Drimys winteri
Winter's bark · Canelo
Description
Source: leafsnapDrimys winteri, the winter's bark or canelo, is a slender tree in the family Winteraceae, growing up to 20 m (66 ft) tall. It is native to the Magellanic and Valdivian temperate rain forests of Chile and Argentina, where it is a dominant tree in the coastal evergreen forests. It is found below 1,200 m (3,900 ft) between latitude 32° south and Cape Horn at latitude 56°. In its southernmost natural range it can tolerate temperatures down to −20 °C (−4 °F). The plant is renowned for its phenotypic plasticity being able to grow in different sites from "extreme arid zones to wetlands along Chile". The tree does also grow in places with various types and degrees of competition from other plants.The leaves are lanceolate, glossy green above, whitish below and can measure up to 20 cm (8 in). The flowers are white with a yellow center, and consist of a great number of petals and stamens. The fruit is a bluish berry. The height–diameter relation of D. winteri varies greatly. There is for example more spread in D. winteri height–diameter relations than for Nothofagus species. Part of the spread can be explained as reflecting higher tree density that correlates with larger heights for a given diameter. Within its range D. winteri is more frost-tolerant than naturally occurring conifers and vessel-bearing angiosperms such as the Nothofagus. This challenged conventional views that plants without vessels such as D. winteri would be biological relicts poorly adapted to cold.The canelo is the sacred tree of the Mapuche, who associated it with "good, peace and justice".
Care Guide
💧 Water
Winter's bark comes from cool temperate rainforests and thrives in consistently moist soil, although it can tolerate moderate drought. To keep it well-hydrated without causing waterlogging, it's best to water it every 1-2 weeks. While it is generally grown outdoors, mulching during the growing season can help retain moisture around the plant.
How should I water my Winter's bark plant?
Watering your Winter's bark is simple and versatile. You can use any watering tool such as watering cans, hoses, or even cups. Make sure to water directly onto the soil and ensure that all areas of the soil are evenly moistened to provide water to the entire root system. Using filtered water is preferable to tap water, as tap water may contain harmful particles. Additionally, it is best to use water at or slightly above room temperature to avoid shocking the Winter's bark. However, the Winter's bark is generally resilient and will respond well to any type of water.
What do I need to do if I give too much or too little water to my Winter's bark?
Outdoor plants, especially newly planted ones or seedlings, are prone to lack of watering. It is important to water them enough for a few months until they are established. Once the roots are established, Winter's bark can rely on rain. When Winter's bark is planted in pots, overwatering is a common issue. If you accidentally overwater your plant, there are steps you can take to remedy the situation. First, stop watering your plant immediately to minimize the effects of overwatering. Then, remove the Winter's bark from its pot to inspect its roots. If you don't find any signs of root rot, you can put the plant back in its pot. However, if there are signs of root rot, trim away the affected roots and consider applying a fungicide to prevent further damage. Finally, repot the Winter's bark in well-draining soil. In the case of underwatering, simply water the Winter's bark more frequently. This is an easy fix, as the plant's leaves will droop, dry out, and fall off when underwatered. The leaves will quickly regain their fullness after sufficient watering. It is important to correct your watering frequency as soon as you notice symptoms of underwatering.
How often do I need to water my Winter's bark?
To properly care for outdoor plants, rainfall usually provides enough water. However, if your area lacks rainfall, you need to water your plants adequately every 2 weeks in the spring and fall. In the summer, you'll need to water more frequently. During the slower growth period in winter, water sparingly, and you may not need to water at all. If your Winter's bark is young or newly planted, water more often to help it establish and grow into drought-tolerant plants. For potted plants, there are two ways to determine watering frequency for Winter's bark. The first is to follow a set schedule, watering once a week or every other week. However, this might not be ideal for the specific conditions of your plant's environment. Watering frequency can also change with the seasons. During summer, when water needs are highest, a set schedule may not be enough. Alternatively, you can gauge watering based on soil moisture. Wait until the top two to four inches of soil have dried out completely before watering again.
How much water does my Winter's bark plant need?
When watering your Winter's bark, you don't always need to give it a lot of water. If only a few inches of soil have dried since the last watering, you can support healthy growth by giving it about five to ten ounces of water. You can also determine the amount of water based on the moisture in the soil. Keep track of how many inches of soil have dried between waterings. To ensure your Winter's bark gets enough moisture, water enough to moisten all the dry layers of soil. If more than half of the soil has dried out, consider giving more water. In such cases, continue watering until you see excess water draining from the pot's drainage holes. If your Winter's bark is planted in a rainy area outdoors, it may not need additional watering. When the Winter's bark is young or establishing, make sure it receives 1-2 inches of rain per week. As it grows and establishes, it can rely entirely on rainwater. Only when the weather is hot and there is no rainfall for 2-3 weeks, consider giving it a full watering to prevent stress.
