Planting onion sets

Early April I started to plant some white onion sets I bought from The Range. I was also kindly given some red onion sets from a neighbour on the allotment.  I planted the onions sets out after I had dug some compost into the soil.
More membrane arrived from Amazon so I could continue covering the ground around the shed and vegetable bed. Unfortunately we had a big rainfall and the ground became very boggy :(  But on a positive note it made the soil very easy to dig over and add compost to help with the clay soil problem.
