did it crop well last year? sometimes they just have a 'bad' year and have a rest.

Last year was a really bad year for all our apple trees, old established ones and any newly planted. The Greengages had about three fruit on it, I think they were resting, this year they are packed, just waiting for the June drop.

Many Cox cultivars are in fact triploid; they need two other varieties of apple to pollinate them. Have a look at their pollination group at reliable fruit growers. Having said, Cox are not the easiest variety to grow as they are fussy on their location and soil conditions.

Interesting Jimmy. I didn't know that. Now I know what not to grow. I was just wondering how old the trees are. Some trees need to be 6 or 7 years old before they produce and the first couple crops are a little wonky doodle. It may need couple more years to 'get its game on'.

Thanks for your replies. Last year there was a lot of fruit on the James Grieve but they all dropped off. There was also some ‘wonky doodle’ (love that phrase) on the Cox but the same thing happened.
I don’t know how old the trees are but they are about 5ft in height if that helps. They are dwarf varieties.
Maybe, as an apple lover, I’m just impatient. Thanks again.

Years ago my Mum had a Cox and a James Grieve. The Cox never did anything much. There are lots of suggestions on line for other pollinators for Cox, if you have room for another one. (Doesn't help much of the Cox doesn't flower though...)