How can I know if I'm giving enough water to my Winter's bark plant?
Overwatering is a common issue for Winter's bark plants, but there are clear signs to watch for. If your Winter's bark is overwatered, its leaves will turn yellow and possibly fall off. The plant's structure may start to shrivel, and it could develop root rot. On the other hand, if your Winter's bark is underwatered, it will begin to wilt and its leaves may become brown and brittle. Regardless of whether you see signs of overwatering or underwatering, it's important to take action and restore the plant's health.
☀️ Light Partial sun
Winter's bark grows best in locations that receive a mix of light and shade during the day. It is, however, hardy enough to tolerate a full day of sun. Too little light can inhibit its growth, while excessive exposure may scorch the leaves. The environment it comes from displays a similar light pattern.
What are the sunlight requirements for Winter's bark?
Winter's bark requires a mix of light and shade throughout the day to thrive optimally, but it is resilient enough to withstand a full day of sun. Its growth may be stunted by insufficient light, while overexposure can lead to leaf burn. Specifically, 'Partial sun' is defined as about 3-6 hours of sunlight, and 'Full sun' is above 6 hours of sunlight. Observing the movement of sunlight through your garden helps in selecting spots that provide the perfect balance of light and shade, ensuring the plants' wellbeing.
How does artificial lighting benefit indoor plants, and what are some guidelines for using it?
Indoor plants require adequate lighting for optimal growth, especially when natural sunlight is insufficient, like in winter or less sunny spaces. Artificial lights, such as LEDs, are beneficial as they can be customized to provide specific wavelengths needed by the plants. 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 light. The light source should be placed 12-36 inches above the plant to mimic natural sunlight and should be left on for 8-12 hours per day to imitate the length of natural daylight hours, promoting faster and healthier growth.
What are the symptoms of light deficiency in Winter's bark?
When Winter's bark is grown indoors with insufficient light, it may exhibit symptoms such as small leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, and lighter-colored new leaves. These symptoms indicate the plant's struggle with adapting to low light conditions, entering a survival mode that delays its growth and affects leaf production and coloration adversely.
What are some common symptoms of overexposure to sunlight in plants, and how does it affect Winter's bark?
Overexposure to sunlight can result in a range of symptoms including chlorosis, where the leaves lose their green color and turn yellow; sunscald, appearing as pale or necrotic areas on plant tissue; leaf curling, as a method to minimize water loss; wilting, due to increased transpiration leading to insufficient hydration; and leaf scorching, characterized by brown, dry edges on leaves. These conditions threaten the plant's ability to photosynthesize and maintain overall health.
What are the recommended solutions for addressing light-related issues in Winter's bark?
To optimize Winter's bark's growth in response to light-related issues, consider shifting the plant to sunnier spots gradually, allowing it to adapt to more light over time. For indoor plants, use a desk or ceiling lamp for at least 8 hours daily, or invest in grow lights if the plant is large. Outdoors, move plants gradually to sunnier locations to prevent sunburn. If sunlight is obstructed, prune blocking branches or transplant smaller plants during their dormant period to areas with better sunlight and drainage. It's important to note that parts of the plant affected by insufficient sunlight may not recover fully, but new growth should be healthy with increased light exposure.
🌡️ Temperature 15–35°C
Winter's bark originates from regions with mild temperatures, ideally ranging from 59 to 95 °F (15 to 35 ℃). It prefers that temperature band for the duration of the growing season. In colder areas, protective measures like windbreaks or planting close to a warm wall are recommended.
What are the ideal growing conditions for Winter's Bark?
Winter's Bark, scientifically known as Drimys winteri, thrives in moderate temperatures, ideally between 59 to 95 °F (15 to 35 °C) during the growing season. It is native to environments with these moderate temperature ranges and exhibits strong cold resistance. While special frost protection measures are not typically necessary, in climates where winter temperatures are expected to drop below -15°C, it's crucial to provide cold protection by wrapping the trunk and branches with non-woven fabric or cloth. Additionally, to combat dry conditions during winter and early spring, watering the plant abundantly before the first freeze in autumn, ensuring the soil remains moist and enters a frozen state, is recommended. For colder climates, employing windbreaks or situating the plant near a warm wall can offer added protection.
How does low temperature affect Winter's Bark, and what are the solutions?
Winter's Bark is quite cold-tolerant and performs best when temperatures are maintained above 15°C. During winter, it is advisable to keep it above -10°C to prevent damage. Should temperatures fall below -15°C, though there may not appear to be immediate damage during the winter, you might observe that the branches become brittle and dry come spring, failing to produce new shoots. To address this, prune away any dead branches that have not produced new leaves in the spring. This helps the plant to recover and encourages healthy growth.
