Zamioculcas plant care, watering and varieties

Zamioculcas
0

Ranks of deep green evergreen leaflets rise on upright stems, and in a well-lit spot a new shoot can lengthen a whole inch in three days. The ZZ plant (Zamioculcas zamiifolia) stores water in those stems, so it shrugs off months of neglect — the one thing it will not forgive is direct sun.

Care easy

Repotting, watering and proper exposure are easy care tasks. Each will make your Zamioculcas even more beautiful!

Planting and re-potting Zamioculcas

Upon purchasing, if the pot is too small, repot your zamioculcas. This helps the plant grow more adequately.

Usually, plants are sold just before repotting is needed, so don’t delay. After that, every 2 or 3 years, repot your zamioculcas plant.

Repotting zamioculcas
Repot in spring, every two or three years

Spring is the best season for repotting. Use a pot of a slightly larger size (1 inch/2-3 cm).

  • Zamioculcas roots hate excess water. Ensure that the pot has proper holes at the bottom. Also, increase drainage with a layer of gravel or clay pebbles along the bottom of the pot. Extra water will flow out more easily.
  • Good soil mix is needed. Since it lives indoors, soil mix is the only source for all nutrients the Zamioculcas needs.
  • Splitting a large Zamioculcas will rejuvenate both halves.

Best exposure for zamioculcas

The best place to set your zamioculcas up is near a window. It should let a decent amount of light through, but not direct sunlight.

Zamioculcas have been noted to survive with very little light.

Exposure for Zamioculcas
Plenty of light near a window, never direct sun
  • Indeed, Zamioculcas is vulnerable to excess sun, and tolerates part shade when outdoors.
  • Avoid setting your zamioculcas near heat sources such as radiators. These tend to dry the air and leaves. Moisture is what this tropical plant needs most.
  • Although it will survive in low light, it grows faster the more light it gets.
  • If lacking light, the plant will try to produce very long stems to search for light. Low light won’t kill your Zamioculcas, but will slow its growth.

When well-exposed and watered, a new Zamioculcas shoot can grow up to an inch in three days (1 cm/day)!

Zamioculcas care through the seasons

The same plant needs two very different regimes across the year: a moist, well-fed growing phase and a dry, dormant rest. Use this table to work out which one your plant is in.

Zamioculcas care through the seasons
Season Watering Feeding Main task
Early spring Resume watering as new sprouts appear Start liquid feeds again Repot into a pot about 1 inch (2-3 cm) larger, every 2 or 3 years
Mid-spring to late summer Keep the soil mix moist, checking that water drains away Leaf plant liquid fertilizer every 8 to 15 days Mist or spray the leaves with calcium-free water
Early autumn to late winter Wait for the soil to be dry before watering again Stop adding fertilizer Let the plant take a dry, dormant rest; leaves may fall

Whatever the season, let cold tap water stand near the pot for an hour so it warms up and loses its chlorine.

Watering zamioculcas

Regular but moderate watering will help your zamioculcas thrive.

Drooping, falling fronds mean the plant is too dry

If you don’t water enough, fronds fall over and leaves start drooping.

  • Soft water is preferable by far, especially rainwater.
  • When using tap water, let it sit for an hour for chlorine to evaporate.
  • Ideally, set the water near the pot during this time for the temperature to match nearby room temp.

How often should you water zamioculcas? It depends on the season:

Watering in spring and summer

Mist spray zamioculcas
Mist the leaves with calcium-free water in summer

Keep the soil mix moist and check that water drains properly.

Add leaf plant liquid fertilizer every 8 to 15 days during the growing phase.

  • Mist or spray leaves on a regular basis with calcium-free water.
  • Clean the plant with a rag dipped in rainwater if dirty.
  • Shower the plant with soft water to remove dust.

Fall and winter watering

Reduce watering and wait for soil to be dry before watering again. Your Zamioculcas will benefit from having a dry, dormant season every year during winter.

Growth slows, and in some cases leaves fall off entirely, much like deciduous trees outdoors. Don’t worry: new sprouts appear in spring.

  • Stop adding fertilizer.
  • Water is usually colder in winter. Let the cold water sit near your plant for at least an hour. It will warm up and won’t cause cold shock.

Propagating Zamioculcas zamiifolia

It’s easy to multiply zamioculcas, but it takes months. An effective technique is that of leaf cuttings.

Zamioculcas propagation
Leaves pricked into sand form new underground shoots
  • Cut a healthy stem off from the Z. zamiifolia plant.
  • Detach each leaf from the stem, pulling it gently
  • Prick the leaves halfway in soil or river sand, water.
  • Keep moist but not soggy.

After about 2 to 4 months, leaves wilt away. From underground, new shoots appear. Transplant to individual pots at this stage.

Instead of preparing cuttings, another option is to simply split the root bunch. This is called dividing the plant.

Diseases and pests found on zamioculcas

If your Zamioculcas stems and leaves turn yellow, it is most certainly due to excess watering. Overwatering also results in leaves losing their firmness and become soft.

If you haven’t watered the plant in a very long time, it might trigger a baffling reaction. Indeed, it may be that your Zamioculcas loses its leaves.

This might happen after forgetting to water for over a month. Simply resume watering, a bit more regularly this time. New growth will sprout.

  • Tip: if your plant has recently shed its leaves, collect them for cuttings instead of tossing them away.

One last point regarding parasites: Zamioculcas is vulnerable to scale insects.

Types and varieties of Zamioculcas

Zamioculcas is a recent commercial plant. In 30+ years, not many prized mutations have appeared.

An exciting development appeared in 2017: a black Zamioculcas. It is sold under the name Raven ZZ plant.

  • As of today, there are many more new Zamioculcas varieties, you’re sure to find the one to suit your home!

Variegated ZZ plants grow more slowly and their cream patches scorch easily, so keep them out of direct sun.

Learn more about zamioculcas

Zamioculcas got its “ZZ plant” nickname from its botanical name: “Zamioculcas zamiifolia”. It originated in southern Africa in the Zanzibar region. This explains why one of its common names is also “Zanzibar gem“.

  • The deep green of the lush, original variety led the plant to also being called “Emerald palm“, which suits it well!

One of the previous names was Caladium zamiifolium, possibly because of the resemblance of its roots to those of the Caladium family. However, that name has since been replaced.

Is Zamioculcas zamiifolia poisonous?

Zamioculcas contains microscopic calcium oxalate crystals. These crystals are irritating compounds in sap, leaves and roots. Calcium oxalate causes rashes. Although this may be uncomfortable, there’s no need to panic if your child or pet have ingested small amounts.

Zamioculcas isn’t toxic, poisonous or life-endangering in small quantities. The irritation may cause light swelling and pain.

Smart tip about Zamioculcas

Zamioculcas is considered a “succulent”. In the wild, stems store water during floods. It can survive for months without watering. Zamioculcas is an appealing houseplant for forgetful people!
