I just bought a ZZ plant from Home Depot and I just love the look of it, but I had a couple of questions that I am having a hard time finding answers to on the internet. As you can see in the first photo, they cut some of the stalks (?) off leaving these abrupt stumps. Is there a way to make them grow again? Also, there are some dark black areas running up the outer edge of a couple of the stalks. They weren't there when I bought them. Could this be shock? I've only had it since Sunday, so I am hoping it will go away as it adjusts to my office.
It appears that they just cut away parts of the plant that were likely dead or near dead.
Many times plants that are sold in these type of garden departments are all loaded on the same rack together, and are watered on a schedule, not necessarily if the plant actually needed watering.
ZZ plants need only to be watered after the soil has dried out.
The cut parts of the plant will not regrow. An open wound on a plant can be susceptible to disease or even insects.
You can treat the plant with Neem Oil.

What is happening to my plant? I received this plant as a gift a month ago and have not watered it because I'm afraid to overwater it. But the leaves are still turning yellow and brown.
If the soil has dried out, it is time to water your plant again.
Give it a nice drink and allow the excess water to drain away.
Also if the plant is getting to much light, it may respond with yellowing leaves. Adjust the conditions to filtered light.

I bought a zz plant three weeks ago and had to repot it because it was in a really small pot. I put some peat moss in a larger pot and put the plant in, then added some peat moss. Finally, I watered it, but only that time. Then, gradually, the leaves turned yellow. I noticed that the stems have rotted and there are some mold lines on it. The plant died, unfortunately, and I had to throw it a way. By the way, one stem remained green, which was broken, while the other turned yellow earlier. I really like zz plants and want to get another one but I need some help to keep it safe and growing.
Your plant was likely placed into a pot to large for it's root system.
This led to overwatering and to much water for the rhizome.
A ZZ plant can go months without water.

I received one, and it has no roots. How do I plant it and in what?
You have a 'cutting' from a plant that yes, can be rooted.
You can cut the leaf stem to about 3 or 4 inches and give the stem a fresh cut at a slant.
Place it in a glass of fresh water and locate it in a bright location but away from direct sunlight.
Top off the water when it gets low so that the new roots do not come out of the water.
You can also place the cutting in a small 3" pot of potting mix.
Dip the end of the stem in rooting hormone and place the stem in the soil and tamp it down.
Bright location and keep the soil moist.
Though ZZ plants are easy to grow they are very slow to propagate.

Can I keep it outside in a covered area in Baton Rouge, Louisiana? It is too big to move indoors. We have some hibiscus and other tropicals that we keep outside. Sometimes move up towards the house and cover if there is going to be a hard freeze. I bring in Christmas cactus and Ixora, but the ZZ plant takes up a lot of space.
A ZZ plant will freeze and die if exposed to freezing temperatures.
The plant will do best in temperatures 60 to 75 degrees F.

How do I go about thinning this plant. I bought it in a medium pot transplanted it to a bigger pot, which it outgrew, then I took it to a nursery who transplanted it again in a huge pot but it is now starting to outgrow this pot and I do not want it to get any bigger. I have trimmed some branches that when broken when we recently moved but it keeps getting new shoots and I don't know how to trim it. Thank you, Pat @ patragz@comcast.net
ZZ plants are generally slow growing. Don't fertilize the plant.
Keep it more root bound to also slow it's growth.
You can trim the branches if they are too tall.
