Guava Plant Fertilizer: Top 4 Essential Nutrients and How to Apply Them

Guava trees are a popular choice for home gardeners due to their delicious fruit and relatively easy care. However, like all plants, they need the right nutrients to thrive. The four essential nutrients for guava trees are nitrogen, phosphorus, potassium, and calcium.

1. Nitrogen

Nitrogen is essential for plant growth and development. It helps to produce chlorophyll, the green pigment that allows plants to photosynthesize. Nitrogen also helps to produce proteins, enzymes, and other essential plant compounds.

Guava trees need about 1 pound of nitrogen per tree per year. This can be applied in the form of a fertilizer that is high in nitrogen, such as ammonium nitrate or urea.

2. Phosphorus

Phosphorus is essential for root growth and development. It also helps to produce flowers and fruits.

Guava trees need about 0.5 pounds of phosphorus per tree per year. This can be applied in the form of a fertilizer that is high in phosphorus, such as triple superphosphate or diammonium phosphate.

3. Potassium

Potassium is essential for water uptake and transport. It also helps to produce starch and sugars.

Guava trees need about 1 pound of potassium per tree per year. This can be applied in the form of a fertilizer that is high in potassium, such as muriate of potash or potassium sulfate.

4. Calcium

Calcium is essential for cell wall development and strength. It also helps to prevent blossom-end rot.

Guava trees need about 0.5 pounds of calcium per tree per year. This can be applied in the form of a fertilizer that is high in calcium, such as gypsum or lime.

How to Apply Guava Plant Fertilizer

The best time to apply guava plant fertilizer is in the spring, before new growth begins. However, you can also fertilize your guava trees in the fall, after they have finished fruiting.

To apply fertilizer, simply broadcast it around the base of the tree and water it in well. Be sure to follow the directions on the fertilizer package.

Troubleshooting Guava Plant Fertilizer Problems

If your guava trees are not growing well, it may be due to a fertilizer problem. Here are some common signs of fertilizer problems:

• Yellow leaves: This can be a sign of nitrogen deficiency.
• Stunted growth: This can be a sign of phosphorus deficiency.
• Poor fruit production: This can be a sign of potassium deficiency.
• Blossom-end rot: This can be a sign of calcium deficiency.

If you think your guava trees may be suffering from a fertilizer problem, you should have your soil tested. A soil test will tell you what nutrients your soil is lacking and how much fertilizer you need to apply.
