Rate this post

Philodendrons are a beloved staple in the houseplant community, cherished for their lush, verdant leaves and easy-going nature. They’re the friends you wish you had—undemanding, adaptable, and always ready to thrive in varying indoor conditions.

A common question among plant enthusiasts is whether these hardy plants can ditch the dirt and go for a swim. Can these green beauties really grow in water only?

💥 Quick Answer

Absolutely, philodendrons can be propagated and grown in water as a long-term growing medium.

We’re not spinning yarns here—transitioning your philodendron to an aquatic life is doable and, surprisingly, might even add a sleek, modern twist to your décor.

It’s about getting the basics right: a bright spot without direct sunlight, a container that’s chic and functional, and the patience to let your green buddy adapt to its new aquatic environment.

Remember, though, while philodendrons are versatile, they do have a change of heart when growing in water versus soil, especially when it comes to size and growth rate.

So, if you fancy a bit of green experimentation, let’s dive in and explore the water world of philodendrons.

Optimal Conditions for Water Growth

When growing philodendrons in water, achieving the right conditions is crucial for their health and vitality. We’ll discuss the importance of light, water quality, and the temperature and humidity to provide your water-grown philodendrons with the best environment to thrive.

Light Requirements

🔆 Light Requirements

Philodendrons prefer bright, indirect sunlight. Too much direct sunlight can burn the leaves, while too little can cause leggy growth.

We should aim to place them in a spot where they receive dappled sunlight or a soft filtered light similar to their natural rainforest habitats.

Water Quality

The quality of water plays a pivotal role in the health of philodendrons grown in water.

We must use chlorine-free water, which means letting tap water sit for 24 hours before use. This allows chlorine to evaporate, giving the roots a more hospitable environment.

We may use distilled water as another safe option.

Temperature and Humidity

🌡️ Temperature Requirements ☔️ Humidity Requirements

Philodendrons prefer a warm environment with temperatures ranging between 65-78°F (18-25°C) and enjoy high humidity levels.

Our home’s natural humidity will often suffice, but it’s beneficial to aim for around 60% humidity, which we can achieve using a humidifier or pebble tray if needed.

Propagation and Rooting Process

In propagating philodendrons, we prioritize the health of our cuttings and the environment we provide for root development. Let’s dive into the specifics.

Preparing the Cutting

When propagating, we need a healthy philodendron stem cutting. With clean and sharp pruning shears, we snip a 3 to 6-inch portion of the stem.

It is essential to leave at least one node on the cutting, as this is where root growth will commence. Ideally, we make our cut just above a leaf node to encourage the parent plant to continue growing.

The Role of Nodes and Aerial Roots

The node is where the magic happens. It’s the knobby section along a stem where leaves and roots originate.

In our experience, aerial roots, which sometimes form when the plant is still in the soil, can give our cuttings a head start in water as they adapt to their new environment more swiftly.

We always look for these when selecting a section to cut because they can significantly speed up the rooting process.

Root Development in Water

For rooting, we partially submerge the node in water, being careful to keep leaves out of the liquid to prevent rot.

The transparency of glass vases allows us to watch the roots develop, which is both thrilling and practical for monitoring progress.

We’ve found that changing the water regularly keeps it clear of bacteria, which could hamper root growth.

Adding a drop or two of liquid fertilizer can provide nutrients, but it’s a delicate balance as too much can cause harm.

Patience is key because roots can take from one to several weeks to appear, but once they’re a few inches long, it may be time to transplant.

Long-Term Care of Philodendrons in Water

Growing philodendrons in water is not just a novelty; it’s a practical approach to indoor gardening. Our focus here is to maintain a water-grown philodendron over the long term, ensuring it thrives and graces our space with its luscious green.

Fertilizing Water-Grown Philodendrons

💥 Balanced Liquid Fertilizer

When it comes to nourishment, a balanced liquid fertilizer is paramount.

We mix 1/2 or 1 teaspoon of it with two gallons of water and treat our green friends once a month.

Remember, over-fertilizing can lead to more harm than good, causing stunted growth or worse.

Pruning and Maintenance

✂️ Regular Pruning

Pruning isn’t just about aesthetics; it’s vital for health.

We snip off yellowing leaves or overgrown vines to encourage fuller growth and prevent legginess.

Think of it as giving your plants a refreshing haircut — it’s necessary, and they’ll love you for it.

Preventing Common Problems

⚠️ Watch Out for Algae

Algae growth can be an issue in water-grown setups.

It’s crucial to keep the jar clean and change the water regularly — typically every week or so.

To prevent algae, avoid direct sunlight on the water and consider using opaque containers.

Vigilance is key, both for clean water and happy plants.

Philodendron Varieties Suitable for Hydroculture

💥 Quick Answer

We find that not all Philodendron varieties are equally suited for hydroponic growth, but some adapt splendidly to life aquatic.

Philodendrons have a diverse array of growth habits suitable for hydroculture. Let’s discuss a few that make a splash in a water-based setup:

The Heart Leaf Philodendron (Philodendron hederaceum), with its amiable heart-shaped leaves, consistently proves that it doesn’t mind getting its roots wet.

It’s an excellent choice for beginners dipping their toes into hydroculture. In our experience, it maintains a more compact size in water but doesn’t skimp on charm.

The Velvet Leaf Vine or Philodendron micans brings a touch of sophistication with its suede-like foliage. When in water, they display that same soft heart-shaped leaf, albeit on a smaller scale.

Despite its luxurious look, it’s unpretentious and thrives in a jar of water:

💥 Philodendron Brasil

The Philodendron Brasil, a variation of hederaceum, carries variegation that can be quite striking within the hydroponic setup. With green and golden yellow leaves, it’s like carrying a piece of the Brazilian sun in your living room.

Split Leaf Philodendron, though not usually grown hydroponically due to its larger size, small specimens can start their journey in water. Their iconic “split” leaves bring drama even to a simple vase.

Philodendron ‘Burle Marx’ adapts readily to water, thanks to its love for humidity in its native tropical jungles. The elongated, heart-shaped leaves give this water-grown philodendron an air of elegance.
