Care
Sunlight
Choose a location in full sun to partial shade, protected from strong winds that can weaken the structure. Araucaria angustifolia appreciates generous light for harmonious development. In cold regions, grow it in a pot and bring it indoors during winter.
Watering
Keep the soil regularly moist without waterlogging, especially during the growing season. Reduce watering in winter. In pots, allow the soil to dry slightly between waterings. Use non-calcareous water if possible.
Soil and potting mix
Plant in a rich, well-drained, slightly acidic substrate (pH 5.5 to 6.5). A mixture of horticultural soil, peat, and perlite works well. Ensure good drainage to prevent root asphyxiation.
Fertilizer
Apply balanced fertilizer (similar NPK) in spring and summer, approximately every two months. Stop feeding in autumn-winter. Prefer a light formula: Araucaria is not a heavy feeder.
Pruning
No pruning is necessary; this tree naturally maintains its pyramidal shape. Remove only dead or diseased branches. Avoid cutting back the top, as this could affect the characteristic silhouette.
Diseases and pests
Watch for root rot (excessive moisture) and scale insects indoors. Check foliage regularly and intervene quickly at the first sign of infestation. Good air circulation prevents many problems.
Did you know?
The Paraná Pine is a living fossil: its genus Araucaria was already dominant in the Mesozoic era, coexisting with dinosaurs. In Brazil, this majestic tree long provided an edible nut (pinion) that was highly nutritious and traditionally consumed by the indigenous Guarani peoples, giving it significant historical cultural and economic importance.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
