Guide To Plant Sizes

Seedlings: Seedlings are young plants that have grown from seeds and are still small, usually with just a few leaves. They are in the early stages of growth and are ready to be potted on or planted outdoors to continue developing.


Plug Plants: A wide range of our varieties come in plug size, including Strawberries, Tomatoes, Chillis, Peppers, Cucumbers and Courgettes. Grown in individual cells with a bio-degradable membrane that will break down in the soil, no need to remove before planting. Pot and grow on to form larger plants that can be planted later in the season. Protect from frost if necessary.


9cm Plants: Our 9cm plants are larger and much more established than our plug ranges, meaning they are ready to plant out straight away. These will establish quickly and produce flower and fruit much quicker than smaller plugs. Protect from frost if required.


13cm Plants: A substantial plant with many already developed flowers or even early onset of fruit if the season has been early. Great for filling in gaps or plating into patio containers.


Grafted Plants: Grafted plants are created by joining together two different plant varieties, typically by attaching the stem of one onto the root system of another. This process allows for desirable traits, such as disease resistance or better fruit production, to be combined into a single plant.


How To Grow

When you receive your spring onion seedlings, start by hardening them off. Place the seedlings in a sheltered, bright spot outdoors for a few days to help them adjust to the outdoor conditions.

Choose a sunny, well-drained spot enriched with organic compost. Space the seedlings about 10–15cm apart to allow room for growth. Water thoroughly after planting and maintain consistent moisture without waterlogging the soil. A light feeding of a balanced liquid fertiliser will support healthy development.

Monitor your young plants for pests and adjust watering during dry spells. With proper care, your spring onion seedlings will thrive, delivering a continuous supply of tender, flavourful onions throughout the growing season.
