How to fertilize the newly budded boxwood bonsai

Boxwood bonsai is more afraid of direct light, so it is only necessary to provide scattered light to meet the growth needs in the process of planting and breeding. As for the newly transplanted yellow poplar downhill pile bonsai, it is usually necessary to keep it in the shade for a period of time to successfully take the pot and then transfer to the normal maintenance and management process. In order to promote the bursting of boxwood bonsai, it is usually necessary to apply some fertilizer to make its leaves more green and glossy, so as to improve the ornamental effect of the leaves. So, how to fertilize the newly bursting boxwood bonsai?

For Populus tomentosa bonsai, it is usually topdressing nitrogen fertilizer, spraying the trees with urea diluted by 2000 times, through the way of page topdressing to achieve the purpose of topdressing. And spraying thin foliar fertilizer on boxwood bonsai can be carried out all the year round. At the same time, combined with the usual watering, you can absorb a small amount of nitrogen. Topdressing of boxwood bonsai is often based on topdressing nitrogen fertilizer, focusing on letting bonsai spit green all the year round, so that bonsai keep branches and leaves luxuriant, but can not ingest phosphorus and potassium fertilizer.

Topdressing foliar fertilizer is the main form of extra-root topdressing, while the general use of quick-acting nitrogen fertilizer can often play a growth effect that can not be achieved by soil fertilization. For tree stump bonsai such as yellow poplar, foliar fertilizer can quickly and timely supplement the nutrients needed for tree growth, effectively promote photosynthesis and make up for the lack of nutrients in soil topdressing, so as to improve the survival rate of downhill stump and promote its rapid growth.

And as we all know, nitrogen is the formation of cell protoplasm, and originality is an essential "life element" in the process of metabolism. While boxwood bonsai is mainly for viewing leaves, the demand for phosphorus and potassium fertilizer is very little, and it is not suitable to deliberately supplement phosphorus and potassium elements, so it is often only necessary to supplement nitrogen fertilizer properly. And potassium often exists in the form of ions in the tree, and will not actively participate in the formation of important organic matter, so it can only play an important role in the reproductive growth of flowering and fruiting tree species.

For the fertilization problem of boxwood bonsai during the budding period, even if topdressing phosphorus and potassium fertilizer, it often can not play the role of supplementary nutrients to promote growth, but may also cause unnecessary side effects. Taking potassium as an example, it is mainly due to the increase of potassium ions with the topdressing of potassium fertilizer, the concentration of stomata in the guard cell fluid will increase instantly, so that the stomata will become larger, and the water in the tree will be easily lost. And the excessive accumulation of potassium ions also needs the corresponding energy to provide supply, which leads to the overall excessive consumption of the original accumulated nutrients of Populus tomentosa bonsai, which is very disadvantageous to the survival or growth of Populus tomentosa.

On the other hand, if too much potash fertilizer is applied to Huangyang bonsai, it is easy to cause leaf withering and shedding, and when the concentration is too high and the dosage is too high, it may also cause plant dyspnea, which eventually leads to plant death due to dyspnea. Topdressing potash fertilizer to boxwood bonsai will bring such consequences, while topdressing phosphate fertilizer will also produce a similar situation. Therefore, the cultivation of yellow bonsai is not suitable for intentional topdressing of phosphorus and potassium fertilizer.
