Boron deficiency

A boron deficiency is recognisable by discolouration of the younger leaves. You’ll also see a rust-coloured deposit on the crop. New leaves seem to have their ends burned. A lack of boron also renders the crop fragile. Roots are also vulnerable to boron deficiency: their growth will lag behind.


How do you recognise a boron deficiency?

What is the (possible) cause?

How can you prevent it?

Boron deficiencies are rare. Under normal circumstances plants will not suffer from it. However, during intense stress or a growth spurt the plant is more susceptible to deficiencies. Use one of our base nutrients (like Alga Grow and Alga Bloom) to reduce the likelihood of a deficiency. Also keep abiotic factors in mind. These include temperature, light intensity, acidity, amount of moisture and wind strength.

How can you cure it?

Make sure the moisture level of your soil is in order. Lowering the pH value can also be a solution. To do so, rinse your system with clean, pH-controlled water. Older, damaged leaves may not recover.

What does boron do for the plant?

Boron is important for cell stretching and cell division. It plays a role in the water management of the plant and the transport of carbohydrates. Additionally, it stimulates the flowering. It also helps with the production of sugars.
