About this product

The details that matter

Organic 'Triamble' winter squash Seeds (Cucurbita maxima). This heirloom stands out for unique three-lobed fruit, smooth deep-green skin, and a sculptural form. Its dense dry flesh has a rich nutty flavour particularly suited to roasting, purées, soups, and stews. Triamble is an annual open-pollinated variety. The packet contains approximately 4 seeds certified organic by Ecocert Canada. Kew recognizes Cucurbita maxima as the accepted botanical name in the Cucurbitaceae family and confirms its use as food. Gaia also identifies the young leaves and flowers as edible. When properly cured, the mature fruit extends the garden harvest well into the colder season and brings an unusual shape to winter meals. For practical seed starting, growing from seed succeeds best when the verified product depth, moisture and temperature guidance is followed.

Soak seed in warm water for up to 24 hours and lightly scarify the coat to improve germination. Start seed indoors three to four weeks before the last frost. Sow 1 inch deep and maintain the medium at 25 to 32°C, preferably around 27 to 35°C; germination generally takes 7 to 10 days. Transplant only after all frost risk has passed and soil reaches approximately 25°C. Space plants 15 to 18 inches apart and rows 36 to 60 inches apart. Harden seedlings gradually for several days before planting outdoors. Move seedlings into bright light after emergence and water gently to settle the roots. Protect the young plants from sudden cold nights during establishment. Use the product details as a clear guide on how to start seeds while keeping the growing medium evenly moist, never saturated. For indoor seed starting, count back from local conditions and frost dates to decide when to start indoor seeds.

Grow Triamble in full sun and rich loose soil that remains evenly moist while draining well. Plants reach approximately 12 to 18 inches high and spread 3 to 5 feet. Maturity occurs in 90 to 100 days. Harvest when colour is rich, the rind resists a fingernail, and the ground spot becomes cream, gold, or orange. Cut fruit with approximately 2 inches of stem, then cure in a warm dry place. Store cured fruit at 10 to 12°C with 55 to 75% relative humidity and good airflow. Lift fruit from underneath to preserve the protective stem, and inspect it regularly during storage so any damaged fruit can be used first.

How to use it

Uses in the garden

In the garden, place Triamble winter squash; three-lobed Triamble squash according to its habit, vigour, and access for harvest. Allow stems to trail through a sunny bed with 3 to 5 feet of spread.

Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season. Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots. Before outdoor planting, gradually acclimatize young plants to wind, sunlight, and changing temperatures over several days. Follow the stated spacing so air can move between plants and each plant receives adequate light, water, and nutrients. Water at soil level when the surface begins to dry, then adjust frequency for weather, drainage, and container volume.
