Ideal water quality
For watering, use lukewarm water, because notably those that want heat are reacting sensitive to cold. Keep the water from the tap for at least 24 hours at the watering so it becomes lukewarm. Since tap water generally contains an excessive amount of limestone that hurts plants in the long term, be careful not to water with excess water. The limestone water can be largely quickly identified by snowy (mineral) sediments on sheets or substrates. Azaleas, hortenzens, bromeliads, orchids and ferns are sensitive to polluted water. Also, Christmas celebrities and African violets do not tolerate limestone. It is best to water the area plants and flower with a soft, rain water. Start collecting it if it’s raining for a while. This lessens the level of contamination caused by the environmental effects.
It is essential to have an instinct for when the timing is suitable for watering flower. Most of them should be watered exactly when the upper layer of the ground is dried. Experts test soil moisture with dirt. Press the ground with your thumb or cursor to a centimeter deep. If you believe the earth is still moist under the highest layer, do not water yet. The clay jar with white spots on the outside wall generally warn about the lack of water. You can also help by tapping on your fingers above a clay wall. In case the earth is still moist enough, then hear a rather top sound. The sound of this dried earth is clear.
