The milk provides calcium and nutrients, while the plastic can helps retain moisture and warmth in the soil. This combination boosts root development, prevents diseases, and encourages fast vine growth.
- Milk enriches soil with vital nutrients like calcium and potassium.
- Plastic cans protect roots and stabilize soil temperature.
- The method reduces fungal diseases naturally.
- Results include faster flowering and larger fruit size.
Why Australian Gardeners Love This Hack
This technique became popular because it’s both budget-friendly and eco-conscious. Instead of chemical fertilizers, it uses organic ingredients that are safe for soil health and the environment. Many gardeners report getting double the harvest compared to traditional growing methods.
- Completely safe for organic gardening.
- Reuses household waste materials effectively.
- Boosts fruit weight and overall plant yield.
- Ideal for small gardens or backyard setups.

Step-by-Step Guide to Grow Giant Squash Using a Plastic Can and Milk
- Step 1: Prepare the Soil
Start by loosening the soil in a sunny location. Mix compost and a little sand to improve drainage. Healthy, well-aerated soil helps roots absorb the nutrients from milk effectively.
- Step 2: Create the Plastic Can Setup
Cut a medium-sized plastic can (like a milk jug) in half. Place the bottom part near the squash plant’s roots. This acts as a funnel for watering and nutrient feeding directly to the base.
- Step 3: Mix the Milk Solution
Combine one cup of milk with four cups of water. Stir it well and pour it into the can once every three days. The diluted milk provides calcium that strengthens the plant’s stem and improves fruit firmness.
- Step 4: Water and Monitor Growth
Keep the soil moist but not waterlogged. The plastic can helps prevent evaporation, ensuring consistent hydration. Within 10–15 days, you’ll notice greener leaves and stronger vines.
- Step 5: Support the Growing Vines
As the squash expands, use small sticks or a trellis to keep vines upright. This allows better air circulation, reducing fungal issues and encouraging larger, more uniform fruits.
- Step 6: Harvest at the Right Time
Giant squash is ready when the skin turns deep orange or yellow, depending on the variety. Gently twist the fruit off the vine, leaving a small stem attached to extend freshness.

Extra Tips for Better Results
- Use whole milk, not skimmed, for richer calcium content.
- Always water early in the morning for maximum absorption.
- Rotate crops yearly to avoid soil fatigue.
- Add crushed eggshells for extra nutrients.
- Keep mulch around the plant base to retain soil moisture.
