What to do with used compost
Each year I grow a variety of plants in containers, some free standing and some fixed to the walls. This year for the first time, I am growing Potatoes in bags and Runner Beans in pots.
The flowers are always very pretty and so far the vegetables look ok.
In the past I have always scattered and dug in a bit the compost from containers at the end of the season. I thought this was a good idea given that the soil here is clay and also a bit scarce in places.
Recently though I read that compost should be disposed of because it will have lost all of its value over the summertime.
This is just bags of multi-purpose compost from Sainsburys usually and certainly nothing hugely expensive.
Is it ok to still put it on the flower-beds or is that not a wise thing to do?
