• Each seed box contains 6 seed balls • Unit cost £1.60 plus VAT • RRP £3.50 • Sold in packs of 10 • This item is not barcoded Designed by the London Wildlife Trust, this new set of three seed boxes each features a different British butterfly illustration and a unique butterfly friendly wildflower mix. 25p is donated by Seedball to the London Wildlife Trust for each box sold (this information is included on the label). A small card is also included to explain what the balls are and how to use them- they’re incredibly easy to use – simply scatter on top of soil/compost (no digging or expertise required!) and nature will do the rest. Each box is 5.8cm x 3.7cm x 1.5cm (like an old small matchbox size), and contains 6 seed balls to grow beautiful wildflowers in a window box, balcony pot or garden bed. One box will cover 1-2 pots. We make the seed balls ourselves from our HQ in North London - from a mixture of UK native wildflower seeds, clay, peat-free compost and chilli powder. The clay protects the seeds from wildlife.
