Over the last few months our local council have changed our bins for recycling,from the square green plastic boxes to wheely bins.This is good for us as I have now collected all the neglected/unwanted green boxes put a few extra holes in the bottom given them a good pressure wash and voila planters for free idea for strawberry's and lots of other uses well chuffed.
Sadly I wonder how many are just dumped in a skip!

I know the kind of box you mean, we had the same kind down south. In a similar vein, fish boxes...



...are easily obtained here. We have used them a number of times to grow salad leaves. They're great for successional sowings of cut and come again type leaves. I'd imagine they'd be good for annual herbs too.

I've grown spuds in recycling boxes as well

So far I have mint in 1 and strawbs in 4 and another few ready and waiting in the wings.
I haven't thought about spuds but will go for that for next Christmas spuds!

I grow carrots in 'the locals' discarded recycling boxes.

My spring onions did well in those sort of boxes last year too.  To start them off I covered the box with an old bit of double glazing to make a hot box!!!

I did spuds on my rooftop garden last season - the boxes were great.. A real neat way of planting in confined spaces.
