Pricking out seedlings
Pricking Out Seedlings
Once your seeds have germinated and the young plants are large enough to handle comfortably, they should be moved into individual pots. This process is known as pricking out.
The aim is to transplant seedlings without “checking” them. Checking means disturbing or damaging the roots so badly that growth slows or becomes stunted. Careful handling is essential.
When to Prick Out
Seedlings are ready when they have developed their second pair of true leaves and are strong enough to be handled easily.
How to Handle Seedlings
Always hold a seedling by one of its leaves — preferably the second pair — never by the stem.
If a leaf is damaged, the plant will simply grow new leaves.
If the stem is damaged, however, the plant cannot repair it, and the seedling is likely to fail.
Lifting the Seedling
Using a dibber or a short stick:
- Gently ease the seedling out of the compost.
- Lift it carefully, keeping as much of the root system intact as possible.
- Avoid tugging or pulling.
Potting On
Prepare a small pot — typically 75–100 mm (3–4 inches) in diameter, depending on the plant.
- Fill the pot with fresh compost.
- Make a hole large enough to accommodate the roots without bending them.
- Lower the seedling into the hole so it sits at the same depth it was growing in the seed tray.
- Lightly press the compost around the roots with your fingers.
Do not ram the compost down firmly with a stick. Gentle pressure is sufficient.
Aftercare
Water the seedling in carefully using a watering can fitted with a fine rose. This settles the compost naturally around the roots and removes air pockets.
The seedling may lean slightly after watering, but it will quickly straighten itself as it establishes.
Handled correctly, seedlings will continue growing without any setback, ensuring strong, steady development.
