Tiger's Jaw: This plant forms clumps and appears almost stemless. Its common name, "tiger's jaw," comes from its thick, yet soft, tooth-lined leaves, which are grayish-green and resemble open jaws.
Tiger's jaw exhibits moderate disease resistance and is more sensitive to humidity. It becomes vulnerable to disease in high-humidity conditions and is prone to root rot during dormancy. In terms of care, Tiger's jaw is drought tolerant but requires more water during the growing season. Watering should be greatly reduced or stopped entirely while it is dormant. Tiger's jaw is appropriate for people with some growing experience, though it can be challenging to care for, particularly during dormancy. It is especially suited to those who can dedicate time to its care during the winter months.
How to keep Faucaria Tigrina.
Light
Tiger's jaw does well in full-day sunlight, though it does not always require sun for the entire day. Too much sun can cause leaf burn, and too little light can hinder growth. Since it comes from a habitat with abundant sunlight, tiger's jaw does not need to be shielded from the sun's rays.
Water
Tiger's Jaw, a plant native to arid regions, is well-adapted to thrive in drought conditions due to its ability to efficiently store water. It requires watering only every 2-3 weeks. When grown outdoors, Tiger's Jaw prefers well-draining soil to prevent root rot, showcasing its natural adaptation to dry environments.
Humidity
This plant will thrive in moderate humidity, which is probably the level in your home. However, misting it a few times a week can be very beneficial. Make sure the room has good ventilation.
Temperature
In its natural habitat, tiger's jaw favors warm conditions of 20 to 38 ℃ (68 to 100.4 ℉). For best growth, keep it at 23 to 27 ℃ (73.4 to 80.6 ℉) throughout the year. However, in winter it can tolerate slightly cooler temperatures down to 15 to 18 ℃ (59 to 64.4 ℉).
Fertilizer
For Tiger's jaw, apply light doses of fertilizer one to two times a year during the growing season. Avoid fertilizing in winter or summer when it is dormant. Reduce fertilizer for repotted plants and wait a couple of months after repotting before fertilizing. Fertilizing supports healthy growth and encourages blooms.
Pruning
To maintain the shape of a tiger's jaw plant, prune any unnecessary or dense branches in the spring and autumn using a knife or scissors. For propagation, cut sturdy stems with 5-6 leaves.

Use either tap water or distilled water. 4. Avoid watering from overhead. 5. Instead, water at the base of the plant, applying water slowly and evenly across the soil surface. 6. This will keep the soil consistently moist without wetting the above-ground parts of the plant. 7. Continue watering until you see a light stream of excess water draining from the pot's hole.
Why is it necessary to fertilize my Tiger's jaw?
To support healthy growth, it is beneficial to fertilize Tiger's jaw, which not only stores water and nutrients but also benefits from plant food applied during the growing season. Additionally, fertilizing can prompt mature specimens to produce blooms during this time.
What are the sun requirements for planting Tiger's Jaw?
Tiger's Jaw, known botanically as Faucaria tigrina, requires specific sunlight conditions to thrive. It is best suited for environments that provide full sun, which means the plant should receive more than 6 hours of sunlight daily. However, it can also tolerate partial sun conditions, entailing about 3-6 hours of sunlight. It's essential to observe how sunlight moves through your garden or growing space, ensuring that your Tiger's Jaw gets the ideal balance of light and shade to promote its health and happiness.
What are the ideal growth temperatures for Tiger's Jaw?
Tiger's jaw, or Faucaria tigrina, thrives in warm environments, flourishing best within a temperature range of 20 to 38°C (68 to 100.4°F). To promote optimal growth, maintaining a constant temperature between 23 to 27°C (73.4 to 80.6°F) across all seasons is recommended. Despite this preference for warmth, during the winter months—which mark the plant's growing season—it can withstand slightly cooler temperatures, from 15 to 18°C (59 to 64.4°F). To ensure its continued growth during these cooler periods, it's crucial to keep temperatures above 20°C, particularly when the outdoor temperature falls below 5°C, at which point the plant should be moved indoors to a well-lit area. Adjust watering practices based on temperature changes, increasing during warmer periods and decreasing as temperatures approach 5°C. If necessary, utilizing a sheltered outdoor area or a temporary greenhouse can provide the required protection and moisture levels for those choosing to overwinter the plant outside.
What should I do if I give my Tiger's jaw plant too much water or too little water?
A Tiger's jaw plant being overwatered is more common than it being underwatered, and overwatering is very harmful to the plant's health and can cause it to die quickly. To avoid overwatering, you should wait for the soil to dry completely before watering it again. Many people make the mistake of watering the plant incorrectly, especially when it goes into dormancy. So, we will focus on how to fix overwatering. When you notice signs of overwatering in your Tiger's jaw plant, it is best to remove it from its current pot. Then, examine the roots and remove any that show signs of rot or other moisture-related diseases. Some roots may need to be removed, but others can be cleaned and will recover. Afterward, repot the plant in soil that has good drainage to reduce the chances of future overwatering. While it's unlikely, underwatering can also happen. If this occurs, simply water your plant a bit more often, being careful not to overcompensate and overwater it.
