Саженцы по почте. Что делать до посадки?

Mail-order seedlings. We ordered seedlings from Garden Wood nursery through their online store https://gardenwod.ru/. However, the plants arrived too early, and we needed to keep them at home until warmer weather arrived. What should we do with the seedlings before planting? When should we plant them in the garden? How should we feed them? We answered all these questions in our video on the Garden World channel.
