How to grow Pyrostegia venusta (flame vine)? A complete guide to its cultivation methods
Soil
Because flame vine has low requirements for soil, when growing it we need to plant it in soil rich in organic matter with good drainage, and the soil layer should be deep. Generally, a mix of leaf mold, garden soil and sand can be used, with some decomposed fertilizer or bean cake added as a base fertilizer.
Light
Flame vine likes a growing environment with ample light and a warm climate. Maintaining sufficient light every day helps it bloom more vigorously.
Temperature
The suitable temperature for flame vine growth is 18 to 25 degrees. It is not cold-tolerant and needs to be kept at a relatively high temperature in winter; for overwintering it generally needs to be above 10°C. In northern regions it can be placed indoors in a spot with ample sunlight.
Watering
Watering flame vine should follow one principle: water when dry, and let it dry between waterings; there should be no standing water in the pot. Generally, in summer when temperatures are high, water more; sometimes it is necessary to spray the flower pot and the ground to raise air humidity and lower the temperature. In autumn, watering should be appropriately reduced.
Fertilizing
For fertilizing flame vine, during the growing season generally apply a dilute liquid fertilizer once every two weeks. During the bud-forming stage, apply phosphorus fertilizer once or twice; after the flowers fade, also apply a nitrogen fertilizer once. During overwintering, control the amount of watering and stop fertilizing.
So, do you know what matters need attention during the cultivation of flame vine?
Cultivation methods for flame vine
Cultivation methods for flame vine. Flame vine is propagated by layering or cuttings. Layering can be done in spring or summer; roots begin to form in about 1 month, and in about 3 months it can be separated from the mother plant and transplanted. Cuttings are generally taken after flowering in spring; if there is a greenhouse, they can be taken all year round. In early summer, softwood cuttings are taken from young branches, cut into sections of more than 10 cm with node buds, and roots form in more than 20 days. Old stems can also be used for cuttings, that is, selecting robust old stems sprouting from the base, which can reach more than 2 m in length, and inserting them into fertile sandy loam, keeping them in half shade; roots begin to form in about 50〜60 days. In that year let them grow branches and leaves freely; in winter transplant them with soil to the foot of a wall or an open spot in front of a door, support them with bamboo, and they can bloom the following year.
Flame vine likes light and is not strict about soil, but when cultivated in fertile soil rich in organic matter, well-drained and with a deep soil layer, it grows more vigorously. After planting, the first watering should be thorough, and shade is needed. When the seedling grows to about 70 cm tall, a trellis should be set up, and its branches should be trained onto the trellis; pinching should also be done to encourage side branches to sprout, which helps it bloom more. Flame vine grows fast, blooms abundantly, and has a long flowering period, so fertilizer and water must be sufficient. During the growing period, apply a top dressing once a month. The top dressing should preferably be decomposed dilute bean cake water or compound chemical fertilizer, to promote lush branches and leaves and flowers all over the branches. For potted flame vine, it is best to choose a deep cylindrical tile pot or a large flower pot. The growing medium should mainly use leaf mold, garden soil, mountain soil, etc., and an appropriate amount of decomposed compost, bean cake, bone meal and other organic fertilizers should be applied as base fertilizer. After planting, management is the same as for ground planting. It grows better when planted in loose, fertile, well-drained, slightly acidic soil. For potted plants in the Jiangnan region, they need to be brought indoors to overwinter in winter. It is best to place them for care on a balcony with ample sunlight in a closed room with glass windows.
>Ornamental value and uses
Flame vine is a large tropical climbing plant with extremely many branches, reaching several meters to several dozen meters in length and growing by climbing. If it climbs on a wall or flower trellis, it is lush and green like a curtain hanging down. When the flowering season arrives in winter and spring, the long flower branches can sprout from every leaf axil, and the panicles gather the flowers. Strings of flowers hang like firecrackers welcoming spring; because there are many branches, there are also many strings of flowers, interwoven with each other into a large expanse, very lively and also spectacular.
In South China, Taiwan, China, Hainan Island and Xishuangbanna in Yunnan, flame vine can all be planted in the open. It is suitable for ground planting in courtyards and parks as flower walls and flower pergolas, covering earth slopes and rockeries, or used for vertical or ground-cover greening on multi-story balconies. When the flowering season arrives, it is like exploding firecrackers and fireworks, and it also coincides with the Spring Festival, adding even more red light and festive auspiciousness. Truly, "Curl after curl, cluster after cluster, climbing several layers; lush and green, a green curtain on the window. Twinkling and sparkling, strung together in strings; skillful hands hang up red firecrackers. The warm sun reflects their brilliance as if about to burst; the flowers bloom right in the midst of the festival." These lines vividly express the flowering characteristics of flame vine. Nowadays, in the Nanshan Scenic Area of Sanya, Hainan, from January to February, flame vines bloom in patches competing with one another, and it has become a beautiful sightseeing highlight.
As early as the 1960s, the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences had planted flame vine. The author, moved by it, once wrote the poem "On Flame Vine": "Here there is no winter and no plum, the cold wind does not reach the green courtyard; ask who can know the meaning of spring, firecrackers welcome spring in red strings." We believe that in the Yangtze River basin, planting flame vine by combining greenhouses and open-air cultivation can be attempted. Flame vine is a festive flower. Whether it can be moved north to subtropical regions for planting: according to surveys, Fuzhou, Xiamen, Quanzhou, Sanming and other places in Fujian all have open-air plantings, growing and flowering well.