What is the ideal time to put fertilizer on my Tiger's jaw plant?
Tiger's jaw plants require a light amount of fertilizer during their growing season, which is typically in the spring and autumn. It is recommended to fertilize them 1-2 times a year. However, it's important to note that they do not need fertilizer during their dormant periods in winter and summer. If you have recently repotted your Tiger's jaw, be cautious when applying fertilizer and reduce the amount. It's also advisable to wait a few months after repotting before starting to fertilize.
How does Tiger's Jaw respond to sunlight and artificial lighting?
Tiger's Jaw is adaptable to a day full of sun exposure but does not necessarily need sunlight all day long. Excessive sun exposure can cause leaf burn, while inadequate light may stunt the plant's growth. Originating from a sunlight-rich environment, Tiger's Jaw does not require protection from sun exposure. For indoor plants where natural sunlight may be insufficient, especially in winter or darker spaces, artificial lighting can be a beneficial alternative. Adequate artificial lighting promotes faster and healthier growth, with LED lights being a favorable choice for indoor plant lighting due to their customizable light wavelengths. Full sun plants need 30-50W/sq ft of artificial light, partial sun plants require 20-30W/sq ft, and full shade plants need 10-20W/sq ft. Aim to place artificial lights 12-36 inches above the plants, mimicking natural sunlight as closely as possible, and ensure plants receive 8-12 hours of light per day.
How should you care for Tiger's Jaw in low temperature conditions?
Tiger's jaw shows poor tolerance to extremely cold temperatures, with its optimal thriving range being 20°C to 38°C. It's vital to keep it above 5°C during winter to prevent damage. Exposure to temperatures below 1°C can cause leaves to show signs of water-soaked necrosis and wilting. Mild frost damage might not show immediate symptoms, but can lead to significant wilting and leaf drop within a week. If frostbite occurs, the frostbitten areas should be trimmed off and the plant moved indoors to a warmer environment or protected within a makeshift greenhouse. For indoor care, placing the plant near a south-facing window ensures it receives enough sunlight, while those opting for a greenhouse setup should monitor ventilation to prevent decay from poor airflow.
How often do I need to water my Tiger's jaw plant?
Tiger's jaw is a succulent plant that requires minimal water due to its origins in a hot and arid region. To care for this plant properly, allow the soil to completely dry out between waterings, which usually takes around two weeks to a month. The frequency of watering varies with the seasons. During spring and summer, when the plant is active, it may take 2-3 weeks for the soil to dry completely, so you can water accordingly. In the summer, the soil may dry out faster. However, when the temperature drops below 60 degrees or exceeds 85 degrees Fahrenheit, the plant enters a dormant or semi-dormant state and does not require additional watering. Instead, reduce or stop watering to maintain dry soil until the temperature becomes suitable for growth, and then resume watering.
When is it not a good time to fertilize my Tiger's jaw plant?
Tiger's jaw, like other plants, goes through a dormancy period. During this time, you should avoid fertilizing. In both summer and winter, the plant stops growing, so it's best to refrain from using fertilizer then. Additionally, it's recommended to wait a few months after repotting in the spring before resuming fertilizer applications.
What are the symptoms of insufficient or excessive light exposure in Tiger's Jaw?
Tiger's Jaw exhibits specific symptoms under suboptimal lighting conditions. Insufficient light can lead to lighter-colored new leaves, indicating a lack of chlorophyll and essential nutrients, and leggy or sparse growth, where the plant becomes stretched and weak. Alternatively, excessive light can result in chlorosis, causing leaves to lose their green color and turn yellow; sunscald, which manifests as pale or bleached areas on plant tissue; leaf curling, a defense mechanism to minimize sunlight exposure; wilting from increased water loss; and leaf scorching, characterized by dry, brown edges on leaves. These symptoms can significantly affect the plant's health and appearance.
How does high temperature affect Tiger's Jaw and what are the solutions?
During the hot summer months, it's essential to monitor and manage the temperature surrounding Tiger's jaw to prevent it from exceeding 38°C, as temperatures above 43°C can trigger dormancy and increase the plant's susceptibility to rot in humid conditions. To mitigate these risks, remove any dry or rotting parts of the plant promptly. Transferring the plant to a partially shaded area can offer protection from the intense direct sunlight experienced during midday and the afternoon. Moreover, it's advisable to cease watering the plant until temperatures drop to cooler, more manageable levels.
