hi everyone,
 could anyone give me some advice on when to change the compost in my garden tubs.if at all? i have lots of salad leaves growing in them,would the compost be good for next year? or would i have to add to it in some way to replace the nutrients?
 i know that you would change your grow bags when planting toms etc.but next season i am going to try them in tubs with a mixture of soil compost&manure,could i keep on using the same mix year after year by just adding fresh manure&compost.or is it best to change the lot and start afresh each season.

Not sure what everyone does but I keep using the same tubs through out the season... just adding a bit of fish blood and bone in bitween plantings (usualy get to use every tub twice or maby three times... exect for tomatos)

Over ther winter on 'guarden days' i top them up with fresh compost from the heep and a bit more  fish blood and bone... but the next year I don't plant the same things in the same tubs.... that way I get a bit of a rotation.

After 3 years I tend to empt it ll out and start again.

Seems tobe working for me

P.S. One tip i use in my tubs if im growng somthing with shallow roots is a scrucned up old compost bag in the bottom to fill up the space

It also depends of course on what you are going to do with the soil that's in the tubs when you empty them and how many you have. This could be a major consideration.
