Hypericum hircinum, also known as stinking tutsan, is a shrubby flowering plant in the St. John's wort family Hypericaceae.

Care Guide

💧 Water

Stinking tutsan thrives in dry conditions and is highly drought-tolerant. Water the plant every 2 to 3 weeks, making sure the soil dries out between watering sessions. During extended dry periods, keep an eye on soil moisture to ensure the plant stays properly hydrated, as it benefits from natural rainfall.

FAQ
How should I water my Stinking tutsan plant in the best way?

To ensure excellent root development, it is recommended to place a garden hose at the base of the plant. Be careful not to directly spray the leaves. Keep in mind that outdoor plants exposed to direct sunlight will need more water for the leaves. Using bubblers for each plant can help moisten the roots. Soaker hoses that cover the entire garden or bed can be used when adding or removing plants to encourage deep root growth. After watering, make sure to drain any excess water and allow the soil to dry before watering again. Watering at ground level will help prevent diseases. On a sunny day, it may be beneficial to spray the entire bush with water. Whether the plant is in a pot or in the ground, remember that Stinking tutsan prefers deep watering instead of light sprinkling.

What do I do if I give Stinking tutsan too much or too little water?

If you overwater a Stinking tutsan, the leaves may turn yellow, drop off, and become wilted. The plant might appear dull and unhealthy, with mushy stems. In this case, it's best to adjust your watering schedule. On the other hand, wilting can also be a sign of under watering. Underwatered leaves may turn crispy and dry, while overwatered leaves will be soft and wilted. If the soil is dry and watering is not enough, give the plant a full watering. However, even with enough water, the Stinking tutsan may still have dry and yellow leaves due to root damage. Once it has fully recovered, the yellowing of the leaves will stop. When keeping the Stinking tutsan indoors, always check the moisture levels in the pot to avoid overwatering. Look out for black spots, and if they are present, let the soil dry out for a few days before watering again. Overwatering can lead to root rot, so if you notice discolored and slimy roots, consider transferring the plant to a different pot. Always prevent root rot by avoiding overly soggy soil. When planting the Stinking tutsan outdoors, make sure to check the soil's moisture levels. If it's too dry, that could indicate underwatering, and the plant will require adequate watering to recover.

How frequently do I need to water my Stinking tutsan?

The Stinking tutsan prefers deep and infrequent watering, especially when planted in pots. Potted plants have limited water storage, so they dry out faster and need to be watered every 3 to 5 days in cold regions. Watering should be done in the morning when the soil is dry, and you can check if watering is needed by examining the top 2-3 inches of soil. If it's dry, give the plant a thorough watering. In hot weather, check the moisture level daily as the soil can dry out quickly. If you have a garden, irrigation is necessary, and in hot climates, watering once a week is recommended. However, avoid overwatering if there is already sufficient rainfall to prevent root rot. During the growing seasons (spring and fall), mulch can help conserve water when the plants are outdoors. Sandy soils drain faster, so more frequent watering is needed, while clay soils require less watering to prevent root rot. To keep track of watering, mark the date on the calendar and watch for drooping leaves as a sign that watering may be needed.

How much water does my Stinking tutsan plant need?

The Stinking tutsan generally needs about a gallon of water on a regular basis. For potted plants, water them deeply until you see water dripping out of the bottom of the pot. Allow the soil to dry before watering again. Use a water calculator or moisture meter to track the amount of water given to your plant each week. During the flowering period, provide plenty of water but then allow the moisture to evaporate to prevent root rot. If the Stinking tutsan is planted outdoors and receives adequate rainfall, it may not need additional watering. When the Stinking tutsan is young or newly planted, ensure it receives 1-2 inches of rain per week. As the plant grows, it can rely solely on rainfall. Only in hot weather or when there is no rain for 2-3 weeks, consider giving the Stinking tutsan a full watering during cooler parts of the day to prevent heat damage. Additional watering may be necessary during long dry spells.

Should I water my Stinking tutsan more often or less often depending on the time of year or the weather?

