Expected height: 61 to 91.4 cm (24 to 36 in). For practical seed starting, growing from seed succeeds best when the verified product depth, moisture and temperature guidance is followed.

Start seedlings indoors 10 to 12 weeks before planting. Transplant is highly recommended. It can be transplanted 2 to 3 weeks before the last frost date. May bolt if the room temperature is below 12 °C in the day and 4 °C at night. 1/2 in 21 to 23 °C. Germination generally takes 14 to 30 days under the recommended conditions. Space plants 30.5 to 45.7 cm (12 to 18 in). 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.

Harvest while curds are still tight. Tie leaves together for a blanched effect. The stalk colour will lighten and its flavour will become milder. Cool right after harvesting. Tomato, Spinach, Onion, Beans, Sage, Thyme, Cabbage, Basil, Tansy. The packet contains 50 seeds. Confirmed edible parts: Leaves and tender stems.

Growing method

For Red Stalk Celery, follow these sowing and growing guidelines for the variety. Start seedlings indoors 10 to 12 weeks before planting. Transplant is highly recommended. It can be transplanted 2 to 3 weeks before the last frost date. May bolt if the room temperature is below 12 °C in the day and 4 °C at night. 1/2 in 21 to 23 °C. 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. This seed starting sequence supports reliable growing from seed while preserving the product-specific depth and temperature facts.

Frequently asked questions

Your questions,answered.

How many 'Red Stalk' Celery seeds are in the packet?

For Red Stalk Celery, the packet information states: Approximately 50 seeds · lot GO22063 · germination >85%. This wording preserves the commercial approximation when one is provided and helps plan the number of containers or the length of the row without turning an estimate into a guaranteed count. Keep the packet closed in a cool, dry, dark place until sowing time. Keep the label with the seedlings so the variety remains correctly identified throughout the season. Use clean containers and write the sowing date on a water-resistant label. Avoid exposing unused seed to moisture or large temperature swings.

How should I start 'Red Stalk' Celery seeds in Canada?

For Red Stalk Celery, follow the detailed sowing schedule in the product record. The recommended method is sowing from seed, at a depth of 13 mm (1/2 in). Follow these product-specific directions and adjust timing to the average last-frost date in your area. Moisten the growing medium before placing the seed so the first watering does not displace it. Label every container and maintain even moisture without allowing standing water. Move seedlings into bright light as soon as they emerge to encourage balanced growth. Thin carefully when several seedlings compete for the same space. For seed starting, label the cultivar and use the stated sowing depth instead of a generic estimate.

How long do 'Red Stalk' Celery seeds take to germinate?

For Red Stalk Celery, the stated germination period is generally 14 to 30 days under the recommended conditions, at a germination temperature of 21 to 23 °C. Keep these conditions as steady as practical while allowing excess water to drain away. The temperature of the growing medium matters more than the surrounding air during this stage. Check moisture below the surface before watering again and avoid saturating the medium. Good air circulation helps young plants remain vigorous after emergence. Wait until the normal germination window has passed before assuming a seed will not emerge. When growing from seed, keep conditions stable for the full stated germination window before disturbing the mix.

Where should I grow 'Red Stalk' Celery in the garden?

For Red Stalk Celery, the recommended exposure is Full sun to partial shade. The stated spacing guideline is 30 to 46 cm (12-18″). For container growing, the product record recommends: 5 to 10 L per plant with free drainage. Allow for the mature habit so neighbouring plants do not restrict light or access for harvest. Choose a site that is easy to water and leave enough room for air to circulate around the foliage. In a container, make sure several holes allow excess water to drain freely. A light mulch can steady moisture after the soil has warmed and plants are established. Place plants where their growth can be observed and stress can be addressed early.

When and how should I harvest 'Red Stalk' Celery?

For Red Stalk Celery, the confirmed edible parts are: Leaves and tender stems. Harvest them at the stage stated in the product record, then sort the crop before preparation. Use only the parts correctly identified as edible for this plant. Use a clean tool and handle the harvest carefully to avoid unnecessary injury to the plant. Harvest in dry weather when practical and remove damaged portions promptly. Wash only the parts intended for the kitchen and refrigerate perishable produce promptly. Never eat a plant part whose identity or edibility is uncertain.
