Lime Sublime Dwarf

Ava starts with ...
Hi i. Bought this plant round jan 2015. It was 15 cmwhen i bought and single stem. I potted it in 40litre pot with premium potting mix. Have placed it in full sun area. The plant is growing well but leaves have curled a bit in some of the part. I prune it at times. The plant is now around 70cm and have grown several branches. I could see lot of small flower but flowers have dropped and can see small buds. I was hoping it to be tiny limes but couldn't see them growing..been a week. How long will it take to grow the fruit. How do i have to cure the leaves and how often do i have to water the plant? Please help
