Out of curiosity, in case they've been mis-sold, I've had a look online at the instructions. For the second and third packs, the first two instructions are the following, which is what I was hoping to see.....
1. PREPARE
Firstly, we must prepare the area we want the final flower display.
Choose a nice sunny spot in the garden, maybe in garden borders, in front of garden fences, or even in large patio planters.
Remove any stones, weeds and debris from the soil.
2. RAKE
Once the soil is free from debris, rake over to break up the clumps and prepare the growing medium for the seeds.
Ideally rake the soil to a depth of 2.5 - 4 cm, keeping the excess soil to one side to cover the seeds later.
