Growing kalo taro in Hawaii requires specific soil conditions to ensure healthy growth. Here are the recommended soil pH, N-P-K (nitrogen, phosphorus, potassium) ratios, and the percentage of topsoil to smaller black cinder for successful kalo cultivation:
- Kalo thrives in slightly acidic to neutral soil conditions. The ideal pH range for kalo is between 5.5 and 6.5.
- The nutrient requirements for kalo can vary depending on soil conditions and specific cultivars, but a general guideline for N-P-K ratios is as follows:
- Nitrogen (N): 1.5-2.5%
- Phosphorus (P): 0.5-1.0%
- Potassium (K): 2.5-3.5% These ratios can be adjusted based on soil tests and the specific needs of your kalo plants.
Percentage of Topsoil to Black Cinder:
- Taro plants benefit from well-draining soil with good moisture retention. In Hawaii, it’s common to use a mix of topsoil and cinder for growing kalo. A common recommendation is to use a mixture of 70% topsoil and 30% black cinder or similar volcanic soil amendments.
- The use of black cinder helps improve drainage while retaining essential moisture, which is crucial for kalo cultivation.
It’s important to note that these recommendations can be adjusted based on soil tests and local conditions, as soil composition can vary from one location to another within Hawaii. Additionally, kalo cultivation may have specific requirements based on the particular taro variety you are growing. Regular soil testing and monitoring can help you fine-tune your soil preparation for the best results. For more information
