Peperomia Marble

The Peperomia Marble is also known as the Variegated Baby Rubber Plant. And it is a sport of the popular Peperomia obtusifolia, which makes its complete botanical name Peperomia obtusifolia ‘Marble’.

This is one of my daughter’s favorite plants because of its beautiful foliage. Its small size also lets her conveniently carry it around when needed and take care of.

Speaking of which, as gorgeous as it looks, the Peperomia Marble is actually very easy to care for. Thus, making it perfect for beginners.

Of course, the most attractive feature of the plant are its spoon shaped green leaves with yellow-cream marbling. These leaves are likewise thick and fleshy making them succulent-like.

That said, do note that the plant is not a succulent. Instead, it is semi-succulent, which means that it has certain features similar to that of succulents (but other features that are not the same).

Because it is native to the Caribbean, South America and parts of Mexico, and Florida, the Peperomia Marble easily adapts to home environments.

So, if you like cute, adorable and pretty looking foliage plants, this is a must have in your collection.

Peperomia Marble Plant Care

Light Requirements

The Peperomia Marble thrives on bright, indirect light. It likes well-lit locations because the plant relies on sufficient light to stay healthy.

Therefore, you want to give it at least moderate light to keep it healthy, grow well, produce more leaves of good size. Similarly, the color of its leaves is affected by how much light it receives.

In general, the Peperomia Marble are more tolerant of bright light compared to those with solid green leaves. But you still want to keep it away from direct sun and intense light because it cannot tolerate long periods of exposure.

If left under these conditions, its leaves will get discolored and even experience sunburn.

On the other hand, the plant is also able to tolerate low light and shade.

However, you want to be wary of too little light since this will cause the plant to lose its variegations.

Therefore, an east, west or south facing windows work best. But you want to treat each differently.

  • East facing window – you can keep the plant near the window because the morning sun is gentle (which the Peperomia Marble can tolerate).
  • West facing window – keep the plant a few feet away or use something to filter the light. You want o avoid the sun’s rays from 12:00 noon to 3:30 p.m. in this direction.
  • South facing window – this location has the most light. It also gets the hottest times of the day (10:30 a.m. to 3:30 p.m.). Therefore, you can keep the plant a good distance away (10-12 feet) and still get enough light to keep the plant healthy and happy. But avoid letting the sun’s rays hit the plant.

 

Temperature

The Peperomia Marble is native to the Caribbean, Central and South America. You’ll also see it in Florida quite a bit. The one thing all these locations have in common is their weather.

They have sunshine all year round and the weather is generally moderate to hot.

As such, this is the kind of climate that the Peperomia Marble enjoys (and is used to).

Outdoors, it is well-suited to USDA Hardiness Zones 10 through 12 where you can plant it in the ground or in containers.

Indoors, the plant is more comfortable between 65 and 75 degrees Fahrenheit. As you can guess, it does not have any issues with hotter environments going up to the high 90 degree weather.

However, since it is not used to the cold, you want to watch out for temperatures below 50 degrees. This is where it will struggle. And, the lower the temperature is, the more problems it will encounter.

 

Humidity

The regions listed above all have tropical weather. in addition to being warm, they are also humid.

This makes the Peperomia Marble prefer humid living conditions (50% and higher).

The good news is it adapts quite well to average room humidity and can tolerate dry air as well (despite its preference for high humidity).

More importantly, the plant is not fussy or experiences harm in humidity between 30% and 50%. I haven’t seen any problems with its growth or foliage.

That said, I do recommend trying to keep humidity at 40% and higher. You also want to be more careful with the lower end of that range as you get near 30%.

If you happen to live somewhere with dry air or the summers get very hot and dry, it is a good idea to mist the plant or use a humidifier.

 

How Often to Water Peperomia Marble

The main reason that the Peperomia Marble is able to tolerate lower humidity is because it has succulent-like leaves.

If you look closely, its foliage are thick and fleshy. That’s because they store water to help the plant get through periods of dryness. It also makes the plant a bit drought tolerant.

As such, some growers will squeeze the leaves to know when to water the plant. I have a few friends whoa re very good at feeling for this.

If the leaves feel firm, the plant still has enough water. Therefore, they don’t add water yet.

But once the leaves feel softer or a bit flatter, it is a sign that it needs water.

Anyways, going back to the point.

The reason why I point out its leaves is that while they help the plant fight drought and adapt to lower humidity, its ability to store water there also means that the Peperomia Marble is more susceptible to overwatering.

This compounds the fact that the plant has a small, fragile root system that easily succumbs to too much water.

Thus, you want to be careful with watering too frequently.

Instead, wait for the soil to dry 50% of thew way down before you add more water.

Some of my friends lift the pot to tell whether the soil is still moist or dry. A heavy pot means it still has water while a light pot means it is dry.

If you want something easier you can stick your finger into the soil down to the 2nd knuckle. Then feel your fingertip for moisture. It should feel dry when you take it out. Otherwise, wait a few more days then test again.

 

Peperomia Marble Potting Soil

The best soil for Peperomia Marble is rich, airy and well-draining. This will ensure that the plant does not stand in water for long periods of time. It also allows the roots to get enough oxygen to keep them healthy.

You can use a combination of:

  • 50% potting soil and 50% perlite
  • 50% peat moss and 50% perlite

Depending on whether you have potting soil or peat moss at home. Of course there are other ingredients and combinations you can use as well.

The important thing is to have a component that ensures sufficient drainage. This can be perlite, pumice, coarse sand or orchid bark.

