Red Torch Ginger
Growing torch ginger is possible in a range of soil types. A major problem when growing torch ginger plants is potassium deficiency. Potassium is necessary for the correct uptake of water, which is necessary for the optimum growth of this large plant.
Add potassium to the soil before growing torch gingers by working it into unplanted beds to about a foot deep. Organic means of adding potassium include the use of greensand, kelp or granite meal. Test the soil.
When growing these plants in established beds, fertilize with a food that is high in potassium. This is the third number on the fertilizer ratio displayed on the packaging.
Once the potassium is right in the soil, watering, an important part of learning how to grow torch ginger successfully, will be more beneficial.
