Help - why are my large oranges not turning orange, they are slightly lime/yellow

Hi Jenny

Thanks for your question. Your oranges just need a bit more time on the tree to develop the orange colour. They go from a green colour through yellow to an orange colour. They eventually go a redy orange colour but the fruit is over ripe by this time. Just keep them well watered and fed with some Yates Thrive Flower & Fruit Soluble Plant Food so you get nice juicy fruit. Steve
