Growing Info
Harvesting: Harvest frequently to increase yield; squash seem to get monstrous overnight. While edible at almost 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.
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.

So far, I love these squash. I actually have squash growing on my plants. First time in 6 years. I'm keeping my fingers crossed that I will get to harvest them. I've tried all different types of summer squash and so far, these Triumph Summer Squash seeds are the best. I believe I have planted every other seed and they grow, but they never get pollinated, even if I hand pollinate them so I never get any squash.
So far, so good with these Triumph seeds.
