Cultivation
Acorn squash is very easily grown: seeds are started after the danger of frost is past and the soil is warm or started for transplant 3 to 4 weeks before the predicted last frost date in the area. In one method, seeds directly sown are placed 25 mm (1 inch) deep, 5 to 6 to a hill. Grow hills are separated by 2 m (6 feet) in all directions.
About 85 days after germination, acorn squash are ready to be harvested.
Storage
Acorn squash keep well in a temperature-controlled environment, such as a root cellar, maintaining their quality well for at least 3.5 months with a simple cleaning pretreatment known as Hot Water Rinsing and Brushing or HWRB.
Curing
Curing takes seven to ten days in a sheltered area outside or a warm dry place (like a storage space) protected from frost. The curing process helps the fruit keep longer before spoiling.
Characteristics
As with other squash varieties, the acorn squash vine makes yellow trumpet flowers that are edible. Tops about three inches from the end are also edible and they are one of the most common vegetables in the Philippines (as
greens).
