Mango (Mangifera indica), native to tropical regions of Burma and eastern India, is an attractive spreading tree for landscaping and shade in addition to fruit production. Mangoes usually bloom before flowering, not before blooming Temperatures below 30 degrees Fahrenheit cause severe damage to mango trees, while temperatures above 40 degrees F kill the flowers and fruits of most species. Some mango species grow in United States Department of Agriculture plant hardiness zone 10.
Best Fertilizer For Mango Plants
Fertilizer numbers show the ratio by weight of the main plant nutrients nitrogen (N), phosphorus (P) and potassium (K). This ratio is expressed by a number on the package, such as 10-10-10, which is 10 percent of those three nutrients. Slow-release fertilizers are polymer or sulfur-coated granules that take 8 to 12 weeks to dissolve in the soil. Soluble quick-release fertilizers, generally less expensive than slow-release fertilizers, enter the soil immediately with irrigation. A complete fertilizer is a fertilizer that contains all N, P and K Chelated iron and other minerals mean they are more absorbed by mango roots.
Timing Is Everything
University of Hawaii horticulturists recommend first-year mango trees receive 1 to 2 pounds of 10-20-20 fertilizer divided into three or four pre-applications. In their second and third year, they should be fed 1 1/2 to 3 pounds of a 10-20-20 fertilizer. Fertilizer is spread directly below the leaf drop line and watered into the soil University of Florida horticulturists say any complete fertilizer containing 6 to 10 percent nitrogen, 6 to 10 percent phosphorus and 4 to 6 percent magnesium is suitable for young mango trees. Avoid over-fertilizing young plants
University of Hawaii horticulturists recommend 1 pound of complete, slow-release fertilizer annually for every inch of stem diameter 4 to 5 feet above the ground. Half of these fertilizers are applied before flowering, not during flowering and the rest after mango harvest In general, fertilizers should contain 9 to 15 percent potassium and reduce phosphorus to 2 to 4 percent to support trees. Common fertilizer combinations that are satisfactory for mango trees include magnesium showing 6-6-6 and 8-3-9-2, 2. To encourage flowering and mango yield, supplemental quick-release fertilizers containing nitrogen are applied to mango trees just before flowering.
The California Rare Fruit Growers Association (CFRG) states that healthy mango trees require chelated iron and other micronutrients. You can have your soil tested by a lab to see if there is a mineral deficiency, but results will take 1 to 4 weeks. A less expensive and acceptable option is to purchase a soil test kit at garden supply centers CFRG states that fertilizing mango trees is similar to fertilizing citrus trees and that mango trees should not be fertilized after mid-summer. Mango trees planted in sandy soil require more fertilizer than trees planted in clay or peat

How To Apply Organic Fertilizer On Mango Trees
16 nutrients are required for plant growth They are divided into macronutrients and micronutrients Micronutrients are needed in greater amounts than micronutrients, but all 16 elements are needed for proper plant growth. Macronutrients are nitrogen, phosphorus, potassium, magnesium, calcium, and sulfur. Micronutrients are iron, boron, manganese, zinc, chlorine, copper and molybdenum. Carbon, hydrogen and oxygen are also needed, but these are easily supplied by nature
If the pH is high, they cannot move through the soil In South Florida, we have a pH of 7.8 to 8.8, which binds micronutrients. If your granular fertilizer has zinc and boron in it, your plants will lack these nutrients because they will be trapped in our high pH soil. Because of our limestone-based soil, we apply micronutrients via foliar spray rather than soil. Iron, a micronutrient that helps keep a plant green, is usually applied as a separate liquid from a foliar spray. The type of iron being applied should be chewed and mixed with water and poured over the roots
Micronutrients should be applied to plants during the rainy season and not during the dry season as they are not properly absorbed. Micro can be applied two or three times during the rainy season depending on the needs of your plants When you apply microfoliar, you should spray the top and bottom of the plant leaves thoroughly until the product is absorbed by the plant. Iron drench should be applied when the soil is moist and placed near the drip line of the tree The drop line is the outer part of the tree where the wall ends
These are usually applied in granular form and dispensed as your plant needs All fertilizer bags must have nitrogen, phosphorus and potassium rations on the label. Nitrogen helps a tree’s leaves grow, phosphorus is responsible for plant health, and potassium helps flower and fruit develop. A good N-P-K ratio for tropical fruit trees is 8-3-9 But mango and litchi trees do not do well with high amounts of nitrogen, so fertilizers with a high proportion of potassium and a low proportion of nitrogen work well. Be aware of timing: Applying nitrogen before trees flower can cause leaf growth instead of flowers and disrupt the fruit cycle.
How To Make Mango Tree Bear Fruit Faster
Granular fertilizers should be applied three to four times a year, but not before the plants bloom Start your granular applications in May and keep them every month until the dry season When applying granular fertilizer, avoid compaction of the fertilizer As you apply it, spread it along the drop line and then If you go around the tree and spread the fertilizer at the top, you should be giving the tree the right amount of fertilizer
How do you know what to apply to your plants? Micronutrient deficiency usually occurs in new leaves, while macronutrient deficiency occurs in older leaves. Treating personal deficiencies is generally not a good idea Micronutrients are usually the primary Applying them separately can throw off how nutrients are absorbed Instead, try micro or macro treatments
Keeping your plants on a regular fertilizer program will keep them healthy and less vulnerable to pests and disease. Don’t forget about mulching and composting This helps reduce the need for large amounts of fertilizer application
The most common mistake is to apply granular fertilizer near the stem This is worse for feeder roots that are close to the drip line Large roots near the trunk that store water and anchor the tree Instead, spread the fertilizer evenly over a large area under the tree An 8-3-9 fertilizer works best for most fruit trees and a palm variety is best for most ornamentals.

Mango trees (Mangifera indica) are easy to grow organically because they can get the nutrients they need in abundance from organic matter. They are drought-tolerant trees that produce abundant yields of sweet, juicy fruits that are colored red, yellow, and gold rather than green. They grow in United States Department of Agriculture plant hardiness zones 10b through 11.
Traditional mango cultivars are round evergreen trees up to 45 feet tall and wide, but newer cultivars like “Angie” and “Jean Ellen” are more compact and disease-resistant than their older counterparts, making them ideal for backyard production. . Mango trees require full sun but are not fussy about soil types They need regular water when young, but very little once established
The NPK ratio on the fertilizer container lists the percentages of nitrogen, phosphorus, and potassium in that order. Mango trees need more nitrogen when they are young, but less after they begin to bear fruit In that case, they need more phosphorus and potassium, which promotes flowering and fruiting. Use a commercial organic fertilizer with a high percentage of potassium
