Camellia is also known as camellia, belongs to a variety of plants and horticultural varieties of the general term, camellia because of the variety and good, beautiful posture, flower type colorful, and most of the gardening flowers favored. The flowering period of camellia is generally from December to March of the following year, and the time from budding to pregnant flowering is relatively long, so in the flowering period we must take good care of the camellia, if the care is improper in the maintenance process, such as too low temperature, improper watering, insufficient light and disease and insect hazards, it will lead to camellia buds not flowering, and even buds. There are two common non-flowering phenomena, one is that there are flower buds but do not flower or directly fall buds, and the second is that the roots do not even have the opportunity to contain buds to be released.
If the first kind of camellia has the phenomenon of not opening the buds, it may first be due to the problem of temperature discomfort, and the suitable temperature of the camellia bud stage is 10-15 ° C. In the early spring of winter, cold waves are frequent, and when the temperature suddenly drops below 5 °C, it will affect growth and flowering. Therefore, in winter, camellias must pay attention to antifreeze measures, and transplant it indoors when the temperature drops sharply at night, or artificial heating to ensure that it survives the winter safely. Flowers should be placed in a warm place without wind and sunshine during the day. We can also put plastic film bags on the pots during the budding period to raise the temperature.
Camellias maintain humidity during the budding period. In winter and spring, after 10:00 a.m. on a sunny day, the camellias should be sprayed with water mist to maintain air humidity. Specific method If we are potted camellias, we generally water them every three days on sunny days, keeping the pot surface moist, not too dry or too wet. Similarly, if you use a plastic bag to put it on the pot of the camellia, you can also maintain the humidity required for the growth of the camellia.
The main insect pests in the camellia bud stage are aphids and rusty ticks. Pay attention to prevention and control, otherwise it will also lead to the phenomenon of camellia buds and figs, aphids can be sprayed with 40% oxidized Leguo emulsion 1000 times liquid, rust ticks can be used with 50 grams of laundry detergent, 10 ml of diesel fuel and 10 liters of water stirred evenly spray prevention.
The second type is when camellias are directly infertile buds, then it is likely to be soil or nutrient-related reasons. Although camellia flowers prefer slightly acidic soils, if the soil acidity is too high or too alkaline, it will lead to poor growth of camellia flowers and lead to non-flowering, and the normal pH value of weakly acidic soils is between 5-6. If the soil is too acidic we can add lime water, and the alkali can be added to the vinegar method to ensure that the pH of the soil is appropriate.
Camellias in the peak season, especially the flowering season need more water and liquid fertilizer, if the water and nutrients are insufficient will also lead to no flowering and flowering, but over-fertilization or thick fertilizer will also lead to camellia leaves and no flowering. Therefore, during the flowering period, we can ensure the supply of water and nutrients to camellias by mixing water with liquid fertilizer. Specifically, we can use the purchased flower fertilizer (vegetable weeds) and 15 ml of water diluted with 1 L of water to water the roots and spray on the leaf surface. To ensure nutrition and promote flowering, vegetables can promote strong buds, enlarged petals and prolonged flowering period.
In order to flower normally, the entire growth period should pay attention to the control of insect pests and diseases, and the main insect pests of camellia are borer stem insects and mesenchymal insects. The main bacteria are anthrax, black mold, etc., so in addition to preparing special flower fertilizer, there should also be special insecticidal sterilization drugs.
In addition to the above several coping methods, camellia should also do some necessary pruning, especially when there are too many buds, cut off the weak branches on the top and sort out the buds, so as to ensure the reasonable and sufficient absorption of nutrients during the flowering period and promote the flowering effect of the camellia flowers.
