FAQs

When is the best time to sow these seeds?

The ideal sowing period is from April to May for the best harvest results.

How much space does each plant need?

Each plant requires a spread of up to 200cm, so ensure you have sufficient space in your garden beds.

Can I grow these in containers?

While technically possible, the 200cm spread makes large-scale ground planting or very large troughs more suitable than standard pots.

How deep should I sow the seeds?

Seeds should be sown 1cm deep in high-quality, free-draining compost.

How heavy are the fruits?

On average, each fruit will weigh approximately 1.5kg when fully mature.

Are these squash safe to eat raw?

Yes, the flesh is versatile and can be enjoyed raw, baked, or steamed.

Troubleshooting

Seeds fail to germinate

Verify that the ambient temperature remains consistently between 20-25°C and that the compost is kept moist but not waterlogged.

Plants show signs of frost damage

If frost is predicted early in the season, cover young seedlings with garden fleece or cloches to insulate against cold snaps.

Low fruit production

Ensure the plants are in a position receiving full sun and that they have adequate access to pollinators; if insects are absent, consider manual pollination.
