FAQs

Do I need to prune Super Marmande tomatoes?

No, the 'semi-bush' habit means you do not need to pinch out side shoots. This significantly simplifies the growing process.

What size pot is best for growing Super Marmande?

For container growing, a pot of at least 10-15 liters (approx. 3-4 gallons) is recommended to provide adequate root space.

When is the best time to sow the seeds?

Sow seeds indoors or in a greenhouse from late February to April. Harden off and plant out after the last frost in May or June.

What are the tomatoes best used for?

Super Marmande tomatoes are versatile and excellent for salads, sandwiches, roasting, and stuffing due to their meaty texture and sweet flavor.

Why is it recommended by the Royal Horticultural Society?

RHS recommendation indicates the variety has undergone rigorous trials and demonstrated excellent performance in terms of yield, disease resistance, and fruit quality.

Can I grow these outdoors in a colder climate?

While they can be grown outdoors, they perform best in a sunny, sheltered location. For cooler climates or to ensure a better yield, growing in a greenhouse or polytunnel is recommended.

Troubleshooting

Seeds not germinating

Ensure seeds are kept at the correct temperature (18-21°C) and are not sown too deeply. Check seed packet for viability date.

Leggy seedlings

Seedlings are likely not receiving enough light. Move them to a brighter location or provide supplemental grow light. Ensure temperature is not too high.

Blossom end rot on fruit

This is often caused by inconsistent watering or calcium deficiency. Ensure soil remains evenly moist and consider a calcium supplement if problems persist.

Poor fruit set

Ensure adequate sunlight, temperature, and pollination. In greenhouses, consider gently shaking plants or using a small brush to aid pollination.

Setup, Compatibility & Care

Sowing Seeds:

  1. Sow seeds indoors or in a greenhouse from late February to April.
  2. Use a good quality seed compost. Sow seeds thinly about 0.5cm deep in trays or pots.
  3. Cover lightly with compost and water gently.
  4. Maintain a temperature of 18-21°C for germination.
  5. Once seedlings are large enough to handle, transplant them into individual pots.

Planting Out:

  1. Harden off seedlings gradually before planting outdoors or into their final greenhouse positions.
  2. Plant out in May or June, after the risk of frost has passed.
  3. Space plants about 45-60cm apart.
  4. Choose a sunny, sheltered position. For best results, provide support such as stakes or cages.

Care:

  • Watering: Water consistently, especially during dry spells, to prevent fruit splitting.
  • Feeding: Once fruits start to set, feed regularly with a high-potash fertilizer.
  • Pruning: Unlike many tomato varieties, side shoots do not need to be pinched.

Compatibility:

This variety is well-suited for pots, containers, grow bags, greenhouse cultivation, and small garden plots.
