📅 Is March a Good Time to Sow Aubergine Seeds?
Yes — early to mid-March is still a suitable time to sow aubergine seeds in the UK.
While mid-February to early March is often considered ideal, March sowing:
- Avoids the low light levels of winter
- Produces sturdier seedlings
- Reduces the risk of leggy growth
For gardeners without grow lights, March can actually be a safer option.
🌡️ Temperature Still Matters in March
Even in March, aubergines need warmth to germinate.
- Ideal compost temperature: 22–28°C
- Below 18°C: germination slows or becomes unreliable
Indoor sowing is still essential, as outdoor and greenhouse temperatures are usually too low.
🌱 What to Expect From March-Sown Aubergines
Compared to earlier sowings, March-sown plants often:
- Germinate more evenly
- Grow more steadily
- Need less indoor care time
They may flower slightly later, but often catch up during warm summer weather.
🌞 Light Levels in March
One of the biggest advantages of March sowing is improved daylight.
- Days are longer
- Sunlight is stronger
- Seedlings are less likely to stretch
This leads to compact, healthy plants with thicker stems.
🌿 Is There a Cut-Off Point in March?
- Early March: ideal
- Mid-March: still very workable
- Late March: possible, but growing time becomes tighter
Late March sowings benefit most from greenhouse growing rather than outdoor planting.
🏡 Greenhouse vs Outdoor Growing After March Sowing
March-sown aubergines perform best:
- In greenhouses
- In polytunnels
- In large containers that can be moved to warm spots
Outdoor growing becomes more challenging the later sowing is delayed.
🚫 Common Mistakes With March Sowing
- Assuming no heat is needed
- Moving plants outside too early
- Overwatering in cooler rooms
March sowing still requires care and warmth during early growth.
🧠 Key Takeaway
Sowing aubergine seeds in March is not too late and is often a very sensible choice for UK gardeners. With better light levels and correct warmth, March-sown plants can grow just as well as earlier ones and often prove easier to manage.
If you’ve missed February, don’t worry — March is still very much in play.
