Pak Choi and Spring Onion Crop Protection

Hi

I'm growing the above. Have sowed and looking to plant out. What's best protection for these.

Looking to harvest in March 21.

I have environmesh and also the semi-circle looking net which seems to look ok.

Any ideas?

Thanks in advance

 

Spring onions really need no protection, Pack Choi is not something I've ever grown so maybe someone else will come along to help with that one.
My thoughts are slugs and pigeons are most likely to be the problem.

 

Thanks - will be growing for first time.

Have been using beer cans for the slugs for other veg which is working well.

the garden tunnel netting I have will hopefully protect against the birds
