Because of its rich and simple appearance, beautiful and solemn, it has high ornamental value. Therefore, it symbolizes purity and immortality in feng shui, which means longevity and good luck. So how should the five-needle pine be maintained? I think as long as we do the following, we can make the five-needle pine evergreen all the year round and have dense branches and leaves.
1, placed in a sunny and well-ventilated window or balcony.
Five-needle pine likes light, and it needs at least 5-6 hours of light every day to meet the normal photosynthesis and ensure the green and yellow needles. If the environment is too humid and easy to breed germs, it must be placed in a dry and ventilated place. Considering the strong sunshine in summer, it is easy to get sunburned in the sun, so it is necessary to shade properly.
2, according to the climate and weather changes, strictly control the watering.
Five-needle pine is naturally afraid of water accumulation, but it is drought-resistant, so watering must be controlled well, and it cannot be watered too much at a time. While watering, we should also ensure the supply of water on the leaves. Strictly follow the principle of seeing dry and seeing wet. In spring and autumn, it is/kloc-0 once a day or once every two days, depending on whether the basin soil is wet or dry. Twice a day in summer, not too much water once, once every 3-5 days in winter. Pay attention to the change of water temperature and external temperature when watering in winter, and it is best to keep the same.
3. Rational fertilization according to different growth stages.
Five-needle pine is barren, although the demand for fertilizer is not great, it is generally in accordance with? Fat, thin and little? The principle can be. But in the growing period, it is best to apply it once every 10 day to promote germination; When the temperature is hot in summer, apply thick fertilizer lightly, 15 once a day to ensure nutrient supply and promote flower bud differentiation. Autumn grows fastest and needs the most fertilizer. Normal fertilization ensures axillary bud germination. One month before winter, stop fertilizing.
4, timely pruning, control modeling and growth.
Pruning of five-needle pine is very important. Because once the pruning is not good, it is easy for the leaves to turn yellow, the pine needles to fall off and the growth is not good. So we usually trim it regularly every winter (11-February). Considering the slow growth of Pinus quinquefasciatus, it can't be rebuilt. From April to May every year, the five-needle pine should be topped to avoid steep growth and control its growth; In June and July, the leaves can be thinned, and the diseased leaves and some branches of the old leaves can be cut off to keep the appearance beautiful.
5, check the branches and leaves, take measures to prevent and control pests and diseases.
There are not many pests and diseases of Pinus pentaphylla, but they often appear under the condition of poor maintenance environment and improper management. Therefore, it is necessary to pay more attention to observation when maintaining in order to get timely prevention and treatment. After the occurrence of common diseases and insect pests such as leaf blight and stem rot, we first pull out the diseased leaves, then keep them ventilated and dry, and use fungicides such as thiophanate-methyl and carbendazim for chemical control. If it is an insect pest (aphid, red spider, scale insect), cut off the diseased branches and leaves first, and catch and kill them with a small amount of manpower. If there is a lot of omethoate, just spray it with water and keep it ventilated and lit.
Summary: It is not difficult to maintain the five-needle pine, but you should be careful. Don't water and fertilize too much at ordinary times, and keep up with the pruning. Once abnormal conditions such as pests and diseases are found, we should pay close attention to treatment, so that the five-needle pine can flourish and keep its vitality forever!
