Here is my onion patch covered with netting. I used the stones i dug out of my bean trench to hold it down.

I've gorn expensive and have a collection of what look like very light weight metal tent pegs for a play tent. They work a treat and can be used again and again. They don't flatten the soil like bricks and other such items.

i use tent pegs too!

I use plastic netting pegs (secret is not to push them through the netting but use the right-angled "head" to hold the netting down from the outside edge of it.)

Works well, and the netting is easy to free (and re-secure) without damage, although I can imagine breaking a few pegs in soil less yielding than mine - metal tent pegs would probably last longer on heavy soils.

I go against what the books say and completed bury the bulb, (only just).

Don't get a problem with birds and it saves another bit of netting.

I tend to bury mine too, but unfortunately the pigeons down here like eating the green tops as well, so the netting had to stay.
Hey ho.....

I use a homemade cloche which is covered in netting stapled to the wood frame base and supported by alkathene piping.
