FAQs

When is the best time to sow 'Tiger Cross' marrow seeds?

You can sow seeds indoors from April to May for transplanting later, or direct sow outdoors from late May to June, once the risk of frost has passed.

What kind of soil is best for growing these marrows?

They thrive in rich, fertile, well-drained soil. It's recommended to prepare the soil in early spring by adding plenty of well-rotted farmyard manure.

How much space do these plants need?

Plants should be spaced 90cm (36 inches) apart to allow for their full spread.

Are 'Tiger Cross' marrows susceptible to pests?

While resistant to mosaic virus, young plants can be vulnerable to birds and insects. Protective netting or fleece is recommended initially. Ensure good aphid control.

Can I store the marrows after harvesting?

Yes, 'Tiger Cross' marrows can be stored in cool conditions for later consumption, in addition to being enjoyed fresh.

What does F1 Hybrid mean?

F1 Hybrid refers to the first generation offspring of a cross between two distinct parent varieties. F1 hybrids often exhibit enhanced vigor, uniformity, and yield.

What are the mature dimensions of a 'Tiger Cross' marrow plant?

When fully established, the plants can reach a height of up to 45cm (17.7 inches) and spread up to 90cm (35.4 inches).

Troubleshooting

Seeds fail to germinate indoors

Ensure consistent temperature (20-25°C) and adequate moisture. Check that the compost is fresh and free-draining. Do not exclude light.

Young plants are damaged by birds or insects

Use protective netting or fleece immediately after planting outdoors until the plants are more established.

Poor fruit development

Ensure plants are in full sun, have fertile soil, and receive consistent watering. Hand-pollination may be necessary if natural pollinators are scarce.

Plants show signs of mosaic virus

While resistant, severe outbreaks can still occur. Remove affected plants immediately to prevent spread. Ensure good aphid control, as they can transmit the virus.

Marows are rotting at the base

Ensure good drainage in the soil and avoid overwatering. Lifting the developing fruit slightly off the soil with a piece of wood or tile can help.

Setup, Compatibility & Care

Sowing Indoors:

  1. Start seeds indoors from April to May.
  2. Sow seeds 2.5cm (1 inch) deep in individual 7.5cm (3 inch) pots using free-draining seed compost.
  3. Place pots in a propagator or seal in a plastic bag at 20-25°C (68-77°F) for germination, which typically takes 5-7 days. Do not exclude light.
  4. Once germinated, grow plants in cooler conditions until all risk of frost has passed and they are large enough to transplant.
  5. Gradually acclimatize plants to outdoor conditions over 7-10 days.

Direct Sowing Outdoors:

  1. Prepare the soil in early spring by incorporating well-rotted farmyard manure.
  2. Direct sow outdoors from late May to June.
  3. Sow seeds 2.5cm (1 inch) deep, 90cm (36 inches) apart. Sow two seeds per hole.
  4. Thin to the strongest seedling per station after germination.

Planting Outdoors:

  • Plant in rich, fertile, well-drained soil in a position of full sun.
  • Space plants 90cm (36 inches) apart.
  • Cover young plants with protective netting or fleece to deter birds and insects.

Care:

  • Apply a thick mulch of organic matter around plants to conserve soil moisture.
  • Ensure consistent watering, especially during dry periods.

Compatibility:

  • This variety is a *Cucurbita pepo*.
  • It is a half-hardy annual.
  • Beneficial for attracting pollinating insects.
