Why Accurate Soil Calculation Matters

Accurate soil calculation is crucial for several reasons:

2. Environmental Impact: Over-purchasing soil can contribute to waste, which is unsuitable for those looking to garden sustainably.

3. Plant Health: The right amount of soil ensures your plants have enough space to spread their roots and absorb necessary nutrients.

Tips for Soil Preparation

1. Test Your Soil: Before adding new soil, it’s a good idea to test your existing soil’s pH and nutrient levels.

2. Consider Soil Type: Different plants require different types of soil. Choose the soil best suited for the plants you’re growing.

3. Add Compost: Mix some compost with your soil for an extra nutrient boost.

4. Water Well: Once your soil is laid, give it a good watering to help it settle.
