Rose Leaf Problems

Roses are not only colourful, fragrant and beautiful, they are also relatively easy to grow. They come in thousands of varieties and are really versatile having four basic types of growth: ground cover, bush, standard and climbing making them ideal for different parts of the garden.

To get the best out of roses some basic rules need to be followed. The most obvious of these is to buy healthy plants with disease resistance, plenty of roots and good stems. The ground should be well-prepared (not using fresh manure) and the roses should not be crowded. Proper planting in a suitable site (not waterlogged, too shaded or too exposed) will reduce the risk of wind-rock and weather damage. Once planted roses need to be fed with a specially bought feed (potash is essential).

On the whole roses are fairly hardy and can survive for years even if neglected. A poor regime of care however means fewer and poorer blooms and there is a risk 
of the plants running wild. Properly cared for roses will reward the gardener with wonderful blooms and a really absorbing hobby. As with all plants roses can fail for a variety of reasons. Learn to recognise the signs of trouble and you can take swift action.

Rose problems that show up in the leaves:

Lack of Phosphate

Symptoms: Small, dark green leaves with purple markings underneath. The leaves fall too early.
