Faucaria Tiger's Jaw — Toothy Succulent Complete Care Guide

Faucaria tigrina looks like tiny green jaws lined with teeth. Learn to grow this fascinating South African succulent with its dramatic toothed leaves and yellow daisy flowers. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Faucaria tigrina features fleshy triangular leaves lined with soft tooth-like projections along the margins. The teeth are soft and flexible, not sharp — they are a mimicry adaptation to resemble open animal jaws. Stays small at 3-4 inches across making it perfect for windowsills and small containers. Produces bright yellow daisy-like flowers in autumn that are large relative to the plant's small body size. A winter-growing mesemb relative that performs best in cooler months and rests in summer heat. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Summer overwatering during the natural rest period causes the fleshy bodies to split open or rot. Insufficient light causes the jaw-like leaf pairs to elongate and lose the compact toothy appearance. Heavy soil stays wet too long for this species adapted to sandy mineral substrates in its South African habitat. Extreme heat above 95°F combined with humidity can trigger sudden rot in otherwise healthy plants. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Provide full sun or the brightest light available to maintain compact jaw-shaped growth. Water moderately during the autumn-winter-spring growing season, letting soil dry between waterings. Reduce watering significantly in summer, giving just enough to prevent severe shriveling. Use a very gritty mineral-heavy soil mix with excellent drainage — pumice, sand, and perlite based. Repot every 2-3 years in spring as the clustering plant fills its container. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
