How to cultivate longevity flowers all the year round? Conservation of longevity flowers in four seasons

Longevity flowers, perennial succulent herbs, flowering in winter and spring, as long as 4 months. Because the leaves are big and green and the flowers are luxuriant, the flowering season coincides with New Year's Day and the Spring Festival, which is very popular with many families, and longevity flowers have a good meaning of good luck and longevity, so many flower lovers want to raise longevity flowers at home. In fact, it is not difficult to raise longevity flowers. Flower cultivation should first understand the habits of flowers, and master watering, temperature, light, fertilization, and topping, so today, the editor will share how to cultivate longevity flowers all the year round.

Spring

The spring is in the flowering stage, so keep plenty of light.

Lighting: flowering longevity flowers need sufficient light to ensure that the flowers bloom vigorously, maintaining all-day light is necessary, sufficient light can prolong the flowering period. If the weather warms up at the end of spring, reduce the sunshine time appropriately, pay attention to warm maintenance in early spring.

Watering: longevity flowers are afraid of waterlogging, watering would rather be dry than wet. Longevity flowers are succulent plants, which have a lot of water and do not like too much water. When you need watering, you can find a bamboo stick to insert directly into the bottom of the soil. If the soil at the bottom is dry, you need to water it thoroughly at one time.

Summer

Longevity flowers like temperature and fear heat, and summer is mainly shading and cooling.

Light: the most important thing in summer is summer. Avoid direct sunlight, suitable for shady environment, good ventilation.

Watering: water less in summer to avoid flooding. In summer, the surface soil dries quickly, the bottom dries slowly, and more watering is easy to rot the roots.

Autumn

The autumn temperature is suitable, which is the vigorous growth period and bud stage of longevity flowers. Lighting: plenty of light to avoid strong light. Half a day of light in the morning, strong light in the afternoon can be put indoors to maintain growth needs and bud differentiation.

Watering: like spring watering, you'd rather water less than have nothing to do.

Topping: to raise a pot of beautiful longevity flowers, topping in autumn is necessary. Autumn is the peak period of production. On the one hand, topping avoids the waste of nutrients and is conducive to the formation and differentiation of flower buds; on the other hand, it makes the plant short and strong and beautifies the plant type.

Winter

Winter is the flowering season, pay attention to heat preservation and adequate light

Lighting: flowering needs sufficient light, can be placed in a warm balcony all day, receive sufficient light, flowers bloom exuberant, full.

Watering: water less in winter and the soil should be a little dry. Winter temperature is low, water volatilization is slow, keep the soil a little dry, watering only a little bit, wet soil on it.

Temperature: low temperature in winter, need to keep warm. Keep it warm at night in a warmer place, such as in the bedroom.

The longevity flower has phototropism, so it is necessary to adjust the direction of the flowerpot regularly. For example, rotate the flowerpot 90 degrees a week to evenly receive light, and you can place a small stone to mark it in the flowerpot, so as to ensure that the plant does not deviate from the crown and keep it beautiful.

Master the main points of longevity flower maintenance, blossom continuously all the year round

Catharanthus roseus not only has a long flowering period, but also small flowers are very lovely. Catharanthus roseus is also a good medicine, which has excellent effects on pain relief, anti-inflammation and so on. Do you want to buy such a pot of flowers that are both beautiful and effective? Here, the editor has sorted out some key points about the conservation of Catharanthus roseus, which I will share with you.

A warm and humid environment

Catharanthus roseus likes to grow in a warm and humid environment, so plenty of light is necessary. The general temperature is controlled at about 18 degrees Celsius, which can fully meet the growth requirements of Catharanthus roseus. Pay attention to keep warm in winter, and friends in the north should pay special attention to them. Don't put them outdoors at this time. They will also be "unhappy". Many flower lovers say that their Catharanthus roseus has withered in less than a year, but in fact they have not done a good job in winter management. Before winter, Catharanthus roseus will have fallen leaves and yellow leaves, but it doesn't matter. It doesn't mean it's going to die. Don't throw it away. It will return to its original appearance next spring.

Loose and fertile acidic soil

Although Catharanthus roseus does not have high requirements for soil, it will also affect its growth if the salinity of the soil is too high. It is best to choose some humus soil, which is generally good in ventilation and drainage, which is conducive to the growth of Catharanthus roseus.

Watering should be strictly controlled.

Catharanthus roseus is not resistant to waterlogging, so it must not be watered too much. In summer, the temperature is relatively high and the air is relatively dry, so you can pour a little more water appropriately. Water less in winter and maintain a certain degree of dryness, otherwise it is easy to freeze.

