improving soil drainage without sand
"john zeiss" wrote
I have a lot of plants in Pots in a very small garden, and like to move
them around quite a bit according to whats in flower.
I like to have a free *draining* soil in the pots, but adding sand ends up
making them very heavy; especially the terracotta ones.
Is there anything I can use to 'add' to the soil to improve drainage,
that will not result in a increase in weight?
I use fine bark chips as used in Orchid composts.