Annual flowersRefers to herbaceous plants that complete one life cycle within one year, including sowing in spring and summer, flowering and fruiting in summer and autumn, and the individual dying in the same year after the seeds mature. Such as Impatiens balsamina, Salvia splendens, Celosia argentea, etc. Biennial flowers refer to herbaceous plants whose growth cycle spans two years, that is, sowing in autumn of the first year, seedlings overwintering, flowering and fruiting in spring or summer of the second year, and then dying. Such as Viola tricolor, Pericallis hybrida, Dianthus chinensis, Antirrhinum majus, Calendula officinalis, etc. In fact, Salvia splendens and Calendula officinalis seeds can be sown both in spring and autumn. If sown in spring they are annual flowers, while if sown in autumn they are biennial flowers, so it is more appropriate to use annual and biennial flowers together.
How to plant flame vine: cultivation methods for flame vine
Flame vine is also called firecracker flower because it blooms during the Spring Festival, and its bright red flower color suits the festive atmosphere, hence the name. Flame vine grows quickly, and its branches and leaves remain evergreen all year round. It is a very good climbing greening plant and can be used to cover balconies, walls, etc. Below, the editor will introduce to you how to plant flame vine and the cultivation methods for flame vine.How to plant flame vine
1. Potting soil
Whether planted in the ground or in pots, the size of the planting hole and pot for flame vine needs to be somewhat larger, so that a large amount of organic humus can be applied as base fertilizer. Flame vine is not strict about soil, but heavy clay soil is unfavorable for its growth. It grows best in well-drained, fertile sandy soil rich in organic matter.
2. Light
Right after flame vine is planted or potted, it should be properly shaded, and only after it resumes growth can it fully receive sunlight. Flame vine likes light and can also tolerate slight shade; the cultivation site should maintain good ventilation. Flame vine is a tropical plant, likes warmth, and is not cold-tolerant; the winter temperature should not be lower than 10 degrees.How to plant flame vine
3. Water and fertilizer.
When planting, the hole dug should be somewhat larger, and decomposed organic fertilizer should be applied. For open-field cultivation, cultivate soil and fertilize 2-3 times each year; for potted plants, fertilize once a month. Flame vine is not drought-tolerant and is slightly tolerant of wet conditions. After planting, water thoroughly, once every 2-4 days; during the growing period, water 1-2 times a day.
Water promptly when the weather is hot. During the growing period, apply decomposed bean cake water about once a month, and then it will grow vigorously and bloom abundantly. In summer, apply once a month a liquid fertilizer soaked from hoof and horn. After the Start of Autumn, the plant enters dormancy and fertilizing should stop. In winter, appropriately reduce watering, mainly according to soil moisture, about once every 2-3 days.How to grow flame vine
4. Pruning
When the plant is about 2 m tall, a trellis needs to be set up to train its branches onto the trellis, and pinching should be done to encourage more side branches and more flowers. The plant grows by attaching itself with tendrils. During the growing period, do not turn the vines or break the tendrils, otherwise it will affect its absorption of water and nutrients, causing poor flowering or even no flowering.
Notes on growing potted flame vine
1. Choose a large, deep cylindrical tile pot for planting. Because flame vine grows rapidly and has luxuriant branches and leaves, the growing medium should preferably use mountain soil; where there is no mountain soil, leaf mold or peat soil can be used as the main component, plus part compost soil and a small amount of bone meal.
2. Water and fertilize reasonably. Flame vine likes moist soil, so during the growing season it is appropriate to keep the potting soil moist often. In dry seasons and hot summers, it is also necessary to spray water on the branches and leaves 2-3 times a day and sprinkle water on the ground around the flower pot to increase air humidity. In autumn, when it enters the flower bud differentiation stage, watering should be reduced, and it is better to keep the potting soil slightly moist. In the peak growing season, apply dilute bean cake water about once every half month. After the Start of Autumn, fertilization should mainly be phosphorus fertilizer, and compound chemical fertilizer can also be applied as a top dressing.Notes on growing flame vine
3. Put it on a trellis in time. Because flame vine has a climbing nature and the plant grows very fast, it needs to be put on a trellis in time. If grown on a balcony, thick iron wire and relatively thick bamboo poles can be used to build a frame of a certain form, and then its stems and vines should be trained onto the flower trellis and distributed evenly. When flowering, strings of bright flowers hang all over the trellis, and people like them very much. Flame vine is not cold-tolerant; in northern regions it needs to be brought indoors to overwinter after the beginning of winter.
How to propagate flame vine
Flame vine can be propagated by layering or cuttings. Layering propagation of flame vine can be carried out in spring or summer; roots begin to form in about 1 month, and in about 3 months it can be separated from the mother plant and transplanted. Cutting propagation is also carried out in spring and summer.
For cuttings in mid-to-late March, choose 1-year-old robust branches as cuttings and insert them into a wet sand bed, spraying to keep moisture. When the air humidity stabilizes at around 20°C, roots form about 25 days after cutting, and the survival rate can reach 70%. After about 1.5 months, they can be moved to a nursery for cultivation. One-year-old seedlings can be shipped out for planting, can bloom the following year, and in the third year can achieve a landscaped scene. Old stems can also be used for cuttings, that is, selecting robust old stems sprouting from the base, which can reach more than 2 m in length, and inserting them into fertile sandy loam, keeping them in half shade; roots begin to form in about 50-60 days, and in that year let them grow branches and leaves freely.Cultivation methods for flame vine
Layering mainly uses vines that have fallen to the ground, wounding the bark at the leaf axil and covering it with soil. It can be done from spring to autumn, with summer being the most suitable. Roots form in half a month to one month, and in about 1.5 months it can be cut off as a new plant, which can bloom in the same year. It is mostly grown as a potted flower, or layered directly into a container without moving it to a nursery for seedling cultivation.
Conclusion: Whenever flame vine blooms, dotted here and there and brilliantly red, it makes people feel extremely festive. I hope the above information on how to plant flame vine and the cultivation methods for flame vine can be helpful to you. That is all for today.
