Care Guide
💧 Water Every 3 days
The beefsteak plant, originally from Asia, thrives in humid conditions. Although it can tolerate moderate drought, it prefers consistent moisture, so it should be watered twice a week. When grown indoors, it benefits from well-draining containers to prevent root waterlogging.
How should I water my Beefsteak plant to keep it healthy?
The Beefsteak plant not only has specific water preferences, but it also cares about how you water it. If you don't use the right technique, you could harm your tomatoes. The best way to water a Beefsteak plant is to apply water directly to the soil, gently and slowly. Avoid pouring all the water at once or using overhead watering. While watering slowly, make sure to water deeply to ensure the entire soil where your Beefsteak plant grows is adequately moist.
What should I do if I give my Beefsteak plant too much or too little water?
If you realize that you have given too much water to your Beefsteak plant and are worried about the risk of disease, take immediate action. The best solution for an overwatered plant is to remove it from its current spot and allow its roots to dry a bit before replanting it in a different location with well-draining soil. If you are growing the plant in a pot, consider moving it to a pot with better drainage. On the other hand, if you have underwatered your plant, simply increase the frequency of watering.
How many times should I water my Beefsteak plant?
Beefsteak plants have high water needs during the growing season. To meet these needs, it is recommended to water them frequently throughout spring and summer. At the beginning of the growing season, water your Beefsteak plant once or twice a week. As the season progresses, increase the frequency of watering. In summer, you may need to water it twice a day or more, depending on the weather. Once the major growth phases are complete, reduce watering to once a week until the end of the growing season.
How much water does my Beefsteak plant require?
Beefsteak plants are very popular among professional and amateur gardeners, and as a result, we have a good understanding of how to take care of them. One important aspect is knowing how much water they need. On average, a Beefsteak plant should receive about 1 - 1.5 inches of water per week, which should be evenly distributed through your weekly watering routine. During hotter weather, you may need to increase the amount of water, but in most cases, two inches per week is a good starting point.
How can I know if I'm giving my Beefsteak plant enough water?
Both underwatering and overwatering can be problems for your Beefsteak plant, and they can both show similar symptoms. For instance, both overwatering and underwatering can cause discoloration and wilting of the foliage. When your Beefsteak plant is underwatered, you will notice its leaves curling and drooping initially, and eventually, the leaves will become less vigorous. Underwatering can also lead to stunted growth and poor overall development because this plant requires a significant amount of water. On the other hand, overwatering is more likely to result in diseases such as rot and can create unpleasant smells from the soil. The symptoms of underwatering manifest faster than those of overwatering. Overwatering can also be identified by the presence of standing water or waterlogged soils.
☀️ Light Full sun

For indoor plants lacking natural sunlight, especially during winter or in less sunny spaces, artificial lighting such as LED lights can provide the needed wavelengths for optimal growth. Full sun plants require 30-50W/sq ft, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft of artificial light, placed 12-36 inches above the plant for 8-12 hours per day.
What are some common symptoms of inadequate lighting for Beefsteak plants?
When the Beefsteak plant is grown indoors or in conditions of limited light, it may show symptoms such as smaller new leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, and lighter-colored new leaves. These symptoms indicate a deficiency in light, which is crucial for the plant's photosynthesis and overall health. In excessive sunlight, the plant may experience chlorosis, sunscald, leaf curling, wilting, and leaf scorching, pointing to the importance of balancing sunlight exposure.
What solutions can help Beefsteak plants thrive in inadequate lighting conditions?
For optimal growth, Beefsteak plants with inadequate lighting can benefit from gradual relocation to sunnier spots, aiming for at least 6 hours of direct sunlight daily. Indoors, using artificial lights like desk or ceiling lamps for at least 8 hours daily, or investing in professional plant grow lights, can provide the necessary light. Outdoors, gradually moving the plants to areas with more sunlight, while avoiding sudden changes to prevent sunburn, is advisable. Additionally, reducing obstacles to sunlight, such as pruning obstructive branches, or transplanting smaller plants to better-lit locations, can significantly benefit the plant's health and growth.
🌡️ Temperature 15–35°C
Beefsteak plant comes from a naturally warm climate and grows best at temperatures between 68 and 95 °F (20 to 35 ℃). During colder seasons, make sure to adjust room temperatures to imitate its native environment.
What is the ideal temperature range for the Beefsteak plant?
The Beefsteak plant, or Perilla frutescens, thrives in a naturally warm climate with ideal temperatures ranging between 68 to 95°F (20 to 35°C). To ensure optimal growth, it's important to maintain temperatures above 20°C, especially during winter cultivation. The plant requires protection from cold, with minimum temperatures kept above the freezing point to avoid frost damage. In regions where the outdoor temperature drops below -5°C (25°F) during winter, it's advisable to bring the plant indoors or provide insulation with a temporary greenhouse or wrapping materials such as plastic film or fabric.
How does the Beefsteak plant react to low temperatures and how can it be protected?
