Competition for space in the cold frame is hotting up by the middle of April, so even though it is a little earlier than recommended by Robinsons, my precious onion seedlings are planted out on 19th
Before planting out, I lightly fork over the beds, remove all weeds, and rake in a dose of chicken manure pellets. The top 10cm or so is primarily made up of the well rotted organic matter that had been added previously. Spacing is a bit of an issue – I want to give each of my seedlings a new home but have 46 plants to fit in (26 white and 20 red).
In the end I go for a staggered row arrangement. I plant the seedlings 25cm apart in each row, and the staggered rows are 20cm apart (approx). I water them in and then wish them well.
