Care Guide

💧 Water Every 7 days

The Be Still tree flourishes in tropical conditions with high humidity and consistent moisture. It should be watered every 2-3 weeks, allowing the soil to dry out slightly between waterings. During its dormancy period, the tree is sensitive to overwatering, so careful management is crucial to prevent root rot.

Suggested frequency: Every 7 days
FAQ
How should I water my Be Still tree?

Your Be still tree is not picky about how you water it, so you can use any common watering tool you have. Watering cans, hoses, or even cups will do the job. It's important to water the soil directly and make sure all areas are evenly moistened to provide enough water to the entire root system. Using filtered water is recommended to avoid harmful particles from tap water. It's also best to use water at room temperature or slightly warmer, as extremely cold or hot water can be a bit shocking to the Be still tree. However, the tree generally responds well to any kind of water you give it.

If I give too much or too little water to my Be still tree, what should I do?

Outdoor plants, especially newly planted ones or seedlings, are susceptible to lack of watering. It's important to water them enough for a few months while they are small or newly planted. Once the roots are established, these plants can rely on rainfall. When caring for potted plants, overwatering is a common issue. If you accidentally overwater your plant, quickly stop watering to minimize the effect. Take the plant out of its pot and check the roots for signs of root rot. If there is no root rot, you can return the plant to its pot. However, if there is root rot, trim affected roots and apply fungicide. Repot the plant in well-draining soil. On the other hand, if your plant is underwatered, simply water it more frequently. Underwatering can be easily corrected as the leaves will droop and dry out, but they will regain fullness after sufficient watering. Adjust your watering frequency promptly when you notice underwatering.

How much water does my Be still tree need?

Most outdoor plants can grow naturally with rainfall, but if your area lacks rainfall, you should water them adequately every 2 weeks in the spring and fall. In the summer, they will need more frequent watering. However, in the winter, when growth slows down and plants require less water, you should water them sparingly or not at all. If your Be still tree is young or newly planted, it will need more frequent watering to help it establish and become more adaptable and drought tolerant. For potted plants, there are two main ways to determine watering frequency for your Be still tree. The first method is to follow a predetermined watering schedule, such as watering once a week or every other week. However, this approach may not always be suitable as it does not consider the specific growing conditions of your Be still tree. Watering frequency can also vary depending on the season. During summer, when the plant's water needs are highest, a predetermined watering schedule may not be enough. An alternative method is to base your watering frequency on soil moisture. Ideally, you should wait until the top two to four inches of soil (around ⅓ to ½ depth of the pots) have completely dried out before watering again.

How much water does my Be still tree require?

When watering your Be still tree, you don't always need to use a lot of water. If only a few inches of soil have dried since the last watering, giving the tree about five to ten ounces of water is enough for 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 tree gets enough moisture, water until all the layers of dry soil are moistened. If more than half of the soil is dry, consider giving more water and continue until you see excess water draining from the pot's holes. If your Be still tree is planted in an area with abundant rain, it may not need extra watering. For young or newly established trees, make sure they receive 1-2 inches of rain each week. As they grow, they can rely on rainwater, only needing full watering during hot weather and extended periods without rainfall (2-3 weeks) to prevent stress.

How can I know if I'm giving enough water to my Be still tree?

The Be still tree is often affected by overwatering, which has distinct signs to look out for. Yellowing leaves and leaf drop are common indications of overwatering. Additionally, overwatering may cause the plant to shrink and can lead to root rot. On the contrary, an underwatered Be still tree will start to wilt and may have brown or brittle leaves. Whether you notice signs of overwatering or underwatering, it is important to act promptly and restore your Be still tree's health.

☀️ Light Full sun

The be still tree does best when it gets a generous amount of sunlight each day. Its native habitat has conditioned it to do well under those circumstances. Too little light can weaken its health, while too much may cause a stress response.

Ideal: Full sun
FAQ
What are the sunlight requirements for a Be still tree?

The Be still tree requires full sun, meaning it needs above 6 hours of sunlight daily to thrive. It's vital to observe how sunlight moves through your garden to ensure your Be still tree gets a perfect balance of light and shade. This balance is crucial for its health and happiness. The tree has evolved in its native habitat to flourish under abundant solar light, and both too little and too much light can adversely affect its health.

How can artificial lighting be used for Be still trees?

Indoor Be still trees require adequate lighting to ensure optimal growth, especially when natural sunlight is insufficient, such as in winter or in less sunny spaces. Artificial lights, such as LED lights that provide specific wavelengths of light needed by plants, are a vital solution. For full sun plants, 30-50W/sq ft of artificial light is recommended, 20-30W/sq ft for partial sun plants, and 10-20W/sq ft for full shade plants. The light source should be placed 12-36 inches above the plant to mimic natural sunlight, and most plants need 8-12 hours of light per day.

What are the symptoms of light deficiency in Be still trees?

Be still trees show several symptoms when exposed to insufficient lighting, including smaller new leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, lighter-colored new leaves, and chlorosis. Excessive sunlight can cause sunscald, leaf curling, wilting, leaf scorching, indicating too much exposure. These symptoms help in identifying whether the plant is receiving too little or too much light.

What solutions can be applied to solve light-related issues in Be still trees?

To address light-related issues in Be still trees, gradually increase sunlight exposure to ensure the plant receives at least 6 hours of direct sunlight daily. For indoor plants, using a south-facing window or artificial light like a desk or ceiling lamp for at least 8 hours daily can help. For outdoor plants, moving them gradually to sunnier spots can prevent sunburn. If sunlight is obstructed by elements like trees, consider pruning to allow sunlight to reach the plants. For smaller plants, transplantation during the dormant period to a location with ample sunlight and good drainage could be beneficial.

🌡️ Temperature 20–35°C

Be still tree is native to temperate environments where temperatures range from 68 to 95 °F (20 to 35 ℃). Adjustments may be necessary during cooler seasons to maintain the optimal temperature for be still tree.
