When you plant a rose tree, take a patch of grass and place it face downwards at the bottom of the prepared hole. Spread the roots of the rose tree out on it and plant in the usual way. This seems to make the rose tree grow much healthier.
Fertilize your roses by burying chopped banana skins in the rose beds.
