Someone asked can you germinate a coconut in London, then, deleted the post before I could upload an answer. The answer is yes, you can germinate it indoors anywhere given sufficient humidity and warm temperatures. Place the coconut in a sealed container with a little water to increase the humidity. Ensure the three coconut “eyes” are not under water. (You don’t need to float the coconut. You only need water to increase the moisture in the container). You are creating a terrarium environment. So, warm temperatures are needed to simulate the tropics. Use a plant germinating heating pad or place it in a warm southern window (or grow light) or near a heater. Change the water each week. It takes 2 - 3 weeks to see new growth from one of the eyes. The new growth will have both the leaf/stem and the roots from the same eye. It takes about 3 months to 4 months to see the leaves turn green and the roots become long enough to plant, about 5 inches of roots. Fertilize with diluted fertilizer during water changes after the roots appear. Place it on its side to point the roots to the soil and the leaves upwards. Plant in well draining soil. Regularly fertilize. Note: The coconut must be free of mold or mildew as show in the photo especially around the eyes. This indicates the inside is rotten. The coconut must have water inside or it’s already too dry. 🍀🪴