The Beefsteak plant has a moderate tolerance to low temperatures, performing best when kept between 20°C and 35°C. Exposure to temperatures below 0°C can lead to darkening leaves, and when it goes below -15°C, it may suffer from water-soaked necrosis, wilting, and eventual browning. To protect and recover the plant from frost damage, trim the frost-damaged parts and move it to a warmer indoor space or set up a temporary greenhouse. Placing it near a south-facing window ensures it gets sufficient sunlight, and if light is inadequate, supplemental lighting can be used.
How should the Beefsteak plant be cared for during high temperatures?
During the summer season, it's crucial to keep the Beefsteak plant's environment below 35°C to avoid inhibiting its growth. Temperatures exceeding 41°C can cause the plant to grow slowly, lighten the color of its leaves, and increase susceptibility to sunburn. To mitigate high temperature stress, trim away sunburned and dried parts of the plant. Relocate the plant to an area that's shaded from the harsh afternoon sun. Additionally, watering the plant in the morning and evening helps keep the soil adequately moist, providing further relief from high temperatures.

🌱 Fertilizer
To maximize yield, the Beefsteak plant benefits from regular applications of a balanced fertilizer, particularly one high in nitrogen. Apply fertilizer before planting, at planting, and when seedlings are 2 inches tall. Adding compost or manure also provides a continuous nutrient supply. Insufficient nutrients in the soil lead to underdeveloped leaves and stems, inferior flavors, thin stems, and a potentially bitter taste.
Why should I add fertilizer to my Beefsteak plant?
The beefsteak plant is grown for its edible leaves and shoots, which means it needs enough nutrients for great flavor and a large harvest. If it's grown in soil lacking nutrients, the leaves and stems won't develop properly and the taste won't be as good compared to plants grown in better conditions. Thin stems and a bitter taste are likely outcomes. Fertilization is even more important for container-grown plants because they don't have as much access to organic matter as those in the ground. To supplement your beefsteak plant in a pot, use a balanced liquid fertilizer.
When should I fertilize my Beefsteak plant?
To benefit your Beefsteak plant, there are several points when you should apply fertilizer during the growing season. Initially, when you are preparing the ground for planting, it is recommended to amend the soil with nutrient-rich organic material like compost or manure at least 2 to 8 weeks before planting. At planting time, you should amend the soil again using the same method. Once your seedlings emerge and grow to around 2 inches tall, you can apply the next dose of fertilizer. After that, you can regularly feed your Beefsteak plant with rich organic matter or a commercial fertilizer until it is ready for harvesting. The preferred schedule for fertilizing is every two to three weeks. Additionally, adding a layer of compost or manure around the plant is a good idea as it ensures a continuous supply of nutrients.
When is it not a good idea to fertilize my Beefsteak plant?
To ensure the health of the Beefsteak plant, avoid fertilizing it when the soil is dry. This plant needs ample water to effectively absorb nutrients. Additionally, it's important to refrain from using chemical fertilizers on this plant outside of the growing season. Doing so could introduce more fertilizer than the plant can utilize, potentially leading to groundwater contamination and soil contamination. Therefore, it's best to only fertilize the plant during its active growing periods.
What kind of fertilizer should I use for my Beefsteak plant?
To successfully grow Beefsteak plant, it is important to provide it with a balanced fertilizer. However, if the soil is already nutrient-rich, it may not require much fertilization. Organic fertilizers like fish emulsion, well-rotted manure, and compost or compost tea are highly effective for Beefsteak plant growth. If you prefer, you can use a fertilizer with a slightly higher nitrogen ratio as nitrogen promotes strong foliage development. To understand the nutrient ratios in a fertilizer mixture, look at the NPK number on the label. The best way to choose the right fertilizer for your Beefsteak plant is by conducting a soil test and comparing the results to the plant's requirements.
How should I help my Beefsteak plant grow better?
Before planting, it's important to mix compost or other organic fertilizers into the soil. This helps seedlings get off to a strong start and develop healthy roots. At the start of the growing season, you can layer compost or organic fertilizers and soil amendments around the bed. This allows nutrients to gradually be released into the soil over time. If necessary, you can also sprinkle a slow-release granular fertilizer onto the soil to supplement nutrients and promote leaf development. When it comes to liquid fertilizers, it's recommended to use them during regular watering. However, if you choose to use chemical fertilizers, be cautious not to overuse them and risk damaging your Beefsteak plant.
🪴 Pot & Repot
When repotting a Beefsteak plant, choose a pot that is 1-2 inches (2.5–5.1 cm) larger in diameter and that offers good drainage. Use a well-draining potting mix and consider adding perlite for extra drainage. Repot in spring or early summer, water thoroughly afterward, and place it in a shady location for the very beginning.
✂️ Pruning
The beefsteak plant is an aromatic herb prized for its culinary uses. To encourage bushiness, prune it in the spring by removing the top one-third of the plant and any dead stems. Be sure to clean your tools to prevent infections, and make cuts just above the leaf nodes to promote new growth and enhance the plant's flavor.