It is necessary to apply fertilizer alternately

In the growth stage of Catharanthus roseus, fertilizer can be applied every 10 days or so, preferably alternately compound fertilizer and liquid fertilizer, which is beneficial to the bud gestation of Catharanthus roseus. In winter, fertilize as little as possible, and it is OK not to apply fertilizer.

Necessary pruning

Catharanthus roseus is a kind of potted plant, which can not grow too high, which will affect its beauty. So be sure to trim it. Generally speaking, the method of picking the heart is used, so that Catharanthus roseus can grow more branches and bloom a little more. For some residual flowers, diseased flowers should also be pruned in time, otherwise it will cause nutrient loss. Florists in the north can trim their branches to about 20 centimeters when the temperature drops slowly, so that they can save more nutrients during the dormant period, and more flowers will bloom in the coming year.

Summary of maintenance points of Catharanthus roseus

1. Plenty of light

2. Enough fertilizer

3. Moderate pruning

4. Warm environment

Longevity flower culture methods and matters needing attention to help you cultivate longevity flowers

Longevity flowers prefer a warm, slightly moist, sunny environment. The suitable temperature for growth is 15-25 degrees. When the temperature is higher than 30 degrees, the growth is blocked, when the temperature is lower than 10 degrees, the growth stops, and when the temperature is lower than 5 degrees, the leaves turn red (different varieties have different sensitivity to low temperature). Longevity flowers need sufficient light, if the light is not enough, it is easy to cause overgrowth of plants, resulting in thin branches, thin leaves, reduced number of flowers and not bright flowers.

Methods of longevity flower culture 1. Soil selection of longevity flower culture

Longevity flowers should not be cultivated in clayey soil, otherwise it will lead to poor growth, rotten roots and leaves, and in serious cases, plant death. The basin soil was mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand, plus a small amount of bone powder. This kind of cultivated soil is loose and fertile, has good drainage performance, and shows a slightly acidic reaction, which is beneficial to the development of root system.

2. Fertilization method

Longevity flowers should not be cultivated in clayey soil, otherwise it will lead to poor growth, rotten roots and leaves, and in serious cases, plant death. The basin soil was mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand, plus a small amount of bone powder. This kind of cultivated soil is loose and fertile, has good drainage performance, and shows a slightly acidic reaction, which is beneficial to the development of root system.

In the peak growing season, thin compound liquid fertilizer can be applied every 15 to 20 days to promote robust growth and luxuriant flowering. If 0.2% potassium dihydrogen phosphate or 0.5% superphosphate is applied twice after flower bud formation in November, the flowers will be more, the color will be bright, and the florescence will be long.

3. Watering method

Longevity flowers, like other succulent flowers, contain more water and have a strong ability to resist drought, so they do not need a lot of watering. During the growth period, as long as every 2-3 days to water once, keep the basin soil slightly moist. Watering should be controlled when the temperature is low in winter. If the watering is too much, the drainage is not smooth, and the basin soil is too wet, it is easy to cause root rot.

Although longevity flowers are more drought-tolerant, they can not be short of water in the growing season and can be watered every 2-3 days. In the stage of vegetative growth, the soil must be kept moist and watered at the right time. In summer, longevity flowers can be watered once a day in the environment of high temperature, strong sunshine, large evaporation and dry air. Cold winter, longevity flowers into the dormant period, it should be controlled watering, or even not watered for a short time.

4. Lighting requirements

Longevity flowers like plenty of sunshine, and family training should be placed in places with direct sunlight all the year round. In the northern hot summer season, the light intensity is large, which is easy to make the leaf color yellow, so it is appropriate to shade properly around noon, or put it in the half-shaded part of the room, but pay attention to ventilation and cooling. Long-term cultivation of longevity flowers, if the long-term lack of light, not only slender branches, leaves thin and small, affecting the plant shape beautiful, but also reduce the number of flowers, flowers are not bright, but also cause a large number of leaves to fall off, the loss of ornamental value.

5. Temperature requirements:

The most suitable temperature for longevity flower growth is 20-25 ℃. More than 30 ℃ or less than 10 ℃, it obviously stopped growing and entered a dormant or semi-dormant state. In winter, if the temperature is lower than 10 ℃, move into the greenhouse to survive the winter. If there are conditions, the indoor temperature can be controlled at 16: 20 ℃ during the day and 10: 15 ℃ at night, so that longevity flowers can blossom on New year's Day and Spring Festival.

Matters needing attention in longevity flower culture

The room temperature in winter should not be lower than 12 ℃. It is better to use 15: 18 ℃ in daytime and more than 10 ℃ at night. If the temperature is as low as 6: 8 ℃, the leaves will turn red and the flowering period will be delayed.

