Repotting Calculator
Calculate exact pot size upgrades while learning how to protect their fragile roots.
Quick Answer
WARNING: Bougainvilleas despise root disturbance. Their roots are fine and easily torn, which can shock or kill the plant. Only repot when the plant is extremely root-bound. When you do repot, slice the old plastic pot away rather than pulling the plant out, and keep the root ball 100% intact. Only upgrade the pot size by 1-2 inches (2.5-5 cm).

Method
Repotting guidance combines root crowding, drying speed, season and plant type. Most plants should move only one pot size up to prevent waterlogged excess mix.

Visible baseline values
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 |
|---|---|---|
| Visible roots | Root visibility increases repot urgency score by about 30 points. | Monitor season and watering speed before repotting. |
| Root bound | Root-bound status increases repot urgency score by about 60 points. | Move up gradually rather than jumping several pot sizes. |
| Root rot | Root rot triggers inspection even if pot size is otherwise adequate. | Use same size or smaller pot after trimming damaged roots. |
Formula summary: Repotting guidance combines root crowding, drying speed, season and plant type. Most plants should move only one pot size up to prevent waterlogged excess mix.
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
The #1 cause of Bougainvillea death is aggressive repotting.
The Fragile Root System
Unlike many plants that enjoy having their roots teased apart, Bougainvillea roots will snap. They prefer to be slightly root-bound (which actually encourages blooming). Never bare-root a Bougainvillea. Gently place the intact root ball into the new pot and backfill with fast-draining soil.
