Be careful when planting trees in your garden

When designing a new garden, trees really should be the first feature to be considered, but great care must be taken as some have damaging root systems and should be avoided in small gardens, says Peter Dowdall.

Trees are natures carbon mops, filtering out many of the pollutants in our air and creating a fresher, more enjoyable environment.

In any garden much thought should be given to the choice of tree — and the smaller the garden the more important this becomes.
