ZZ plant Zamioculcas Leaves turning yellow. I started my ZZ plant about 4 years ago from a clipping. I water it about once a month.
I've never had a problem with it until now. The leaves on one stems have all turned yellow. This is first stem that grew 4 years ago. I've attached photos so you can see what I mean. I love my ZZ and any help I can get will be appreciated. By the way, should I cut this stem off? If so, is there a proper way to cut it? Thank you. If many of the leaves on your ZZ plant are yellowing and you see the stalks drooping, carefully pull out the plant from the pot and inspect the roots.
Root rot should be easy to spot as the roots will be mushy, darker, and will likely have a foul smell. Remove the damaged roots, remove soil around the affected area. If only a small area is affected, you can leave the soil around healthy roots. If too much of the root system is affected, remove the soil, clean the roots and plant your ZZ plant into fresh soil. You will also need to repot the plant into fresh soil if there is a sign of root rot and the soil is still soaking wet.
Many care guides state that ZZ plants thrive on neglect. However, this can easily be misunderstood. It needs regular watering to be happy, just less than many other houseplants. When you are checking for root rot, there might not be any present. The roots might have gotten too big for the pot, and now your plant is root-bound. You might even see roots growing above the soil which is a sure sign you should check what is going on under.
If there is no more room for the roots to grow, you will need to repot your plant into a bigger pot. Repotting, while necessary, is stressful for plants. Even if your plant was completely healthy before repotting, it could struggle after you have repotted it. Some leaf yellowing can be normal, as well as plants looking poorly for a while.
Keep it in an area with bright, indirect sun so that it can dry quickly, and reduce your watering frequency. You may have to move your plant closer to the window for a quicker drying time. To prevent over watering, always check that the top layer of soil is dry before watering by sticking your finger in, or using a moisture meter. Remember : if your ZZ plant is in a cooler or darker area, it will require less watering than if it were somewhere warmer or brighter. Since ZZ plants do not need to be watered often, it is very easy to forget to water them for a long time.
While ZZ plants prefer to be on the drier side, too little water will lead to ZZ plant leaves yellowing, shriveling up, or dropping off easily. On the bright side, under watering is easy to fix and your ZZ plant should bounce back after a quick drink.
Water your ZZ plant enough to wet the soil without drenching it. While it is tempting to over water when you know your plant is dry, do not completely soak the soil. If there is any excess water left in the saucer, dump it out so the plant does not sit in water. If your ZZ plant is somewhere hotter or in brighter sun, it will need slightly more frequent watering.
As you can see, watering ZZ plants properly is crucial to their health. How often you need to water depends on many environmental factors, such as temperature, sunlight, humidity, pot size, soil type, and ventilation. Start off by watering ZZ plants once every 2 weeks in the summer and once every 3 weeks in the winter.
Always check that the top few inches of soil are dry before watering to get an idea if your plant needs moisture. You can adjust the schedule depending on the specific conditions your plant is in. When you water, soak the plant when the soil is completely dry, and empty out the saucer so the plant does not sit in water. Let the soil completely dry out before you water again. ZZ plants like to be infrequently soaked : do not mist the plant or let the leaves stay wet because that can cause rot.
Furthermore, plant your ZZ plant in a well-draining soil and in a pot with a drainage hole. This will help the soil dry quicker, preventing rhizome rot. Fertilizing too often or not enough can cause nutrient imbalances, resulting in yellow leaves.
This is a less common cause of your ZZ plant turning yellow. Fertilize ZZ plants once a month with a dilute, water soluble fertilizer during their growing season April to August. To prevent fertilizer burn, do not fertilize more often than once a month, fertilize during the winter, or use a strong fertilizer.
If you suspect you have over fertilized, flush out the soil with a lot of water to remove the excess salts or repot the plant in fresh soil. Since ZZ plants are tolerant of nutrient poor soil, if you have fertilized your plant at least twice in the past year, nutrient deficiency is unlikely. If you have not fertilized your plant at all, try it once and see if the color improves.
ZZ plants thrive in medium light , and are even tolerant of low light conditions, making them a great addition to any dark corners.
