How to Grow an Avocado from Seeds Easy Method 1. Prepare the Seed: Wash the seed and insert toothpicks around its equator. These will hold the seed above the water. 2. Suspend the Seed: Place the seed over a glass or jar filled with water, making sure the bottom half is submerged. 3. Change the Water: Check and change the water regularly to keep it fresh. 4. Wait for Germination: Place the seed in a sunny location and wait for roots to emerge, usually between two and six weeks. 5. Transplant: Once roots and a leafy stem appear, transplant the seed into well-draining soil, leaving the top half uncovered. 6. Tree Care: Water regularly and place it in a sunny location. Prune occasionally to encourage growth. Growing your own avocado tree is a fun and satisfying way to enjoy fresh avocados at home. Try it and enjoy the fruits of your labor.
