Many gardeners, whether beginners or experienced, often struggle with plants that grow slowly, produce fewer flowers, or fail to thrive despite their best efforts. Poor soil health, lack of essential nutrients, and weak root systems are common problems that limit plant growth and productivity.
In this article, we’ll explore:
Seasol PowerFeed is a liquid fertiliser that offers dual-action benefits: it feeds plants directly while also conditioning the soil. The product is formulated to boost plant growth and vigour, stimulate flowering and fruiting, and improve soil structure. It contains active liquid composts that enhance soil microbial activity, which in turn helps break down organic matter and release nutrients to plants.
Seasol PowerFeed contains a blend of nutrients essential for plant health:
Nitrogen (N): 12.0%
Phosphorus (P): 1.4%
Potassium (K): 7.0%
These nutrients are complemented by fish extract and liquid humus, providing a balanced feed that supports both above-ground growth and root development. The inclusion of liquid composts also stimulates beneficial soil microbes, improving soil structure and nutrient availability.
The balanced nutrient profile of Seasol PowerFeed supports healthy plant development, leading to lush foliage and robust stems.
The fish extract and liquid humus in Seasol PowerFeed encourage strong root systems and abundant flowering, contributing to overall plant vitality.
Regular application of Seasol PowerFeed can help plants withstand environmental stresses, making them more resilient to adverse conditions.
The liquid composts in Seasol PowerFeed enhance soil health by promoting the growth of beneficial microbes, which break down organic matter and release nutrients to plants.
Seasol PowerFeed is versatile and can be applied in various ways to suit different gardening needs:
Lawns: Mix 10mL in 1L of water. Apply every 2-4 weeks over 2-4m².
Trees: Mix 10mL in 1L of water. Apply every 2 weeks over 2-4m².
Garden Plants: Mix 10mL in 1L of water. Apply every 1-2 weeks over 2-4m².
Vegetables & Herbs: Mix 6mL in 1L (or 50mL in 9L) of water. Apply every 1-2 weeks over 2-4m².
New Plantings: Mix 4mL in 1L (or 30mL in 9L) of water. Apply at planting and again after 2 weeks.
Indoor Plants & Ferns: Mix 3mL in 1L (or 20mL in 9L) of water for foliar sprays. Apply every 1-2 weeks.
Foliar Sprays: For actively growing plants to improve iron nutrition and stress tolerance, use 5-10L per hectare.
Boom Sprayers & Under-Tree Sprinklers: Determine product quantity based on tank coverage. Use 5-10L per hectare.
Drip or Micro-Irrigation Systems: Higher rates for sandy soils. Use 5-10L per hectare.
Overhead Sprinklers: Lighter soils: Higher rate; Heavy soils: Lower rate. Use 1L to 5L per mm of irrigation or 10L per hectare for 10mm irrigation.
Small Volume Applications: Mix 3-5mL per litre for hand sprayers and knapsacks. Use 20-50mL per 9L watering can.
Always mix as directed before application and refer to the product label for complete usage, safety, and storage guidelines.
While both Seasol and Seasol PowerFeed are products of the same company, they serve different purposes in plant care:
Seasol: Primarily a seaweed-based tonic that improves plant health by enhancing soil structure, stimulating root development, and increasing resistance to environmental stresses. It does not provide significant nutrients.
Seasol PowerFeed: A fertiliser that combines the benefits of Seasol with added nutrients, promoting vigorous plant growth, stimulating flowering and fruiting, and improving soil health.
Using both products in tandem can provide comprehensive care for your plants, addressing both their nutritional needs and overall health.
Even the best products require the right care and knowledge to unlock their full potential. Here are some practical tips to ensure you get the most out of Seasol PowerFeed for your garden:
Regular application is key. Follow the recommended rates and frequencies outlined on the product label or earlier in this article. Overfeeding can sometimes do more harm than good, so stick to the guidelines to maintain a healthy nutrient balance.
Seasol PowerFeed is most effective when applied during the plant’s active growing seasons — typically spring and summer for most Australian plants. This timing allows the fertiliser to support vigorous growth, root expansion, and flowering when plants need it most.
For best results, apply Seasol PowerFeed when the soil is moist but not waterlogged. Water your plants before application if the soil is dry. This helps nutrients absorb more efficiently and encourages beneficial microbial activity in the soil.
Enhance soil health further by combining Seasol PowerFeed with organic mulches such as bark, straw, or compost. Mulching helps retain moisture, regulate soil temperature, and provides additional nutrients as it breaks down, creating a more supportive environment for your plants.
Try to avoid applying Seasol PowerFeed during extreme heat, frost, or heavy rain. These conditions can reduce nutrient uptake or wash away the fertiliser before it has a chance to work. Aim to apply on calm, mild days for optimal absorption.
Remember that different plants have varying nutrient needs. Vegetables and flowering plants typically require more frequent feeding compared to established trees or shrubs. Adjust application frequency and concentration accordingly to suit your garden’s unique requirements.
Seasol PowerFeed can be used as a foliar spray for quick nutrient absorption through leaves, especially when plants show signs of nutrient deficiency. Spray during cooler parts of the day to prevent leaf burn and ensure the solution dries properly.
Seasol PowerFeed is a versatile and powerful fertiliser that can transform your gardening efforts, delivering healthier, more vigorous plants with stronger roots, abundant flowers, and improved resilience against environmental stresses. Its unique combination of fish extract, liquid humus, and essential nutrients makes it an excellent choice for both home gardeners and commercial growers.
