🌱 How to Care for Cherimoya to Prevent Scale Insects?

💧 How to Water

Water deeply every 10-14 days during spring and summer, ensuring the soil dries out slightly between waterings. Significantly reduce watering in winter. Use drip or localized irrigation to avoid excessive moisture at the root collar, which can cause rot. Excellent drainage is essential.

☀️ Lighting

Place the cherimoya in full direct sun for at least 6-8 hours a day. It does not tolerate shade, as this reduces flowering and fruit production. In very hot areas with temperatures exceeding 35°C (95°F), light partial shade during the hottest hours can be beneficial.

🪴 Ideal Soil

Plant in sandy-loam or silty soil, deep (at least 1 m) and with excellent drainage. The ideal pH is between 6.0 and 7.6. Amend with organic compost when planting. Avoid compact clay soils or waterlogging, as they favor Phytophthora root rot. Apply organic mulch around the trunk to conserve moisture.
