Falling for Fishbones: A Guide to Propagating the Goldfish Plant (Nematanthus gregarius)
The Goldfish Plant, with its charmingly named “fishbone” foliage and vibrant, fishy-looking blooms, isn’t just a quirky conversation starter. This tropical wonder, scientifically known as Nematanthus gregarius, is a delight for plant parents of all levels, thanks in part to its easy propagation. If you’re looking to multiply your goldfish population (the plant variety, that is!), then grab your gardening gloves and dive into these simple propagation methods.
Stem Cuttings: The Go-To Method
Stem cuttings are the most popular and successful way to propagate your Goldfish Plant. Here’s how:
Timing is Key: For best results, take your cuttings in spring or early summer when the plant is actively growing.
Choose Wisely: Select healthy, non-flowering stems that are about 3-4 inches long. Look for stems with at least two sets of leaves.
Make the Cut: Using clean, sharp scissors or pruning shears, snip the stem just below a leaf node (the slightly swollen area where leaves grow).
Prep the Cutting: Remove the bottom set of leaves. If you’d like, dip the cut end in rooting hormone powder to encourage faster rooting, but it’s not essential.
Choose Your Adventure: Water or Soil?
- Water Propagation: Place the cuttings in a clear glass or jar filled with water, making sure the leaf nodes are submerged. Change the water every 2-3 days to prevent bacterial growth. Once roots are about an inch long, usually within a few weeks, you can pot them up in well-draining soil.
- Soil Propagation: Fill a small pot with a mixture of peat moss and perlite or a seed-starting mix. Make a small hole in the soil and gently insert the cutting, ensuring the bottom leaf node is buried. Water lightly and keep the soil consistently moist. Roots should develop in 4-6 weeks.
Tip: Maintain humidity around your cuttings by placing the pot or glass in a propagator or covering it loosely with a plastic bag.
Alternative Approach: Leaf Cuttings
While stem cuttings are more common, you can also try your hand at propagating Goldfish Plant from leaf cuttings:
Select and Snip: Choose healthy, mature leaves and use a sharp, clean blade to cut them cleanly from the stem.
Let Them Rest: Let the cut end of the leaf dry for a day or two, allowing a callus to form. This helps prevent rot.
Shallow Planting: Fill a tray with a moist seed-starting mix and lay the leaves flat on the surface. Secure them with small pebbles or by gently pressing them into the soil.
Create a Humid Environment: Cover the tray with a humidity dome or plastic wrap. Place it in a warm, bright location, out of direct sunlight.
- Patience is Key: Leaf cuttings take longer to root, sometimes up to 8 weeks. New plantlets will emerge at the base of the leaf. Once they’re large enough, carefully separate them and plant individually.
From One Fish to a School
