Boron Deficiency in Plants

While macronutrients are obviously important for plants, the micronutrients are just as important.

Boron is one such micronutrient. It is required in very small amounts by plants. Boron is required for many different aspects of a plant, but how do you spot symptoms of boron deficiency?

Spotting Boron Deficiency Symptoms

As a micronutrient, boron is involved in cell growth. Therefore, when there is a deficiency in boron, it is expressed where cell growth occurs – the tips of root or shoots.

Generally, you will see stunting and distortion of the tip. This may manifest itself as brittle foliage, yellowing tips of leaves, or tip death.

Flowering and fruiting of plants are also drastically reduced. Certain plants like broccoli and cauliflower may develop hollow stems. However, be careful, as boron is not the only thing that can cause hollow stems. Sometimes, too much nitrogen or potassium can cause rapid growth, which can result in the same problem.

How to Improve Boron Deficiency

Boron is taken up by plants in neutral soils. If the soil’s pH is too acidic or too basic, it will become less available to the plant.

Other Macro and Micronutrients

As you may know, there are many other macronutrients and micronutrients that are important to proper plant growth. The macronutrients is split up into primary macronutrients and secondary macronutrients.

Learn more about each nutrient and how it effects plants so you can properly diagnose any deficiencies in your plants.

I also recommend checking out Earthpod Fertilizer capsules. While you can get the same results with other fertilizers if you’re very diligent with the right N-P-K ratios and other nutrients, these fertilizer capsules help take out a lot of the guess work. Furthermore, they utilize microbe technology to make sure all the macro and micro nutrients are delivered to your plants.
