Most of the problems for amateur flower growers are created by representatives of the flora planted in large, voluminous pots or barrels, the height of which exceeds 30 cm. As practice shows, they most often suffer from waterlogging. To protect such plants, you can purchase one of the fairly simple devices that allow you to determine the level of soil moisture.
Before watering the specimens in tubs, following the instructions, you will use the indicator, the arrow on the scale of which will show if the soil is dry or still wet. Cheap devices wear out quickly enough, at some stage they begin to show very dubious readings. Based on this, ideally, it is worth changing the measuring device annually.
If mineral salts have accumulated in excess in the soil, even a new apparatus will be wrong. This happens if plants are watered with too hard water for years. This is the case when incorrect indicator data is a signal that the flower's land needs to be urgently changed.
Modern sound moisture meters are convenient. As soon as the plant begins to feel thirst, the device informs about it with a ringing or, for example, a lingering whistle. It is advisable to install such a device in a flower pot that requires moisture earlier than others. Before watering the plants, it is worth checking them with any of the above methods.
