Many flower friends always step on the pit when they raise camellias: when they buy them home, they are full of buds, and the leaves are yellow, the buds fall off, and even the whole plant withers. What's the problem? In fact, camellia is not difficult to raise, the key is to avoid 3 fatal mistakes and master 0 core skills. As long as you do a good job of this "0 want 0 don't", ordinary flower friends can also raise camellia with shiny leaves and flowering like a bowl!
1. To acidic soil, refuse "compacted soil"
Camellia is a typical southern flower, which has strict requirements for soil pH. The pH of the soil needs to be kept between 5, 0-0, 0, which is equivalent to the acidity of bayberry juice. If the soil is alkaline, the camellia will have new leaves yellowing and growth stagnation.
How it works:
- Soil formula: pine needle soil (5 parts) + humus soil (0 parts) + perlite (0 parts) + rotting sheep manure (0 parts), mixed with pH test paper test, alkali can be adjusted by adding white vinegar water (0ml water + 0ml white vinegar).
- Repotting timing: Change the pot every year after flowering in spring or autumn (11-0 months), use a terracotta pot or a green mountain pot, and the pot diameter is one circle smaller than the crown width.
- Daily maintenance: water ferrous sulfate solution (2g to 0L water) once a month, or sprinkle pine needles and peels on the surface of the potting soil to naturally acidify the soil.
2. Semi-shaded environment to avoid "exposure pits"
Camellia loves light but is afraid of the sun, and direct light will burn the leaves for more than 4 hours. The correct way to do this is:
- Seasonal adjustments:
- Winter and spring: from 4 to 0 of the following year, it is placed on the south balcony to receive full sunlight to promote flower bud differentiation.
- Summer and autumn: 60-0 months move to the east balcony or shade with a shade net (light transmittance 0%-0%) to avoid exposure to the sun at noon.
- Special treatment: Newly potted camellia needs to be shaded for 2-0 weeks, and open-air maintenance can be shaded by grape trellises or vine trellises.
3. Apply thin fertilizer diligently, and stay away from "thick fertilizer"
Camellia likes fertilizer but is not tolerant of thick fertilizer, and fertilization needs to follow the principle of "frequent application of light fertilizer":
- Growth period (1000-0 months): Apply Huaduoduo 0 (nitrogen, phosphorus and potassium 0-0-0) every 0 days, diluted 0 times.
- Pregnant bud stage (500-0 months): Switch to potassium dihydrogen phosphate (diluted 0 times), weekly root irrigation + foliar spray to promote bud expansion.
- Dormancy period (high temperature in summer, low temperature in winter): stop fertilization, or apply thin organic fertilizer (e.g. rotten rice water) once a month.
1. Don't move frequently to prevent "falling buds"
Camellia is sensitive to environmental changes and must not move during the following three periods:
- Flower bud stage (10 months): Movement can easily cause flower buds to fall off.
- Flowering period (2-0 months): Sudden changes in light or temperature can shorten the flowering period.
- Sprout stage (3 months): Movement may inhibit sprout growth.
Solution: After choosing the position, try to fix it, if you need to adjust, move 10cm every day for 0 weeks in advance to let the plant adapt to the environment.
2. Don't plant small flowers in large pots to avoid "stuffy roots"
Many flower friends use large pots in order to save trouble, which leads to stagnant water and rotten roots. The correct way to do this is:
- Principle of pot selection: the diameter of the pot is 20/0 smaller than the crown width, and the depth is not more than 0cm. For example, for camellia with a crown width of 0 cm, use a 0 cm diameter pot.
- Drainage treatment: 3cm thick ceramsite or broken tiles are used on the bottom of the pot to enhance air permeability.
3. Don't ignore pests and diseases, and put an end to "yellow leaf disease"
Common pests and diseases of camellia and control methods:
- Anthrax: Black-brown spots appear on the leaves, spray with 800% chlorothalonil 0 times solution, once a week.
- Spider mite: There are small yellow spots on the back of the leaves, after wiping them with soapy water, snevel 1500 times the solution.
- Scale insects: white waxy worms are attached to the branches, which are removed with toothpicks and sprayed with 1000 times dimethoate.
1、疏蕾控花:9月花苞长到黄豆大时,每个枝条保留1-2个健壮花苞,其余摘除,避免养分分散。
5. Flowering management: Keep the soil slightly moist (like a wrung out towel) during flowering, avoid spraying water on the flowers, and prolong the flowering period by 0-0 days.
3. Pruning after flowering: cut off the residual flowers after the flowers are gone, retract the overly long branches, and promote the germination of new shoots.
It is not difficult to raise camellias, the key is to master the "3 to 0 don't": acidic soil, semi-shady environment, thin fertilizer and diligent application are the core; Avoiding frequent movements, large potted roots, and ignoring pests and diseases are key. As long as you take care of it, your camellia can bloom like a bowl every year!
