I bought three boxes of this cuz it was on offer. Three 3kg boxes. I live in a high rise, so traipsing up & down 6 flights of stairs to the communal garden is hardwork & with nowhere to store fertilisers safely, these boxes have been a lifesaver - I take as many as needed & spread the pellets all over the soil & into the flowerpots on all my plants, except the veg/the results were astounding..the roses started to flower within 48hrs of use, as did the pansies. Now I put a sprinkling out every few weeks just before rain is expected & nature does the rest & I found buying direct from the manufacturer to be the most affordable & the cheapest option. So well done to them 10/10
