Korean pine will not mature until September of the following year, while larch will grow and mature in September of that year, and Pinus sylvestris will grow and mature in September of that year. Quercus mongolica will grow and mature in 10 of the following year.
2, plastic pruning
When pruning pine trees, all the lateral branches near the base can be cut off to promote the trunk to grow straight, and then the branches that are too strong and too strong can be cut off to reduce the consumption of nutrients. Moreover, the trimmed wound can't touch water, so it's best to apply plant ash to make it heal quickly.
Step 3 supplement nutrition
In the process of cultivating pine trees, it is necessary to apply decomposed farmyard manure once every two months to improve the growth rate of plants. However, attention should be paid to the amount of fertilizer applied, and it is best to dilute the fertilizer before use, or water the pine trees in time after fertilization to reduce the fertilizer concentration.
4. Water
Pine trees have a great demand for water, so it is necessary to observe the changes of soil regularly during reproduction. If the soil is found to be white, water the pine trees in time to keep the soil moist, but it is not necessary to water the pine trees in rainy season or when the soil is wet to avoid waterlogging.
