Trying again for suggestions for pots on my roof
Pots are 1m tall 40cm x 40cm, black and very light weight. They will not blow of the roof as they will be bolted down. they will not be heavy when filled as the lower 0.5 to 0.7 will be filled with polystyrene. The soil will be 50x 50 with vermiculite. They will have a drip system attached to them. All I want is suggestions as to what to put in the 5 of them. I want something tallish, evergreen and fairly low maintenance as I only intend to walk on the roof twice a year and yes decking is being placed around the roof as the roof is put on the building so that I can walk around it without damaging the roof. Anyone got a balcony? what do you grow on it?
