It is a nutrient-rich by-product obtained after extracting oil from groundnuts and provides a slow release of essential nutrients that support healthy plant growth.

Whether you’re growing vegetables, fruit plants, flowering plants, or herbs, groundnut cake can be an excellent addition to your organic gardening routine.

🌱 Why Use Groundnut Cake?

Groundnut cake offers several benefits for home gardeners.

Advantages

• 🌿 Slow-release organic nutrition
• 🍅 Encourages healthy leafy growth
• 🌱 Improves soil biological activity

💧 Preparing Groundnut Cake Liquid Fertilizer

Instead of applying groundnut cake directly around plants, many gardeners prepare it as a liquid fertilizer.

Simple Preparation Method

1. 🌰 Add a handful of groundnut cake to about 1 litre of water.
2. 🫙 Leave the mixture for 2–3 days in a covered container.
3. 🔄 Stir occasionally during soaking.
4. 💧 Dilute the filtered liquid with additional water before application.

This liquid fertilizer can be applied around the root zone of vegetable plants.

Applying it as a liquid also helps reduce the chance of attracting ants to solid pieces of groundnut cake.

🌿 How Often Should You Apply It?

Groundnut cake liquid fertilizer can be used periodically during the active growing season.

General guidelines:

• 🌱 Apply around the root zone.
• 💧 Water normally after application if needed.
• 🌿 Avoid excessive use.
• 🌞 Apply during cooler parts of the day.

Observe plant growth and adjust the application frequency according to the crop and growing conditions.

🌰 Homemade Alternative

If groundnut cake is not readily available, a simple homemade mixture can also be prepared.

One common method is:

• 🥜 Soak raw peanuts overnight.
• 🥣 Grind them into a paste.
• 🍯 Add a small quantity of jaggery.
• 🫙 Allow the mixture to ferment for about 24 hours.
• 💧 Dilute well with water before application.

This homemade preparation can also be used as an organic liquid fertilizer for garden plants.
