The reasons and methods of the latest longevity flowers not blooming

The longevity flower gets its name because of its long florescence as a whole. It is famous for its easy cultivation and is becoming more and more popular with the gradual enrichment of varieties, but the longevity flowers raised by many friends do not bloom. Let's take a look at the reasons why longevity flowers do not bloom and how to make longevity flowers blossom more.

Longevity flowers bloom several times a year

Longevity flowers prefer warm, moist and sunny environment, and are not resistant to cold. The suitable temperature for growth is 15: 25 ℃. When the high temperature exceeds 30 ℃ in summer, the growth is hindered. The indoor temperature in winter is 12: 15 ℃. Less than 5 ℃, the leaves became red and the florescence was delayed. Flowering in winter and spring will be inhibited if the room temperature is more than 24 ℃. If the temperature is about 15 ℃, the longevity flowers will bloom continuously.

Longevity flowers are resistant to drought and are not strict with the soil, so it is better to use fertile sandy loam. Longevity flowers are short-day plants and are sensitive to photoperiod. For the plants with good growth and development, the buds can blossom after being treated with short-day sunlight (8-9 hours per day) for 3-4 weeks. Therefore, the flowering period of longevity flowers is from December to May of the following year. As long as they are raised well, beautiful flowers will continue to bloom during this period.

The reason why longevity flowers do not bloom

1. Lighting: longevity flowers like a sunny environment, avoid strong light exposure at noon in midsummer, and keep them in the sun for the rest of the time. At least 4 hours of direct light can be seen every day in order to grow healthily. In order to make the longevity flower plant flowers evenly, we should pay attention to often change the direction of the flowerpot, so that the plant balanced to receive light, the building balcony every semimonthly to turn the flowerpot 180 degrees. Although the semi-shade can also grow, but the stem thin leaves thin flowers less light, far less luxuriant than the sunny place. If the shade is not only easy to lose leaves and no flowers, even if the flowering plants are placed in the shade, the flower color will become dim, and then the flowers will fall off and wither.

2. Nutrients: longevity flowers like to be fat. The flowering period of longevity flowers is long, so it is necessary to break the commandment of not applying fertilizer during the flowering period, and apply thin nitrogen, phosphorus and potassium fertilizer or 0.2% potassium dihydrogen phosphate solution once a month, so that the later flowers will not become small and pale due to lack of fertilizer. From the longevity flower frost falling into the house to October of the following year, it happens to be the late differentiation and full flowering stage of the longevity flower bud, so there is a great demand for fertilizer. Fishy fertilizer based on phosphorus and potassium should be applied once a week before flowering to promote flower bud differentiation. The florescence is dominated by the application of quick-acting potassium dihydrogen phosphate, with a concentration of 2%, once every 10 days.

How can longevity flowers bloom more?

1. The flowerpot should not be too large: some flower friends mistakenly think that the bigger the flowerpot, the better the plant grows and the more luxuriantly it blossoms. For this reason, the twigs are planted in large flowerpots that are extremely incongruous in proportion and apply sufficient base fertilizer. They think that if they are "in place at once", they only need to wait for them to blossom. This method is often not effective, the reason is very simple: the flowerpot is large, the space is large, the root system grows and spreads freely, needlessly consumes a lot of nutrients. As a result, the leaves are sparse and narrow, the flowers are few and the flowers are small.

2. Plant type should not be too high: after summer dormancy, autumn is the period of exuberant growth of longevity flowers. Large-scale pruning should be carried out before the Beginning of Autumn to make the plant type low and stout and promote the development of branches. Combined with fertilization, the plant can grow well. Because there are many branches, there will be more flowers in the future.

3. Fertilization should not be too thick: adequate fertilizer and water is the basis for plants to blossom and flourish, but many flower lovers, on the one hand, overestimate the endurance of longevity flowers, and on the other hand, they often apply a large amount of heavy fertilizer at one time, which is counterproductive. Longevity flowers either have a large number of yellow leaves or are listless because of the high concentration of soil solution. Longevity flowers belong to plants that need medium amount of fertilizer, and it is hard to apply thin fertilizer and diligent application at ordinary times. Topdressing should be mainly selected in the bud stage and flowering stage, bone powder and potassium dihydrogen phosphate can be diluted into liquid fertilizer. The bone meal (80g / bag) and potassium dihydrogen phosphate (30g / bag) bought from the flower market are diluted into 1.25L beverage bottles to make liquid fertilizer with about 1/4 or 1/5 respectively. Spraying the leaves with potassium dihydrogen phosphate and watering them with bone powder and potassium dihydrogen phosphate at the same time, the buds will be full of branches.
