Tomato seedlings grow fast and are hungry feeders, so keep them in vigorous growth by potting on as soon as they have rooted through their containers.
The more space they’re given in the greenhouse, the stronger they’ll be, as tightly packed plants tend to be drawn upwards with weak stems.
Discover how to pot on tomato seedlings, below.
You Will Need
- Tomato plants
- Multi-purpose, peat-free compost
Handle seedlings with care when easing them out of their containers for repotting to minimise root disturbance.
The tiny leaves below the first true leaves can be removed so that when the plant is potted deep into the compost, they’ll not rot.
Lower the plant into a larger pot so that the true leaves are just above the compost surface, filling in gaps and topping up the pot with multi-purpose compost. The stem below the surface will grow more roots, to boost the crop.
Planting out your tomatoes
When the time comes to plant out your tomatoes – usually done after the last frosts in May – choose a sunny, sheltered spot which will boost the flavour of your tomatoes, and how many you harvest. If growing in a greenhouse, try planting basil alongside the plants, which enjoys the same conditions.
