2. Anti-boredom. As a result, there are not many leaves left, so the water can't evaporate, the roots and leaves can't circulate, the newly-grown water-absorbing white roots are broken, and the buds on them are still growing. When the water can't stand it, it will suffocate and dry. Dry-wet cycle is slow, and material exchange (some substances produced by leaf respiration and photosynthesis) can't cause suffocation through polished rod or weather.
Therefore, the management depends on the weather and seedling conditions, and the targeted management should be adjusted appropriately. If there are too few leaves, be sure to control water, enhance ventilation, do not water the roots for three centimeters, and water the roots with strong rooting powder to promote the vitality of the roots. Rooting powder can prevent dead pots, changing pots, sick seedlings and acclimatization. Apply it once before the four seasons change, which can enhance the disease resistance.
3, antibacterial. White powder, black spots and mold can be killed and prevented by spraying authentic rice vinegar on leaves, stems and soil after rain or when the temperature rises or the humidity returns in the south. Roses are acidophilic plants, and increasing acidity can improve disease resistance. Rice vinegar is also rich in basic amino acids, sugars, organic acids, vitamin B 1, vitamin B2, vitamin C, inorganic salts and minerals.
