Top Myths on Watering Houseplants

People are generally very confused over how to water houseplants properly.  The problem is that it is easy to misinterpret a lot of aspects about houseplant care in general. 

This post focuses on one aspect of houseplant care, and that is to help you understand everything about watering your houseplant properly. 

Here are a few watering myths that I’ve come across that I would like to debunk.

Myth #1:  I shouldn’t soak my succulents.  They only need a little bit of water at a time.

WRONG!  Almost without exception, I recommend thoroughly soaking your houseplant, regardless of whether it is a succulent or not. 

And no I’m not crazy.  It works and I speak from experience, so trust me! 

Keep reading though…because you might be wondering “oh I thought succulents don’t like much water?”  Well that’s only partially true.

If you just add a little bit of water (because succulents don’t need that much water, right?), you are doing a big disservice to your plant. 

If you don’t thoroughly soak your plant and just add a little bit of water, you are encouraging a shallow root system.  And if you have a poor and shallow root system, your whole plant will suffer.  Without a healthy root system, you will not have a healthy plant.

Yes it is true that succulents don’t need as much water as many tropical foliage plants, however, you should still soak your plant. 

The critical part for succulents is that after you water, you should wait long enough for the potting soil to pretty much go completely dry before watering again.  And when you do water again, soak it again!  

Let the water drain through the drainage hole and discard any extra water.  Less frequent, but thorough-watering, is superior to frequent mini-drinks of water.

Myth #2:  Houseplants Need to Be Watered Once a Week

WRONG!  Well, the real answer is that it depends!  In some cases, yes this may work!  But only under certain combinations of conditions. 

It’s ok to have a regular checkpoint to see if your houseplants need water or not, but you shouldn’t blindly water a houseplant just because your schedule tells you to. 

If you watered a plant, and a week later the top of the soil is still moist, you should NOT water it again.  Doing so will invite root-rot.

When a plant stays too wet, you are depriving the roots of oxygen and they will proceed to rot.  As a general rule of thumb, you should wait to water until the top inch or two of the soil is dry (depending on the size of the pot). 

Then go ahead and give it a good soaking.  There are some exceptions though.  Some plants, such as succulents or cacti, should be allowed to go completely dry before watering again…but don’t wait TOO long!

The concept of “overwatering” houseplants is very rampant and it doesn’t necessarily mean what you think! Check out my blog post on overwatering and find out what it really means.

Myth #3:  You Water Orchids with Ice

NO!  Unless you’ve seen a monkey with a popsicle in the jungle, then you should not water your orchids with ice.  This is one of the worst marketing gimmicks I’ve ever seen. 

Do NOT use ice to water your orchids.  First of all, when the ice melts, it does not provide enough water in order to soak the potting medium and thoroughly moisten all the orchid roots. 

Secondly, the ice can damage the roots if they come into direct contact with the ice.  It makes absolutely zero sense to water orchids with ice. 

This scheme is mainly marketed for Phalaenopsis or moth orchids.  Phalaenopsis come from the tropics of southeast Asia and I guarantee you they’ve never met an ice cube.

Myth #4:  If I fuss over my houseplants, they’ll grow better

Don’t get too happy with that watering can!   You have to let nature take its course and a lot of people tend to overwater their houseplants. 

Like I mentioned, it’s OK to have a regular checkpoint to see if your plants need water, but don’t water just because you told yourself you need to water every Saturday. 

I can’t emphasize the following point enough:  If your calendar is telling you that it’s your normal watering time, and you feel the surface of the soil and it is still moist, then don’t water! 

On the other hand, you might find a houseplant that dried out terribly and once a week may not be enough.  You may need a couple checkpoints during the week. 

Why is this?  Watering needs vary drastically depending on:

Temperature:  Higher temperatures means that soil will dry out more quickly.

Pot Size:  Smaller pots will dry out much more quickly.

