Description
Source: leafsnapPersea borbonia or redbay is a small, evergreen tree in the laurel family (Lauraceae), native to the southeastern United States. It belongs to the genus Persea, a group of evergreen trees including bays and the avocado. Persea borbonia has several common names including tisswood, scrubbay, shorebay, and swampbay.
💡 Many birds, such as wild turkeys and bobwhite quail, eat the fruit. White-tailed deer and black bears consume both the fruit and the leaves. Additionally, the trees serve as a habitat for gray squirrels. Unfortunately, many of these trees are dying from laurel wilt, a fungal infection introduced by an ambrosia beetle that is native to India and Japan.

Care Guide
💧 Water Every 7 days
The Redbay tree is well-suited to humid environments and exhibits moderate drought tolerance. It thrives with balanced hydration and typically needs watering every 1-2 weeks. As an evergreen, it requires consistent soil moisture to maintain its foliage, especially when grown outdoors.
How should I water my Redbay tree?
Your Redbay is not particular about how it is watered, so you can use any common watering tool. Watering cans, hoses, or even cups will all work fine. Regardless of the tool, make sure you apply the water directly to the soil. Be sure to moisten all areas of the soil evenly so that the entire root system gets the water it needs. Using filtered water is helpful because tap water may have harmful particles. It's also a good idea to use water that is at or slightly above room temperature, as very cold or hot water can be a shock to the Redbay. However, the Redbay generally responds well to any type of water you use.
What do I do if I give my Redbay tree too much water or not enough water?
Plants that are outdoors, especially newly planted ones or seedlings, can be prone to not getting enough water. It's important to remember to water them regularly for the first few months while they are small or newly planted. Once the roots are established, Redbay plants can usually rely on rain for most of their water needs. If your Redbay is planted in pots, overwatering is more likely to happen. If you accidentally overwater your plant, there are steps you can take to fix the situation. First, stop watering the plant immediately to minimize the effects of overwatering. Next, remove the Redbay from its pot to inspect the roots. If you don't find any signs of root rot, you can return the plant to its container. However, if there is root rot, trim away the affected roots and consider using a fungicide to prevent further damage. Finally, repot the Redbay in well-draining soil. On the other hand, if your Redbay is underwatered, the solution is simple. Water the plant more frequently. When a Redbay is underwatered, its leaves may droop, dry out, and fall off. Once sufficient water is given, the leaves will quickly return to their fullness. It's important to correct your watering frequency as soon as you notice signs of underwatering.
How frequently should I water my Redbay plant?
If your area doesn't receive much rainfall, you'll need to water your outdoor plants every 2 weeks in the spring and fall, and more frequently in the summer. During the winter, when plants don't require as much water, water sparingly or not at all. Young or newly planted Redbay plants should be watered more often to help them grow and become drought tolerant. For potted Redbay plants, you have two options for determining watering frequency. One is to stick to a set schedule of once a week or once every other week. However, this may not take into account specific growing conditions. Alternatively, you can water based on soil moisture. Wait until the top two to four inches of soil have completely dried out before watering again.
How much water does my Redbay tree require?
When watering your Redbay, keep in mind that it does not always require a large amount of water. If only a few inches of soil have dried since the last watering, providing the Redbay with about five to ten ounces of water each time can support healthy growth. You can also determine the water volume based on the moisture of the soil. Take note of how many inches of soil have dried out between waterings. To ensure your Redbay receives sufficient moisture, water the plant enough to moisten all the layers of dry soil since the last watering. If more than half of the soil has dried out, it may be necessary to provide a larger amount of water than usual. In this case, continue watering until you see excess water draining from the pot's drainage holes. If your Redbay is planted in an area that receives ample rain, additional watering may not be needed. When the Redbay is young or newly planted, ensure it receives 1-2 inches of rain per week. As it grows and establishes itself, it can rely solely on rainwater. However, in times of hot weather and no rainfall for 2-3 weeks, consider giving your Redbay a thorough watering to prevent stress.
How can I know if I'm providing enough water for my Redbay plant?
Overwatering is a common issue for the Redbay plant, and there are clear signs to watch out for. If you overwater your Redbay, you will notice yellowing leaves and possible leaf loss. Additionally, the plant's structure may shrink, and there is a risk of root rot. On the other hand, if you underwater your Redbay, it will start to wilt, and the leaves may become brown and brittle. Regardless of whether you observe signs of overwatering or underwatering, it is important to take action and restore your Redbay's health.
