Saudi Arabia has announced plans to plant 10 billion native trees at a rate of one million per week. That's about 50 million trees a year. Is this really possible in the dry desert of Saudi Arabia? has the water requirement of these trees been calculated? In Iran and Khuzestan, which have more suitable conditions, in the warmer months, seedlings need to be irrigated 3 to 4 times a month. Almost every seedling needs about 1 cubic meter (1000 lit) of water in a year. Thus, 50 million trees in a year need 50 million cubic meters of water. If the amount of water needed to produce seedlings in the Nursery is added to this amount of water, a very large volume of water is needed each year. This amount will double for the second year and triple for the third year. Will this volume of water be easily supplied in the dry desert of Saudi Arabia? It seams, this is impossible with such a large scale! . We have to wait for the result. I hope and pray they succeed. for more information you can see the bellow : https://www.al-monitor.com/originals/2021/05/saudi-arabia-plans-plant-10-billion-trees-desert
The Saudis are doing it, and if they are native trees local to the area, should only require a dingle watering when planting. We plant tree seedlings by the tens of millions each year in the arid West of the USA and only give them one watering when planting and that is all. The seedlings we plant are very small bare root or grown in Ray Leach "Cone-tainers" (Trademark) as the picture shows.
If you plant anything larger, then those plants would require a lot of water for a period of time to get established.
The Cone-tainer is designed to keep the roots growing straight down and not spiraling and very easy to remove the plants when planting.
Adding a few liters of mulch around the bases of the seedlings could also help the plant survival, maybe more than additional water.
