The company is very concerned about the environment and sustainability, so as part of this promotion, marked potted Christmas trees purchased from the nursery can be returned by the specified date. You can buy 50% of the price of the pine tree at the nursery. The returned live pine trees will be sent to educational institutions for planting with the help of the School Garden Foundation. At the beginning of 2021, Oasis Gardening donated nearly 500 loaned pine trees. The nursery's website also provides useful information on caring for Christmas trees.
