A family of 6 could live happily off one courgette plant - something to remember!
Depends on how big your freezer is and if you want to store stuff or just eat what is in season!
next year i will allow for 50 sweetcorn - had 21 this year which was enough but didnt get to freeze any!
1 courgette plant, 1 patty pan plant, 3 buttercup squash plants, 1 marrow, maybe 4 other varieties of squashes.
8 rows of carrots, 5 rows of parsnips, lots of pots, 12 bulbs of garlic, 40 leeks, 3 rows swedes, 3 turnips, 1 swiss chard, 2 spinach, 3 spring onions, 10 onion rows, 20 asp crowns.
Just thinking aloud! LOL
