Our compost is mostly organic and made up of composted bark, topsoil, sand and pelleted chicken manure. This seems to be working well so far. Given the conditions are right and they are initially kept moist and weed free, once established they should look after themselves for years to come.
Pollination can sometimes be a problem, although most are self-fertile they will generally all fruit better if more than one of the same species are grown together.
Please be aware that the sizes given in the plant descriptions are only a rough guide.
Plant height and width depends as much on the conditions and climate they are growing in so can only be approximated.
