How should pine and cypress be cared for in winter to survive the cold safely?
Pine and cypress, together with bamboo and plum, are known as the "Three Friends of Winter." They are widely distributed in southern North China and the East China region, and are also commonly used as ornamental garden trees. So, how do pine and cypress overwinter? 1. How do pine and cypress overwinter? Pine and cypress overwinter by adjusting the color of their leaves. Although their leaves are still green in winter, the color is much poorer than in spring, summer, and autumn. This is because winter temperatures are low, the production of chlorophyll in the leaves is restricted, while anthocyanins increase relatively, so the leaves take on a somewhat reddish hue. The color change can weaken photosynthesis in the leaves, slowing the tree's physiological activity and thereby ensuring that pine and cypress survive the winter safely.

How to Propagate Pinellia ternata? A Detailed Guide to Common Propagation Methods
Pinellia ternata, also known as Diwen, is a medicinal herb with effects of drying dampness and resolving phlegm, descending adverse qi and stopping vomiting, and reducing boils and swellings when used fresh. It is cultivated in many regions, so how is Pinellia ternata propagated? 1. Tuber propagation: After Pinellia ternata has been cultivated for 2-3 years, the underground tubers can be dug up after the seedlings wither in June, August, and October each year. Select small tubers with a transverse diameter of 0.5-1 cm that are robust and free of pests and diseases for use as seed. Mix the seed tubers with fine sandy soil of moderate moisture, store them in a ventilated and cool place, and take them out for planting in winter of the same year or spring of the following year. Spring planting is preferable; autumn and winter planting yields low output. Spring planting should be done early rather than late. In the warm Jiangnan region, drilling in rows can be done in mid-December on finely raked and leveled beds. With a row spacing of 12-15 cm and a plant spacing of 5-10 cm, open furrows about 10 cm wide and about 5 cm deep, and arrange two staggered rows in each furrow, placing the buds upward in the furrow. After planting, apply a layer of mixed fertilizer soil on top (made by evenly mixing decomposed compost and barnyard manure with human and livestock manure, burnt soil ash, etc.). The dosage is about 2000 kg per mu. Then, lift the furrow soil to cover it, about 15-7 cm thick. About 100 kg of seed tubers are needed per mu. Properly dense planting of Pinellia ternata results in uniform seedling growth and high yield. If too dense, the seedlings grow weakly and weeding is difficult; if too sparse, there are few seedlings and many weeds, and the yield is low. The covering soil should also be moderate. If too thick, emergence is difficult, and although the bulbils will be large in the future, they often form in the soil and are not easy to harvest; if too thin, the seed tubers are prone to shrinking and cannot germinate. After planting, if dry weather occurs, water promptly and always keep the soil moist. <p style="text-indent:2em;">2. Bulbil propagation</p> <p style="text-indent:2em;">Each stem and leaf of Pinellia ternata bears 1 bulbil. The quantity is sufficient, germination is reliable, and the maturity period is early, making it the main propagation material. In summer and autumn, when the old leaves are about to wither, the bulbils have matured and can be collected for propagation. Dig holes and sow at a row spacing and plant spacing of 10*8 cm, planting 2-3 grains per hole. They can also be propagated by covering with soil in place, that is, each time a batch of seedlings withers, cover with soil once, to the extent that the bulbils are not exposed. At the same time, apply an appropriate amount of mixed fertilizer. This can not only promote the germination and growth of bulbils, but also add fertilizer to the mother tubers, achieving two goals at once and helping increase yield.</p> <p style="text-align: center;"></p> <p style="text-indent:2em;">3. Seed propagation</p> <p style="text-indent:2em;">Pinellia ternata over 2 years old can bloom and bear fruit successively from early summer to autumn and winter. When the spathe turns yellow and droops, collect the seeds and store them in wet sand. In early to mid-March to April of the following year, drill shallow furrows on the seedbed at a row spacing of 5-7 cm, sow the seeds, cover with 1 cm thick fine soil after sowing, and cover with grass to keep warm and moist. Seedlings can emerge in about half a month. However, the emergence rate is relatively low, so it is generally not used in production.</p>
