Betula platyphylla

When Betula platyphylla is used as a small indoor pot, the seeds can be sowed in the seedling pot first, and then the seedlings with similar growth rate will grow neatly in the 3-inch pot after germination. When transplanting, you should be careful not to hurt the roots. in general, three-inch pots are best planted with more than five seedlings to grow more luxuriantly, and pots can choose quaint pottery pots or gorgeous blue-and-white porcelain pots, which can set off the delicate leaves of silver birch. Finally, you can put it in the window or the room where there is enough light. Because the seedling is limited by the basin, it will not grow too big and can be maintained for a long time, but if there is not enough light in the cultivation place, the seedling will be easy to grow and affect its appearance.
