💧 Watering / Water
Unlike swamp plants, Polyscias 'Roble' absolutely dislikes wet feet. Less is often more here.
-
Allow the soil surface to dry out well between waterings
-
Avoid complete root ball dryness
-
preferably water with room-temperature water
-
Waterlogging inevitably leads to root rot and severe leaf drop. Always drain excess water from the cachepot.
🌼 Fertilizing
-
from spring to autumn: every 2 weeks
-
standard liquid houseplant fertilizer is perfectly sufficient
-
stop fertilizing completely in winter
-
fertilize on moist soil to avoid burning the roots.
🌱 Substrate
A loose soil climate is important so that water can drain well:
-
nutrient-rich, but very well-draining
-
structure-stable
-
A mix of high-quality houseplant soil with a good proportion of perlite, sand, or fine expanded clay works excellently.
🪴 Repotting
-
every 2 to 3 years in spring, as it grows rather slowly
-
only repot when the old pot is well rooted
-
Choose a slightly heavier pot (e.g., ceramic or clay) so that the tree-like plant does not become top-heavy and tip over.
✂️ Pruning
Polyscias 'Roble' Vertakt tolerates pruning very well and can be easily kept in shape.
-
does not require mandatory pruning, but tolerates it very well
-
overly long shoots can be shortened in spring to promote compact, bushy growth
-
simply gently pluck off dried or yellow leaves
-
always use clean and sharp tools.
🌱 Propagating Polyscias 'Roble' Vertakt
Propagation is feasible, but requires some patience and the right conditions:
-
done via stem or tip cuttings in spring
-
cut cuttings below a leaf node
-
place in seedling soil and ensure very high humidity (e.g., by placing a plastic bag over the pot) and warm soil temperatures (25 °C).
☠️ Is Polyscias poisonous?
Yes – unlike the Maranta, Polyscias 'Roble' is unfortunately slightly poisonous.
-
contains saponins in the leaves and stems
-
can cause gastrointestinal upset or mucous membrane irritation if ingested
-
toxic to cats, dogs, small animals, and also small children. 👉 It is best to place it in an elevated position or in a place inaccessible to your furry friends and small children.
🧠 Other Care Tips
Polyscias is a real creature of habit: avoid constant changes of location, as it often reacts to them with leaf drop. It also loves high humidity. Regular misting of the leaves with low-lime water prevents spider mites and keeps the foliage fresh. If it suddenly sheds leaves, first check if it has been exposed to drafts or if there is water in the cachepot.

Although it requires a fixed, draft-free location and some caution when watering, it will reward you with elegant, tree-like growth that exudes tranquility and naturalness.
