what type of grit should i use to help drainage in pots.

On plant healthy root groweth



I use horticultural grit in the compost or vermiculite depending on what i have to hand. for those that dont like wet 'bttoms' I often use a 1/2" layer of washed sand to sit the bulbs on.
as crocks in the bottom of pots i use broken terracotta pots or pebbles from the beach.

welcome to GOY too. :)

We don't use crocks in the bottom of the pots at all. The compost will have about one-third part 6mm grit in the mixture to aid drainage. (6mm because that is what is locally available, 4mm might be better)

George, if you use sand make sure it is the coarse one and not fine builders sand.
