Polka Dot Plant (Hypoestes phyllostachya Baker) Care & Propagation Guide
How to grow Polka Dot Plant (Hypoestes phyllostachya Baker)? In fact, Polka Dot Plant is easy to grow, as long as we find the right way and care tips. The following will introduce Polka Dot Plant care & propagation tips in detail. The plant height of Polka Dot Plant (Hypoestes Phyllostachys Baker) can reach about 30~60 cm, but the potted plants are usually controlled within 10-15 cm. The leaf surface is olive green with red, pink or white spots on it. It can bloom in spring, the flowers are small and inconspicuous, and they are lavender small spike-like flowers.

Polka Dot Plant Propagation

Polka Dot Plant Propagation with Seeds

When you are propagating polka dot plants (Hypoestes Phyllostachys) by seed, if you don't already have them on hand, allow the seedheads to dry on the plant and then remove. Once you have collected the seeds and stored them until planting time, sow them in a tray or pot filled with damp peat moss and perlite or a well-draining potting mix. This should be done prior to the last expected frost in spring or sometime in summer. The polka dot plant seeds require warm temperatures to germinate (around 70-75 F. or 21-24 C.) and will do so within about two weeks given adequate conditions. It usually helps to add a clear plastic covering over the tray or pot to hold in both heat and moisture. This should be placed in indirect sunlight. Once established and strong enough, they can be repotted or planted outdoors in a partially shaded area with well-draining soil.

Polka Dot Plant Propagation with Stem Cuttings

This is the main method of propagating Polka Dot Plants (Hypoestes Phyllostachys) as it’s suitable for all maturities. It’s also really easy to get right as you can create several new Polka Dot Plants just by taking a few small cuttings
  • Locate some healthy Polka Dot stems
 When taking a vine cutting you want to make sure that the part of the plant you are cutting is healthy to give you any chance of success. Avoid any sign of disease or pests as they will be transferred onto your new cuttings and may make it harder for the cuttings to grow into proper plants.
 When taking cuttings to propagate your Polka Dot Plant, you need to check for one important thing; a node. Without it, you will have a very slim chance of a successful propagation. A node is where a leaf has grown from the stem.
  •  Make the cut
Use your clean scissors to cut off one or more stems. You want to make sure that you have at least 2-3 leaves on your cutting as this ensures you have a few good nodes from which roots can grow out from.
Keeping your tools clean avoids passing on bacteria or pests to your plant and also is important when dealing with toxic plants. (Although Polka Dot Plants are largely non-toxic, it’s a good habit to get yourself into)
  • Fill up a transparent container with water
Now that you have taken your cuttings, you need to grow them in something. You can pot them directly into soil as Polka Dot Plants grow roots very quickly but we always recommend water as a middle step. It just has a better success rate.
Fill up your container with temperate water (so as not to shock your delicate cuttings) and place your cuttings in so that the lowest third is covered by the water. Covering any more of the cutting increases the chance it will rot. If any leaves will be in contact with the water then remove them at this step as they will start to rot after being submerged for a few days.
We always prefer to use a clear container when propagating as you can see everything a little clearer.
  •  Place your cuttings in bright but indirect light
It's super important your cuttings aren't exposed to direct light as it will very quickly burn the cutting and prevent a successful propagation.
  • Change out the water regularly
One of the most important steps in the Polka Dot Plant propagation process is to refresh the water regularly (every 2-3 days is optimal). This keeps the water free from bacteria and stops it from stagnating which is harmful to your cutting. Stagnant water will also start to smell so it’s best to avoid this!
  • Be patient
Luckily Polka Dot Plant cuttings grow roots pretty quickly so you should start to see two delicate roots pop out from the node after only a few days. It can be a little unpredictable though and some cuttings will be a lot faster than others. But the process is definitely a lot quicker than with some other common houseplants, where you can be waiting months for anything to happen.
The benefit of Polka Dot Plants growing roots so quickly is that there is less time for something to go wrong and the risk of root rot is significantly reduced.
  • Plant your Polka Dot cuttings into fresh potting mix
Once the roots on your Polka Dot cuttings are a few centimetres long it’s time to pot them into soil. Don’t worry if the roots are still very delicate, this is normal for Polka Dot plants so just be a little careful when potting them to make sure they don’t break.
We recommend using a high-quality potting mix to make sure your cuttings are getting the right mix of nutrients. Carefully place your cuttings a few centimetres into the soil. You can also pop the cuttings back into the mother plant so it becomes a little fuller – it’s up to you!
  • Resume usual Polka Dot Plant care
Now that your cuttings are pot nicely into soil, you can go back to your usual Polka Dot Plant care routine and soon those plants will be big enough to propagate again and you'll end up with way more Polka Dot Plants than you could ever need.

Polka Dot Plant Propagation with Division

This method of propagation only really works if your Polka Dot Plant (Hypoestes Phyllostachys) is quite bushy, otherwise, they can be left looking a little straggly. If you do have a big enough Polka Dot Plant that you don't mind dividing then this method is great for those who don’t want to wait for new roots and leaves to grow – instead, you get new plants instantly!
  • Take your Polka Dot Plant out of its pot
To be able to propagate your Polka Dot Plant through the division method, you need to separate the different offshoots/stems. This is particularly easy to do with Polka Dot Plants compared to some other plants as they separate easily.
The first step is to carefully lift your plant out of its pot. Don't tug too hard at the leaves as they are quite delicate but slowly shimmy the plant out of the pot.  
  • Separate out the plant
You may have to trim off the odd root to detangle the plant but you should be able to pull the various parts of the plant apart. Each section should have some roots attached so inspect these carefully to make sure there aren’t any obvious problems (mushy rotted roots is the main one you are looking out for here).
How many new plants you want to create is completely up to you and totally depends on your mother plant.
  • Place each new plant in fresh potting mix
Pop your mother Polka Dot Plant back into its original pot (or downsize slightly if you have taken away a substantial amount of the original plant). Then pot your new plant(s) into fresh potting mix. Make sure not to reuse old potting mix from other plants as there may be bad bacteria or pests lingering in it that will start to impact the health of your new plants.
  • Continue normal Polka Dot Plant care
That's all there is to the division propagation method of Polka Dot Plants. Now that your plants are safely in their new homes, continue with your normal Polka Dot Plant care routine!

