Essex, United Kingdom

Used a plastic box L=111cm, W=45cm, D=54cm as a raised bed this year with some good results, garlic and shallots.I used my own compost = kitchen & garden waste seaweed horse manure etc. How often do you think I should change it or by how much. I also have a good supply of comfry & seaweed liquid fertilizer. Bob.
