Ultimate Guide For Planting the Codiaeum Mammy


The Croton Mammy, a perennial plant, thrives in a warm humid environment with temperatures ranging from 60-80℉.

Being a native of tropical climates, the Mammy Croton survives outdoors only if the temperatures do not drop below 50-60℉.

Exposure to extremely cold temperatures causes leaf loss. For colder climates, the Codiaeum Mammy is grown in greenhouses and indoors.


For a plant popularised by its multicolored leaves, the Codiaeum Mammy loves good lighting. However, this should not be mistaken for the need for it to be overexposed to the sun.

Mammy Croton leaves need bright but indirect light for them to properly show off their hues of color. Little or no light will turn the leaves green and dull while on the other end striking a good balance for the light exposure gives it an extremely different outcome.

For it to survive in a hot and dry environment, with exposure to harsh sun, the Croton Mammy can be cushioned against such extremes by placing it under a shade.

Soil & Fertilizer

Crotons can survive all types of soil but require a well-drained soil type. Codiaeum Mammy thrives in well-draining soils with the soil pH level ideally between 4.5-6.5 pH. Ph levels higher than this are highly discouraged, for instance in rock-soils, because they contain high levels of calcium. Ensure that your Mammy Croton grows with all the necessary nutrients by applying a quality granular fertilizer three times a year, in the soil at least once in spring, summer, and fall.

How To Propagate Your Mammy Variety

The most common way to propagate your Croton Mammy is by cutting the stem and replanting it, but that’s not to mean you can’t try other methods such as propagation in water, or air layering.

Propagation by Stem Cuttings

The most standard way to grow the Codiaeum Mammy is from its stem cuttings. How do you do this?

  1. Cut a segment from a healthy stem with a minimum of three sets of leaves noting to remove the bottom leaves and maintaining an average of three to five leaves at the top.
  2. Place the cutting in a glass of water and set it in a warm, bright setting. Ensure that you change the water every couple of days for the best results. Within a couple of weeks, you should have roots cropping beneath the soil.
  3. Dip the end of the Croton Mammy cutting in a glass containing water or root hormone, and plant it in a soilless medium for instance coco coir or peat moss, sand, and vermiculite.
  4. Ensure that you cover your planted cutting with a humidity trapping cover, such as a plastic bag or a disposable plastic can, the roots should develop within a couple of weeks.

Similarly, you can place the properly trimmed Croton Mammy stems in a slightly perforated plastic can, with moist soil, and then cover it with a humidity trapping cover. After a few weeks, the roots will develop, which makes it more convenient for plant repotting.

Air layering

Besides propagation by cuttings, you can use air layering to propagate the Codiaeum Mammy.

  1. Make a diagonal cut through one third to half of the diameter of a stem while it’s still attached to the main plant.
  2. Treat the resulting wound with some rooting hormone, and keep it open with a wooden matchstick or toothpick.
  3. Carefully place damp moss around the area, and wrap it in plastic wrap.
  4. Ensure to keep it moist – if the moss begins to turn tan in color, that is a sign for it to be remoistened. Over time, the wounded part will begin to form roots, once properly developed, unwrap the plastic wrap and trim the rest of it through the stem, and repot your new plant.

Propagation by Roots

One might wonder what to do with the old and mature Croton Mammy shrubs. This can be used to propagate new plants, by simply separating the Codiaeum variegatum at the root, and replanting a cutting, especially if the plant has outgrown its prior container.

This can be challenging because the Mammy Croton does not like to be moved around, as such both your original plant and the new cutting may suffer wilting and or leaf-loss.

Whichever method you use to propagate the Codiaeum Mammy cutting, the once the roots develop, repot the new plant into an appropriate, well-draining pot and position it strategically, to maximize on the light, humidity, and temperature for healthy growth.

Repotting Codiaeum Mammy

You have successfully propagated the Croton Mammy plant or even bought a grown one from a vendor, and would now like to place it in your preferred pot. So here’s the quick guide:

  1. Select a pot that is 1-3 inches bigger than the original pot so that your plant grows adequately and with no near need for repotting.
  2. Remember the Mammy Croton is sensitive to movement and as such, limit your need to re-pot it to once every 2 to 3 years and preferably, during spring. Your preferred pot or container should have a proper drainage hole(s) or in the event, it does not drill holes for drainage at the bottom.
  3. Put some soil at the bottom of the pot and let it settle. Then gently remove your Croton Mammy from its old pot or pack. If they are in a pack, gently separate the individual plants, by holding it at the base and carefully massaging the roots to detangle them. If the roots are completely entangled, you may have to use a potting knife gently to detangle.
  4. Make sure that there is enough soil at the bottom of the new pot before planting, it should be slightly over an inch of the pot’s top.
  5. Then, make a small hole in the soil slightly bigger than the root of the Mammy Croton and once settled in, cover the top with more soil.
  6. Thereafter, adequately water the newly potted Croton Mammy, so that the soil completely settles in.

Pruning Your Codiaeum Mammy Plant

Being a potted plant, the Codiaeum Mammy will require pruning from time to time for the general aesthetic and natural beauty.

You may also need to resize it if the growing pot is medium-sized a get nd rid of the dead leaves. Pruning will help tame the length of the roots because the plant is centrally placed in a pot and will equally encourage budding of new nodes and leaves.

Prune the dead leaves and branches to the main body of the plant. On the other hand, diseased branches ought to be cut off at least six inches outside of the sick or wounded part. While overgrown branches should also be cut back just above a leaf or node on the stem to maintain the plant’s shape.

Avoid cutting more than a third of a branch’s length off at any given time unless the part is dead or diseased, so you don’t stress the plant which allows it to form a new leaf growth before pruning it again.

How to take care of Codiaeum Mammy

Other than regularly ensuring that the Croton Mammy grows within its optimum soil, light, temperature, and water conditions and pruning, it cannot be classified as a high maintenance plant. Ensure to look out for and understand the following worrisome signs and how to remedy them accordingly;

Leaf Loss and Leaf Drop: As stated earlier Mammy Crotons are very sensitive to excess water and movement. Should you choose to have one as an indoor plant, strategically choose a spot for your pot that will not require excess movement, otherwise, your plant will experience leaf drop. Similarly, too much water will cause the leaves to wilt.
