Mold on Seramis Tongranulat - what to do?: granules

When mold grows on the Seramis clay granules, good advice seems expensive. The removal alone helps little and even after a change, the unsightly surface can quickly reappear. With the right knowledge, however, it is very easy and fast to prevent stains on the granulate from even forming and to remove them if necessary. How to proceed for this purpose, interested in the following instructions. Even if it is not mold.

Dry surface

If there is an apparent mold on the Seramis clay granulate, you should first look closely. A hard, dry, white or gray surface is very common - but has nothing to do with mold. Instead, it is deposited lime, which seems to grow on the granules but formally. Responsible for this is hard, so lime-rich, irrigation water.
If the water evaporates or is taken up by the roots of the plant, the lime deposits on the surface of the clay. The more water and the faster the evaporation, the faster the apparent growth of the pavement. In addition to water as a cause, unfavorable fertilization can also be responsible. In this case, color-differentiating and even optically 'furry' coating on the stones is possible.


To prevent the unsightly coating from forming on the Seramis clay granules, use only low-calcium, soft water to water the plant. For this purpose it can stand or be filtered. Alternatively, collected rainwater offers. If the apparent mold occurs directly after a fertilizer application, the inorganic agent is the cause. Preventively, such things can only be avoided.

Various methods are available for the removal. First, the removal and replacement of the upper layer. This variant is quick and easy but not very cost effective with many affected pots. Alternatively, the surface can be covered with gravel or decorative stones to improve the look. With a little more effort, the rolling of the affected layers is connected.
Lime is usually first on the surface due to evaporation. If the complete granules are not yet occupied by the deposit, the uppermost layer can simply move downwards. If you still want to save the Seramis, you can try the following tips.
  • Put the baking powder on the moistened granules
  • Soak the seramis in vinegar essence
  • Add citric acid to the stones
Before these measures, the Seramis course, from the pot to take. It should then soak for about an hour in one of these remedies, which will dissolve the limescale deposits. Then it can be brushed off or placed in a closable container with rice grains and some water and shaken vigorously. Afterwards, rinse thoroughly. Due to the rough surface, it may occur despite the solvent and the manual cleaning that the deposits can no longer be solved.


True mold occurs relatively rarely on the Seramis clay granules. The root of the problem is then usually the root - or rather root rot, which works in the substrate from bottom to top. Likewise, organic residues, such as plant parts, insects or soil residues between the granules, the molds may be. The following factors are also possible:
  • Too cold, darker location
  • Excessive pouring
  • Constantly high humidity
  • Lack of drying between waterings


The prevention of mold on Seramis clay granules begins at the onset of the plant. The roots must be completely free of the previous substrate. The same applies to dead root parts. Even small Erdkr├╝mmel or rotten pieces can become rotten spots. Also in the ongoing care incidental leaves, insects and other as quickly as possible from the granules read.
Furthermore, the right location and the coordinated casting help. If seramis can dry properly, at least in the upper layers between the waterings, the danger of mold is considerably reduced.


If mold is found on a foreign body, such as a leaf, on the clay granules, the removal of this piece may already help. For safety, the granules around the stove should also be removed. Different with area covering. Here it is necessary to remove the entire substrate. The spores may only 'bloom' on the surface but have spread throughout the pot at such an extent. The removal of the topmost layer would only ensure short mold freedom.

The plant root should be examined for affected sections and, if necessary, treated with a fungicide. The pot is to be thoroughly cleaned. The Seramis can now be disposed of or released from the mold.For this purpose, in turn, offer various measures.
Possible are:
  • Soaking in diluted vinegar essence
  • Soaking with citric acid
  • Insert into a suitable fungicide for plants
  • Heat in the oven to 150┬░ C for about one hour
Acid, fungicide and heat are used to kill the spores sustainably. Of course, the granules should then be rinsed thoroughly to eliminate any residue. Before a plant is stopped again, it can be stored for a few days and checked for any re-mold.