☀️ Light Full sun
Redbay performs best when given plenty of sunlight, reflecting the conditions of its natural habitat. It can tolerate lower light levels, but this often leads to slower growth. Both too much and too little sunlight can produce unhealthy effects such as wilting or discoloration.
What are the sunlight requirements for Redbay?
Redbay thrives under conditions that mimic its natural growth environment, which involves abundant exposure to sunlight. It requires above 6 hours of sunlight to be classified as receiving full sun, and about 3-6 hours to be considered in partial sun. However, both overexposure and underexposure to sunlight can result in signs of distress such as wilting or discoloration, indicating the need for a balance that ensures the plant's health and happiness.
How does artificial lighting affect Redbay growth indoors?
When natural sunlight is inadequate, especially during winter or in less sunny spaces, artificial lighting becomes critical for the growth of indoor Redbay plants. Adequate artificial lighting promotes healthy and fast growth. LED lights are recommended as they can be customized to provide specific wavelengths needed by plants. Full sun plants need 30-50W/sq ft of light, partial sun plants require 20-30W/sq ft, and full shade plants need 10-20W/sq ft. The light source should be placed 12-36 inches above the plant, mimicking natural sunlight as closely as possible, and kept on for 8-12 hours per day to ensure optimal growth.
What are some symptoms of inadequate sunlight exposure in Redbay?
In conditions of poor lighting, Redbay may show several symptoms indicating light deficiency. New leaves might grow smaller and the plant may exhibit leggy or sparse growth, leading to a stretched-out appearance. There might be faster leaf drop, slower or no new growth at all, and the development of lighter-colored new leaves. Chlorosis, or yellowing of leaves due to the breakdown of chlorophyll, and sunscald, where leaves show pale, bleached areas due to intense sunlight, are other symptoms. Additionally, leaf curling, wilting, and leaf scorching might occur as defense mechanisms or direct impacts of inadequate light exposure.
What solutions exist for addressing light-related issues in Redbay plants?
To mitigate light-related issues in Redbay, it's beneficial to gradually adapt the plant to brighter conditions. For indoor plants, progressively move them to locations with at least 6 hours of direct sunlight daily, possibly near a south-facing window, and consider using artificial light sources like desk or ceiling lamps or professional grow lights for at least 8 hours a day. For outdoor plants, transition them to sunnier spots weekly to avoid shock. Reduce sunlight obstructions by pruning surrounding foliage if necessary. For small plants with insufficient sunlight, transplanting during their dormant period into sunnier, well-drained locations might be effective. It's important to understand that parts of the plant already damaged by poor light conditions may not recover, but new growth should be healthy with increased light exposure.
🌡️ Temperature 15–37.8°C
Redbay prefers a relatively mild environment; its natural growth conditions correspond to temperature requirements with a preferred range of 59 to 100 ℉ (15 to 38 ℃). To achieve optimal growth, it is recommended that temperatures be adjusted between seasons as needed.
What is the preferred temperature range for Redbay?
Redbay thrives in a relatively mild environment, with its native growth environment falling within a preferred temperature range of 59 to 100°F (15 to 38°C). To ensure optimal growth, it's suggested to adjust the temperatures during different seasons as necessary, keeping in mind Redbay's moderate tolerance to both high and low temperatures.
Does Redbay require any special care during cold temperatures?
Redbay has some cold tolerance and generally does not require additional measures when temperatures are above -5°C. However, if temperatures are expected to drop below -5°C, temporary measures for cold protection should be taken, such as wrapping the plant with plastic film, fabric, or other insulating materials. These protective measures should be removed once the temperature rises again to prevent any potential damage to the plant.
How should Redbay be cared for in low temperature conditions?
In low temperature conditions, Redbay shows moderate tolerance, thriving best when temperatures are above 15°C. It should be kept above -5°C during winter. If temperatures fall below -10°C, the leaves may start to droop, with a potential for recovery in mild cases, but in severe cases, leaves will wilt and eventually fall off. Trimming off frost-damaged parts and wrapping the plant with materials such as non-woven fabric or cloth, while also constructing a wind barrier, can protect Redbay from cold winds.
What steps should be taken if Redbay is exposed to high temperatures?
During the summer, Redbay should be kept below 38°C to prevent stress from high temperatures. Exposure to temperatures above 43°C can cause the leaves to lighten in color, dry out at the tips, curl, and make the plant more susceptible to sunburn. To manage these issues, sunburned and dried-up parts should be trimmed away. Moving the plant to a shaded location, or using a shade cloth, can protect it from the harsh midday and afternoon sun. Additionally, watering the plant in the morning and evening helps keep the soil moist and reduces heat stress.
What is the botanical name of Redbay?
