Foliage-Pro 9-3-6 Review for Houseplants: Is It a Good All-Purpose Fertilizer?
Quick answer: Foliage-Pro 9-3-6 is a strong general fertilizer option for leafy houseplants because its 9-3-6 analysis follows a 3-1-2 nitrogen-phosphorus-potassium ratio and the published formulation also includes calcium, magnesium, and trace elements. That makes it appealing to people who want one concentrated foliage feed rather than several separate bottles.

Who it is best for
- Pothos
- Monstera
- Philodendron
- Ficus
- Other actively growing foliage houseplants
Why we like the formulation
The 9-3-6 ratio places more emphasis on nitrogen, which supports leafy vegetative growth. The published formulation also lists calcium and magnesium, nutrients often discussed separately in plant-feeding programs.
What it will not do
Fertilizer cannot compensate for low light, root rot, poor drainage, or a plant that is dormant or severely stressed.
How to use it safely
Start with the label directions and err on the conservative side for indoor plants. Concentrated fertilizer is easy to overapply. Never assume that twice as much fertilizer means twice as much growth.
Signs you may be overfeeding
- White crust on soil or pot edges
- Brown leaf tips after feeding
- Root stress in an otherwise wet pot
- Very soft weak growth from excessive feeding combined with low light
FAQ
Is Foliage-Pro only for hydroponics?
No. It is also widely used for container foliage plants when diluted according to directions.
Should you fertilize every watering?
Only follow a feeding method supported by the current product label and your plant's growth conditions. Indoor plants often need less during slow-growth periods.
