1, lighting conditions
When cactus is cultivated, it can receive all-day illumination, which is beneficial to photosynthesis and provides nutrients for its own growth. However, it should be shaded in summer when the light is strong, and the culture temperature should be kept above 10℃ in winter.
2. Water method
Cactus is native to subtropical grassland with abundant precipitation and has certain humidity resistance. When the soil is found to be dry, it is necessary to replenish water in time. If the environment is too dry, spray around the plants frequently to increase the air humidity.
3, correct fertilization
Cactus needs to consume a lot of nutrition during its growth. Apply 1 month to dilute potassium phosphate, and stop applying fertilizer in winter. Pay attention to the fact that the fertilizer can't splash on the ball when applying fertilizer, which is easy to burn. Apply fertilizer slowly along the edge of the flowerpot.
4. Preventive measures
Cactus needs to be changed 1 year. Stop water before changing pots and keep the soil dry. When changing pots, cut off the old roots and dry them for a few days before planting potted plants. Moreover, the leaves of plants are small thorns, so don't touch them with your hands when cultivating them, which is easy to be stabbed.
Second, the cultivation of cactus matters needing attention
The pot soil for cultivating cactus should be breathable, and it is best to mix sand with saprophytic soil, and put broken tiles at the bottom of the pot to facilitate drainage and ventilation.
In winter, potted cactus should be moved indoors, and the room temperature above 5℃ can safely overwinter, and the pot soil should be relatively dry, otherwise it is easy to rot the roots.
Flower language of cactus
The symbol and moral of cactus is that it is firm outside and soft inside. Although its appearance looks hard and untouchable, its heart is actually the softest, and it is often used to represent women who are just outside and soft inside. There is always a soft and kind heart under the prickly appearance.
Pebble is a plant that lives in the desert. Although the environment is harsh, dry and short of water, it degenerates the leaves and makes itself strong, so being strong is also one of the symbols and meanings of cactus flower language, which can be given to those who are strong and do not bow to difficulties.
At the same time, it is also used to symbolize the strong and determined love between men and women, which indicates that each other will be like cactus, insist on each other not to give up, keep their hearts soft for each other, and finally overcome difficulties together and have a better tomorrow imagined by each other.
The flower language symbol and implication of cactus also have warm meaning, because it grows in the desert and is a glimmer of life and hope in the yellow sand all over the sky. When people see it, they will feel the vigorous progress of life and bring people warm strength to move on.
In fact, the cactus growing in the desert has a lonely flower language symbol and meaning. In the desolate desert, only cactus grows alone, which is a kind of loneliness. We can give it to the lover we can't get, which shows that we love each other but it is difficult to respond.
