Ideal water quality
For watering, use lukewarm water, because especially those that need heat are reacting sensitive to cold. Keep the water out of the tap for at least 24 hours at the watering so that it will become lukewarm. Since tap water usually contains an excessive amount of limestone that damages plants in the very long run, be cautious to not warm water with excessive water. The limestone water can be mostly quickly characterized with white (mineral) sediments on sheets or substrates. Azaleas, hortenzens, bromeliads, orchids and ferns are allergic to contaminated water. Also, Christmas stars and African violets do not tolerate limestone. It is best to water the area plants and flower with a softwater. Start collecting it if it’s raining for a while. This lessens the degree of pollution caused by the environmental effects.
It’s critical to have an instinct for when the timing is right for watering flower. Most of them should be watered precisely when the upper layer of the ground is dried. Experts test soil moisture with soil. Press the floor with your thumb or cursor to a centimeter deep. If you feel the earth is still wet under the maximum layer, don’t water yet. The clay jar with white spots on the outside wall typically warn about the dearth of water. You could also assist by tapping on your fingers above a clay wall. If the ground remains moist enough, listen to a rather top sound. The noise of the dried earth is apparent.
