How do i grow miniature roses in the tropics?

I have baby masquerade miniature rose's in my window boxs which I purchased really cheaply from ebay I have planted them with a good quality soil,and mixed well roted manure through the soil and there growing really well. You can also plant them in the ground as a small hedge or shrub . Also a good idea to buy a lady bird house and place it near the rose bush as roses are prown to afids (green fly) lady birds love to eat the afids and it will control an infestation naturally. Also keep then well watered in full-partial sunlight. GOod luck and happy gardening.
