I have recently planted climbing roses at the back wall in my garden and have feed the soil around the roses with organic farmyard manure, can you please tell me how often I should do this and at what time of year.

Too much manure will make roses soft, leafy not flower as much and be more prone to disease. Us esome potash as well. Wood ashes contains about 5% potash, which is a useful amount and can be applied at about 100 to 200g per square metre.
