If the ZZ plant doesn’t scare you away and you decide to get one, here are some tips to help you along the way.

As mentioned before, the ZZ plant is very low maintenance. It needs well-draining soil because it doesn’t require as much water as other plants.

You can fertilize it once every month during watering. Be sure to water when the soil is completely dried out.

The plant thrives in low-light environments, but it loves places that have indirect light.

If it likes the home you’ve given it, it may flower in the middle of summer and early fall – however, the plant is primarily a foliage-based plant.

To propagate the ZZ plant, we suggest that you wear gloves to protect your skin, but it is very easy to do. The plant grows from their large and thick rhizomes resembling potatoes.

These rhizomes store water, which is why they don’t need constant watering.

The way you propagate the ZZ plant is to separate the rhizomes and replant them.

Conclusion

It is also a great plant for an office or for someone who perhaps doesn’t have a green thumb.

The toxicity of the plant shouldn’t scare you away unless you are worried about your pets or children.

However, they can be protected if you take the precautions, and no significant harm will come from contact.

Good luck with your ZZ plant if you have decided to take on the toxicity!
