from what your saying it seems to be a good idea to start our onion sets of in pots or trays being mindful of root disturbance we have both modules and pots we can use and i take your point about how much compost we mite use obviously taking into account both the pot or modules size
however because of the amount of sets we plan to set I don't think we will have enough room in either the poly tunnel or greenhouses for all the sets so some sets will to be direct sown and I know I have had some good sound advise from some of our fellow gardeners in the past how we should prep the ground prior to planting out an onion bed or beds
so for the direct planting I think I'm going to first of prep the ground as said then make a V channel put some compost in the channel then plant the sets in the compost then cover the sets
do you think that method mite be a good way of starting of planting onion sets and shallots ?
this seasons onion trials
still on the subject of planting out onions and I may have commented on this before I've got an idea of planting my onion plants and raised sets in Bio-Degradable mulch film strips so there weed free because I have the idea by using this film more goodness will be put into the growing rather than feeding the weeds and it may cause less damage by hand weeding as weeding is a very time consuming job and one thing I hate doing I intend to leave the rows about a foot apart not covered between the rows so that can be easily weeded and if I need to liquid feed so as I said its going to be on a trial basis to see if this method works
not sure
