The plant prefers a slightly acidic soil pH of around 6.0-6.5 and is considered toxic to pets and humans if ingested.
Pests that may infest Hawaiian Pothos include spider mites, mealybugs, and scale insects. The plant is also susceptible to root rot if overwatered.
How Do You Identify a Hawaiian Pothos?
To properly identify a Hawaiian Pothos, the first step is to be able to distinguish it from other Pothos plants. Here’s a guide on how you can accurately identify one.
How to identify young Hawaiian pothos:
- Leaf Shape: The leaves of young Hawaiian Pothos are heart-shaped, with a pointed tip.
- Color of Leaves: The leaves are a beautiful shade of blue-green, which sets them apart from other pothos plants.
- Size and Pattern of Veins: The veins on the leaves are pale green and run parallel to the leaf edges.
- Stem Structure: The stems are thin and twine around any support they can find.
- Root System: Young Hawaiian Pothos has a weak and delicate root system, so it is best not to repot them too soon.
- Fruits: Young plants do not produce fruits.
- Location and Environment: Hawaiian Pothos grows well in bright, indirect light but can tolerate low-light conditions.
How to identify mature or giant hawaiian Pothos:
- Leaf Shape: The leaves of mature Hawaiian Pothos become more elongated and take on a lanceolate shape.
- Color of Leaves: The leaves remain a blue-green color but may darken slightly.
- Size and Pattern of Veins: The veins become more pronounced and white in color.
- Stem Structure: As the plant matures, the stems thicken and become more woody.
- Root System: The root system becomes stronger and more developed with age.
- Fruits: Mature plants can produce small white flowers and develop green berries that eventually turn black.
- Location and Environment: Mature Hawaiian Pothos can tolerate low light conditions and prefer bright, indirect light. They prefer a humid environment and can benefit from occasional misting.
Hawaiian Pothos Care Needs
Hawaiian Pothos are relatively easy to care for since they don’t require a lot of fuss. Here’s a quick overview of the basics:
Hawaiian Pothos requires bright but indirect light when grown indoors. Direct sunlight can burn the leaves and cause unsightly spots that won’t recover.
Therefore, avoiding direct sunlight and placing the plant in a warm spot exposed to indirect or bright light is essential.
The ideal lighting environment for Hawaiian Pothos is an area that receives eight to ten hours of optimal lighting daily.
If you cannot provide this, you can purchase LED grow lights and use them for 10-12 hours daily.
Note that Hawaiian Pothos will show signs that it needs more light. The leaves may develop dark brown spots or start to yellow, and the soil may take too long to dry.
The growth rate may also slow, and the plant may become leggy, lose variegation, or contrast in leaf colors.
To maximize light exposure for your Hawaiian Pothos, follow these tips:
- Find a well-lit spot like a patio, doorway, or window.
- Position the plant 4-5 feet from south-facing or east/westward-facing windows for morning/afternoon sun.
- Rotate the plant every few weeks to ensure all parts receive equal light exposure.
- Consider using artificial lighting if you’re unable to provide enough natural light.
Soil Requirements for Hawaiian Pothos
Soil plays a major role in the growth and health of your Hawaiian Pothos. The type of soil used and its drainage and aeration capabilities can greatly impact the plant’s well-being.
The ideal soil mixture for a Hawaiian Pothos should be well-draining, light, and not densely packed.
A mixture with organic matter formulated specifically for pothos is recommended. Soil that is too dense or does not have adequate drainage can lead to root rot, which can kill the plant.
The soil pH should also be considered when planting Hawaiian Pothos. A pH range of neutral to slightly acidic (7 to 5.5pH) is ideal for pothos.
If the pH level is too high, lime can be added to raise it, and sulfur can be added to lower it if it is too low.
Maintaining the correct soil moisture is crucial for the health of your Hawaiian Pothos. The soil should be slightly damp but not waterlogged or bone dry.
Pothos-specific soil will retain the correct moisture, preventing overwatering or underwatering.
Proper soil aeration is also essential for your Hawaiian Pothos. Soil that is too compact can hinder root growth and lead to suffocation of the roots.
Adequate soil aeration supplies the roots with the necessary oxygen for healthy growth and reduces compaction.
Several commercially available potting mixes are suitable for Hawaiian Pothos. Some recommended ones include Perfect Plants Organic Pothos Soil.
Alternatively, you can mix your soil with materials like Coco Coir, Perlite, Vermiculite, and Compost.
Signs that the soil is unsuitable for your Hawaiian Pothos include stunted and fungus growth.
If you notice any of these signs, it may be time to repot your plant in fresh, suitable soil.
Pothos Watering Requirements
Pothos prefers moderate watering. When the top 2 inches of soil is dry, it’s time to water the plant.
The best way to test soil dryness is by using a moisture meter, which accurately records the soil’s moisture content.
A reading of 3 on the moisture meter indicates that the soil is dry. Alternatively, you can check the moisture level using a finger test or poke-a-stick method.
Water pothos once a week during the active growing seasons of summer and spring. As growth slows down or becomes dormant in winter, water the plant less frequently, typically once every two weeks.
How to water pothos
- Water pothos until the soil is completely saturated. Use rainwater or distilled water at room temperature.
- Avoid using mineralized or chloramine water, as they can harm the plant.
- When watering, add water slowly and let each pour soak in.
- Ensure that water runs out of the drainage holes, and empty the drain tray to prevent standing water.
- Avoid getting the leaves wet, as it can cause damage.
Pothos watering tips
It’s better to slightly under-water than over-water pothos. Adding water is far easier than removing it. Here are some signs to look for to know if your pothos needs more or less water:
Signs of underwatering
- Drooping leaves
- Dry, brittle leaves
- Slow growth
Signs of overwatering
- Yellowing leaves
- Soft, mushy stems
- Root rot
- Fungus growth
Temperature Requirements for Pothos Plants
Pothos plants are native to tropical climates, which means they thrive in moderate to high humidity and minimum temperatures of 64.4°F (18°C).
While it’s unnecessary to replicate the exact climate found in their natural habitat, you must provide the right temperature range to keep your Pothos plant healthy and happy.
Ideal Temperature Range for Pothos Plants