This is important because there are usually 2 sides of overwatering:

  • Watering too often – this is when you water while the soil is still moist. You can remedy this by waiting until 50% of the soil is dry before watering again.
  • Waterlogged soil – heavy soils or those that retain too much water. Even if you water just the right amount and frequency. If the soil holds on to too much water, the roots still end up sitting in liquid. Thus, you need soil to drain this excess moisture.

The final piece of this puzzle is to use a pot with drainage holes. This way, liquid that drains from the soil escapes from the pot (and does not just poot at the bottom).

 

Fertilizer

The Peperomia Marble is a light feeder with low maintenance requirements.

And this applies to fertilizer as well.

All it needs is once a month feeding of a balanced water soluble fertilizer dilute to 50% strength. You only have to apply plant food during spring and summer. Avoid doing so in winter.

If you want to reduce the frequency of applications you can use slow release fertilizer instead. This way you’ll only feed the plant 2 or 3 times a year.

 

Pruning

The Peperomia Obtusifolia Marble is a small plant that can reach between 10 to 14 inches tall and about 6 to 10 inches wide.

It has a more upright growth habit so it will look taller than wider. However, a lot of its looks will ultimately depend on how you prunre it.

In my case, I like leaving in on a tabletop for everyone to see its beautiful colored leaves. Thus, I trim it about once a year with some very minor pruning every so often when I see leaves going wayward.

My goal is to keep it fairly tight together with a full look. I think the plant looks great when bushy so you do want its leaves to get dense (especially since they don’t get messy looking)>

 

How to Propagate Peperomia Marble

Propagating Peperomia Obtusifolia Marble is quite easy and you can use many different methods since the plant roots easily.

This is one of the biggest benefits of peperomia which allows home growers to grow new plants from different parts including leaves or stems.

From the different techniques I’ve tried, the fastest results come from stem and leaf propagation. Of course, you can divide the plant if you want instant results.

Peperomia Marble Leaf Propagation

  • Leaf propagation uses leaf cuttings. Here you have a ton of options.
  • By that I mean you can take the leaf cutting with a petiole, without the petiole, with a part of the stem or even using half-leaves.
  • Again, this is thanks to the peperomia’s ability to root very easily.
  • To begin, take a leaf cutting. You can choose the kind of leaf you can do. If you want to propagate more than one new plant, take multiple leaf cuttings. Or you can divide each leaf lengthwise.
  • Once you have the leaf cutting, dip the edges in rooting hormone.
  • Then plant the leaf in well-draining potting mix. if you use leaf-halves, insert the edge of the leaf into the soil with part of it buried.
  • Keep the soil moist and cover the cuttings with a plastic bag to increase humdiity.
  • Then leave the cuttings in a warm spot with bright indirect light.
  • Just monitor the plant and don’t try to do too much except for keeping the soil moist and removing the plastic bag every so often to let fresh air in.
  • In about 4 to 8 weeks, you should see the leaves develop roots.

 

Peperomia Marble Stem Propagation

  • Stem propagation uses stem cuttings. Here, you’ll cut the stem instead of just the leaf. Ideally, you want to get a long enough stem to make it easy to bury it into the soil to submerge into water.
  • Try to pick healthy stems with at least 2 or more leaves on it.
  • Then, place the cutting in soil or water. You can choose between soil propagation or water propagation depending on what you like to do better or have better success with.
  • With water propagation, place the stem cutting into a glass container with water. Keep the stem submerged in water but remove any leaves that end up in the liquid.
  • With soil propagation, prepare a pot with well-draining potting mix. Then dip the cutting in rooting hormone and plant it into the potting soi.
  • Because you’re using a glass jar with water propagation, you can watch as the roots grow. This is not the case with soil propagation since the stem is buried in the soil.
  • Keep the new plant in a bright spot with no direct sun
  • After about 4 weeks, roots should be growing.
  • Once the roots get longer than 2 inches (in the water propagation), you can pot it up to soil.

 

How to Repot or Transplant Peperomia Marble

In most cases, your Peperomia Obtusifolia Marble will live in a 2 or 4 inch pot. As it grows, it will go up another pot size or so.

But don’t expect it to get big. In general, you’ll end up with a plant whose pot you can hold with one hand more or less.

That’s because its maximum size is limited to around 12 inches (give or take 2 inches). Also, it has a small root system.

Therefore, repotting is not common and it takes between 3 to 5 years before you need to do so. (The plant is a slow grower).

Another option to repotting you can go with if your plant is fairly bushy it to divide it.

This way, you maintain the size you want and not have to go up in pot sizes. Also, you get another plant out of it.

 

Is It Toxic/Poisonous to Humans, Cats & Dogs

No. The Peperomia Obtusifolia Marble is not toxic to people, cats or dogs. This makes it safe if you have pets or kids who like to explore and play around.

There is no risk of toxicity even if they ingest the plant’s leaves or stems.

 

Peperomia Marble Problems & Troubleshooting

Pests

I haven’t had any pest or disease issues with my Peperomia Marble. And it is generally resilient against them provided that it is healthy and is getting the proper requirements.

Thus, avoid stressing the plant as it becomes more prone to problems when weak.

That said, mealybugs, mites, scales and fungus gnats can appear and attack the plant. When you see this, treat them immediately.

You can use neem oil or insecticidal soap. I like to spray the bugs off with a gentle stream of water either from a hose or the sink.

 

Diseases

While there aren’t a lot of diseases that will hound the plant, it can still experience bacterial or fungal problems.

Pythium is one of the more common ones for peperomias. And it can lead to stem or root rot. Therefore, you want to watch for abnormal patches in the stems.

The best way to avoid disease is to stay away from waterlogged soil.
