Greenhouse

I have just built a greenhouse on an old patio whitch has a concrete floor can anyone advise me on the soil i.e whether to put it in in the spring or to leave it there all year
regards Otto

 

You could try grow bags, other wise drainage may be a problem

 

Hi Otto, I have a concrete floor in mine but when I was concreting I left a 'window' open for a peach to tree get it's feet out. If you needed to grow directly into the soil maybe a slab or two could be removed and the remaining soil improved. good luck

 

Sorry Otto, message rather than poll. Concrete floor will cause a problem with drainage, however a raised bed could work on top - but you would need to change the compost each year if you don't want to get a build up of greenhouse pests. Growbags and staging with plunge beds could be better.
