25+ Mushroom Basket Tomato Seeds, Heirloom, Solanum Lycopersicum

Mushroom Basket Tomato Seeds for Planting – Non-GMO Heirloom Seeds (Solanum lycopersicum) produce large, deeply ribbed tomatoes with an unusual pleated shape that gives this variety its distinctive “mushroom basket” appearance. This Russian heirloom typically produces 12–16 oz fruits with attractive pink to red coloring, meaty flesh, relatively few seeds, and a pleasant sweet-tangy tomato flavor. Mushroom Basket is especially valued as a gourmet slicing and stuffing tomato because its dramatic ridges create beautiful cross-sections when cut. It is excellent for sandwiches, salads, fresh platters, stuffing, roasting, sauces, and decorative culinary presentations. The plants are vigorous, productive, and indeterminate, continuing to grow and produce throughout the season until frost.

Planting Season

Best planted in: Spring & Early Summer (Warm-Season Crop)

Start seeds indoors approximately 6–8 weeks before the last expected spring frost. Transplant outdoors only after frost danger has passed and the soil has warmed. Tomatoes perform best when nighttime temperatures are above approximately 52°F (11°C) and daytime temperatures are consistently above 60°F (16°C).

Choose a warm growing season with plenty of direct sunlight. Avoid exposing young plants to frost or prolonged cold conditions, which can stunt growth and reduce yields.

How to Grow Mushroom Basket Tomato Seeds

Start seeds indoors in trays or small pots filled with moist seed-starting mix.

Sow seeds approximately ¼ inch deep.

Maintain soil temperatures between approximately 75–85°F (24–29°C) for reliable germination.

Keep the growing medium evenly moist but not waterlogged.

Seeds typically germinate within approximately 6–14 days under favorable conditions.

Provide strong light after germination. Transplant seedlings into larger pots after true leaves develop, then harden them outdoors for approximately 1–2 weeks before planting in the garden.

Choose a location receiving at least 6–8 hours of direct sunlight daily and provide fertile, moist but well-drained soil.

Space plants approximately 36–48 inches apart, with rows about 4–5 feet apart. Mushroom Basket is an indeterminate variety and develops vigorous vines, so provide a strong cage, stake, or trellis at planting time.

Container growing is possible in a large container with excellent drainage and sturdy support.

Mix compost or aged organic matter into the soil before planting to encourage healthy root development and steady growth.

How to Care for Mushroom Basket Tomato Plants

Water deeply and consistently throughout the growing season, especially during flowering and fruit development. Avoid allowing the soil to alternate between very dry and excessively wet conditions.

Water near the base of the plant whenever possible and keep foliage relatively dry to reduce disease pressure.

Apply mulch around established plants to conserve moisture, suppress weeds, and reduce soil splash.

Feed with a balanced tomato fertilizer during active growth. Avoid excessive nitrogen because it can encourage vigorous foliage at the expense of fruit production.

Secure vines and heavy fruiting branches to sturdy supports. The large, deeply pleated fruits can become heavy as they mature.

Remove yellowing or diseased lower leaves to improve airflow and monitor for common tomato pests such as aphids, spider mites, whiteflies, tomato hornworms, and stink bugs.

Mushroom Basket Tomatoes generally mature approximately 75 days after transplanting. Mature fruits commonly reach 12–16 oz and develop their characteristic deeply ribbed shape.

Harvest when the fruits develop a rich pink to red color and become slightly yielding when gently pressed.

For the best flavor, allow fruits to ripen fully on the vine whenever possible. Store ripe tomatoes at room temperature and use them within several days for the best texture and flavor.