The Stinking tutsan prefers to be outdoors in rainy conditions but can tolerate dry weather if necessary. During the spring and fall, the soil should be kept moist but not too wet, and alternating between dry and moist conditions is beneficial. In the summer, hot weather can cause water to evaporate quickly, so extra watering may be needed if there is a lack of rainfall. In winter, less water is generally required as the plant goes dormant. Use a well-draining soil mix to allow for quick evaporation during this period. Once the plant begins to leaf out in spring, watering can be skipped, relying on fall and winter rains to keep it hydrated. Proper drainage is important, especially during winter, to avoid ponding or drought. For potted plants, ensure they have adequate root growth and water them well, especially in summer. Deep soaking once or twice a week is recommended, avoiding shallow sprinkles. Even during fall and winter dormancy, the plants shouldn't be allowed to dry out completely. Avoid overwatering to prevent the roots from sitting in water for prolonged periods, as this can lead to plant death. Applying mulch is also beneficial for reducing stress, conserving water, and promoting healthy blooms.

☀️ Light Full sun

St. John's Wort does best in spots that receive abundant sunlight for much of the day. It can tolerate reduced light, though this may somewhat impede its growth. In its native range, it prospers in areas with plentiful sun. Excessive exposure can cause leaf scorch, while too little light may lead to stunted growth and fewer flowers.

Ideal: Full sun
FAQ
What are the sunlight requirements for Stinking Tutsan?

Stinking Tutsan requires more than 6 hours of sunlight daily to qualify as being in full sun, while partial sun is about 3-6 hours of sunlight. It's important to note how sunlight moves through your garden, aiming for spots that provide the right balance of light and shade. This ensures the plants' happiness and health.

How does Stinking Tutsan react to sun exposure and shade?

Stinking Tutsan thrives best under unobstructed exposure to the sun's rays or in environments where sun exposure is mixed with some shade. It shows robust growth when it receives adequate illumination, although excessive sunlight can cause the plant to wither. Its resilience in its native habitat, under variable light conditions, allows it to tolerate less luminous settings.

How can artificial lighting benefit plants, particularly Stinking Tutsan?

Indoor Stinking Tutsan plants require sufficient lighting for optimal growth. In cases where natural sunlight is insufficient, artificial lights serve as a vital solution. LED lights are recommended because they can be customized to provide specific wavelengths needed by your plants. Full sun plants need 30-50W/sq ft, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft of light. The artificial light source should be placed 12-36 inches above the plant, mimicking natural sunlight conditions, and most plants benefit from 8-12 hours of light per day.

What are common symptoms of light deficiency in Stinking Tutsan?

Symptoms of light deficiency in Stinking Tutsan include new leaves growing smaller, leggy or sparse growth, faster leaf drop, slowed or halted growth, lighter-colored new leaves indicating a lack of chlorophyll, and conditions like chlorosis and sunscald. Sunscald is marked by pale or necrotic areas due to intense sunlight exposure, while chlorosis leads to yellowing leaves. Leaf curling, wilting, and leaf scorching are also symptoms; these indicate stress from excessive sunlight or inadequate light conditions.

What are the solutions for light-related issues in Stinking Tutsan?

To address light-related issues in Stinking Tutsan, gradually move plants to sunnier locations to ensure they receive at least 6 hours of direct sunlight daily. Use a south-facing window for maximum sunlight exposure or consider artificial lighting for indoor plants. For outdoor plants, avoid sudden changes in light intensity to prevent sunburn. Reducing obstructions and transplanting to sunnier locations with good drainage can also help. Note that parts of the plant affected by insufficient sunlight may not recover, but new growth should be healthy after adjusting light exposure.

🌡️ Temperature 5–35°C

St. John's Wort is highly adaptable to different climates, from very hot summers to cold winters. However, it still has an optimal temperature range for growth; if temperatures become too high, the plant can suffer heat and humidity stress that may lead to its death. In areas where temperatures near the lower limit of its cold tolerance, providing insulation is important to protect the plant.

Ideal temperature: 5–35°C
