Cultivation methods and precautions of sycamore

1. Maintenance methods

1. Substrate selection: It is best to choose relatively loose and breathable soil, and the soil layer should be thicker to facilitate the rooting of the sycamore. It can grow in both acidic and neutral soils, but its survival rate is low in alkaline soils, and puddles are also not conducive to the growth of sycamore.

2. Temperature management: Sycamore is suitable for growing in a warm and humid environment. It is afraid of cold and needs insulation treatment when the temperature is below minus 3℃ in winter. Similarly, if the temperature is too high in summer, it will also affect growth. The optimal temperature is roughly 15℃-25℃.

3. Water management: Water the sycamore seedlings frequently in the early stages, and try to keep the soil slightly moist. During the rapid growth stage, increase the amount of water and reduce the number of waterings, and stop watering in the later stage.

4. Nutrient management: Deeply plow the soil around the tree roots every autumn, and add base fertilizers such as oil residue and feces. In addition, during the fruiting period, a mixture of superphosphate, ammonium nitrate and bean cake can be applied.

2. Breeding techniques

1. Sowing: Sowing is a common method of propagation. When the sycamore fruits ripen in autumn, pick the bulbs, dry them and take out the seeds. They can be sown in the autumn of the same year, or stored for sowing in the spring of the following year. The recommended row spacing when sowing is 250mm, and then cover with a layer of soil about 15mm thick.

2. Wintering: The weather is very dry in winter, so you need to prune the branches before wintering to prevent water loss. The temperature in the north is low in winter, so you can wrap the tree trunks with a layer of straw mats before winter to keep them warm.

3. Problem diagnosis and treatment

1. Frost moth: It feeds on the leaves of sycamore trees, and in severe cases it will eat the entire leaf. Turning the soil several times in winter can kill some insect pupae. After the disease appears, you can spray the back of the leaves with DDT or Lecithin mixed with water.

2. Leaf falling: The plant may be infested with sycamore bugs. You can spray the plant with omethoate once every week. Make sure to use enough medicine and spray evenly.

IV. Other issues

1. Can it be grown at home? The branches and leaves of the paulownia tree are lush and green, so it can be grown at home. And the management requirements are not strict, so it is very suitable for planting in the courtyard.

2. Can it be planted in the ground: Yes. After growing up, the sycamore is mainly used as an urban greening tree. It requires loose soil, is more water-efficient, and has a higher survival rate when planted in the ground.
