Seeds & planting
Thin crowded seedlings
Identify the crop and mark the plants to keep at the recommended final spacing.
When to do it
When seedlings can be identified and before they compete heavily.
What you need
- Packet spacing
- Small scissors
- Gentle water
How to do it
- Identify the crop and mark the plants to keep at the recommended final spacing.
- Moisten the soil if it is dry. Remove weaker or crowded seedlings, supporting nearby plants.
- Where roots are intertwined, snip surplus seedlings at soil level instead of pulling and disturbing the survivors.
- Water lightly if roots were disturbed. Recheck spacing as plants develop; do not assume every thinning is edible.
What success looks like
- Retained seedlings remain firm and have growing room.
Watch out for
- Keeping every seedling and producing a crowded weak crop.
