Position – Nova Naartjies thrive in full sunlight, requiring 8-12 hours daily.
Size – Dwarf Nova naartjie trees can grow to about 2 – 3 mts tall, while the dwarf varieties will grow between 1.5 and 2 mts.
Soil type – These trees require soil with good drainage and do well in loamy and sandy soil types. They prefer a soil pH of between 5.5 and 6.5. Add ammonium sulfate to increase the soil acidity; to lower the acidity, add lime.
Mulch – Mulching around your tree makes it appealing and allows the soil to benefit from a constant supply of nutrients gathered by its slow decomposition process. Mulching will also keep the soil moist on warmer days and in winter.
Watering – Citrus trees need soil that is moist but not wet. The best method to water citrus trees is by watering deeply and infrequently. Water when the upper five cms of soil is dry. Test the soil by pressing a finger into the soil down to your second knuckle and see if the soil feels dry or moist.
Fertilizing – Yellowing leaves indicate that the tree needs fertiliser. Use a slow-release nitrogen-rich fertiliser, like Talborne Nourish.
Pruning – Prune your Nova naartjie tree periodically to keep it healthy and in shape. Cut back the branches that do not produce fruit. This allows the side branches to spread and grow into that space which will strengthen, allowing them to bear the weight of the fruit. Cut any branches growing towards the trunk to increase airflow between the branches.
