After more than two decades of caring for plants, both indoors and out, I have learned that soil is the silent determinant of success. Light and water matter, but the soil determines whether those efforts produce strong, thriving plants or limp, failing ones.

Early in my gardening years, I assumed that any bag labeled “potting mix” was sufficient. The results proved otherwise. Roots rotted. Leaves yellowed. Hardy species became fragile. Through years of trial, error, and research, I developed soil blends that consistently deliver results. These mixes do not come from guesswork; they are tailored to mimic each plant’s natural environment.

What the Chart Provides

The Happy Houseplant Soil Recipe Chart distills this knowledge into a clear, practical guide. It provides the exact ratios of components for four common plant categories, explains what each ingredient does, and includes watering, light, and humidity keys for quick reference.

While the category of “Other Common Indoor Plants” covers many species, some have specific needs outside of the general guidance provided. This chart offers a dependable rule of thumb for beginners, giving them a strong starting point and allowing them to skip years of trial and error. As skills grow, adjustments can be made for more specialized plant care.

What the Chart Provides

  • Exact soil mix ratios for Pothos, Succulents, Monstera, and other common indoor plants

  • Watering, light, and humidity symbols for easy care reference

  • Explanations of core soil components and their roles in plant health

The correct soil composition prevents root rot, maintains steady moisture without waterlogging, and supports root aeration. By following these formulas, even beginner gardeners can avoid the common mistakes that lead to plant decline.


Tip: Always use containers with drainage holes to avoid stagnant water at the root zone.

The chart is available for download and will serve as a reliable reference for gardeners at any stage.
