Product Information

Full details

Ideal for home gardeners looking to diversify their vegetable patch with culinary-focused crops, these unique squash varieties serve as a nutritious, low-calorie alternative to traditional potatoes. With both 'Mashed' and 'Baked' cultivars, the primary benefit is the creamy flesh that mimics potato texture in various dishes, though success requires consistent soil moisture and a relatively long growing season to reach maturity.

FAQs

Can I grow these in containers?

Yes, provided you use a large container (at least 20-30 litres) with high-quality potting compost and provide regular feeding and watering.

When is the best time to harvest?

Harvest when the squash stems turn woody and dry, typically in late summer or early autumn before the first frost.

How long can I store these squashes?

If cured properly in a warm, dry place for a week after harvest, these varieties can store for several months in a cool, frost-free location.

Do I need to peel the squash?

While the skin can sometimes be tough depending on the age of the fruit, you can often roast them with the skin on and scoop the flesh out, similar to an acorn squash.

Why use high-potash fertilizer?

High-potash fertilizer (often labeled as tomato feed) encourages fruit development rather than excessive leaf growth, leading to more productive plants.

Troubleshooting

Plants are flowering but not setting fruit

This is often due to poor pollination. Ensure your garden has pollinator-friendly flowers nearby or consider hand-pollinating by transferring pollen from male flowers to female flowers.

Fruits are rotting before harvest

Avoid direct contact between the developing fruit and damp soil. Place a small board or straw under the squashes to elevate them slightly.

Powdery mildew appearing on leaves

Improve air circulation by thinning out overcrowded foliage and ensure you are watering the soil base, not the leaves.

Pros and Cons

Pros

  • Healthy, low-calorie potato substitute
  • Excellent long-term winter storage
  • Produces up to 4 fruits per plant
  • Rich in essential iron and fibre

Cons

  • Requires significant sunlight (minimum 6 hours daily)
  • Demands consistent soil moisture management
  • Requires a warm growing season for optimal harvest

Setup, Compatibility & Care

To begin, start your seeds indoors between April and May using modular trays. If you prefer direct sowing, wait until the soil has thoroughly warmed in May to avoid chilling the germinating seeds. Choose a site that receives at least 6 hours of direct sunlight daily to ensure fruit development. Once transplanted, maintain consistent soil moisture, ensuring the ground does not dry out completely between waterings. To maximize yield, feed your plants every two weeks with a high-potash fertiliser once flowering commences. Always ensure adequate spacing to promote good air circulation, which helps prevent fungal issues like powdery mildew throughout the growing season.
