Pots question

[DaveC]

I recently bought 3 galvanized metal square pots from B&Q half price and they are of 3 different sizes. My question is this....Should I line the pots with anything before planting them up or will they be ok? Any advice will be greatly appreciated

Thanks

have they got drainage holes? (they need some)

Don't bother lining them!

They have one hole about the size of a 10p, would that be enough? or should i make a few more?
