How to maintain lily roses in winter?

The lilies and roses of the florist are maintained like this in winter:

Influence lilies. The main factor in the flowering period of roses is: temperature.

Humidity. Bacteria multiply. Usually on Valentine's Day, the temperature is generally low, so it is not very important.

Low humidity will affect the color of the flowers, and it is not very important. Relatively speaking, the reproduction of bacteria is the ultimate factor affecting the flowering period of flowers, too many bacteria will affect the absorption of water by flowers, resulting in soft heads of roses and discoloration of lilies. Reducing the reproduction of bacteria will increase the flowering period of flowers, and the way to reduce bacterial reproduction is to add preservatives, but increase the cost.

At present, the best preservative is Yunnan Colorful Flowers** "Kelixian" rose preservative, 600 yuan per bottle, 1 liter. The easy way is to wash the bucket once a day, then wash the stems, add a little sugar to the water, and cut the stalks of the flowers every two days. Usually at room temperature 12 degrees.

The humidity is 75% or more. Roses should bloom for at least 18 days. Lily 23 days 3 heads.

Whether it is white lily or golden lily, it has the characteristics of cold resistance, light liacity, fertilizer resistance, and moisture tolerance, and the suitable temperature for growth is 12 18. In winter, even if the temperature drops to 3 5, it will not die of cold. If there is a lack of sunlight, prolonged shade can affect normal flowering.

However, they have a wide range of adaptability to the region, and can be planted or potted in various places in the north and south. Because it is a bulbous plant, it can be sown directly with the seed head, and it is required to sow to a depth of six or seven centimeters, so that the lateral roots can be deeply rooted and absorb as many nutrients as possible. The required planting material is better for sandy loam, not clay and limestone.

If you use pond mud for planting, you should also mix some river sand and charcoal crushed to make the planting material loose and breathable in order to bloom in time.

For the time being, the seeds of the newly emerging golden lily still have to be imported from abroad**. In the cultivation process, the demand for phosphorus and potassium fertilizer is more, and it is best to use some bone meal, plant ash and peanut drum as base fertilizer before sowing. Appropriate topdressing of chemical nitrogen fertilizer at the time of seedlings will allow them to grow vigorously.

In the south of the Yangtze River, it takes about 120 days for the early-maturing varieties of golden lily to bloom from sowing to flowering. For medium-late maturing varieties, it takes about 15o days. If you want to control the flowering and marketing before the Spring Festival, you must understand the maturity of the purchased varieties in advance, and determine the sowing date due to weather changes to prevent mistakes that cannot be marketed during the season.

After the lily blooms, many people throw away the bulbs. In fact, it still has the ability to regenerate, as long as the residual leaves are cut off, the bulbs in the pot are dug out and buried in a sand pile, often moisturized and not sunned, it can still be planted again the next year, and it is expected that the flowers will bloom twice.

Lilies generally prefer acidic soils with a pH value and humus-rich soils with a bulk density of less than 1 gram cubic centimeter. Avoid flooding, prefer semi-shaded environment, but excessive shading will cause flower stems to grow and flower buds to fall off.

Temperature: The temperature of the roses should not be too low, two or three degrees above zero, in a cool place, do not see the sun.

The petals tend to have black edges after a long flower, so cut them off or remove them with scissors (if there are enough petals). When the leaves of roses and lilies turn black, the flowers and leaves are blown by the wind or cold air when buying, and when buying flowers in the future, you should remember not only to wrap the flowers, but also to wrap the flowers and leaves, preferably with newspapers.

Rational use of water is the key to prolonging the life of flower arrangement. When arranging flowers, you should choose clean, close to room temperature river water, rainwater or pond water. If tap water is used, it must be stored in a tank (barrel) for 1 day before use.

At the same time, it is necessary to pay attention to frequent water changes, remove residual flowers and leaves in time, and appropriately cut short flower branches to facilitate flower water absorption and prolong the life of flowers.

2. Rose Maintenance: Flowers.

1.To prevent the bending of the flower head, the stem base can be cut obliquely, the flowers and leaves can be wrapped in newspaper, and the whole handful can be immersed in water to absorb water.

2.If the head is folded, the base is cut off in warm water and the preserving solution is inserted.

3.In order to prevent bacterial infection of the wound, bleach or preservative should be used to insert it into the bottle for longer life.

4.Sensitive to ethylene, should stay away from overripe fruits (such as bananas, apples), incense, etc., to avoid premature withering.

Three lily maintenance:

1.Spread out the branches to make them breathable, and cut the base 3 5 cm to remove the water, and remove the leaves below the horizontal plane.

2.When the flowers open, the mosaic herbs are removed to avoid accidentally getting on the clothes and are not easy to clean.

3.Adding bleach or preservatives can prolong flowering.

4.However, early flowering can be inserted into warm water.

5.Sensitive to ethylene, need to avoid overripe fruits and vegetables, smoke, incense, etc.

Whether lilies are afraid of freezing.

Lilies are hardy and not afraid of freezing. Its optimal growth temperature is between 15-25 degrees, but the growth below 10 degrees or above 30 degrees is poor, and it should be moved indoors in time throughout the winter maintenance period.

How to maintain lilies in winter.

