Let’s learn about each task one by one in detail.

Dieffenbachia Memoria Corsii Watering

Dieffenbachia Memoria Corsii prefers moist soil; however, it must be allowed to get dry between waterings. It should be watered regularly with lukewarm water. The watering schedule changes as the weather changes; you should set it by checking the soil dryness. In winters, the soil stays moist for an extended period; this plant requires less watering during winters. In summers, it gets dry quickly; thus, it should be watered more often.

As soon as you notice the 1-2 inches of topsoil start to get dry, shower this plant with water. You must water it thoroughly until excess water begins to drip from the drainage hole.

Soil Requirements

Dumb Cane Memoria Corsii does not fuss about soil type. All it asks is to never grow it in sand or orchid mix; all other potting mixes are acceptable. A well-draining potting mix with good organic content does pretty well for the proper growth of this Dieffenbachia species. You can use a mixture of perlite and potting soil for this plant. Potting soil retains moisture while perlite increases aeration. Both these ingredients prove great for the well-being of this plant.  Never let the soil pH increase than the normal value (7.0). Make sure you regulate the pH in an acidic range (6.1-6.5).

Dieffenbachia Memoria Corsii Sunlight

This plant can tolerate a wide range of sunlight exposures. It can survive in low light conditions and can also do well in partial shade or moderate sunlight. However, if you want to watch your Dieffenbachia Maculata Memoria Corsii thrive, grow it under the bright, indirect sun.

Low light will slow down its growth rate, while the direct sun will burn its leaves. This is why moderate sunlight is ideal for its proper growth. You should place its pot 6 feet away from a south-facing window or near an east-facing window.

Temperature Requirements

This pretty houseplant is a tropical species that grows best at average room temperature. The ideal temperature range for Dieffenbachia Memoria Corsii is 18-23ºC. It is not hard to maintain inside a home. On the other hand, if you are growing this plant outdoors, you should take special care of it in extreme summers or extreme winters. It is not cold-hardy, nor can it tolerate high heat.

You should move this plant indoors when the temperature drops below 12ºC. You can also grow this plant in a greenhouse in winter to maintain its ideal temperature.


The greyish-green glossy leaves of this tropical evergreen need high humidity to stay fresh and vibrant. Low humidity can lead to discoloration and droopy leaves. You should regulate the humidity around 60% to provide an ideal surrounding to this plant. The best way to do this is by placing its pot above a pebble water tray.


Dieffenbachia Memoria Corsii care includes feeding it every six weeks to two months. It should be fertilized with a liquid houseplant fertilizer that contains a balanced amount of essential nutrients and micronutrients. You should water the plant before fertilizing it, and you should also dilute the fertilizer first.

Grooming and Pruning

If you love a fuller appearance of the plant, you should prune it more often. Cutting the leggy branches encourages healthy growth and more branching. You should trim all the crisp leaves and brown tips. The best time for grooming and pruning is the months of active growth.

How to Propagate Dieffenbachia Memoria Corsii?

Dieffenbachia Memoria Corsii is one of the easiest species to propagate. You can propagate this plant through stem cuttings or growth cuttings. Its propagation process involves just the basic steps that are simple enough to carry out. If you have no idea how to increase your Dieffenbachia collection, let us guide you.

  3. Go for young stems; they grow actively.
  4. Place the stem cutting in the rooting hormone for some seconds to increase its growth rate.
  5. Place the cutting in moist soil.
  6. Keep watering the soil until new roots grow out of the stem.
  7. This will take 3-4 months.
  8. Once the stem has new roots and new buds, move the stem cutting to a proper pot.
  9. You should place this baby Dieffenbachia in a well-lit spot.

Frequently Asked Questions about Dieffenbachia Memoria Corsii

Why Do the Leaves of My Plant Have Dark Spots on Them?

The plant gets nutrients from the soil. After each year, all the nutrients get used up and need to be replenished. Dark spots on leaves or yellow leaves indicate that your plant needs repotting and fresh soil.

Can I Propagate My Dumb Cane Memoria Corsii in Water?

Water propagation is not effective for this plant. The stem cuttings do not produce new roots if they are placed in water. You should either use the air layering method or plant the cuttings in potting soil.

How Can I Revive My Dieffenbachia Memoria Corsii?

If exposed to an extended drought, this plant can enter dormancy irrespective of the time of the year. For bringing the plant back to life, you should regulate its watering schedule, place it in a well-lit spot, increase the humidity, and mist it now and then. All these tricks will revive your plant, and it will start growing again.

Why Are There Brown Spots on the Leaves of My Plant?

Over-fertilization is the main reason. In winters, when the plant is in dormancy, it does not need to be fed. If you keep adding fertilizer to its roots, its leaves will develop brown spots, salt will build upon its soil, and the plant will eventually die. This is why it is recommended to avoid fertilization in winters.
