Goldfish Plant Care And Growing Guide 101

Goldfish Plant Care And Growing Guide 101

Sharing is caring!

The Goldfish Plant (botanical name Columnea gloriosa) is one of the less known but all, the more beautiful houseplants that are easy to care for. The fish-shaped flowers and their color have earned the nickname ‘goldfish plant’ in the English-speaking world. 

Botanically, the genus Columnea belongs to the family of Gesneriaceae. Typical for all columneas are the long, hanging shoots (up to 95 cm). For exactly this reason, Columnea gloriosa is best suited as a hanging baskets plant.

Goldfish Plant Care

To best care for a Goldfish plant, use a regular potting soil mix. Provide bright indirect light. Water once a week. The ideal temperature is 64-75 degrees Fahrenheit. Water once a week once the soil is almost dry. Fertilize every two weeks in spring and summer.

Goldfish Plant Plant Care

Soil

The Goldfish Plant is anything but delicate when it comes to soil. Choosing the right soil should be relatively easy even if you don’t have a green thumb.

A regular potting soil mix is sufficient for the goldfish plant, but it can also be kept in hydroponics (a method of growing plants without soil). Another good choice is African violet potting soil (containing peat moss & perlite). 

Light

Columneas thrive best in light to semi-shady locations. The plant cannot tolerate direct sunlight, as this will cause its leaves to burn. If you want to use artificial lights, that also works well with Goldfish plants.

Placing your plant around 1 meter from an east-facing window generally produces great results. Keep in mind that light conditions change throughout the day and the season. Therefore, it might take you some time to find the perfect spot for your Goldfish plant. 

Watering

Water once a week.

Spring to summer: Water your Goldfish plant with lukewarm water (tepid water). Watering your plant with cold water could result in leaves with unsightly brown spots. The soil should be kept slightly moist at all times.

In winter, however, you need to decrease watering. Make sure that the soil almost becomes dry before “rewatering.”

Temperature

Provide average room temperatures between 64-75 degrees Fahrenheit (18 to 24 degrees Celsius) all year round.

Humidity

The ideal humidity is 40-50%. Moderate humidity is best for this plant.

Fertilizer

Feeding your Goldfish plant with a high-phosphorous fertilizer is a good idea.

The dosage of fertilizer should always be slightly below the dosage recommended by the manufacturer, as this avoids overfertilization, which is also unfavorable to Columnea gloriosa.

Beginning in spring and up to summer, feed your plant every two weeks. In colder months (winter), feeding your Goldfish plant once a month will be sufficient.

Propagation

Goldfish plants can be propagated by rooting stem tip cuttings. The best time for propagation is spring or summer. It is always a good idea to stick more cuttings than you need because there is always a risk that some of them fail.

You might also want to use a rooting hormone (rooting) powder when propagating your leafy friend, as this will drastically improve your odds of success.  

Growth

Columnea Gloriosa is a very slow grower. However, its stems can grow up to 95 cm. Nevertheless, you will want to prune your Goldfish plant regularly for a bushy look. 

Potting

Repot once every two years. As for the choice of container, aim for a medium-sized container. 

How to Propagate a Goldfish plant

To ensure that your Goldfish plant becomes your lifelong friend, let’s look at the best methods to propagate this gorgeous houseplant.

As far as propagating houseplants go, six different techniques are commonly used:

  • air layering
  • division
  • rooting stem cuttings
  • rooting leaf cuttings
  • simple layering
  • growing new plants from seeds

However, it needs to be mentioned that not every method applies to every houseplant. While some methods may work great with your houseplant, others might not. 

So what is the best method to propagate your Columnea Gloriosa?

The best method to propagate your goldfish plant is by rooting stem cuttings or, more precisely, rooting stem tip cuttings

To propagate a Goldfish plant, follow these steps:

  1. Search your plant for healthy, non-flowering stems.
  2. Use a sharp, sterile knife to proceed with the cuttings.
  3. Cleanly cut the stems that you would like to propagate. Leave some of the stems (about 5 to 7.5 cm) while doing so; we only need the stem tip! (about 7,5 cm long) to propagate
  4. Pull off the bottom leaves of the stem cuttings.
  5. Dip the stem cuttings in rooting powder (rooting hormone). If you don’t have that, you can easily find it in garden centers or on the internet
  6. Root the stem tip cuttings (remember: should be about 7.5 cm long) in a container of your choice. As for the soil, we recommend a light mix of peat & perlite. 
  7. Lightly water your newly propagated plants.

Note: Newly rooted cuttings will take at least a year to bloom. The best time for propagating your Goldfish plant is in spring/summer

Watering your Goldfish plant

Water about once every 7 days as a general rule of thumb.

As with any other houseplant, it doesn’t make sense to water your Goldfish plant according to a fixed timetable. The important thing to remember here is that your Goldfish plant likes it pretty moist.

So, what you should do is you should check if the top layers 1-2 inches (meaning the top 2.5-5 cm) of the soil are dry or not.

You can put your finger inside the compost to verify. 

If you conclude that the compost’s top is dry, you should give your leafy friend some water.

Make sure to use either distilled water or rainwater

Note: Your goal should always be to make (and then keep) the compost of your Goldfish plant (slightly) moist but not wet.

Both underwatering and overwatering your Goldfish plant can result in serious damage to your plant.

A lack of water and an excess of water can lead to wilting. Proper watering of your Goldfish plant (basically any houseplant) is essential, and incorrect watering might be the number 1 reason why houseplants die.

Goldfish Plant Pest and Diseases

Problem: Brown leaf tips

Cause: If your Goldfish plant features brown leaf tips, chances are that you have an excess of calcium in the soil. 

Remedy: Make sure to use a fertilizer that is low in calcium. When watering, rainwater or distilled water should be your weapon of choice. Tap water is not recommended. If you do use tap water, make sure that it is lukewarm. 

Problem: Faint webbing on leaves

Cause: Most likely, you are dealing with Spider mites. An infestation with spider mites will likely occur in late fall/winter. Spider mites are super tiny. They are tough to spot. You need a magnifying glass actually to see them. 

Remedy: One way to go about this is to use a water spray to blast off the pests gently. Spider mites generally hang on the undersides of the leaves, so you need to spray that part of the leaf specifically!

If the infestation has already got bad, you might need to prune off badly infested branches.

And if all of that is not helping, you might even need to discard your Goldfish plant. Spider mites are tiny little devils 🙁

Problem: White fuzzy stuff on leaves and stems

Cause: If you discover white cottony deposits on your plant, you are likely dealing with mealybugs

Solution: The first thing you should do when discovering that mealybugs infest your houseplant is always to isolate your plant. After that, you should try to wipe off the mealybugs with the help of a cotton bud soaked in insecticide. However, it is not easy to get rid of mealybugs. And in some cases, you might need to discard heavily-infested plants.

Side note: Please remember that the best way to avoid pests on your houseplants is to ensure your plant stays healthy. Pests are far more likely to attack plants in unhealthy conditions.
