Potting Mix Ratio Calculator
Calculate the exact volumes of perlite, compost, and soil for a fast-draining Bougainvillea mix.
Quick Answer
The ideal Bougainvillea potting mix is highly aerated and fast-draining. We recommend a mix of 55% high-quality potting soil, 20% perlite or pumice, 10% orchid bark, and 15% compost or worm castings. Avoid heavy peat-based mixes that stay soggy, as Bougainvilleas are extremely prone to root rot.

These baseline ratios and decision rules are included directly in the page so visitors can review core guidance before using the interactive calculator.
| Scenario | Baseline Rule | Safety Note |
|---|---|---|
| Standard mix | 55% potting soil, 20% aeration, 10% bark, 15% compost. | Balanced for ordinary Bougainvillea. |
| Aroid mix | 30% potting soil, 30% aeration, 30% bark, 10% compost. | Chunky structure supports airflow around roots. |
| Succulent mix | 25% potting soil, 50% aeration, 15% bark, 10% compost. | Fast drainage reduces rot risk. |
Formula summary: Potting mix outputs are volume splits from plant-specific ratios, adjusted for drainage preference and normalized to the requested total volume.
The Problem
Many plant owners guess at their care routines, leading to root rot, burned leaves, or stunted growth. Generic advice doesn't factor in specific plant species and local climate.
When to Use This Tool
Use this calculator when you bring home a new plant, when seasons change, or if your plant is showing signs of distress.
Who is this for?
- Beginner Bougainvillea owners looking to avoid common mistakes
- Advanced collectors wanting to optimize growth rates
Drainage is the secret to keeping potted Bougainvillea alive.
The "No Wet Feet" Rule
Bougainvilleas despise sitting in water. Their fine, fragile root systems will rot in a matter of days if the soil remains soggy. A standard bag of indoor potting soil retains too much moisture. Amend it heavily with perlite or coarse pumice to ensure water drains quickly through the pot.

Troubleshooting Guide
1 Mix stays soggy for more than 5 days
Cause: Poor drainage holes, too much base soil, or using a very fine, peat-heavy base.
Repot using an "Extra drainage" setting (adding more perlite and bark), and ensure the pot has large, unobstructed drainage holes.
Glossary of Terms
- Perlite
- A lightweight volcanic glass used to improve soil aeration and drainage.
- Orchid Bark
- Coarse chunks of bark that create large air pockets in the soil, preventing compaction.
