📅 When to Sow Cherry Tomato Seeds (UK)
🌱 Best Sowing Time
✔ Late February to March
Cherry tomato seeds are best sown indoors because they need warmth to germinate.
✔ sow in seed trays or small pots
✔ keep compost warm and moist
✔ place in a bright position
Sowing earlier than February usually results in weak, leggy plants unless grow lights are used.
🌱 Later Sowing Option
✔ Early April sowing still works well
✔ plants often catch up quickly
✔ ideal for beginners with limited space
🏡 When to Plant Cherry Tomatoes in a Greenhouse
🌿 Greenhouse Planting Time
✔ Late April to early May
Cherry tomatoes can be planted earlier in a greenhouse because they are protected from frost.
✔ suitable for unheated greenhouses
✔ fleece may be needed on cold nights
✔ soil warms faster under cover
Greenhouse cherry tomatoes usually crop earlier and more reliably.
🌤️ When to Plant Cherry Tomatoes Outdoors
🌱 Outdoor Planting Time
✔ Late May to early June
Only plant cherry tomatoes outside when:
✔ all risk of frost has passed
✔ night temperatures stay above 10°C
✔ plants have been hardened off
In colder areas, outdoor planting may be delayed until early June.
🌡️ Soil Temperature and Growing Conditions
Cherry tomatoes thrive when:
✔ soil temperature is 12–15°C or warmer
✔ soil is free-draining and fertile
✔ plants receive full sun
Cold soil slows growth and increases disease risk.
🌍 Regional Differences in the UK
Cold Areas (Scotland, northern England, higher ground)
✔ sow seeds at the same time
✔ plant outdoors later
✔ greenhouse growing is strongly recommended
Mild Areas (southern England, coastal regions)
✔ earlier greenhouse planting possible
✔ outdoor planting may begin slightly earlier
Always prioritise temperature over dates.
🪴 Growing Cherry Tomatoes in Pots
Cherry tomatoes are excellent container plants.
✔ use large pots (minimum 30 cm wide)
✔ ensure good drainage
✔ feed regularly once flowering starts
Potted plants can be moved to shelter during cold spells.
❄️ What If Frost Hits After Planting?
Cherry tomatoes are not frost tolerant.
✔ even light frost can kill plants
✔ cover immediately with fleece
✔ move container plants indoors if possible
Never plant outdoors before frost risk has passed.
🚫 Common Cherry Tomato Planting Mistakes
❌ sowing seeds too early without enough light
❌ planting outdoors before frost risk ends
❌ skipping hardening off
❌ planting into cold soil
Patience leads to stronger plants and heavier crops.
