ðą How to Care for Pineapple Guava to Prevent Phyllosticta Leaf Spot?
ð§ How to Water
Water regularly during spring and summer, allowing the surface layer of the soil to dry out slightly between waterings: the feijoa is sensitive to waterlogging, which is the main cause of root rot. Once established, it tolerates drought well; in pots, it requires more frequent watering than in the ground.
âïļ Lighting
Prefers full sun exposure, with at least 6-8 hours of direct light per day to ensure abundant flowering and fruiting; it also tolerates light partial shade, but with lower fruit production.
ðŠī Ideal Soil
Prefers sandy to loamy, well-drained soil, rich in organic matter and with a slightly acidic to sub-acidic pH. It also adapts to poor or clayey soils as long as they are well-drained; in the case of heavy soil, it is useful to plant on a mound to promote drainage.