Polka Dot Plant Care

Polka Dot Plant Care - Light

To keep the colors of Polka Dot plant leaves bright and vibrant good light conditions are a must.
Bright, indirect light will work best for Polka dot plant. Indoors, a spot near a window with morning sun will give your plant a good amount of healthy sunlight. Whichever direction your windows are facing, too much light may hurt your plant. If the sun is too strong you can diffuse the light. Provide a sheer curtain for your plant to soften the light it receives. 
Artificial light from grow lights can also work if you do not have a bright place you can put your plant in. When given enough light, Polka dot plants can produce flowers. It will be up to you if you will cut the flowers or keep them. Keep in mind that flowers can cause the plant to be leggy as it expends too much energy on allowing them to bloom.
Another reason for the plant being too leggy is lack of light. The leaves of the plant tend to reach out for places with better lighting.

Polka Dot Plant Care - Soil

Polka dot plants tend to do best in nutrient-rich, well-draining soil. It doesn’t have to be complicated and you can easily mix your own! For example, you can use general potting soil mixed with perlite for drainage and throw in a layer of compost for extra nutrients.

Polka Dot Plant Care - Watering

The polka dot plant requires moist soil but not soggy. If it dries out too much, it will begin to wilt and keel over. A quick watering will usually help it to spring right back. Avoid allowing your polka dot plant to sit in water as it will cause root rot. Water well when the top ½ to 1 inch of soil has dried out. Also remember that smaller sized planters will dry out more quickly than larger sized planters. Make sure that you’re watering the plant from the soil level and not from the top as the water on the foliage may cause water spots and damage to the tender leaves and flowers.

Polka Dot Plant Care - Temperature & Humidity

The air humidity of your home is what determines if this your Polka dot plant care will be easy or not. Polka dot plants prefer to be in a humid environment. A minimum level of 50% humidity will keep the plant happy, but more is better. They will tolerate lower humidity if they are happy with other things in their plant life.
If you see your Polka dot plant struggling – drooping leaves often, leaves drying, brown tips, we recommend placing it in a terrarium. They make excellent terrarium plants, and they will thrive in an enclosure.
Hypoestes Phyllostachys are plants that are native to temperate countries. This means that they thrive better under warm temperatures. Ideally, your plants will grow well and show vibrant colors in 70°F to 80°F (20 to 27°C.). Lower room temperatures are OK too. They won’t tolerate too much cold air, especially frost. When grown indoors, keep away from cold drafts.

Polka Dot Plant Care - Fertilizer

If you want your polka dot plants looking their best, they benefit from being fed once a month during the growing season. After all, these guys are pretty quick growers.
A diluted liquid houseplant fertilizer is typically enough to do the job. As mentioned above, you can also use a bit of compost for the extra nutrients.
If you notice the very tips of the leaves becoming brown and crispy, you may be using too much fertilizer. Luckily, you can just flush the soil with some distilled water, snip off the affected leaf and carry on from there. No panic, just adjust your care as you go along.

Polka Dot Plant Care - Pruning

Polka dot plants (Hypoestes Phyllostachys) grow quickly and tend to get leggy without regular pruning. To encourage fuller growth and maintain the desired shape and size, pinch back the stem tips periodically throughout the growing season. Also pinch off any flower spikes that may develop. They offer little ornamental value and will detract from the foliage.

Polka Dot Plant Care - Pests & Diseases

Watch out for scale, whiteflies, mealy bugs, and aphids on your polka dot plants.2 You might notice foliage that's discolored, has holes, or otherwise appears unhealthy, along with small bugs moving on the plants. Plants grown indoors under suboptimal conditions typically have more problems with pests and diseases than those grown outside in the correct environment.

Varieties of Polka Dot Plant (Hypoestes phyllostachya)

Within the main species, Hypoestes Phyllostachys, there are many varieties; all are bred for their leaf coloration. They include:
‘Camina’: Dark green and red-spotted leaves
‘Confetti’: Leaves in green and spots of white, pink, rose, red, or burgundy
‘Pink Brocade’: Green leaves with mottled pink spots
‘Splash’ series: Leaves in mixes of greens with splotches of pinks, reds, or whites

Polka Dot Plant (Hypoestes phyllostachya) FAQ

 Can I Place My Polka Dot Plant Outdoors In Warmer Weather?

Just as many other houseplants, the polka dot plant (Hypoestes Phyllostachys) does very well outside in a shady location during the warmer months. Bring it indoors if the temperatures are going to drop below 60 °F. Also avoid allowing it to become too hot and keep it in temperatures below 75 °F.

Does The Polka Dot Plant Ever Grow Outdoors Exclusively?

It its home regions of South Africa, East Asia, and Madagascar, the plant is frequently grown outdoors. When grown outdoors it may become as tall as three feet. It does, however, adapt itself well to indoor living and will provide a delightful addition to any collection of houseplants. Make sure to keep it out of too much sunlight and don’t over water your polka dot plant.

Does The Polka Dot Plant Require Any Special Care?

While the polka dot plant doesn't require a lot of specialized care, it will tend to become leggy if it's grown in the proper low lighting. This is due to the plant reaching out for more light however, the light will cause the plant to fade and your “polka dots” will become lighter in color if the plant is in too much light.
