Growing my own

Hi

I read on the internet that it is possible to convert flat roofs into 'green roofs' by waterproofing and insulating the ashphalt, laying drainage and substrate, and planting herbs and vegetables over it.

Apparently planning permission is not required according to "thegreenroofcentre" web site. How then does one enclose the flat roof space - that must need PP? Access to it must also need PP.

Info is scarce so I'd love to hear from anyone who has some knowledge or experience of installing a 'green roof' on their flat roof.

Thanks!

ps - I live in a flat [not a house], hence no proper garden ... but my flat itself has got a flat roof.

Ummm...soil is heavy. Wet soil is VERY heavy. You're not thinking of growing potatoes, are you?

:eek:
apparently its quite common in germany [not growing potatoes on roofs, but the growing plants on roof substrate idea]

but was thinking more of coriander, tomatoes, leafy veg...

guess its easier [and cheaper] to use plant pots

There are lightweight alternatives to planting the whole roof, like grow bags, which use fairly small amounts of soil to sustain large amounts of plant.
