Hello, I am new to gardening, besides a few papyrus, bamboo, ivy and some kind of vine that are nice enough to grow in my care! I am now trying my green thumb with roses. 3 weeks or so ago, I got my first rose bush, a rosa rugosa "Moje Hammarberg". And well, it is not doing bad but it is not doing well either... Some leaves are turning yellow, some are drying out and the roses do not bloom they kind of fade in bud. I also noticed some ants hanging out on the soil. I guess I should add, that since I do not have a garden the rose bush is in a planter (outside though). Your knowledge and advice would be much appreciated! Thank you in advance : )
