Overview of Liquid Fertiliser Applications

Liquid fertilisers have become a popular choice in horticulture and grounds maintenance, due to their straightforward application and fast nutrient absorption.
This article examines the types of liquid fertilisers, how they are applied, and reasons why they’re useful for maintaining healthy plants and lawns.

Varieties of Liquid Fertilisers

Organic liquid fertilisers come from sources like compost and manure-based materials.
They contain vital nutrients and beneficial bacteria that support soil condition and moisture retention, making them well-suited for environmentally aware gardeners.

Synthetic fertilisers, by contrast, deliver concentrated nutrients and often encourage accelerated growth.
They are useful when immediate results are needed, but must be used with care to avoid over-fertilisation.

Advantages of Using Liquid Fertilisers

One key advantage is the efficiency at which nutrients are absorbed by plants.
Since the nutrients are already in liquid form, plants can utilise them quickly, resulting in faster visible growth.

Unlike granular alternatives, liquid fertilisers allow for more precise application, ensuring that nutrients are spread consistently, minimising waste and targeting specific plant areas.

They are also appropriate for mature plants or soils suffering from restricted nutrient website uptake, where soil disruption is undesirable.

Guidelines for Applying Liquid Fertiliser

The optimal time to apply liquid fertiliser is during the plant’s active phase, typically in the early growing season.
Avoid applying liquid fertiliser applications during hot spells or dormancy, as it can damage the plants.

• Foliar application: Ideal for fast absorption via leaves and for treating specific deficiencies.


• Root feeding: Targeted application to the root zone for effective nutrient uptake.


• Deep watering: Encourages deep root development and soil penetration.

Always adhere to the manufacturer’s specified dilution rates.
Over-application can lead to plant burn, pollution, and harm to plants.

Things to Keep in Mind When Choosing a Liquid Fertiliser

Nutrient ratios are important for matching fertiliser to plant needs.
For instance, high nitrogen supports leafy growth, while phosphorus is beneficial for flowering and fruiting.

Soil acidity and texture should also guide your selection.
Sandy soils may need more frequent feeding due to leaching, while acidic soils may benefit from neutral or alkaline formulations.

If you’re interested in sustainability, an organic product is often the most appropriate option, especially for eco-friendly soil health.

Frequently Asked Questions

How often should liquid fertiliser be applied?

Typically every 2–4 weeks, depending on plant type and growth stage. Check the plant's specific needs.

Is it suitable for lawns?

Yes, it promotes uniform growth and healthy green coverage.

When is the best time of day to apply it?

Early morning or late afternoon to avoid evaporation and reduce scorching.

Can it be used on houseplants?

Absolutely. Dilute the solution to avoid overfeeding indoor plants.

Is it safe for pets?

here

Generally safe once dry. Keep pets away until treated areas have dried fully.

Wrapping Up
