we have a small, shady garden. how can I encourage our azaleas to grow up rather than out?
we are having trouble with our azelias. rhodedendrons and skimmia. yellowing of the leaves and poor growth . our has a acid tendancy but still these plants are reluctant to perform !. the sun comes round the back onto the flowe bed at about 4pm so is not at its strongest. any ideas please ....julie
