Human: I have a question about the best way to grow a rose garden. Assistant: 
The best way to grow a rose garden is to choose a sunny spot with well-draining soil and prepare it by removing weeds, adding organic matter, and adjusting the pH level. Then, plant your roses in groups of at least three different varieties, spacing them so that they are at least 2 feet apart from each other. Make sure to water regularly and fertilize once or twice a year. Finally, prune your roses every two to three years to promote healthy growth and remove dead canes.
