To ensure your soil is optimal for Cider gum, conducting soil tests is crucial. Test for pH levels, nutrient content, and soil texture. Soil pH can be tested using a simple kit available at garden centers or by sending a sample to a professional lab. Analyzing nutrient levels, specifically nitrogen, phosphorus, and potassium, will help you understand what amendments might be necessary. Texture tests can be done by feeling the soil or using the jar test method, which involves shaking soil in water and observing the separation of layers.
