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 varieties of liquid fertilisers, their usage, and reasons why they’re useful for maintaining thriving plants and lawns.

Types of Liquid Fertilisers

Natural liquid feeds are produced from sources like decomposed plant material and animal manure.
They offer vital nutrients and beneficial bacteria that enhance soil structure and water-holding capacity, making them ideal for eco-conscious gardeners.

Chemical-based liquid feeds, on the other hand, offer concentrated nutrients and can lead to faster growth.
They are effective when quick results are needed, but must be used with care to prevent over-fertilisation.

Benefits of Using Liquid Fertilisers

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

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

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

Guidelines for Applying Liquid Fertiliser

The optimal time to apply liquid fertiliser is during the plant’s growth period, typically in the early growing season.
Refrain from applying during hot spells or dormancy, as it can stress the plants.

• Spraying: Suitable for fast absorption via leaves and for treating specific deficiencies.


• Base application: Direct application to the root zone for effective nutrient uptake.


• Soil drenching: Promotes deep root development and soil penetration.

Be sure to follow the manufacturer’s recommended dilution rates.
Excessive use can lead to plant burn, nutrient runoff, and stress 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 essential for flowering and fruiting.

Soil acidity and texture should also influence your selection.
Sandy soils may need more frequent feeding due to leaching, while low pH conditions here may require neutral or alkaline formulations.

If you’re interested in sustainability, an organic product is often the most appropriate option, especially for long-term 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 prevent evaporation and reduce scorching.

Can it be used on houseplants?

Absolutely. Dilute the solution to avoid overfeeding indoor plants.

Is it safe for pets?

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

Wrapping Up

Liquid fertilisers are a reliable option for those seeking vigorous, well-fed plants without complicating their care routine.
Whether you're maintaining a garden, lawn or indoor space, liquid feeding provides consistent results when used correctly.
