The Q&A Archives: Fertilizing Mangoes

Question: I have found several articles regarding the fertilization of mangoes........all different! When should they be fertilized and what is the best type of fertilizer? Thanks!

Answer: Perhaps there's conflicting information because mangoes (Mangifera indica) are tropical plants, only marginally successful outdoors in the warmest winter areas of southern California. Because they are not widely grown, not a lot of research information is available. Mangoes need steady moisture but tolerate fairly poor, shallow soils. That to me indicates their need for fertilizer is relatively low. According to the California Rare Fruit Grower website, from year one to three apply N-P-K in the ratio of 15:15:15. From the fourth year on, add manganese to the N-P-K, at the rate of 12:12:17:2. Fertilize in the spring when new growth begins, applying at the rate listed on the label.
