Do You Water Orchids From The Top Or Bottom

You should water orchids from the top, and this is the most reliable method for keeping them healthy.

Watering your orchid from the top mimics the natural rainfall they would experience in their native jungle habitat.

When you water orchids from the top, you can thoroughly saturate the bark or moss mix, which ensures the roots get the hydration they need.

Watering from the top is the method most orchid experts recommend because it allows you to flush out excess mineral salts from fertilizers.

In this post, we’ll break down why watering orchids from the top beats bottom watering, how to do it correctly, and when bottom watering might actually be useful.

Let’s dive right into the best way to keep your orchid thriving.
 

Why Watering Orchids From The Top Is The Best Approach

Watering orchids from the top is the most straightforward and effective way to deliver moisture directly where it’s needed.

This method ensures that every part of the potting medium gets wet, which is crucial because orchid roots don’t grow evenly throughout the pot.

Here are the main reasons why you should water orchids from the top:
 

1. It Flushes Out Harmful Salts

When you water orchids from the top, the water runs through the entire pot and carries away built-up salts from fertilizers.

These salts can accumulate over time and burn the sensitive roots of your orchid.

Watering from the top acts like a gentle rinse, keeping the root system clean and free from toxic residue.

If you only water from the bottom, those salts stay trapped in the potting mix and can cause long-term damage.

So for this reason alone, watering orchids from the top is the safer choice.
 

2. It Hydrates The Entire Root System

Orchid roots are adapted to cling to trees in the wild, and they absorb moisture from rain that runs down the bark.

When you water orchids from the top, you replicate that natural flow of water.

Water travels down through the pot, reaching both the upper and lower roots.

Bottom watering, on the other hand, only wets the lower portion of the pot, leaving the top roots dry and stressed.

That’s why watering orchids from the top is the method that guarantees even hydration.
 

3. It Prevents Stagnant Water And Root Rot

When you water orchids from the top, you can easily see when water starts draining out of the bottom holes.

This visual cue tells you the medium is fully saturated and that excess water is escaping properly.

Watering from the top also allows air to circulate through the bark as the water flows, which is vital for orchid roots that need oxygen.

If you water from the bottom by soaking the pot in a tray, you risk leaving the medium too wet for too long.

And overly wet conditions are the number one cause of root rot in orchids.

So watering orchids from the top gives you better control over moisture levels and drainage.
 

How To Water Orchids From The Top Correctly

Now that you know you should water orchids from the top, let’s talk about the proper technique.

Doing it right is simple, but there are a few key steps to follow for success.
 

1. Use Room Temperature Water

Cold water can shock the roots, so always use lukewarm or room temperature water.

When you water orchids from the top, the temperature of the water matters more than you might think.

Warm water is absorbed more easily and won’t cause any stress to the plant.
 

2. Water Thoroughly Until It Drains

Place your orchid in a sink or a basin, then slowly pour water over the top of the potting medium.

Keep pouring until you see water running freely out of the drainage holes at the bottom.

This ensures the entire medium is soaked and that you’ve flushed out any lingering salts.

Allow the pot to drain completely before returning it to its decorative outer pot or saucer.
 

3. Avoid Getting Water In The Crown

When you water orchids from the top, be careful not to let water pool in the crown, which is the center where the leaves meet.

Water trapped in the crown can lead to crown rot, a fatal condition for orchids.

Tilt the pot slightly as you water, or use a watering can with a narrow spout to direct the water onto the bark.

After watering, you can also dab any excess moisture from the crown with a paper towel.
 

When Bottom Watering Orchids Makes Sense

While you should water orchids from the top in most cases, there are a couple of scenarios where bottom watering is acceptable.

Bottom watering involves placing the pot in a shallow dish of water and letting the medium soak it up.

This method is sometimes used for very dry bark that has become hydrophobic and repels water.
 

1. Rescuing Extremely Dry Potting Mix

If your potting medium has dried out completely, it may resist absorbing water from the top.

In this case, bottom watering can help rehydrate the bark by allowing it to wick moisture from below.

But even then, it’s best to follow up with a top watering session to ensure all roots get wet.

Once the medium is rehydrated, you can return to watering orchids from the top for all future waterings.
 

2. For Certain Mounted Orchids

Some orchids are grown mounted on slabs of wood or bark rather than in pots.

For these, watering from the top is still preferred, but you may occasionally soak the entire mount.

Even so, the general rule remains that you should water orchids from the top for potted plants.

Bottom watering should never be your default routine because it doesn’t provide the flushing benefits of top watering.
 

How Often Should You Water Orchids From The Top?

The frequency of watering orchids from the top depends on several factors like humidity, temperature, and potting medium.

A good rule of thumb is to water when the top inch of the bark feels dry to the touch.

You can also lift the pot to feel its weight; a light pot means the medium is dry and ready for water.

In most homes, watering orchids from the top once a week is sufficient.

But if your home is very warm or dry, you might need to water twice a week.

And during cooler months, you can cut back to every ten days or so.

The key is to check the medium regularly rather than sticking to a strict schedule.
 

So, Do You Water Orchids From The Top Or Bottom?

Yes, you should water orchids from the top, and this is the method I recommend for every orchid owner.

Watering orchids from the top delivers moisture evenly, flushes out salts, prevents rot, and keeps the roots healthy.

Bottom watering has a few rare uses, but it should never replace your primary top watering routine.

So grab your watering can, use room temperature water, and give your orchid a good drink from the top.

Your orchid will thank you with vibrant leaves, strong roots, and beautiful blooms.

Now you know exactly how to water your orchid the right way, so go ahead and give it the care it deserves.
