Camellia colonization is generally carried out before the germination of Camellia from February to April in spring; it is suitable for the autumn to be carried out in the dormant period after the leaves, and is planted in pots to facilitate wintering into the greenhouse or into the greenhouse for wintering. When planting, first cover the three water seepage holes under the flower pot with tiles, put the nutrient soil, put the half pot, and after compaction, turn the nutrition of the seedlings upside down, then use the wooden stick or the finger slowly. Slowly connect the soil seedlings together, then move them into the pots, then fill the pots, fill the soil 2 cm from the basin, compact the pots, pour water, and put them into the shade of the room, after 3 to 5 weeks. Move out of the house and keep the soil moist.
Potted camellia can't make it grow too high, generally it is suitable to control about 1 meter. After the potted plants are planted on the pot, they start to grow mainly in vegetative growth, and the top buds grow continuously. Generally, no trimming is required. It is necessary to pay attention to the main shoots to promote the branches and promote the branches, and the dwarf canopy is suitable.
Potted camellia is mainly used for heart-shaped trimming. The pruning of middle-aged plants mainly includes spring shears and summer shears. Spring shears are usually carried out before spring germination. Summer shear refers to the pruning in the growing season, mainly to cut off the dead branches, cross branches, long branches and diseased branches, and should be done in time to pick up the heart and wipe out the sprouts. The pruning of old plants should be carried out by means of short cuts, thinning, and pulling branches to achieve the purpose of renewal.
Watering is the key to the success of potted camellia. After 4~5 months, the temperature rises, the camellia grows rapidly, and the water demand increases. In addition to keeping the soil moist, it should also spray water around it to maintain a certain environmental humidity. Decline, the amount of water can be slowly reduced; in winter, the plants go to sleep, the potting soil can maintain 30% humidity, prevent over-wet, too dry, so as to avoid rotten roots or plants withered. The watering of potted camellia should also be flexibly controlled according to the specific conditions of the plants. Small plants should be poured less and larger plants should be poured more.
Potted Camellia topdressing can be divided into three different stages in a year: First, during the spring equinox to the mango species, potassium dihydrogen phosphate is used as the root outer surface spray fertilizer once every 7 days, in order to enhance the tree potential. The second is that during the period of the great summer, it is the flowering period, and the fertilizer is sprayed once every 2 days. The purpose is to make the camellia flower more. The third is to apply potassium dihydrogen phosphate fertilizer once during the period of white dew to frost, in order to promote flower bud differentiation.
After planting, about 25 grams of compound fertilizer can be placed in each pot, which can be infiltrated into the potting soil with watering. Usually observe the growth of camellia, and can lengthen or shorten the time of topdressing as needed. If it is found that the Camellia seedlings are not prosperous and lack trace elements, some foliar fertilizers and trace element fertilizers may be sprayed for subsidies. Foliar fertilizers are generally selected from Spray Shibao, Yebianbao, and Qifeng. The newly marketed foliar fertilizer must be used in large areas after a small area test to prevent phytotoxicity; the trace element fertilizer is generally selected from the sulfuric acid type, which can increase the absorption rate of camellia. According to the actual situation of lack of trace elements, It is preferred to use zinc sulfate, ferrous sulfate, magnesium sulfate, and the like.
Camellia often has yellowish or greenish leaves. It can be sprayed with 1:300 times of ferrous sulfate, and sprayed twice a month from March to September, which can prevent it. Insect pests include pests such as red spiders, scale insects and whitefly. It can be controlled with one hundred thousandth of soapy water or 50% of omethoate spray. If the whitefly is seriously harmful, 50 grams of pepper can be used, 500 grams of water can be heated and boiled in the pot, boiled into 250 grams of pepper juice, then the pepper solution is added 6 times of water, sprayed on the leaf surface, sprayed to the front and back of the leaf It is advisable not to drip water. It can also be rotated with the above drugs, and the effect is better. If you really want to introduce it, just pay attention to it.
