I have just ordered 4 collumer fruit trees for my patio from groupon. It was £15.99 for one apple, one pear, one cherry and one plumb. Just wondering if anyone had any success growing these ?im not expecting tons of fruit as they will only be small but Any tips would be greatly appreciated. I’m a novice gardener and only started to have any success with plants last year up until then I hadn’t realised the reason they were doing so poorly was because they needed more than just water
