How Do You Care for Hoya Linearis? 8 Important Growing Tips

Some of the links in this post may be affiliate links.

Hoya linearis is another super hot plant that growers can’t keep up with demand. There are many types of Hoya out there that are much more commonly available, but Hoya linearis is distinctly unique and quite a bit different.

Challenging to find, they are also reportedly one of the most challenging Hoyas to grow, but I’ve found them to be easy! It is all about knowing what each plant species likes.

If you can give it what it likes, it will be a cinch to grow! Let me show you how I take care of mine.

Where Hoya Linearis Grows

Before I go into how exactly I care for my Hoya linearis, I would like to introduce where this plant grows in nature.

If you can approach the conditions that this plant grows in nature, you will have no problems growing this plant.

This plant grows as an epiphyte (on trees) in the Himalayan region in Northern India and in the nearby vicinity. It actually grows on trees in higher altitudes, and dangles down similar to how Spanish moss grows.

If you can gather from the region that it grows in, it does prefer cooler nighttime temperatures as compared to some other types of Hoyas.

How to Grow Hoya Linearis

This plant is different from many other hoyas in that it doesn’t have large, firm, waxy leaves. Instead, the leaves are skinny, soft, and slightly hairy. It really has a lovely growing habit.

They also will give you white, star-shaped flowers that reported have a lemon scent to them. Mine has not flowered yet, but I will update my post when it does to show you.

Take a look at the difference between my Hoya linearis below…

Compared to my Hoya carnosa below…

In my experience so far with growing this plant, despite the rumors and hype that you may have heard that Hoya linearis is one of the more difficult hoyas, I’ve had no troubles at all!

I strongly believe that this is because I am providing the right conditions for this plant. So what are the conditions that it likes?

Let’s talk about that a little bit, and you’ll want to read ALL of this post because you can’t just get one thing right when it comes to houseplant care. A number of combinations working together will give you true, lasting results.

There are NO shortcuts or magic buttons to houseplant care!


Improper watering and soil moisture conditions is probably one of the most common downfalls in houseplant care.

This is especially the case with Hoya linearis. These are very easy plants as long as you keep the soil on the dry side (but at the same time, you need proper watering habits)!

I do my best to teach people about my watering methods so let me elaborate more on this. Like all hoyas, these plants like to dry out well between watering.

This does NOT mean that when you water, that you’d only want to add a tiny bit of water. So many people are scared of overwatering, but it is a very misunderstood term! Always water thoroughly.

I preach a holistic view on houseplant care. You can’t just get one thing right, and have complete disregard for everything else.

Good watering practices are paramount.

When you water, you should thoroughly soak the potting media. Water until all the soil is saturated and all excess water drains away through the drainage hole. ALWAYS have a drainage hole!

This is especially important for epiphytes, like Hoya linearis, which literally grows hanging on trees. They DEMAND excellent drainage and this is apparent because of how they grow in nature.

Like any hoya though, they like to dry out between watering. So allow the entire potting mix to dry out before you consider watering again.

On that note, feel the potting mix with your finger to know when it is dry. Pick up the pot and also notice when it is very light. You will get to know when the soil has completely dried out.

I strongly caution against the usage of water meters. I’ve known so many people that have devastated their plants because they trust the water meter too much in order to tell them when to water.

Think about it, many epiphytes will get poured on by heavy rains (the entire plant is thoroughly soaked), but since they are epiphytes (growing on trees and exposed to a lot of air circulation), they will dry quickly.

In the winter, you can go even longer in between watering since reduced light and perhaps cooler temperatures indoors will slow down, or even halt, growth.

Watch out for signs of stress. You don’t want to push it too far that the plant is stressed and becomes shriveled or dried out.

This brings us to the next point which you NEED to have for hoyas.


Hoyas in general like smaller pots and like to be root bound. My own plant came in a tiny pot and I will leave it in there for quite a while.

As a general rule of thumb, Hoyas need repotting much less frequently than other plants and are content to be in the same pot for years.

Remember the Hoya carnosa I showed you in the picture earlier in this post? I’ve had it in the same pot for over 15 years and it is thriving!

If you’d like to read about how I care for that plant, be sure to check out my blog post on Hoya carnosa for growing tips.


If it comes time to repot a hoya, only go up by one pot size. These plants despise being over-potted and are content in smaller pots for long periods of time.

Take my own Hoya linearis plant below.

When I received it, it was in a 5 inch diameter pot and I’ve kept it in there for over two years. I have no plans of repotting it at all because it is still growing beautifully and is showing no indications of slowing down.

Keeping Hoyas pretty root bound will also help to encourage flowering as well, so this is another plus!

