Cosmonaut Volkov Heirloom Tomato Seeds

Bring rich, old-fashioned tomato flavor to your summer table. Cosmonaut Volkov is a Ukrainian heirloom prized for juicy, slightly flattened red tomatoes with a deep, balanced sweetness and lively tang. Slice one onto a sandwich, serve thick wedges with salt and basil, or make it the centerpiece of a fresh garden salad.

Why Grow Cosmonaut Volkov?

• Rich, sweet-tangy flavor: Full-bodied tomato taste and plenty of juice make this a rewarding fresh-eating slicer.
• Generously sized red fruit: Slightly flattened globes typically around 8–12 ounces, with natural variation in size and gentle shoulder ribbing.
• Relatively early harvest: Plan on approximately 65–75 days from transplant, depending on conditions.
• Ukrainian heritage: Named in honor of cosmonaut Vladislav Volkov, this heirloom brings a memorable story to the garden.
• Indeterminate growth: Supported vines continue growing and setting fruit while conditions remain favorable.
• Open-pollinated heirloom: A seed-saving choice for gardeners who want to grow a favorite again.

Planting and Growing

Start indoors 6–8 weeks before your intended transplant date. Sow approximately ¼ inch deep in seed-starting mix, provide warmth and strong light, and harden seedlings off gradually. Transplant after frost danger has passed and soil has warmed. Choose full sun and fertile, well-drained soil.

Install sturdy cages, stakes, or a trellis early to support the vines and developing fruit. Water consistently at soil level and mulch to conserve moisture. Maintain airflow while keeping healthy foliage to shade fruit. Sudden changes in moisture can cause cracking, particularly as fruit ripens.

For square foot gardening, use 1 plant per sq ft (trellis required) with dedicated vertical training and regular pruning. Allow additional canopy space for caged or multi-stemmed plants. Although this variety has a reputation for producing in cooler growing regions, it remains frost-tender and needs a warm-season planting window.
