Cara Cara oranges, botanically classified as Citrus sinensis, are a natural hybrid that belongs to the Rutaceae or citrus family. Also known as the Pink navel and Red navel, Cara Cara oranges are believed to be a cross between the Brazilian Bahia and the Washington navel orange and were discovered as a mutation on a Washington navel orange tree in Venezuela. Favoured for their berry-like flavour and low acidity, Cara Cara oranges have recently increased in popularity as specialty fruits are being highlighted on social media, bringing awareness to the unusual varieties.
They prefer full sun but in the warm areas of the country will handle some shade.
Need water regularly especially during summer. Water newly planted trees once or twice per week deeply.
Well-draining slightly acidic soils. Use high quality organic mix
Citrus are heavy nutrient feeders, use a high nitrogen NPK fertiliser. Apply 200g at the drip line (2/3 in spring and 1/3 in summer) increasing this by 200g per year until you are applying 2kg. Apply manure in the autumn spread under the tree with mulch.
Not very wind tolerant but reasonably tolerant to salty marine conditions.
Need protection from frost.
1-3 years after planting for grafted plant
Citrus are not trained to any particular shape, some varieties do not need any shaping at all. Prune to shape if necessary and any dead or diseased branches. They will tolerate heavy cutting back. Also remove any sucker growth.
