🍆 Sowing Aubergine Seeds: How Many Seeds Per Pot?
Knowing how many aubergine seeds to sow per pot helps improve germination success while avoiding overcrowding and unnecessary thinning later. The right number depends on seed quality, container size, and how confident you are in your setup.

Using seed trays or module pots keeps seedlings organised, improves drainage, and makes potting on easier with minimal root disturbance.
🌱 The Ideal Number of Seeds Per Pot
For most UK gardeners, the best approach is to sow:
- 1–2 seeds per pot
This gives a good balance between:
- Germination success
- Efficient use of space
- Minimal root disturbance later
If both seeds germinate, you can keep the strongest seedling.
🪴 Why Not Sow More Seeds Per Pot?
Sowing too many seeds in one pot can cause:
- Crowded seedlings competing for light
- Increased legginess
- Tangled roots
- More transplant stress
Aubergines respond best to minimal early competition.
🌱 When to Sow Just One Seed Per Pot
Sowing a single seed works well if:
- Seeds are fresh and high quality
- Germination conditions are warm and stable
- You have limited space
This avoids thinning altogether and reduces waste.
🌱 When Two Seeds Per Pot Is Better
Sowing two seeds is useful when:
- Seeds are older or home-saved
- You want a backup in case one fails
- Germination conditions may be less reliable
Always remove the weaker seedling early if both sprout.
✂️ How to Thin Seedlings Correctly
If two seeds germinate:
- Do not pull out the weaker one
- Snip it off at soil level with scissors
Pulling can disturb the roots of the remaining seedling.
🌡️ Container Size Matters
- Small pots or modules (7–9cm) suit 1–2 seeds
- Very small cells should only contain one seed
Correct spacing supports strong early growth.
🧠 Key Takeaway
For healthy aubergine seedlings, sow 1–2 seeds per pot. This maximises germination success while keeping seedlings strong, uncrowded, and easy to manage.
Less crowding early on leads to better plants later.
