Can Phalaenopsis orchids be grown with rainwater, and can they be placed outdoors on rainy days?
Surely every friend who grows flowers and plants hopes their flowers will thrive, and among these tasks, watering is the most common part of maintenance. If you are always lazy in the process, or tend to forget things, and cannot remember to water the flowers for several days, the flowers at home may begin to wilt, the leaves turn yellow, and in serious cases they may die outright. To solve the watering problem, some people come up with setting a timed alarm as a reminder. Does this count as scientific flower growing? Is it actually good for Phalaenopsis orchids?
When caring for Phalaenopsis orchids, watering is usually different in the four seasons, and the watering frequency is also different. For example, in spring and autumn, the temperature is relatively more suitable than in summer and winter, and it is also a vigorous growth period for Phalaenopsis orchids, so at this time the number of waterings should be increased, with 2 times a week recommended. In summer, there are generally many high-temperature days, so besides increasing the watering frequency, you should also spray water around the plant at the right time to raise the air humidity. In the cold winter, the plant should be moved indoors, the number of waterings reduced, and the potting soil kept slightly moist.
At the same time, regarding watering, many flower growers wonder whether rainwater can be used to water flowers. The editor thinks this method is good, but in the north, rainwater cannot be used in all four seasons. Especially in spring and winter when smog is heavy, there are relatively more bacteria and dust in the air, so this kind of rain is not recommended to collect for watering flowers because it is not clean. In the north, only when the rainy season arrives, with frequent rain and clean air, can the rainwater at this time be used with confidence, while the south has frequent rain in all four seasons, so rainwater can be used to water flowers all year round.
What are the benefits of rainwater? It can provide oxygen and trace elements, promote the growth of flowers and plants, and also improve soil pH. So how should rainwater be collected?
It is generally recommended to collect it in a bucket, or simply move the flowers outside before it rains. Especially when the raindrops are small, countless raindrops fall and quietly wash the leaves clean, with no need to manually wipe off the dust. If there is thunder during rain, the rainwater may contain nitric acid, and nitrates can become the nitrogen fertilizer plants need once they reach the soil. In addition, collected rainwater is best used up the same day, because if left for a long time it easily breeds bacteria and insects.
