Waterstick is suitable for all soil types and fine granulates.
Whether it is a strong plastic sheet for fresh potted plants or
a hard plastic part to be sticked in an already densely rooted substrate,
Waterstick accurately shows whether there is moisture in the soil.
This is extremely helpful, as most of the plants are watered too much.
You must, however, follow the care instructions for the plants,
as their needs are very different.
The most important rule is:
"Water plants only when required,
not on a regular basis."
And there you go with beautiful plants.
