Let us look at the importance of choosing the best soil for growing a ZZ plant.
- If you do not follow the criteria of choosing the best soil for growing your ZZ plant, it can result in the plant to sit in unhealthy and soggy soil for too long.
- This is not a healthy state for the plant as it leads to oxygen deprivation and gives impetus for the fungal root rot to develop as well.
What Type of Soil Do ZZ Plants Need?
A ZZ plant is very particular in the type of soil that it prefers to grow and thrive. Here are some of the most important recommendations to keep in mind if you want to get the maximum out of your ZZ plant:
- Ensure that the soil is rich in nutrients. Some of the basic macronutrients required for the ZZ plant include nitrogen, potassium, and phosphorus.
- The soil mix should be well drained and porous enough for the excess water to drain off at any point of time.
- The soil should have proper aeration quality.
- If you find it difficult to deliver to this need of the soil, you can simply go and buy commercially available cactus soil to serve its needs of aeration.
Do not use a soggy or wet soil mix. If exposed to too much water for a longer duration, your ZZ plant can even die.

Start with store bough potting mix soil to grow ZZ plant.
Most potting mix has similar properties and this houseplant is capable of thriving in varied soil types.
However, if you want to make your own potting mix for different types of houseplants, then there are many ways.

Does ZZ Plant Like Acidic Soil?
The ZZ plant usually prefers a soil that has a pH level of 6 to 7. That is, it does not like to grow in extremely acidic soil, but thrives in slightly acidic soil.
Shifting the bar a little too low or a little too high might disrupt the balance of the soil, harming the plant.
Some signs that show that your soil is too acidic for the ZZ plant include frequent leaf burns, without the exposure to sunlight, and stunted growth of the plant, despite taking all the necessary measures.
Signs Your Potting Soil Mixture is Unhealthy
Are you doing everything right for your ZZ plant, including the right quality of soil, and seeing no results?
If the situation has been static for more than 2 weeks, then it is time to check your soil for possible signs of being unhealthy.
When we administer an unhealthy soil mixture to our ZZ plant, it can do more harm than any good. That being said, it is not an easy task to determine if the soil has gone bad.
There are a number of signs that you should look for before coming to a conclusion.
#1 Yellow leaves
If the green plants of your ZZ plant start to fall off, or become yellow and discolored, it means that your soil mixture essentially lacks a good quantity of nitrogen.
Nitrogen is a very important macronutrient for your ZZ plant. If you find that the ratio of nitrogen is comparatively lower than potassium and phosphorus, you can fix this issue by adding some organic compost.
#2 Foliage turning purple
If your ZZ plant leaves have started to turn purple that means your soil mix lacks phosphorus. As is true of nitrogen, the same is for phosphorus.
You can try spraying your plant with fertilizer that has a higher ratio of phosphorus than other two macronutrients.

#3 Excess nitrogen
If you are having trouble seeing a fruit or flower in your ZZ plant, then the villain might be the presence of too much nitrogen.
This happens when your leaves are green, but suffer from an absence of fruit. Try mulching to neutralize the level of nitrogen in your soil.
#3 Moss growing on potting soil
If your soil has grown moss, it certainly means that it has gone bad. The materials and composition of the soil mix does not matter as long as it has grown moss.
Under these circumstances, your ZZ plant will not get any benefit from your freshly created soil mix.
#4 Dry cracks on the growing soil
If your soil bed sees some cracks, then it means that your soil lacks moisture. As mentioned earlier, ZZ plants love to stay in a well-drained, but hydrating soil mix.
If your soil mix lacks water then it also lacks the ability to transport nutrients to different parts of your plant.
#5 Overwatered Soil
Too much moisture is also not good for your soil. A good way to look at it is that your ZZ plant roots have in fact turned into clubroots and your soil has become extremely wet and soggy.
It does not promote any growth of the plant and leads to root rot that leads the plant to die. However, if you follow our tip of having a well drained soil, then this obstacle should not trouble you.
#6 No soil aeration
Another reason is that your soil mix has turned into compacted soil. This happens when there is too much soil mix and too little space to grow it into.
If the soil particles are pressed too tightly, the pore space reduces and gives no space for the plant roots to breathe, thus preserving good plant growth.
