Hoyas are among my favorite houseplants. They are tons of varieties, are easy to grow, tolerate neglect, and are great for the beginner or experienced houseplant enthusiast alike! Hindu Rope Hoya, or Hoya carnosa, is a unique Hoya with crinkled, tightly packed leaves. You may also hear some people refer to the plant as Krinkle Kurl.
In this post, I’ll give you all my growing tips for this unusual houseplant, as well as answer some of the common concerns with this plant, so keep reading!
There are both plain green varieties as well as an incredible variegated version.
Here is the plain green version that is in bloom and is incredibly gorgeous in its own right!
And check out this variegated Hindu Rope. It’s absolutely stunning! I love the yellow and pinkish variegated leaves.
HINDU ROPE HOYA CARE
These plants need quite a bit of light in order to really do their best. They are really slow growers, so if you are impatient, I would recommend purchasing a large plant to start with!
Even in great lighting conditions, they may only grow a few inches a year. For best growth, they need a few hours of sun every day. A few hours of morning sun, or afternoon sun would be preferable.
If you live in areas with really strong sun, try and avoid mid-day sun. Also, keeping these plants in full sun all day may cause the foliage to bleach out and turn pale. Partial sun will result in much better leaf color.
I have my own plant hanging right under a skylight in my sunroom and it receives some direct sun.
Having enough light is also important for flowering, and Hindu Rope Hoya has the characteristic, fragrant Hoya flowers. Aren’t they gorgeous?
If you keep your plant in darker conditions, not only will you be disappointed with really slow growth (they are already slow growing to begin with, even in great light!) but they will also likely never flower.
2. WATERING and FERTILIZER
Watering is an important aspect of growing Hoyas. Always water thoroughly and moisten all of the soil, let excess water drain out, and don’t allow your plant to sit in water.
Keeping plants wet for long periods of time will encourage root rot in Hoyas, so be sure to allow your soil to go completely dry in between watering.
Hoyas are epiphytic plants, meaning that they grow on other plants (such as on tree trunks or branches), so they go through periods of being completely soaked, but then dry out quickly in between.
Keeping this in mind is important to understand their care!
If you are away from home a lot or travel a lot for weeks at a time, Hoyas are ideal! They can easily go 2-3 weeks without any sign of stress in most cases.
As far as fertilizing, refrain from using fertilizer in the winter when growth has stopped or is very slow, but I do fertilize my Hoyas the rest of the year.
My favorite all-purpose houseplant fertilizer that I use is called Dyna-Gro Grow.
It is simply amazing stuff. It is urea-free so you won’t burn your plants if you use it per the instructions on the label.
It is also a premium fertilizer that has all the macro and micro nutrients that plants need for growth. I’ve achieved great results and you can too with a consistent regiment!
I can’t recommend Dyna-Gro Grow enough. I use it for all my houseplants except succulents.
Hoyas like an airy soil that dries out quickly. I would recommend using two parts of your favorite potting soil (I like Miracle Gro or Espoma potting mixes) to which you would add 1 part of an amendment. You can easily find everything on Amazon.
To the two parts of soil, mix in one part of perlite, pumice or even orchid bark. Depending on what I have handy, I may change what I use. The important part though is that you want excellent drainage.
4. TEMPERATURE and HUMIDITY
Hindu Rope Hoyas prefer minimum temperatures of at least 60F and above, with warmer daytime temperatures.
Most hoyas grow in warm and humid tropical regions. (There are some that grow in higher elevations like Hoya linearis, but the majority of Hoyas like it warmer).
Like any epiphyte, Hoyas like high humidity and the plants actually absorb moisture from the air. That being said, they are tolerant of average indoor humidity, but if you can increase humidity, it is absolutely helpful!
Be sure to check out my blog post on the best ways to increase humidity for your houseplants. Some of the information may surprise you! I also talk about the most effective method to increase humidity.
5. POT SIZE AND TYPE
Pot size and type are both very important when growing any Hoya. Remember that these plants are epiphytes and need to be able to dry out quickly in between watering.
Don’t make the mistake of overpotting these plants. They can live happily in the same pot for years and they like to be root bound. In fact, this also is a contributing factor in encouraging them to bloom (having enough light is probably the most important factor though).
When you do move to a bigger pot, only go up one size. For example, if you have one in a 4 inch pot, don’t go any larger than a 6 inch pot.
As far as the type of pot goes, I like to grow my hoyas in terra cotta (clay) pots when I can.
Terra cotta pots dry out very quickly and this is so important to encourage a healthy root system for your Hoya.
If you’d like to learn more about these pots, check out my blog post about the pros and cons of terra cotta pots.
Because of the crinkly leaves, dealing with pests can be tricky with these plants. Just take a look at the places they can hide!
Hindu rope Hoyas are very prone to mealy bugs and it can be tricky to detect them at first because they have so many places to hide in the contorted leaves.
As soon as you detect them, start a spraying regimen.
I would recommend using Neem Oil or Insecticidal soap on a weekly basis. In the middle of each week in between spraying, be sure to rinse the plant off to remove any residue so that it doesn’t harm the plant.
Keep repeating weekly even after you don’t see any mealy bugs anymore. This will ensure that they are gone.
You’ll want to treat your plant not only for the sake of your Hoya, but also so the mealy bugs don’t spread to your other houseplants. Pests can quickly go out of control when left unchecked!
These are both safe and naturally derived products, but please be sure to use it according to the label.
Propagation is simple. Simply take a cutting that has 3 or 4 leaves. Take the bottom leaf off, and place it right into a small pot of soil.
If you want a fuller plant, place multiple cuttings in the same pot.
It helps to keep the soil relatively moist as rooting is occurring. Keeping them in a warm area and increasing humidity will also speed the process up.
You may want to consider placing your rooting cuttings in a clear plastic bag to keep the humidity high until your cuttings are rooted.
Hindu rope plant is non-toxic to cats and dogs according to the ASPCA.
