Hesi Hesilicio – silicon booster for strong, resilient plants

Plants need more than just water and nutrients – they also need to be strong enough to withstand drought, pests and temperature fluctuations.

With Hesi Hesilicio, Hesi is expanding its range with a powerful silicon booster that strengthens cell structure and sustainably improves plant resistance.

This liquid plant fertiliser with a high silicon content provides an essential mineral that is crucial for plant growth, stability and health – both in the root zone and in the leaf tissue.

What is Hesi Hesilicio?

Silicon is a natural building block of plant structure and plays a central role in the formation of stable cell walls, the absorption of nutrients and the defence against environmental stress.

Since pure silicon in its solid form cannot be absorbed by plants, it must be present in a soluble form that is available to plants.

Hesi Hesilicio contains 3% orthosilicic acid in colloidal form – the most effective form of silicon for plants. This allows it to be absorbed through both the roots and the leaves.

The result:

• Stronger plant structures
• Improved resistance to drought, diseases and pests
• Optimised absorption of nutrients and trace elements

Advantages at a glance

• Stronger cell walls in leaves, stems and roots
• Higher resistance to drought stress, pests and infections
• Better nutrient uptake through optimised cell structure
• Increased vitality and stability of the entire plant
• 3% orthosilicic acid – quickly available to plants and highly effective
• Liquid, colloidal formulation – easy to dose and apply

Properties

• 3% orthosilicic acid (SiO₂ / SiO₃) in colloidal form
• Stable silicon particles – evenly distributed in the solution
• High bioavailability – absorption via roots and leaves
• Liquid formulation – easy to dose and combine
• Supports cell wall formation, nutrient efficiency and resistance

Application & dosage

Dosage

• 0.5 ml per 1 litre of water
• Less is not a problem – but do not exceed this amount!
• It is better to use a small dose regularly than too much at once.

Application

• Add to watering water once a week
• Can be applied via watering water or as a foliar spray
• Can be combined with all Hesi fertilisers and boosters
