Grapes are one of the most varied of all fruits; they come in a host of different colours, flavours and sizes. They can be grown in almost every part of the world, treated and pruned by all sorts of methods and used in a multiplicity of ways. Although they are easy in pots under cover these do not give the yields of open ground plants. Unfortunately here in the UK we are on the very margin of successful outdoor cultivation. The changeable nature of the infamous British weather makes grapes a difficult crop. But modern varieties are making it much less of a gamble.
