I need some advice regarding feeding roses, ive bought 'TopRose' by bayer, which suggests using it twice a year, over feeding will do more damage etc.
Is there anything else i can use regularly to boost flowering and plant growth. Ive read many times banana skins/whole bananas are a huge benifit, but how often do you use them ?
One of my customers has a huge garden with many rose plants, and their looking to buy another 8 standard roses in may for a wedding in aug, money doesnt seem to be a problem, i just want the plants to have the best start feeding regime possible.
Any advice would be fantastic.
