Step 1: Prepare the seed. Place a whole, in-shell macadamia nut in a pot of warm water for about 24 hours. A viable seed will sink in water and have a tight kernel. Step 2: Plant the seed: Use a small but deep pot to accommodate the taproot. Orient the seed so the taproot can grow down and the shoot can grow up. Cover the nut about 1 inch deep in the soil. Step 3: Place the pot in a warm and shady location. Keep moist, but avoid waterlogging. Germination can take anywhere from 30 to 120 days. A small tail with roots will emerge first, followed by the shoot and leaves. Step 4: Transplant Do not disturb the seedling until it has developed a good root system and a few sets of leaves. Keep the original nut attached as it provides nutrients as it decomposes. Choose a suitable final location: Plant in full sun, in deep, well-draining, and fertile soil, and be mindful of the tree's eventual size. It's also crucial to protect young trees from frost, as macadamias are intolerant of cold. Ship USPS Ground Advantage. Ship only the nuts, no skin due to shipping weight. Thanks.
