My trial at growing butternut squash was a bust; I pulled all the plants today. The two I planted in pots and kept on my deck stayed small and anemic-looking all summer no matter the fertilizer, fresh soil or nails stuck into the dirt (for iron). The two I planted near my potatoes and peas by the retaining wall grew larger and were a darker green, but really didn’t do anything at until mid-July. Even when they started blooming at the end of July, they never set any fruit.
The mystery squash that popped up with the zucchini in my raised bed grew much better; it vined out into the yard and had some flowers and fruit. Mystery solved — it was a buttercup. However, the fruit was no larger that a shooter marble, so I decided to pull it up so that it stopped stealing moisture and nutrients from the zucchini plants.
I’ll try something new next year, maybe more potatoes or Jerusalem artichokes.