I will not repot this plant until I notice the growth has slowed down and I’m having trouble keeping the potting mix hydrated enough. This will likely indicate that the pot is full of roots, so I would gently take the root ball out of the pot to inspect and see if it necessary at that point. Heavily root bound plants will have roots circled around the bottom.

In general, you can keep hoyas in the same for many years and they enjoy pot bound conditions.


As far as potting mixes go, light and airy is the way to go. You have a few options that you can use for Hoya linearis, or any hoya for that matter.

A good succulent or cactus mix, to which you add some perlite would make a wonderful mix for this plant. Remember, sharp drainage is important for any plant, but especially for epiphytes.

Horticulture magazine recommends 2 parts of a soilless mix to 1 part of fine-grain bark mix and a good mix for epiphytic plants in general (please don’t use this mix for moth orchids though!). This mix is very appropriate for hoyas.

If you don’t have fine-grain bark mix, you can substitute perlite. I tend to use a good cactus/succulent potting mix and add perlite. Experiment to see what works for you. This blend has worked very well for me.

I always have a succulent mix and perlite on hand myself so I typically use those for most of my houseplants.

I buy the following from Amazon to make my blends:

Miracle Gro Cactus, Palm and Citrus Potting mix


Espoma Organic Perlite

LIGHT! Another super important topic. I have my own Hoya linearis in my sunroom in the corner of a North window and East facing window.

When the sun does decide to come out in Ohio, it does receive morning sun 🙂 . Be sure to keep this plant right in front of a window for best results, and if you can give it morning sunshine, it will greatly benefit this plant, especially in the winter time.

I know it may seem so basic to do this, but you’d be surprised how many people I have to remind that they should have plants right in front of a window for best results.

If you do live in warmer regions, be careful of too much sun, especially extended periods of strong sun. This is a cooler growing species.

As a general rule for houseplants, make sure your minimum nighttime temperature doesn’t go much below 55F.

During the summertime, depending on where you situate your plant, you may want to diffuse the direct sunshine a bit. Just keep an eye on your plant and it will tell you if it doesn’t like something.

And remember, having Hoya linearis in appropriate lighting will help the potting medium to dry out more quickly, which is absolutely critical for this plant.


To keep things simple, I have greatly simplified my fertilizing routine and pretty much consolidated to one fertilizer. It is readily available on Amazon.

I use Dyna-Gro Grow fertilizer and have had great results with all of my houseplants! It’s an amazing all-purpose, urea-free, complete fertilizer that contains all the major micro and macro nutrients that plants need to thrive.

It has become my go-to all-purpose fertilizer that I use for most of my plants (because it works really well and I’m lazy and like to consolidate!)

I simply mix 1/4 teaspoon into a gallon of water, and use it every time I water (or try to at least) during the growing season.

You can mix it as you go, or prepare the solution in a gallon jug to use whenever you need it.

As a general rule, I don’t fertilize any of my plants from about October through February or so. When I notice plants perking up in February or March, I will slowly start my Dyna-Gro Grow fertilizer routine.

Remember that the key to growing Hoya linearis is allowing its potting mix to dry out completely fairly quickly in between through watering. This can only be achieved by a combination of good light, small pot size, and an appropriate potting mix.


Hoya linearis does enjoy higher humidity, but honestly, I’ve found that average indoor humidity is sufficient.

I do run my humidifier though in the wintertime when my indoor air is very dry.

If you can maintain at least 50% humidity, your plant will enjoy that. If you need tips on this subject, check out my detailed blog post on how to increase humidity.

Remember that misting does NOT increase the humidity in the air, but since this is an epiphyte, it will benefit from misting. When I take my plant to the bathroom to give it a good watering, I also wet the foliage.


Being a higher altitude Hoya, this plant can handle pretty cool nighttime temperatures. To be safe, don’t allow minimum temperatures to go below 15F (10C).

In general, try and maintain daytime temperatures between 60-80F (16-27C) for best growth.


Eventually, if your plant likes your conditions, it can get extremely long! My plant reached over 6 feet long before I gave it a trim and used the cuttings for propagation.

When you trim your plant, just be careful not to cut the flowering spurs, or peduncles, if you can avoid it. The flowers will emerge from the same peduncles each time it blooms.


Clusters of fragrant, start shaped flowers, characteristic of many Hoyas appear typically in late summer or Autumn and can easily last at least 2 weeks.

Here are two photos of my Hoya linearis flowering.


The flowers have a wonderfully sweet fragrance, and remind me a little of cinnamon with a touch of lemon.


What are some factors that encourage blooming?

