Soilless cultivation of flowers and notes on water and fertilizer care for premium indoor flowers
As people's living standards improve, personal cultivation and hobbies are also constantly changing. Many people like growing flowers, and some rare and precious flowers, as the outstanding ones among indoor flowers, are more likely to die if not cared for properly. This article gives a brief introduction to the care of premium indoor flowers.
1. Pay attention to the placement position and the light provided
For rare and premium flowers, such as Phalaenopsis (moth orchid) and Cymbidium (large-flowered cymbidium), they generally cannot be placed in direct sunlight, but at the same time the light must not be too weak. Some families, in order to beautify the indoor environment, place flowers in a living room with weak light, or even next to a TV or air conditioner. This not only easily causes the appliances to absorb moisture and thus affects their service life, but is also a kind of torture for the flowers, which absorb a certain amount of radiation, directly affecting the flowers' appearance and life. So it is best not to leave flowers in these places for a long time. Many rare and precious flowers have very high light requirements. In summer especially, shading measures should be taken (a 50% shade net can be used) to avoid direct sunlight; in winter, since the light is weaker, the flowers should be placed where sunlight can reach them.
2. Strictly control indoor temperature and humidity
Different flowers have different requirements for temperature and humidity, and the control of temperature and humidity directly affects whether the plant blooms or not. For example, Anthurium has relatively high requirements for temperature and humidity, requiring the temperature to be controlled between 15~30°C and the humidity to be controlled at 65%~85%. Of course, flowers in different regions also have different requirements for temperature and humidity. For example, buildings in the north are relatively dry, so clean water that has been left standing for more than 24 hours should often be sprayed on the leaves. Some flowers, such as Phalaenopsis and Cymbidium, cannot have water sprayed directly on the flowers.
3. Water and fertilizer management
The water quality in the north is generally alkaline. The pH is around 7.2~8.0, while most rare and precious flowers prefer acidity. They require a pH value between 5.5~6.5. Therefore, the water used for watering flowers must be treated. 1% edible white vinegar or 1% ferrous sulfate can be added to adjust the water quality, and water thoroughly once a week. For fertilizing, homemade fertilizer water can be used. There are generally three methods: first, put soybeans in a container, ferment them, and then dilute before use; second, soak sesame paste residue for 2~3 days and then dilute it, but this method will have an odor, so a few pieces of orange peel can be buried in the flower pot to remove the odor; third, buy special flower fertilizer from the flower market.
4. Keep the flowers clean and tidy to prevent the occurrence of pests and diseases
Under normal circumstances, chemical methods are not used to prevent insects and diseases, because chemical reagents are harmful to people and the environment. A small piece of cotton cloth can be used to gently wipe the leaves, especially the undersides of the leaves. This can achieve the effect of improving ventilation and preventing insects.
