These seedballs make it easy to grow your own supply of crispy salad leaves in beds, borders or pots.

Each ball contains a blend of Greek Cress, Red Russian Kale, Green Frills Mustard, Red Frills Mustard and Salad Rocket seeds, mixed with peat-free compost and a pinch of chilli powder to deter pests. A dried clay casing offers extra protection from birds, ants and mice.

No planting required, simply scatter on the surface of soil or compost from spring to the end of summer, water well and nature will do the rest.

Use around 20 balls per square metre for large areas or 3-5 in a medium sized pot. Sprouts should be seen in 1-2 weeks although regular watering may speed up the process.

Each individual seedball contains approximately 30 seeds.
