Excess water is harmful to plants

Too much water is not good for houseplants

When plants wither or turn yellow leaves, this is a signal for many flower lovers to water. The plants are then watered intensively; the actual causes of the symptoms of damage are not investigated. If waterlogging in the root area is the cause of the wilting, yellowing or shedding of the leaves, adding water is the wrong measure. It is advisable to check the soil moisture in the flower pot before watering.

When plants get too much water,

this is often more harmful for them than a temporarily reduced water supply. Too much water in the soil displaces the soil air, depriving the roots of the vital oxygen and, in the worst case, suffocating the roots. The above-ground parts of the plant then receive neither water nor dissolved nutrients - they wither. The plants are "dead-poured".

Too much water damages the roots

If water remains in the planter or saucer for a long time, the roots cannot absorb water, although there is enough moisture. Plants usually do not recover because some of the roots are already rotten.

Waterlogging is caused by too frequent watering or by a clogged drain hole in the pot. Too tight pots are also dangerous because they are difficult to control. That is why it is better to choose larger planters.

First aid for wet plants

As an immediate aid, pot the plant out, remove the rotten roots and the wet, mostly structurally deteriorated soil, and pot the "patient" with new soil in the same or, if the root ball has been greatly reduced, in a smaller pot again . As with cuttings, a plastic bag is pulled over the plant and pot as protection against evaporation so that the plant quickly forms new roots and recovers. This emergency aid is only really effective in the vegetation period from February / March to around September / October. There is no repotting time in the cloudy winter months.

Soil moisture and temperature are related

The lower the temperatures, the less often the plants need water. If the soil temperature is too low, the plant cannot absorb any nutrients. This does not only play a role in earth culture. Even in hydroponics, the nutrient solution level must never be too high or the temperature of the solution too low. Otherwise there is a risk of dying off plant parts or cork growths on leaves and stems. Eventually, the roots can rot completely.

A wet floor is always a cold floor. - The cooler the plants are, the drier it has to be in the planter.
