Planting avocados: soil or water germination?

My conclusions after planting 50+ Avocado trees

Plant avocados in water

…if you are new to gardening, and want to see the very long germination process. Transplants of seedlings with water roots are less vigorous, but it’s easier to keep tabs on germination when it is visible.

Plant avocados in soil…

…if you are an experienced, attentive, and patient gardener, and want a healthy, vigorous plant with a comprehensive root system. You have to remember to keep a seed with no signs of growth watered for two or three months, but the resulting plant is healthier.
