Growing Buttercup Squash
Buttercup squash grows on vines or in bushes. Each vine will need 6ft of row spacing for bush or short vine varieties. If it is a long vine variety, it will need 12 feet.
The traditional way of growing squash plants is to plant them on the tops of a mound and allow a tall plant like corn or sunflowers to support the growth of the vines. You can also plant them at the end of a row, and train the vines to grow away from other plants.
If you want to add some height to your garden, you can grow this squash on a trellis or tepee, by tying up the vines as they grow. If the weight of the squash gets too heavy for a trellised vine, you can use parachute cord to create a net to hold it's weight until rip.
These plants do well in loose, well-drained soil. That is side composted rather than being fertilized because over-fertilizing will cause the plant to leaf out, but not grow any fruit. The ideal pH range for squash is 5.8-7.0pH. Because squash is hardy, as long as you have well-draining soil, your plants should thrive.
Be sure to give your buttercup squash plant plenty of room in your garden; it will spread out and take up space you give it, six to 12 feet depending on vine or bush size.
