Welcome to The Helpful Gardener. I don't know what is available in India, but roses like a rich soil and need lots of water. If you can get or make compost and cover the soil with 2 inches of it, that will help your roses. If you can't get compost you could shred newspaper and add used coffee grounds. Mix it up and put that over the soil. Shredded leaves are also good to enruch the soil and help retain moisture.
