Do you notice that there are drops on the edge of the leaves? This could be guttation.
The development of guttation
Guttation occurs when the plant drinks too much water than can evaporate through the leaves during the day.
During the night, the pores of the leaves close, preventing the plant from evaporating water, but the roots can still absorb water. This creates a surplus of moisture within the plant. To regulate this, the excess moisture is squeezed out through the pores. These pores are located at the tip of the leaf, where the water droplets become visible.
Avoid guttation
In general, guttation is a natural process in certain plants and is not harmful. It can mean that the plant has received too much water. Keep a close eye on the water meter for this. If your plant has a lot of drops on the leaves, you can give less water and keep the blue float in the middle between the lines.
As described above, guttation is not harmful, but the drops can cause stains on floors or furniture. If you notice guttation, you can catch the drops with a dry cloth.
Plants where it occurs more often
Guttation can occur faster in one plant than in another. This is more common in Monsteras, Strelitzias, Spathiphyllums and Philodendrons (Green and Red Beauty). Guttation can occur in these plants when they get too much water. You can avoid guttation by watering in the morning and reducing the amount of water.
Unfortunately, this is unavoidable for the Banana plant and Alocasias. These plants naturally drip and prevention is more difficult.