1. The longevity flower has phototropism, so during the growth period, attention should be paid to changing the direction of the flowerpot, adjusting the light, making the plant receive light evenly, and promoting the development of branches to all sides. If you do not turn the pot for a long time, the plant will grow on one side and affect the ornamental effect.

2. When it is hot in summer, it should be properly shaded around noon, and ensure ventilation and cooling. If you can not accept sufficient sunlight for a long time, the branches will become weak, the flowers will be dim and the flowers will wither, and the leaves will soften and fall off and affect the ornamental.

3. The ambient temperature should be maintained above 12 ℃. If the temperature is too low, the edge of the leaf will turn red and the flowering will be delayed.

4. Longevity flower is a kind of short-day flower, which can differentiate only when the temperature is 20 ℃ and the sunshine is 8 hours. After the flower bud is formed, according to the light demand of the plant blossom, let it receive scattered light before 10:00 and after 4pm every day in summer, avoid the strong sun at noon, and cover 40% of the light with a sunshade net. Try to keep it under fluorescent lamps at night, so that summer can continue to bloom. During the growing period, in addition to shading in the middle of summer, it is also necessary to maintain a light transmittance of 60%, and give sufficient light in other seasons.

5. Longevity flowers usually change pots from September to October. The basin soil is mixed with peat, vermiculite and garden soil at 2:2:1. After changing the basin, gradually increase the light, and begin to topdressing.

6. Pest control

The most common pests of longevity flowers are aphids and shell insects. Prevention and treatment is the key to these two diseases, and the incidence of these two diseases will be much less in a general ventilated environment. In addition, there is another kind of leaf miner larva, which likes to drill into the leaves, and the mesophyll is almost finished by the time it is found. At present, I have not heard of the effective treatment, usually pay more attention to the back of the leaves, it is better to find the eggs as soon as possible. When you find a moth nearby, you can spray insecticidal medicine immediately. In addition, carbofuran can be sprinkled on the surface of the flowerpot, and the plant will poison the worm after absorbing the solution. But please proceed with caution. Huanshen, dimethoate, imidacloprid, paraquat and so on all have effects on these three kinds of diseases and insect pests.

Propagation of longevity flowers

Longevity flowers are mostly cuttings, and they can also be propagated by sowing and tissue culture.

1. Longevity flower cutting propagation: longevity flower has strong root ability, and cutting propagation is easy to survive. The appropriate time is from March to May in spring, from August to September in late summer and early autumn, if there is a greenhouse, it can be carried out all year round. A suitable wooden box can be used as a cutting nursery bed and strictly cleaned and sterilized before use. The matrix can be loaded into the seedbed with perlite, vermiculite and peat. Select a slightly mature fleshy stem, cut it 5cm long, insert it into the seedbed, cover it with film after watering, keep it for 15-20 ℃, take root for 15-18 days, and transplant after a month.

2. Sowing and propagation of longevity flowers: varieties with basically the same plant type, flower pattern and flower color should be selected for artificial pollination. After harvest, the seeds can be sown in spring and autumn. The nursery bed can be made in a wooden case, soaked and washed with clean water before use, and then soaked in 0.1% potassium permanganate for 10 minutes and 15 minutes. The matrix can be made of 4 parts of rotten leaf soil and 4 parts of pastoral soil plus 2 parts of humus soil, fully mixed, accumulated and cooked, then dug up and screened after exposure, high-temperature disinfection before use, loaded into the sowing wooden box, compacted the soil, scraped the surface, the seeds were evenly scattered in the seedbed, covered with fine soil so that the seeds could not be seen, gently pressed with wood after sowing, and placed the seedling bed in the flume until the whole matrix permeated with water. Then cover the seedbed with a thin film and place it in a warm, shaded and ventilated place for the seeds to germinate. After sowing, the soil should be kept moist, the water should be supplied evenly, the seeds should not be dehydrated, and the temperature of the seedbed should be controlled at about 20 ℃. The film can be opened and covered for a few minutes in the morning and evening to make it ventilated and ventilated. It usually takes 12 to 15 days to grow new buds. At this time, to remove the film, weak sunlight exposure, after a period of time, can gradually increase the light, after the emergence of real leaves, with 0.05% potassium dihydrogen phosphate irrigated to promote the healthy growth of seedlings. After 2 or 3 true leaves are grown, the seedlings sown in spring can be transplanted in summer, and the seedlings sown in autumn can be transplanted before winter and maintained in the greenhouse.
