ZZ plant: Diseases and Remedies (Zamioculcas zamiifolia)

NOTE: The terms ZZ plant and Zamioculcas zamiifolia are identical in this text; in reality, Zamioculcas zamiifolia is ZZ plant’s biological word.

ZZ plants, also known as Zanzibar gems, are low maintenance and are characterized by their shiny, wide, oval-shaped leaves that shoot upward. Sometimes these plants are mistaken for artificial plants, because of their deep green leaves.

They are slow growing, so you won’t need to repot often, but if you do plant or repot a zz, you should do so in the spring or summer when it’s in an active growth phase. There are plants that are mildly toxic to humans and animals.

Why are my ZZ plant leaves turning yellow?

Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.

Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:

Each deficiency produces a different yellowing on the Zamioculcas zamiifolia in question, here’s how to spot them:

  • Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
  • Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
  • Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
  • Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
  • Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.

Our Solution

According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.

Is my ZZ plant sunburned?

It is simple to determine whether your ZZ plant (your Zamioculcas zamiifolia) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

As we saw above, if your ZZ plant receives too much water or not enough light, the leaves may also change color.

To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.

Why are my ZZ plant leaves turning brown?

The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.

Should I leave my Zamioculcas zamiifolia in direct sunlight?

No! If your Zamioculcas zamiifolia (or ZZ plant) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your ZZ plant is in such a state!

Our Solution

The remedy, as said in the paragraph above, is simple: just move your plant’s ZZ plant out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.

Why are my Zamioculcas zamiifolia leaves drooping or wilting ?

In most cases, this happens when your Zamioculcas zamiifolia lacks water. This is especially the case for large plants, naturally they need more water than others.

Drooping

An easy way to know if your Zamioculcas zamiifolia is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!

Our Solution

If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the ZZ plant right after a dry period thinking that it needs a lot of water.

This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.

Caring Tips for Zamioculcas zamiifolia

Water Occasionally

Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Zamioculcas zamiifolia.

You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.

Always keep temperatures stable

Maintaining a consistent temperature for your Zamioculcas zamiifolia is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Zamioculcas zamiifolia close to air conditioners, radiators, or other sources of hot or cold air.

Keep your ZZ plant Dust-Free

This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.

For your ZZ plant, this would be a true descent into hell, and it would also appease the pests.

Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!

Keep drainage in mind

If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.

If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
