done wonderfully in my garden this season!!!
Pros:
Easy to Grow: I just threw them in the ground in late May and walked away. Couldn't be simpler.
Excellent Germination: 100% of the seeds in my packet sprouted.
Incredibly Resilient: This is the key takeaway. They are not resistant to squash vine borers, and they did get bored through. However, unlike my other squash plants that died, these have powered through the damage and are still going strong.
Cons:
Not immune to pests, so you still need to be watchful. (I was picking off eggs and cutting off parts affected. They are not resistant, but are resilient, as they are the only ones that have survived the SVB moths.)
Overall, I highly recommend this variety, especially for gardeners who have lost plants to vine borers in the past. I'm very happy with the results!
