Whenever summer comes, the tip of the plant will turn yellow. After the autumn, some tips will die, which will greatly affect the ornamental value. What causes this phenomenon? Five-pin pine is named after the five-leaf clumps. The plants are short, grow slowly, have short branches and branches, elegant postures, and beautiful trees. They are the best species for making bonsai. Pine needles In midsummer and early winter seasons, some needles in the middle of the shoots often appear irregularly yellow, which is the general manifestation of normal metabolism of the pine needles. After investigating soil pH, temperature, and moisture, the main reason was not that fertilization was improperly applied, but mainly due to poor water control.
First, the basin soil is often too wet, together with poor drainage and water accumulation in the basin, causing anoxic soil, causing rot, yellowing the needles; second, sun exposure, basin soil dry, five-pin pine There will be a tip of the tip of the tip of the needle, if it continues to lack water; the plant will eventually die; the third, five-pin pine put room for a long time, lack of light, air, in violation of the habit of receiving light in the outdoors, or suddenly When you move to outdoor exposure, you may also experience browning.
For the above reasons, we must actively take appropriate preventive and rescue measures, spray “drug-resistant membranes†for drought and flood prevention, prevent water transpiration, anti-sun exposure, and moisture retention in the dry season, and reduce the weather in the rainy days to normalize the pine needles. Growth has an adverse effect. By using "new high-fat" membranes, the balance of water in the plants can be adjusted so that plants can prosper in harsh environments.
