It can grow into a big tree. Poplar seedlings are developed from poplar seeds. Poplar is a small arboreal plant with a height of about 2-5 meters. In Shuyang, also called Evergreen, it can be used as a very beautiful potted plant. Before planting boxwood seedlings, soil should be selected. In order to obtain sufficient nutrients during its growth, we generally choose fertile humus soil and river sand as basin soil to plant Buxus buxus seedlings, and in addition, we must disinfect the soil. After planting, put poplar seedlings in a cool place for a period of time. It takes about a week for poplar seedlings to receive sunlight. Poplar seedlings like wet environment, so they should be watered more during the growth process to keep the soil wet, but they should not accumulate water for a long time, otherwise the leaves of poplar seedlings will fall off or the roots will rot. During the growth and development of poplar seedlings, it is necessary to prevent the invasion of pests and diseases. The main pests are aphids and longicorn beetles. They will breed on the leaves and eat the branches and leaves of poplar seedlings. We can spray some thiacloprid spray to prevent it.