How does high temperature affect Winter's Bark and what are the solutions?
During summer, it's important to ensure that the temperature surrounding Winter's Bark does not exceed 35°C. Should temperatures rise above 41°C, the plant's leaves may lighten in color, and the tips can become dry and withered, making the plant more susceptible to sunburn. To mitigate these effects, trim away the sunburned and dried parts. Move the plant to a shaded area, away from the midday and afternoon sun, or utilize a shade cloth to protect it. Additionally, watering the plant in the morning and evening will help keep the soil moist and support the plant's health in high temperatures.

🌱 Fertilizer
Timing is important when fertilizing Winter's bark. Apply fertilizer in early spring and continue monthly until early summer. Fertilizer promotes attractive blooms and supplies energy both during dormancy and periods of active growth.
Why should I put fertilizer on my Winter's bark?
Fertilizing Winter's bark is important for multiple reasons. Firstly, it helps the tree produce beautiful blooms. To ensure these blooms, it is best to fertilize in early spring. Secondly, fertilizer provides ample energy to the tree during dormant growth phases. By giving it extra nutrients during fall planting or late spring, the tree can store more energy to use when it resumes active growth.
When should I fertilize my Winter's bark?
When fertilizing Winter's bark, timing is crucial. If you apply fertilizer too early while the Winter's bark is still dormant, it will not be effective and will be washed away by rainwater, leading to waste and pollution. To ensure effective fertilization, the first application should be done in early spring, followed by monthly applications until early summer.
When is the best time to not fertilize my Winter's bark?
To ensure optimal growth and flowering of Winter's bark, it is important to be mindful of the fertilizer used. Avoid high levels of nitrogen, as this can result in an abundance of leaves but few blooms. Instead, opt for a fertilizer with a lower nitrogen content in comparison to other nutrients. Timing is key when it comes to fertilizing Winter's bark. After early autumn, refrain from fertilizing to prevent excessive growth right before winter. Similarly, avoid fertilizing during hot and dry periods, as dry soil is less effective at delivering the fertilizer and can stimulate growth that requires additional water that may not be readily available. It is advised to apply fertilizer earlier in the season when temperatures are cooler. One additional consideration is that Winter's bark can absorb fertilizer intended for nearby plants or lawns, so be cautious to prevent inadvertently providing the tree or shrub with an excessive amount of fertilizer.
What kind of fertilizer does my Winter's bark tree need?
To optimize the growth of Winter's bark, it is recommended to use a fertilizer that provides a balanced mix of essential plant nutrients. Ideally, the fertilizer should have slightly higher levels of phosphorus. Alternatively, some gardeners prefer to enhance the soil for Winter's bark by incorporating organic materials like compost, worm castings, and manure. Experienced gardeners may choose to supplement water-soluble fertilizers containing phosphorus once or twice when the flower buds start to emerge. This practice promotes better flower development, leading to larger and longer-lasting blooms. Various forms of fertilizers are available for Winter's bark and can be effective. However, liquid or powdered fertilizers are often considered the best options. Irrespective of the form chosen, it is important to dilute the fertilizer and apply it while watering the Winter's bark.
How can I add nutrients to my Winter's bark?
To properly fertilize your Winter's bark, it's crucial to follow the directions for the specific type of fertilizer you are using. Avoid over-fertilizing by determining the correct amount to apply. A general guideline is to use the age of the tree or its trunk diameter to estimate the appropriate amount of fertilizer. Typically, you can estimate using one-tenth of a pound of fertilizer per year or per inch of trunk, up to a maximum of one pound. When applying granular or organic fertilizers like blood meal, sprinkle the substance around the base of the tree, extending it all the way to the drip line (the area below the farthest-reaching branches). Be careful not to let the fertilizer come in contact with the trunk. Over time, the granules will break down and filter into the soil, getting absorbed by the roots. After fertilizing, spread a layer of compost around the tree's base, approximately an inch deep, and make sure to thoroughly water the area.
🪴 Pot & Repot 2-3 years
Repot Winter's bark every 2-3 years in early spring, using a pot slightly larger than the last one. Use well-draining soil and make sure the new pot has drainage holes. After repotting, place the plant in indirect light and keep the soil moist to help it recover. Consistent care will support its optimal growth.
✂️ Pruning
Winter’s bark boasts aromatic bark and vibrant flowers. To improve airflow and shape, it should be pruned between early and late winter by removing dead wood and overcrowded branches. This timing minimizes sap bleeding and encourages spring growth, thereby enhancing the plant's resistance to disease and overall vitality.
