When and how to fertilise rose plants

   The best time to fertilise rose plants is when they are actively growing.   This means in spring and summer.   Because roses produce a lot of flowers fertilising is important to maintain good growth.  If you rose is lacking in vigour it probably requires a good fertilise.   Do not fertilise in winter, but a dose of around 50 grams around the root zone in spring and summer should be enough to maintain good growth and flowering.   It is best to use a specialist rose food which you can purchase from most nurseries.
