Why are my squash flowers falling off?

The plant produces separate male and female flowers, and the male flowers often drop off after shedding pollen.

Can I grow these in a container?

Yes, but you need a very large container, at least 20 gallons, to accommodate the extensive root system.

Quand planter: Spring, Early summer
Hivernage: This plant is an annual and will die with the first frost, so remove and compost the vines once they wither.
En pot: It grows well in large containers of at least 20 gallons, provided you use a sturdy trellis for vining types.

Direct Sowing

Wait until all danger of frost has passed and the soil is warm.
Plant seeds 2 centimeters deep in rich, well draining soil.
Space mounds at least 1 meter apart to allow for spreading vines.

Planting squash with corn and beans creates a classic Three Sisters garden where each plant supports the others.

Bonnes associations

Maïs — Corn provides a natural trellis for vining varieties to climb.
Haricot commun — Beans fix nitrogen in the soil which helps the squash grow.
Capucine — These flowers help deter common garden pests.
