Excuse me, what tree is this?

1, light watering: Osmunda japonica is a light-loving plant, so it must be placed in an outdoor sunny place during the growing season. At the same time, Osmunda japonica requires a lot of water during the growing season, so it is necessary to keep the soil moist. Keep the basin soil moist in spring and east, water it once in the morning and evening in summer and autumn, and increase the watering times in high temperature season.

2. Fertilize regularly: Osmunda japonica is a fertile plant. Lack of fertilizer in potted Osmunda japonica will lead to weak branches and yellow color, resulting in weak plant growth and little or no flowers, but excessive fertilization will lead to excessive growth of branches and leaves. Fertilization can be increased in spring and summer, decreased after autumn, no fertilization in winter, no fertilization in summer rainy season and high temperature at noon.

Fertilization of Osmunda japonica should be based on the principle of thin fertilizer and diligent application. Nitrogen, phosphorus and potassium fertilizer should be applied together in the first half of each month to promote its bamboo shoots, potassium dihydrogen phosphate should be applied once in the second half of each month to promote the growth of flower buds, and flowering fertilizer should be applied once in the second half of July and the first half of September to make the flowers more colorful.

3, plastic pruning: Osmunda japonica has thick branches and a large amount of new buds, which is very resistant to pruning. After flowering, the residual flowers should be cut off, which can prolong the flowering period. At the same time, some cross branches, diseased branches and radiation branches should be cut off in time to avoid consuming excess nutrients. At the same time, in order to beautify the shape, the full terminal buds of other branches are generally cut short by about cm.

4. Change pots in time: Pot soil for potted Osmunda japonica needs to be changed every two to three years, and mixed with loose mountain soil, pastoral soil and fine river sand to prepare culture soil. When changing pots, organic fertilizers such as bone meal and bean cake powder can be used as base fertilizer and mixed on the soil surface to prevent the fertilizer from directly contacting the root system, so as to avoid burning the root system and affecting plant growth.
