Potted flowers watering tips
Watering potted flowers at right time, because of the limited volume of pots, the water content of pots and soils is correspondingly less, and at the same time there is no groundwater supplement, so it is not tolerant to drought, and timely watering is especially important. When potted plants are to be watered, they can be judged by listening, seeing colors, and pinching soils. Use your finger to flick the flowerpot, such as boring dull sound, indicating that the basin soil is moist, without watering; such as issuing a crisp sound, indicating that basin soil is dry, need watering. Look at the color of the basin soil. If it is gray, it means that the soil is dry and needs to be watered; if it is dark, it means that the soil is moist and does not need to be watered. Hand-picked pots and soil, such as a group, that the soil is moist, no watering; if it is powdery, it means that the soil is dry and must be watered. Potted potted flowers should be based on their flower species, soil, climate, season, plant growth status, and their environment to determine the time, number of times and watering watering, so as to achieve adequate watering, in order to promote flower growth. Wet flowers (such as ferns, tropical orchids) should be watered more, and horticultural flowers (such as cacti and agave) should be watered less; herbaceous flowers should be more watery than woody flowers; leaves large and soft The smooth, hairless flowers are more watery than the leaves with small layers of waxy, hairy, and leathery flowers; the days are hotter than the days are colder, the sunny days are more watery than the cloudy days, and the sandy soil is more water than the clay; Period more watering than dormancy. There is a close relationship between the absorptive capacity of the water-bearing root system and the temperature. The decrease of the soil temperature will increase the viscosity of the water and slow the rate of water entering the root system. If the temperature is suddenly lowered, the effect will be even greater. Watering at noon in the summer will cool down the basin soil, causing the water absorption ability of the root system to suddenly drop. At this time, the temperature is high, and the evapotranspiration of the plant is large, causing the body's water to make ends meet. This will cause wilting or dead. Therefore, when watering plants, we must pay attention to the time and the temperature of the water, so that water can be grown at a proper temperature. Practice shows that water should be watered in the morning or evening in the summer, water should be poured in the afternoon in the winter, water should be poured in the spring before noon; the water used for pouring should not be lower than the temperature by 5°C, otherwise the water should be warmed up under sunlight and then warmed Pouring. Water that is poured into soft water to dissolve more calcium ions and magnesium ions is called hard water, and water that does not contain or contains a small amount of calcium ions and magnesium ions is called soft water. Hard water contains more salt, and it is often used for watering flowers to cause brown spots on the leaves and affect the ornamental effect. At the same time, salt accumulation in pots and soils will also affect flower growth. Soft water has a strong activity, and it is easy to break the absorption and utilization of plant roots. General rainwater, river water and pond water are soft water, which can be used for watering; springs and well water are hard water, and should not be watered. In the absence of soft water, tap water can be placed in a pot for several days before being used for watering. In addition, cold water, magnetized water has a strong activity, is a good material for watering flowers. Some people who want to drench water are afraid of over-watering. When they are watering, they will live and pour “half-waisted waterâ€. That is, the amount of water poured will only wet the topsoil, and the middle and lower layers of soil will still be dry. The roots of this flower can not be deeply tied and float in the upper layer of the soil, causing the flower strains to be intolerant to drought, and to form top-heavy, short plants, petiole sagging, leaves chlorosis, and even dead. Therefore, when potted flowers are watered, they must be poured to the bottom of the pot to benefit the growth of the flowers.
