Durian Tree Nutrient Requirements
The nutrient requirement for a durian tree depends on the soil, climate, and irrigation practices. It’s important to make sure that the soil where the Durian tree would be planted is healthy so that it can grow properly. The durian tree needs Nitrogen, Phosphorus, and Potassium, they are called macronutrients because they are required in high quantities. In addition to the micronutrients, the durian tree needs calcium, magnesium, boron, sulfur, iron, and molybdenum. These are called the micronutrients, required in small quanities.
Nitrogen is needed in a high quantity at the early stage of growth; it is essential for the healthy growth of the root and foliage development. Similarly, Phosphorus is needed in appreciable quantity at the growing stage as it facilitates stem growth, giving the stem a sturdy appearance and strength for fruit bearing. Durian requires high Potassium fertilizer for fruit development at the later stage of growth. The micronutrients help in other biological activities such as photosynthesis, transportation, and the utilization of other nutrients by the durian tree.
It is very important to conduct a soil test before planting Durian to determine the fertility status of the soil. If your soil has low levels of nitrogen, phosphorus, and potassium, you will need to add these nutrients to the soil before planting the tree. When choosing a fertilizer for your durian tree, make sure that the fertilizer contains nitrogen, phosphorus, and potassium, alongside the micronutrients for proper and balanced nutrition. If it doesn’t, then it won’t be able to supply the required nutrients in the right quality and adequate quantity to sustain the durian trees.
Aside from the basic nutrients, good fertilizer for durian should also have other nutrients like calcium and magnesium, which help with root development. You may also want to add an organic mulch around your Durian tree if it has shallow roots or if there is heavy clay in your soil. This helps retain moisture in the soil and prevents weeds from growing around the base of your trees.
Other Fertilizers You Can Apply to the Durian Tree
Aside from the aforementioned recommended fertilizers being effective for the healthy growth of durian trees, I will not underestimate the importance and effectiveness of fertilizers like fish emulsion, animal manure, and compost on the growth of durian trees.
Fish emulsion, animal manure, and compost can serve as natural fertilizers for durian trees; they can be added to the soil (animal manure and compost) or used as foliar spray (fish emulsion). They are cheaper and slowly release nutrients for a relatively longer period than other fertilizer sources.
Best Time To Apply Fertilizer on Durian Trees
The onset of the rainy season is the best time to fertilize the durian tree. During this period, there is a low possibility of leaching of the nutrient, and maximum utilization of the nutrient by the tree can be achieved. Apply fertilizer during this period to aim for better bloom of the tree.
Granular fertilizers are applied using the placement method near the root zone of the tree. Liquid fertilizers are applied along with irrigation water using a method known as fertigation. Be sure to apply fertilizer using the recommended dose on the label of the fertilizer. It is there; ensure you read it.
Lastly, Durian trees are grown for their fruits and beautiful foliage. It is important that you use the right type of fertilizer for your durian tree. Different types of fertilizer have different nutrients and ratios of nutrients, so it’s important to get the right kind if you want your tree to grow well. Fortunately, there are many organic fertilizers available on the market today that will help keep your yard looking beautiful while promoting healthy growth for plants like durian trees.
