good nutrient supply supports vibrant leaf coloration.
🌱 Substrate
A loose, airy soil environment is important:
-
well-draining
-
nutrient-rich
-
a mixture of high-quality houseplant soil, perlite, and possibly some pine bark works well.
🪴 Repotting
-
every year or every 2 years in spring
-
when roots grow out of the bottom of the pot, it's time for a larger container
-
choose a pot that is only slightly larger than the old one.
✂️ Pruning
The Syngonium Red Heart tolerates pruning very well.
-
simply remove dried or unsightly leaves at the base
-
overly long vines can be trimmed to make the growth bushier and more compact again
-
use clean tools.
🌱 Propagating Syngonium Red Heart
Propagation is very easy with cuttings:
-
cut stem cuttings with at least one leaf node and possibly aerial roots
-
simply root them in a glass of water or place them directly in moist propagation substrate.
☠️ Is Syngonium poisonous?
Yes – unlike the Maranta, the Syngonium Red Heart is slightly poisonous.
-
contains calcium oxalate crystals
-
not safe for cats and dogs
-
if ingested, it can cause irritation of the mucous membranes in humans and animals.
👉 It's best to place it out of reach of pets and small children, ideally hanging in a plant hanger or on a high shelf.
🧠 Other Care Tips
The Arrowhead plant benefits from having its leaves occasionally wiped with a soft, damp cloth to remove dust. This allows it to breathe better and absorb light optimally.
If the plant loses its beautiful pink color and becomes increasingly green, it is likely in too dark a spot. Moving it to a brighter location (without direct midday sun) usually quickly brings back the pink tones in the new leaves.
✅ Conclusion
With its enchanting pink coloration and uncomplicated care, the Syngonium Red Heart is an excellent choice. It is easy to care for, adaptable, and creates a cheerful, warm atmosphere as a bushy tabletop plant or an elegant hanging plant. Let this beautiful plant enhance your interior.
