My garden is always crazy with wild squash. I don’t ever remember planting it. I almost suspect it came from the free compost in new Berlin. I always have some left over at the end of the season and compost it. This could be a source of many additional seeds for next year. This stuff appears cross pollinated between spaghetti and acorn, and every sharp color in between. Some even looks like watermelon. Any thoughts to where it came from? Not sure about the compost. It grows so well in my cruddy West Allis clay. I actually had to quarantine it to its own separate area because it TAKES over! Any suggestions? Hints? It’s wonderful to eat when it’s young. The shell, seeds and all. When it’s young, all is wonderful and tender. I am the squash king.
The compost is your most likely source of your mystery plant.
If this is a delicious variety, you can save seeds. The seeds still may then not grow true to your original plant.
