The selections of leaves and stems should be perennially curious. You will find Zanzibar Gem (ZZ) in any plant-candy store. 

We want to talk a bit about the ZZ plant! Instagram is all about houseplant collection. Do you know Z. zamiifolia is known as a social media darling? Zamioculcas zamiifolia (ZZ) is a famous plant for centuries. It is mainly origins in Africa. I have discovered this plant in Africa’s Dutch nurseries. The plant has been getting distributed since 1996 around the world. People love growing this plant in homes and offices.

A ZZ plant; things to know

ZZ plant has dark green leaves. It looks attractive with its broad favorable traits, especially for offices and homes. These are famous for being drought tolerant. You can keep the plant in low-light conditions, and it won’t mind! The beautiful part of these ZZ plants is their smooth leaves. They reflect sunlight and brighten your room slowly to a height! Don’t be a fool considering the ZZ plant as a monster plant even though it proliferates. We have a shocking update! NASA’S study says that the ZZ plant works like an air purifier. The plants remove a copious amount of toxins from the air. Xylene, toluene, and benzene are such toxins that live in airflow.

Are ZZ plants poisonous? Can they be propagating?

Well, for the first time, I heard that all parts of the ZZ plant are poisonous. I was in Africa then, talking about the 2010s. However, people added some false blame on the plant like it causes cancer and needs to wear gloves to touch it! I don’t give sight to these rumors. I admit that the plant is toxic, but it does not spread cancer or is not cancerous. If you have pets or curious children at home, please keep the plant away from them. If eaten, an animal can die. Wearing gloves to maintain the ZZ plants is a good practice. These plants can cause skin irritation. Please wash your hands properly after handling them. I know you’re much aware of this pandemic COVID-19’S time. 

The behind story of the ZZ plants being toxic is their origins from large and thick rhizomes. The rhizomes store water and resemble potatoes. Their growth is praiseworthy during the droughts! Propagating ZZ is as easy as the replanting process. You have to separate the rhizomes and plant them to grow together. Besides, a cutting with a bit of stem will help the propagating thoroughly.   

Do ZZ plants need Fertilizer?

It is an excellent plan to feed the ZZ plants with worm compost and compost fertilizer. These plants are not fussy even if overfertilized though you should keep your plants from excess fertilization. However, our recommendation is to fertilize the ZZ plants once a year between February and early March. Be mindful of the fertilization process once if the plant’s soil required being fertile! At length, you should consider using Fertilizer as ZZ plant care tips! 

Besides Fertilizer, it is essential to be concerned with Exposure, Watering, Temperature, Humidity, Soil, Propagation, and pests’ safety. We must write a detailed guide on this. Read us below.   

  • Light exposure

Light exposure is one of the significant factors to keep your ZZ plants safe! Our recommendation is to have moderate or medium-light for this plant. It is the key to a good appearance. I have seen people describing it as a low light plant. I agree. They tolerate it. If kept in Low light, the ZZ plant will be very leggy by roots. Never mistaken keeping these plants in the hot sun, especially do not keep ZZ plants against a hot window. The leaves will burn in direct sun. A room with moderate light exposure will be a wise idea. Be mindful of keeping the plant at least 10′ from the temperature.

  • Watering your plants by the temperature 

Here comes the most important thing for the plants ‘Watering.’ The ZZ plants grow from tuberous rhizomes. The rhizomes store water in them and are structured with spongy stems. It is a good idea to keep your plants from overwatering. Don’t water these plants for 2-3 weeks. I do watering every 3-4 weeks in winter. You should adjust accordingly to your city’s weather. Knowing the local temperature is a brilliant skill. Once you understand the best weather for your houseplants, you’ll be sure to make them grow comfortably. If you’re keeping these plants away from windows, keep them in a secured room or on a balcony. It would be best to use air conditioning or any kinds of heating vents for ZZ plants. Overheating can affect your ZZ plant leaf with sunburn. 

  • Humidity

Zamioculcas zamiifolia plants grow well in tropical regions. Fortunately, these plants are adaptable in homes. ZZ plants can consume dry air. If the plants are kept in hot, dry Tucson, ZZ leaves turn brown with a few tiny tips. Sometimes, your plants look stressed. It is because of the lack of humidity. Why not fill the saucer with pebbles and water in case? It would help if you made drain holes at the bottom of the pot. Misting will be helpful a few times a week! You can try.

  • Soil mixture 

Soil should be mixed into three parts of the earth. I keep my potting soil with the succulent, cactus mix, and coco coir. The mixture should be a handful. Be concerned about adding these ingredients depending on the size pot. It would be more powerful to enrich the top with a 1/4- 1/2″ layer of worm compost. You can purchase all the ingredients like compost, succulent, and coco air from a nearby company. Let’s discuss a bit about the potting soil & worm compost I use. We want to add a detailed product review on the soil ingredients below. Hopefully, you stay till the end!
