About netting...thing is...birds are 'funny things'..in general I don't tend to net anything and that is risky because you just don't know what might appeal for them from one year to other. One year, given a chance they will rip something apart and eat everything of that sort food..and following year they will take liking for something else and ignore the previously hammered typesOh thanks so much for all the info about your plots. I have 140m2 (town planner, therefore I use metric). I am really interested in the blueberries as I said earlier. They are great and quite low carb. Nice to have a bit of fruit to nibble on and they appear to have virtually magical properties.
I don't feel brave enough yet to try the brassicas, I am not good at the netting and covering, but spinach is on my list of things to do along with beans, squashes, courgettes, onions, leeks and suchlike. I think I will reserve a spot for berries. Do blueberries need netting?
Dont have enough room for a polytunnel or a shed, so am trying to blag some room in a friend's greenhouse. I will keep everyone posted.


So as for answer for you question....yes, you quite likely need to net the blueberries but only once you actually have berries on them and they are just about to start to change colour.
As for brassicas...you might get away with those...but if they start showing signs of being nibbled..net them and once they get little taller and tougher, birds usually leave them alone then and you can take the netting off.
