Summarize this article:

Sandy soil ensures a lack of water logging. Avoid clay based soil and whatever type of soil you use, ensure that it allows for free flowing irrigation as water-logging can lead to damaging the tree. Buy cashew seeds specifically for growing from gardening supply stores. Cashews sold for consumption, even raw ones, are not viable because their protective shell has been removed. If you plant multiple trees, plant them 30 feet (9.1 m) away from each to ensure adequate room for growth.  Using the freshest seed possible will provide the best results so plant as soon as you get hold of it. Cashews can’t sustain in areas with heavy rainfall or wind but can thrive in extremely hot temperatures up to 50 °C (122 °F). Because of this, tropical areas that are very warm and receive medium levels of rainfall are ideal. If there is too much rain, the roots will drown and the tree will die. Cashew trees thrive in warm, sunny climates and if the tree doesn’t receive this much sunlight then it will grow slowly and eventually may not even flower. Ideal locations for growing cashew trees include:  Open fields Farmland On top of hills that will not be too windy

Summary:
Plant your fresh cashew seed in sandy soil. Plant your seeds 10 centimetres (3.9 in) deep to make room for expansion of roots. Use an area that receives moderate rainfall. Ensure your tree has access to at least 6 hours of sunlight per day.
