During cool, moist periods that are prevalent in autumn, rose bushes can be subjected to leaf drop due to a fungus infection known as Black Spot.

Many modern varieties have a genetic resistance to such infection, however our favourite rose type, the hybrid tea’s can be defoliated more easily.

Although it can be avoided by timeous preventative and regular spraying with a suitable fungicide such as CHRONOS, which is contained in our cocktail, or ROSE PROTECTOR, during extended wet weather conditions such leaf drop will still occur.

A rose bush with only a few leaves on top is not only unsightly in a garden, it will also stop producing quality blooms.

By grooming appropriately, namely cutting away most leafless side twigs and stems, a concentrated, strong upward sap flow to the remaining higher up leaves is created.

It is not a difficult concept. You simply cut away side stems that don’t have any leaves on, remove stems that carry spent blooms and generally just envisage creating a smooth and fast route to the top leaves and back to the roots.

Photosynthesis in the existing leaves is increased, which in turn facilitates the flow of sugars and carbohydrates to the roots.

Dormant eyes on the stems are activated on the way down. The activated eyes quickly sprout leaves and then produce nice stems with pickable blooms.

Stimulating new shoots is the aim of the entire exercise.

It is advisable to adhere to a spraying program from now on. Heavy dew on the new leaves in the early mornings is bound to renew infection. Keeping the leaves healthy can promote flowering right into the start of winter.

An application of Vigorosa fertiliser will encourage extra strong, new growth.

Thank you for watching and enjoy the roses!
