rosa rugosa rubra…..I planted over 300 as a hedge next to our drive two years ago. This summer I noticed a few that had been so aggressive that they had tried to burrow under the kerb (1.5metres away) and then tried to surface via the tarmac base coat. What sould I do??? I dont mant to take them out as they are a valuable tool for my bees and birds and their fragrance far outweighs their dark side!!!!
