How to cultivate longevity flowers, how to cultivate longevity flowers

Planting. Plant in the spring or repot and change the soil. The southern region can be planted in the ground, overwintering in the open field, and the northern region should be potted and wintering indoors

Ground planting should be planted in a sunny place, slightly higher terrain, and easy drainage, and the soil should be loose sandy loam. The potting soil is made of fertile sandy loam soil, and the ratio of humus, coarse sand, and chaff charcoal is 2:2

1。When planting, the bottom of the pot should be padded with tiles, and the well-rotted organic fertilizer should be mixed with the cultivation soil as base fertilizer. You can't water it immediately after planting, you need to stop watering for a few days to avoid root rot.

Light and temperature.

Longevity flowers are short-day plants, which do not have strict light requirements, and can grow well under full sunshine, half-day and scattered light conditions. The suitable growth temperature is 15-25. When it is hot in summer, pay attention to ventilation, shade, and avoid strong direct sunlight.

In winter, when entering the greenhouse or putting it indoors to the sun, the temperature should be kept above 10, and the minimum temperature should not be lower than 5, and the leaves are easy to turn red when the temperature is low. Well-developed plants are treated with short days (8-9 hours of light per day, the rest of the day is shaded, and buds can be formed in 20-30 days).

Watering and fertilizing.

Longevity flowers are succulent plants with a lot of water in their bodies and are relatively drought tolerant. Do not water too much during the growing period, water once every 2-3 days, and the potting soil should be moist and preferred. If the potting soil is too warm, it is easy to cause root rot.

Watering master the principle of "seeing dry and wet, and watering thoroughly". Watering should be reduced and fertilization should be stopped in winter. Phosphorus-rich thin liquid fertilizer is applied monthly during the growing season, during the peak growing season in spring and autumn and after flowering.

Maintenance. After potting, it grows more vigorously in a slightly humid environment, and pale red aerial roots continue to grow between nodes. Too dry or too low temperature, growth slows down, leaves turn red, and flowering is delayed.

In midsummer, it is necessary to control watering, pay attention to ventilation, if the temperature is high and humid, the leaves are easy to rot and fall off. Fertilization is applied once every half month during the growing season, and it can also be used"Hui Branch"15 15 30 potted flower special fertilizer. In order to control the height of the plant, it is necessary to carry out 1 2 topping to promote more branching and more flowering.

Longevity flowers are sprayed 1 time with 0 2% ratio 2 weeks after planting, and the plant height is 12 cm and sprayed 1 time. In this way, the height of the plant can be effectively controlled, and the effect of plant beauty, leaf green, and more flowers can be achieved. In the process of flower bud formation in autumn, phosphorus and potassium fertilizer can be increased 1 2 times.

Branches can be cuttings, leaves can also be, my pot is my one leaf raised, the growth is quite good, but the growth is relatively slow.

The cultivation method of longevity flowers is to control temperature, sunlight, moisture, fertilizers, diseases and pests, as follows:

1. Growth temperature

The most suitable temperature for the growth of longevity flowers is 15 to 25, above 30 growth retardation and semi-dormancy, below 10 growth stagnation, below 8 leaf color red, delayed flowering, below 0 is easy to freeze to death. Therefore, to raise longevity flowers, it is necessary to create a small environment that is warm in winter and cool in summer, and at noon in midsummer, it is necessary to avoid strong light exposure, and place it in a semi-shaded place with sufficient scattered light, such as under a big tree, under the eaves or a north-facing balcony, special attention should be paid to ventilation and cooling, and water can be sprinkled on the ground nearby, but not on the plants.

2. Plenty of sunshine

Longevity flowers like a sunny environment, except for a little shade at noon in midsummer, the rest of the time should be placed in a sunny place, at least 4 hours a day to see more than 4 hours of direct light to grow robustly. The balcony of the building should rotate the flower pot 180 degrees every half month to make it evenly lighted, avoid biasing the crown, and reduce the ornamental value. Although it can also grow in the semi-shade, the stems are thin and the leaves are thin, the flowers are few and the color is light, and it is far less lush than the sunny place.

If it is too shady, it is not only easy to lose the leaves and no flowers, but also if the flowering plants are placed in the shade, the flower color will become dull, and then the flowers will fall off and wither.

3. Suitable moisture

Longevity flowers are succulent plants, which contain more water in the body, so they are more resistant to drought and waterlogging, and grow well under the condition of dry air in high-rise buildings. In spring and autumn, about 3 days after seeing the potting soil dry, water it once and keep it slightly moist. In summer, it is advisable to water less, 5 days to 7 days to water once as well, placed outdoors for longevity flowers, rainy season to avoid rain, water is easy to rot roots and fall leaves and even die, proper water control potting soil to see dry and wet, then the branches and leaves are more than flowers.

After entering the room in winter, it is advisable to water at noon with water similar to the room temperature, and once a week or so.

4. Sufficient fertilizer

Longevity flowers like fertilizer, seedlings can be potted for half a month or old plants can be applied 2 to 3 times of nitrogen-based liquid fertilizer to promote the growth of stems and leaves, and after flowering, nitrogen-based liquid fertilizer can be applied once to promote its rejuvenation. The rest of the time except for the summer stoppage, can only apply nitrogen, phosphorus and potassium compound fertilizer, do not make fertilizer on the leaves when fertilizing, otherwise the leaves are perishable, if you accidentally stain the leaves, you should wash off with water.

5. Beware of pests and diseases

With the improvement of environmental mildness, which also leads to longevity flowers are easy to suffer from pests and diseases, pay attention to keep indoor ventilation, prevent pests and diseases from entering the room, but also mainly use some insecticides to prevent the infection of pests and diseases, see the main diseases are downy mildew and anthracnose.

1. Soil.

Longevity is meaty, and it can grow on any soil. But based on my personal experience, it is best to grow on loose, breathable and well-drained soil. The soil I use is:

5 parts of black mountain soil, 3 parts of peat, 2 parts of blue stone (can also be volcanic stone, ceramsite, etc., the particles should be slightly smaller).

2. Fertilizer. Longevity does not have high requirements for fertilizer, and I generally apply base fertilizer when planting, and no longer fertilize at other times. I generally use bone meal for base fertilizer, and when the bone meal is broken, I use granular chicken manure (crushed), and the dosage is half of the grass flowers of the same caliber. That is to say, 20 cm of grass and flower bottom fertilizer to grasp two handfuls, longevity is enough, in the later planting top dressing process can be applied to some flowers and plants commonly used German I type new land water-soluble fertilizer to supplement nutrients and trace elements, half a month fertilization can be.

3. Environment. Except in winter, when it is below 0 degrees, I move my longevity into the sunroom, and at other times let it be exposed to the wind and sun on the terrace. It is said on the Internet that longevity in summer cannot be exposed to the sun, but as far as my personal breeding experience is concerned, longevity is not afraid of exposure.

Fourth, moisture. Longevity is more drought-tolerant and afraid of waterlogging, so even in summer, I don't need to water every day, I usually water the potting soil completely white and dry, like this season, it doesn't matter if you don't water for a month. In winter, it is necessary to water less, even when the flowers are very bright, it is necessary to water the potting soil completely white before watering.

5. Pruning for longevity.

Every year, after the flower failure, it is overhauled, and only about 3 cm of branches need to be left before July, and the rest can be cut off completely (no leaves can be left at all). When pruning, it is necessary to cooperate with repotting and fertilization, and the pruned branches can be cuttings. Soon the longevity will produce a lot of shoots, and then keep the plant within 10-15 cm, and the excess can be removed.

Do not prune again after the end of September, because longevity begins to breed and is ready to flower.

Kalancho prefers warm, slightly moist and sunny environments. It is not cold-tolerant, the growth temperature is 15 25, the high temperature in summer is more than 30, the growth is stunted, and the indoor temperature in winter needs to be 12 15. Below 5, the leaves are red and the flowering period is delayed.

In winter and spring, if the room temperature exceeds 24, it will inhibit flowering, such as the temperature is about 15, and the longevity flowers will continue to bloom. Longevity flowers are drought tolerant, do not have strict requirements for soil, and are preferable to fertile sandy loam soil. Longevity flowers are short-day plants and are sensitive to photoperiod responses.

Plants with good growth and development can appear with flower buds and flowering after 3 to 4 weeks of short day (8 to 9 hours of light per day).
