Grow tomatoes outdoors in a sunny, sheltered spot. This method is common in UK gardens but requires careful timing due to frost risks.

1
Sow Seeds Indoors

7 Feb - 22 Feb

Sow seeds indoors in modules or small pots around 7th February - 22nd February. Use a heated propagator or warm windowsill at for germination. Keep the compost moist but not waterlogged.

2
Prick Out Seedlings

28 Feb - 7 Mar

Once seedlings develop their first true leaves, prick them out into individual pots around 28th February - 7th March. Handle seedlings by the leaves to avoid stem damage and plant at the same depth as before.

3
Pot On Plants

14 Mar - 21 Mar

Move plants into larger pots around 14th March - 21st March to prevent root restriction. Use a good quality potting compost and water well after repotting to settle the roots.

4
Harden Off Plants

7 Apr - 14 Apr

Gradually acclimatise plants to outdoor conditions over 10-14 days starting around 7th April - 14th April. Place them outside in a sheltered spot during the day and bring in at night, increasing exposure each day.

5
Transplant Outdoors

14 Apr - 21 Apr

Plant tomatoes in their final position around 14th April - 21st April after frost risk has passed. Space plants apart in fertile, well-drained soil. Water in well and consider using cloches or fleece for extra protection.

6
Support and Train Plants

24 Apr - 1 May

Provide stakes or cages for support from 24th April. For cordon varieties, remove side shoots regularly to direct energy into the main stem. Pinch out the main growing tip after 4-6 trusses have set to force ripening in the UK climate.

7
Feed Plants

25 Nov - 1 May
every 2 weeks

Apply a high-potassium liquid fertiliser every 14 days starting around 25th November and continuing until 1st May. This supports flowering and fruit development. Water plants regularly to prevent blossom end rot.

8
Harvest Tomatoes

25 Nov - 1 Jul

Pick fruits as they ripen from 25th November until 1st July. Harvest regularly to encourage more production. If frost threatens, pick green tomatoes and ripen indoors on a windowsill.

Why Companion Planting Matters

Companion planting can help deter pests, improve pollination, enhance growth, and maximize garden space. Some plants release chemicals that repel pests or attract beneficial insects, while others can improve soil quality or provide shade for sensitive plants.