1.Warmth measuresLily cannot tolerate severe cold and will wither and die at ambient temperatures below 0 degrees. When cultivating lilies in the northern winter season, they need to be moved to a greenhouse in November every year for maintenance.

In the southern winter, lilies can be kept outdoors and wrapped in plastic bags to keep warm. 2.Fertilize.

When the lily successfully overwinters, it is necessary to fertilize the plant at the end of December every year. You can choose well-rotted organic fertilizer or farmhouse fertilizer to improve the cold resistance of the lily. However, if you want to grow lilies in winter, you must first suspend fertilization to avoid fertilizer damage to the plants.

3.Maintain humidity. In winter, raise lilies indoors and do not put them under the radiator to avoid poor growth.

When the environment is too dry, spray water mist around the lily with a watering can to increase the humidity of the air, and wash the lily branches and leaves with clean water to make it more beautiful. 4.When maintaining and managing lilies in winter, it is necessary to treat them with a digging insecticide to avoid pests and diseases infecting lilies.

At the same time, cut off the withered branches and leaves, and move the lilies to a sunny place when spring arrives, so that they can grow healthily.

Precautions for winter cultivation of lilies.

Plenty of sunshine: In winter, we want to keep the lilies in plenty of sunshine. If there is too little sunlight, the buds of the lily will easily fall off, the stem of the lily will grow bigger and bigger, and then the lily will grow white.

Warm Huanqiao scattered environment: In winter, the lily needs to be moved indoors to 15 degrees Celsius for maintenance, and the temperature should be controlled between 15 degrees and 25 degrees, so that the lily can grow vigorously and bloom in winter. Humid environment:

Keep the potting soil moist in winter, otherwise it is not conducive to the growth of lilies, the growth of lily stems, and the flowering of lilies. Proper fertilization: Lily can be fertilized with phosphorus and potassium fertilizer, which can promote flowering.

After the lily grows into a flower stem, nitrogen, phosphorus and potassium compound fertilizer can be applied to the lily at a ratio of 1:1:1 to facilitate the growth and development of the lily.

Lilies are hardy and not afraid of freezing, its optimal growth temperature is between 15 and 25 degrees, but it grows poorly below 10 degrees or above 30 degrees, and should be moved indoors in time for all winter maintenance. In the northern winter, it is moved indoors in a warm place, while in the southern winter, the lilies can be placed outdoors and wrapped in plastic bags to keep warm.

How to maintain lilies in winter.

1. Warm measures

Lilies are not tolerant to severe cold, and will wither and die at ambient temperatures below 0 degrees, when breeding lilies in the northern winter, it is necessary to move the lilies to a warm indoor place in November every year for maintenance, and in the southern winter, you can put the lilies outdoors and wrap them in a plastic bag for heat preservation.

2. Apply fertilizer

Lilies successfully overwinter to the plant at the end of December every year to apply fertilizer, you can choose well-rotted organic fertilizer or farm fertilizer, in order to improve the cold tolerance of lilies, but to breed lilies in winter, you must first postpone fertilization on the plants, so as not to cause fertilizer damage to the plants.

3. Maintain humidity

When raising lilies indoors in winter, do not put them under the radiator, so as not to grow poorly, in the case of too dry environment, spray water mist around the lilies with a watering can to increase air humidity, and wash the lily branches and leaves with clean water to make it more beautiful.

4. Maintenance management

When maintaining lilies in winter, it needs to be treated with a one-time insecticide to avoid pests and diseases that infect lilies, and at the same time, the yellow branches and leaves and withered residual flowers should be cut off, and after the arrival of spring, the lilies should be moved to a sunny place to make them grow healthily.

Precautions for winter cultivation of lilies.

Plenty of sunshine:In winter, we should keep the lily in full sunlight, if there is too little light, the buds of the lily are easy to fall, the flower stem will become longer, and the lily will also grow long.

Warm environment:In winter, we need to move the lily indoors at 15 degrees Celsius and control the temperature between 15 degrees and 25 degrees, so that the lilies can grow vigorously and bloom in winter.

Humid environment:Keep the potting soil moist in winter, otherwise it is not conducive to the growth of lilies, nor is it conducive to the growth of lily stems, and even more so to the flowering of lilies.

Proper fertilization:Phosphorus and potassium fertilizers can be applied to lilies, which can promote flowering. After the lily grows into a flower stem, nitrogen, phosphorus and potassium compound fertilizer can be applied to 1:

A ratio of 1:1 is applied to lilies to facilitate the growth and development of lilies.

1. New line lily: If you have a cellar at home, you can put fresh lilies in the cellar, which can be kept for about 3 months without deterioration. You can also put the fresh lilies in a ventilated place, spray some fruit preservative, or wash and drain the fresh lilies, put them in a fresh-keeping bag, and store them in the refrigerator.

2. Dried lily: Prepare a clean and dry jar, put the dried lily in it and seal it with a sealed sail for preservation, and then put it in a ventilated and cool dry place or refrigerator. Do not touch the water to avoid moisture when the hail is stored.

3. Soil preservation method: Pack the lily in a plastic bag, pump it into a vacuum, and then put it in a solid plastic box, bury the box in the soil, and it can be stored for 3 weeks to 1 month.