Pot MaterialTerra cotta pots will dry out very quickly because they are porous.  Plastic or glazed ceramic pots will take longer to dry out. 

Choosing a pot type based off of your specific plant can work to your advantage or disadvantage, so choose carefully depending on the moisture needs of your plant.

Growing Season:  Depending on where you live, plants will slow down or stop growing in the middle of a dark/cold winter. 

So they will not use as much water and you have to be careful not to “overwater” especially during this time.  On the other hand, during the growing season, plants will use more water.

Root System Size:  Recently I was shocked because I had watered my large hibiscus tree indoors in the middle of winter, and 3-4 days later, it was very dry. 

This plant has an extensive root system and is in a large pot.  I probably won’t be repotting that plant anymore otherwise it’ll be too difficult to move. 

Having a pot-bound plant, coupled with increasing growth as days are getting longer, all increase the need for watering.

Humidity:  In a more humid atmosphere, soil will generally take longer to dry.

Light Levels:  The higher the light levels, the more water a plant will use.  A plant that is sitting in a dark corner will use much less water than a plant that is in brighter light that is actively photosynthesizing and growing.

Myth #5:  Everything on the internet is true

WRONG!  This one is a BIG WRONG.  You can tell the websites that just regurgitate material versus those that truly have knowledge to back it up. 

Be weary of any old website, or many sources on social media, when getting houseplant care information especially when it seems vague and generalized. 

I’ve seen so much misinformation online.  So if you are researching online, trust reputable sources (such as Ohio Tropics!)  Or if you have very specific questions, it is best to refer to the numerous plant societies out there such as:

So there you have it!  Hopefully you have taken away some helpful pointers in houseplant watering.  Did you read anything here that was new information for you?  If so, comment below!

I would like some information on Hoya soil please. I bought a Hindu rope at Walmart and it was soak in water. So I waited about three weeks to water again and the leaf starter turning yellow Ana eventually the plant dye. So indeed some tips in case I get another one

Here is a blog post I wrote on Hoya carnosa, but the same care and soil would apply to your hindu rope:

hi! thank you so much for your blog posts on plants! i find them really useful and credible! i'm very new to growing indoor plants and i'm scared i might kill them in a week! but i made sure i got low light growth plants and have been reading about watering plants here in your blog. very informative! however, when do i start giving my new plants fertiliser? also, i live in the Philippines and can't buy the dyna-gro grow. any brand that you recommend that you think is being distributed here? or instead of a brand, what ingredients in the fertiliser should i look for? i was actually given urea crystals by the plant supplier but as you've said, this is not a good type of fertiliser.


Tuesday 12th of May 2020

Hi Patricia. Do you have any organic fertilizers available? Fish and seaweed fertilizers are also great, but I only like to use these outside. The fish emulsion has a smell to it...I haven't used urea crystal, but I would be careful of those. Any all-purpose houseplant fertilizer should be ok. Some are better than others, but see what you can get your hands on where you live!

As an addition - are you saying that my plants' soil should just be dry on the upper third or so? Also I am trying my hand (again) at a maidenhair fern and a phaleonopsis. The ones I purchased at Trader Joe's died fairly quickly because they were planted directly into the ceramic pot. This time I purchased elsewhere and saw that there was a plastic drainage cup inside the ceramic pot. I will remove the mossy fru-fru at the top before watering, as you said. The maidenhair is in my kitchen just out of the sunlight (I have a garden window). Two days ago I moved it behind some plants about a yard from the window and a few of its leaves started to get discolored. Back in its original place, it looks pretty good. I have only watered it once, when kind of dry damp.

Hi Deborah! Feel free to use the search feature on my site. I have a lot of blog posts on many plants, and am continually adding more. Maidenhair ferns need to be continually moist. I wrote a detailed blog post on them (see the link at the end of this comment.) I also have a lot of posts on orchids. Type in orchid in the search feature of my site and you will find several posts :-). Here is my maidenhair fern post for your convenience:
