peach tree feeding

I have just planted one out in open ground. When it starts to grow I will probably use some general purpose fertiliser raked in. In your case it may be worth while using a tomato liquid feed at the start of the season then once it has flowered change to a general purpose liquid feed. I have a tree which has grown as a sport in the garden too. It grew some lovely white peaches last year so this year I am going to treat it to some feeding in an effort to produce a slightly better size of peach... although this may have nothing to do with the fruit size the tree will probably benefit
