🌱 How to Care for Mamey Sapote to Prevent Manganese Deficiency?

💧 How to Water

New tree: water every other day for the first 4 to 6 weeks unless it rains. Mature tree: water once or twice a week in dry weather, especially during flowering and while the fruit sets. Cut back in winter. Skip timer-run sprinklers, which can lead to root rot.

☀️ Lighting

Plant it in full sun, with at least 8 hours a day. Shield young trees from cold wind, which damages the big leaves.

🪴 Ideal Soil

It grows in clay, limestone or sandy soil as long as water drains away. Deep soil with a pH of 6.0 to 7.0 suits it best. If water sits or floods where you live, plant it on a mound. On limestone soil, leaves may yellow from a lack of zinc or manganese.
