Carrying on the thoughts from the other day.
It has to be said there is an elephant in the room on all this – Mother Nature herself – unpredictable and changeable – but we can deal with her as a variable in the calculations.
Following the logic of the last post:
I effectively have 8 months a year when its possible to grow Onions outside – March to October – giving us about 35 weeks. The average length of growth of an onion is about 20 weeks. In the last post I explained that using 7 Onions a week would require a row of 140 Onions growing all the time – with 7 pulled and 7 planted each week to keep this going.
With our growing period this means I cannot achieve this balance. It simply does not work. If I waited until week 20 to start pulling and re-planting I couldn’t replant because I would only have 15 growing weeks left and I need 20. If I put in 7 Onions each week from week 1 I would need more than the 58′ row I had calculated – but this would still have to stop at 15 weeks to allow the 20 week growing time. Even for allowing a slightly longer growing period in a Polytunnel this still does not work
So to make sure I have enough Onions for my weekly cooking I have to go back to the last Algorithm of the last post:
Live Grow + Storage Grow = Self Sufficiency.
By working through this logic we can see that actually the problem is not the growing – we have enough of a window to grow a crop of Onions, however many we like, although we cant keep a conveyor belt of freshly grown Onions going.
The problem comes by way of the storage – can we store the Onions for all that time we are not harvesting (not just growing) them?
