How do I encourage my goldfish plant to bloom? This plant will need a few different care points in place in order to bloom. Keep fertilizing regularly, a fish based fertilizer with lots of nitrates and high in phosphorus will be great for this plant.

Instructions

Soil Preference:

  1. This epiphyte requires a light soil.
  2. A mix of potting soil, orchid bark and perlite will keep the roots happiest.
  3. Our mix for this plant is 60% potting mix to 20% perlite and 20% orchid bark.
  4. Mix the ingredients in a large bowl to create your mix. Use a mask when working with dry perlite.
  5. A light and quick draining soil is best for this plant
  6. A heavy soil potting mix is not recommended for goldfish plants.

Pot Size and Type:

  1. Goldfish plants can be grown in pots that fit the root size.
  2. This plant likes to be slightly pot bound.
  3. Any well drained pot can be used. It MUST have drainage.
  4. Repot every 2-3 years This plant can go longer than most plants in a smaller pot due to its shorter root length.
  5. Don't jump to a huge pot from a small one.

Lighting:

  1. Goldfish plants enjoy lots of bright indirect.
  2. The plant will not bloom without optimal amounts of sunlight
  3. For optimal growth and blooming set the plant in bright indirect light.
  4. Shield this plant from strong direct light in summer south and west sunny windows. The leaves will burn.
  5. Tip: Window sheers or blinds can offset some brief periods of high direct light.

Watering:

  1. Water your goldfish plant when it is dry an inch down. This plant enjoys moist soil but will not do well with constantly wet roots. Try a watering schedule of every other week.
  1. Watering is best done on a regular schedule so the plant is not over or under watered. Both can cause stress on the plant.
  2. This tropical plant enjoys humidity. In dry climates these plants will thrive with a humidifier nearby. or set it in your kitchen or bathroom. For a really dry climate frequent misting will help.
  3. Avoid getting leaves wet when watering.
  4. In dormant winter months reduce watering to when the soil is dry down halfway .
  5. Never let this plant get wet feet. If the soil is compacted the bottom of the soil can remain wet which encourages root rot and Fungus Gnats. If you see yellow leaves you are probably overwatering.

How to Fertilize:

  1. Apply a good quality balanced fertilizer (linked in materials) or bloom boosting orchid fertilizer monthly through Spring and summer.
  2. Decrease feedings by late Fall and allow your plant to rest through the winter months.
  3. Look for brown spots on the leaves of your goldfish plant. This may indicate an over concentration of salts in the roots from over feeding. It can burn the leaves.
  4. The remedy is to set the plant under a faucet of water and let the water run through for 10 minutes or so to flush out the extra salts.
  5. Allow the pot to Completely drain. Discontinue fertilizer until the plant recovers.

Temperature:

  1. Keep at a low of 65 Degrees F. to upward of 85 Degrees F. It enjoys warmth and humidity.

Pruning and Training:

  1. Goldfish plants tend to grow leggy. Pruning them back helps maintain a well shaped plant.
  2. Sharp Hand pruners are preferred for pruning. They will give a clean cut that will heal quickly.
  3. Wear gloves to prune this plant.

Pests:

  1. All plants can get attacked by pests.
  2. Stress by longterm poor watering practices, poor light, extreme temperatures and soil conditions are contributors to pests.
  3. Spider mites, mealy bugs, scale, thrips and whitefly are the most common houseplant pests you will see.
