Fir piles are sometimes used for the maintenance of greening projects. At this time, fir piles mainly play a supporting role, such as some large climbing plants. After planting supporting seedlings, in order to prevent the seedlings from lodging or shaking the root system, the seedlings should be supported. There are the following types of supports: Character brackets, 3-angle brackets and tic-tac-toe brackets. If it is a seedling, such as a bamboo forest, it can be covered with netting. The supporting materials are fir stakes, bamboo, iron wire, etc. The support must be firm and powerful, such as using wire to pull the 3-angle bracket, and the wire must be tight , the pile should be tilted 45 degrees to the ground.

A small series of fir wood piles tells flower farmers a little knowledge: If the leaves of green plants on the table are yellow, they should be cut off immediately, so that the yellow leaves will not absorb and waste nutrients. This little knowledge is really novice knowledge, for Useful for people who know nothing about plant protection.

Sometimes it is best to apply some fertilizer, which is helpful to restore longevity. In the early stage of seedling planting, the root system has low fertilizer absorption capacity. Therefore, it is appropriate to topdress the roots. Use urea, ammonium sulfate, potassium dihydrogen phosphate and other quick-acting fertilizers to prepare a concentration of 0.5%-1% fertilizer solution. Spray on the leaves in the morning and evening or on cloudy days, and then spray again on rainy days. After the roots sprout, you can fertilize the soil. Apply dilute fertilizer frequently to prevent root damage. Just buy some nutrient solution.
