Getting the polytunnel ready to go is taking forever, but while we are getting on with that, little seedlings are happily growing on windowsills. The seeds that are not already planted into toilet paper tubes are planted densely in (cardboard) trays.
They can’t stay in those trays for too long, as they are far too closely spaced and nutrients will be depleted long before they are ready to plant out. But I will prick them out into their own modules once they have their first set or two of proper leaves. (Being careful not to damage the stem or roots.)
Placing the seeds so closely allows me to germinate a larger number in a limited space, when warm windowsill space is at a premium. Stock that will be used to populate the polytunnel is growing apace.
