ZZ plants, Zamioculcas zamiifolia, are beautiful, unique, almost impossible to kill Succulent Plants that burst onto the market several years ago. They have become an immediate hit.
Indoors, ZZ plants can survive in low to bright indirect light. Since a ZZ plant is a slow grower even in good light, in low light these plants rarely produces new leaves. Direct sun fades and burns the leaves.
Over-watering is the main way to kill a ZZ plant. They do not like wet feet so allow the soil to thoroughly dry out before watering. ZZ plants have thick roots called rhizomes that store water so when in doubt, do not water. Unlike most plants, Zamioculcas are very forgiving plants, allowing you to over-water a few times before showing signs of serious damage. Yellow leaves are an indication that the plant has been over-watered or severely under-watered. water meters are not always reliable. If there is a lot of salt in the soil from too much plant food or if you are using water that has passed through a water softener (too salty) then a water meter is unreliable. In very warm weather, a ZZ plant may need water every 7-10 days. In cooler weather, the plant may be able to go 2-3 weeks before needing water. When you do water, water well enough so that the water comes out the drip holes in the bottom of the pot. Do not allow the plant to sit in the excess water in the saucer for more than 10 minutes.
A Zamioculcas zamiifolia plant prefers temperatures between 60°-80°F (15.6°-26.7°C). Temperatures below 60°F (16.6°C) slow down the plant’s growth. ZZ plants do well in basic household humidity.
These plants are very pest resistant. ZZ plants are also resistant to most plant plant diseases, but quite susceptible to root-rot caused by over watering.
ZZ plants can be found in 4”-14” pots. These are very expensive plants, especially mature specimens, because they are such slow growers.
