Because I'm convinced they don't 
I have been trying for months to grow blue roses, and they just won't grow! I've looked up lots of guides, so I know I have the correct combo of flowers - orange and purple to make hybrid red, and then 2 hybrid reds to make blue. I even have all my hybrid red roses on the beach so they won't be invaded by other flowers, and I water them with my golden watering can every day!
Nothing seems to be working! So, I was wondering if anyone has any tips on how they've achieved blue roses. Does fertilizer help? Flower placement? What have you found useful?

You are all very kind, thank you for offering! However, unfortunately, my wi-fi has never worked for my ACNL, and I tried it again just the other day, so I none of you can actually come over to my town :'( I am so appreciative of your offers, though! And I really would like to try breed one myself... however much pain this is going to take...
