Altai Orange Tomato Heirloom Seeds

Bring bright orange color and generous slices to your summer table with Altai Orange, also known as Altaiskiy Oranzhevyi. This Russian heirloom produces large beefsteak tomatoes with meaty, smooth-textured flesh, a lightly fruity aroma, and relatively few seeds. Slice one for a sandwich or combine it with red tomatoes for a colorful garden salad.

Why Grow Altai Orange?

• Large orange beefsteaks: Fruits commonly weigh approximately 12–16 ounces, with size varying by conditions.
• Meaty texture: Thick orange flesh and relatively few seeds make satisfying sandwich slices.
• Early for a large slicer: Listed maturity is approximately 65–70 days from transplant.
• Indeterminate growth: Supported vines can continue growing and producing during favorable weather.
• Open-pollinated heirloom: Non-GMO seed for a distinctive kitchen-garden tomato.

Planting and Growing

Start seeds indoors 6–8 weeks before your intended transplant date. Sow approximately ¼ inch deep in seed-starting mix, keep warm for germination, and provide strong light. Harden off seedlings gradually before transplanting after frost danger has passed and growing conditions have warmed.

Choose full sun and fertile, well-drained soil. Install a sturdy stake, cage, or trellis at planting time to support the vines and large fruit. Water consistently at soil level and mulch to help conserve moisture. Allow airflow between plants and tie developing stems to their support as needed.

In a square foot garden, use 1 plant per sq ft (trellis required) only with dedicated vertical training and regular pruning. Allow more space for multi-stemmed or caged plants. Russian origins do not make this tomato frost-hardy; protect plants from cold weather.
