Requirements and Care: 

General Instructions

ZZ plants are, on the whole, easy to take care of. They have problems when over-watered, or planted too deep, but other than that no major concerns. If the soil is kept too wet, the stems will rot at the point where the stem enters the soil. Our recommendation would be to not add any water to the ZZ until you are sure it needs it. One of the reasons ZZs are used extensively is that they require very little water. ZZs can also handle locations with light levels considered low to high. They are an excellent interior plant that requires little light and very little water.

Insects and Mites

In our experience with ZZ plants only scale and thrips have been observed as minor pests. Aphids and mites are not a concern on this plant, and thrips also should find the interior grown ZZ less desireable. Mealybugs, while not seen in the nursery could become a serious interior pest. Scale and mealybugs, usually found on the undersides of leaves and on the stems can be controlled with a systemic insecticide used as a drench. These insects will cause a black mildew to appear on leaves below the part the insect is inhabiting. The mildew grows on the secretions dropped from the insects. Look for this mildew to indicate a building population of mealybugs or scale.

Nutrition

An interior ZZ can be maintained for a very long time, (2 years or more), with little or no fertilizer. This will of course depend on the light that the plant receives. With very little light there will be very little growth and not much of a demand for nutrients. To be proactive, though, and to avoid nutrient related problems, add a dose of 20-10-20 or similar fertilizer to the irrigation water a couple of times per year. I would also recommend 2 Tablespoons of dolomite per year for a 3 gallon pot, and 4 tablespoons per year for a 7 gallon pot. The dolomite will add calcium and magnesium to the soil, but more importantly it buffers the ph of the media. Farm Life ZZs are grown using only a slow release fertilizer with dolomite additions.
