Soil and situation may be the core of your apple problems

It’s a bumper year for apples, experts have told us, thanks to last year’s wet summer, this year’s late spring and the glorious summer of 2013 - but what if things haven’t gone so well?

While many gardeners will be crowing about the vast amount of apples they’ve picked from their groaning trees, a few will no doubt be wracking their brains about the lack of fruit, brown spots, maggots and general poor performance.

So, if you’re in the latter category, why might this have happened?

Well, the tree may be in too dry a spot, which will result in little growth. It may be too wet and the roots may drown each winter, especially in a heavy soil when the roots may be confined in a hole full of water after every rain. You also need to look at your soil, which may be too acid, too alkaline or just poor, with few nutrients. Exposure to sun also has a bearing. If the site is too shady then the plant can become stunted.

Royal Horticultural Society (RHS) fruit specialist Jim Arbury, explains: “Sometimes you will find trees originally planted in the sun may have become shaded by a conifer hedge or a building and this can affect fruiting. There have been situations where fruit may appear on one side of the tree which isn’t shaded and not on the other, which is.”

If the tree was container-planted when you bought it, did you make sure you teased out the roots before planting? If not, they may all be trapped in their original place where they are now strangling each other underground - a problem which is often presented by the plant bursting into life in spring before petering out and looking forlorn all summer. Others say their apple trees have grown well but simply haven’t flowered in spring. This is generally down to flowers being destroyed by frost, or trees being too young or too vigorous.

Arbury explained: “Often, when you’ve neglected a tree, then prune it very hard it will react by producing vigorous growth and may take time to crop again”

A give-away sign is when the branches are growing very strongly upwards, often with leaves that are dark green.

The expert went on: “The best thing to do with a neglected tree is to prune it over two to three years, to balance everything out, but it may take a few years to settle down again.”

Trees which look healthy but don’t fruit may be the victims of a serious water shortage at the start of the season, a problem which can easily be rectified.
