Keep soil consistently moist, especially during flowering and fruit development. Water deeply at the base of the plant to prevent fungal diseases. Avoid overhead watering, as this can encourage powdery mildew.

Reduce watering slightly once fruits begin to mature to improve flavor.

Pruning is generally not required for acorn squash. If vines become excessively long or crowded, you can trim them back to improve air circulation and manage space.

Focus on removing any damaged or diseased leaves to maintain plant health and prevent disease spread.

Start seeds indoors 3-4 weeks before the last expected frost. Sow seeds about 2. 5 cm deep in individual pots.

Acorn squash can also be direct-sown outdoors after all danger of frost has passed and soil temperatures have warmed to at least 21°C.

Repotting is not applicable to acorn squash as it is typically grown directly in the ground or in large, permanent containers. If starting seeds indoors, transplant seedlings into larger pots if they outgrow their initial containers before outdoor planting.
