How to Grow Beefsteak Tomatoes (UK Guide)

Beefsteak tomatoes are large, meaty, and perfect for slicing, sandwiches and cooking. However, they are more demanding than cherry tomatoes and require a longer growing season.

This guide explains how to grow beefsteak tomatoes successfully in the UK, including greenhouse tips, feeding and managing heavy fruit.

For the full tomato growing system, see TOMATOES: HOW TO GROW, BEST VARIETIES, PROBLEMS & EXPERT TIPS (UK GUIDE).

Are Beefsteak Tomatoes Suitable for the UK?

Yes — but they perform best:

  • In a greenhouse
  • In a polytunnel
  • In very warm, sheltered outdoor spots

They need:

  • A long season
  • Strong feeding
  • Consistent warmth

They are less reliable outdoors in cooler regions.

Best Beefsteak Varieties for UK Gardeners

Look for:

  • Reliable greenhouse types
  • Early-maturing beefsteaks
  • Disease-resistant varieties

See BEST BEEFSTEAK TOMATO VARIETIES for detailed recommendations.

When to Sow Beefsteak Tomatoes

Sow:

  • Late February to mid-March if growing under cover
  • March for most UK growers

Because they take longer to mature, slightly earlier sowing can help — but only with sufficient light.

See CAN YOU SOW TOMATO SEEDS IN FEBRUARY? for early-start advice.

Growing Beefsteak Tomatoes in a Greenhouse

Greenhouse growing is strongly recommended.

Beefsteak tomatoes require:

  • Warm night temperatures
  • Consistent feeding
  • Strong support systems

They are usually cordon types and grow tall.

Supporting Beefsteak Tomatoes

Support is critical.

Use:

  • Strong bamboo canes
  • Overhead string systems
  • Heavy-duty ties

Fruit can become very heavy and snap stems if unsupported.

Pruning Beefsteak Tomatoes

Remove:

  • Side shoots weekly
  • Excess flower trusses if plant is struggling

Many growers limit to 4–6 trusses to ensure large fruit size.

Feeding Beefsteak Tomatoes

These are extremely heavy feeders.

Feed:

  • Weekly once flowering starts
  • With high-potash fertiliser

Insufficient feeding leads to:

  • Small fruit
  • Poor flavour
  • Blossom drop

See BEST FEED FOR TOMATOES for recommendations.

Watering Beefsteak Tomatoes

Consistent watering is essential.

Fluctuating moisture causes:

  • Blossom end rot
  • Splitting
  • Irregular fruit shape

Water deeply and regularly.

Why Beefsteak Tomatoes Sometimes Fail in the UK

Common issues include:

  • Insufficient heat
  • Poor pollination
  • Not enough feeding
  • Growing outdoors in cold summers

If growing outdoors, choose the warmest, sunniest position possible.

Harvesting Beefsteak Tomatoes

Beefsteaks are ready when:

  • Fully coloured
  • Slightly soft
  • Heavy and firm

Do not leave overly ripe fruit on the plant, as this reduces further production.

Final Thoughts: Are Beefsteak Tomatoes Worth It?

Yes — if you can provide:

  • Warmth
  • Feeding
  • Strong support
  • A long season

They require more effort than cherry types but produce impressive, restaurant-quality fruit.