  • Enough light is the top concern.
  • Age (you must have a mature plant that is at least 2-3 years old)
  • Root bound conditions often encourage Hoyas to bloom.
  • A dry rest period of a few weeks will often help trigger flowering.

I can tell you from personal experience that providing enough light is the number 1 reason why Hoyas don’t flower.

My linearis didn’t bloom indoors for years simply because I didn’t have it in a location with enough light. Once I moved it into my greenhouse, it rewarded me with plentiful blooms.


I’ve known people to propagate these plants in water. You can certainly do so, but let me discuss what the International Hoya Association recommends for Hoya propagation.

  • Take stem cuttings and ensure that each cutting has 2 or 3 nodes (where the leaf meets the stem).
  • Remove the leaf from at least one of the lowest nodes.
  • Dip the end into a rooting hormone, and insert each cutting into a pot. The IHA recommends using soilless mixture to which you add 30-40% perlite.
  • Water the soil and make sure it drains. Don’t allow the soil to dry completely. Conversely, don’t let the pot sit in standing water.

I use Garden Safe TakeRoot rooting hormone which I get on Amazon.

If you are able to increase humidity while the plant is rooting, this can be very beneficial. You can place the pot in a clear plastic bag to increase humidity. Keep it out of direct sunlight though while it is rooting so that you don’t cook your cuttings!

The clear plastic bag can help you keep humidity high while it is rooting, but these plants also like to generally grow in higher humidity.

I wrote a blog post on the topic of humidity and I also talk about my favorite humidifier. I’ve tested many humidifiers and this one is by far my favorite!

To check it out, be sure to read my humidity blog post. This is especially important during the winter months when dry air can be big issue!

Why is my plant dropping leaves?

Cold drafts can often cause this, as can keeping your plant too dry for extended periods of time.

Why is there a large distance between leaves?

This is simply due to insufficient light. My own plant currently grows right under a skylight. After it had reached a few feet long, the internodes (distance between leaves) was larger. This is simply because the base of the plant was not receiving as much light as the top of the plant.

Are Hoyas toxic?

Hoyas are considered non-toxic, but Hoya linearis has a white, milky sap that it exudes when you cut or break a leaf or stem. This sap can irritate your skin.

Why is my plant not blooming?

There are multiple factors that influence blooming. The top reason is light. You can also encourage blooming by keeping your plant pot bound and introducing a dry period of a few weeks right before the blooming season.

Why are my leaves shriveled?

This is likely due to improper soil moisture. Feel your potting mix. Is it bone dry? If so, this likely caused your plant to develop shriveled leaves, so go ahead and water.

If your potting mix has stayed wet for a long time (due to sitting in water, or other reasons), it may have started to rot. Check out the root system, and if you detect root rot, it is probably best to start propagating your plant and start out fresh again so you can save your plant.

What do I do if I see mealy bugs on my plant?

I like to use a good insecticidal soap to eradicate mealybugs. Be sure to spray the entire plant down entirely and repeat weekly. You should repeat even AFTER you don’t notice mealybugs anymore for a week or two. This will ensure that you took care of all of them. Check out my post on treating for mealybugs for all the details.

Hi Raffaele. This is a wonderfully informative post, thank you, and I've signed up to your newsletter for more tips! I've only had my Hoya Linearis for a few months, and it is doing well and has flowered (though the flowers have now dropped off as we approach winter). I have noticed that there seems to be some moss in the pot with the plant - I bought it from a garden centre, so may be that this has been there a little while. Do you expect this will cause the plant any problems? If so is there a best way to remove it/prevent regrowth? Thanks so much!


Thursday 1st of December 2022

Hi Hayley! Glad you enjoyed the post and thanks for subscribing! I hope you'll find it useful :-). I wouldn't worry about the moss much. As long as your plant is doing ok, keep doing what you're doing.

Good morning Raffaele, your post was very helpful taught me quite a bit. I have a smaller collection of hoyas considering how many different beautiful species their is.. They are very similar in caring needs for most. How fast would you say your linearis should dry out before watering again, how many days would you say thats considering you have the right pot size and mix. Pls help would you recommend a hydroponic plastic pot. I have one of my other hoyas in one are its doing great... Thank you. How can I send a picture?

Hi Jennifer! Do you mean a self-watering pot?


Monday 9th of May 2022

Hi Raffaele, I read your post on Hoya Linearis and found it very informative and interesting. I wanted to ask you if you think a good solution for the soil could be bonsai soil, thanks!


Monday 9th of May 2022

Hi Rossella! Yes, that would be an interesting option and could work well as long as you can maintain the moisture requirements of your plant. If you're switching substrates, always keep an eye on it and adjust your watering as needed. :-)
