1. Introduction: Why is it difficult to grow succulents indoors?
Succulents are often grown outdoors, but recently, more and more people are looking to grow them indoors. However, why is it difficult to grow succulents indoors? The reasons can be summarized into the following four main points:
① Insufficient sunlight
② Proper ventilation
③ Watering
④ Temperature control
By understanding these challenges and carefully following the advice to address them, it is possible to enjoy growing succulents indoors.
2. Main challenges in growing succulents indoors
There are several challenges to growing succulents indoors.
(1) Insufficient sunlight: Indoor environments have limited natural light, making it difficult to provide the adequate light succulents need. A lack of sunlight can lead to etiolation, where the stems stretch out.
(2) Proper ventilation: Indoor spaces tend to have poor air circulation. Poor ventilation can lead to high humidity, which causes pests, diseases, and root rot.
(3) Watering: Succulents have evolved to thrive in harsh environments, so overwatering can cause root rot. This makes proper moisture management difficult indoors.
(4) Temperature control: Indoor environments have less temperature fluctuation, making seasonal temperature adjustments difficult. Succulents, in particular, need cool conditions in summer and warm conditions in winter, requiring careful temperature management.
(1) Insufficient sunlight: Limited light sources indoors
Succulents naturally grow in environments with abundant sunlight, so insufficient sunlight is a problem for indoor cultivation. While placing them near a window is common, it can still be difficult to ensure sufficient light intensity.
In particular, insufficient light can significantly affect their growth, leading to poor coloration or stretching. Additionally, direct summer sunlight can cause high-temperature damage, so caution is needed.
Therefore, we recommend using supplemental lighting that allows you to adjust the light intensity and duration. With such measures, you can compensate for insufficient sunlight and grow succulents healthily indoors.
(2) Proper ventilation: Air circulation is essential for healthy growth
When growing succulents indoors, proper ventilation is crucial. Succulents are generally tolerant of dry conditions, but high humidity can cause them to rot, so air circulation is essential.
Placing them in a well-ventilated spot, opening windows for airing, or using a circulator or small fan to create airflow can reduce humidity and prevent mold and mildew. However, too much direct strong wind can dry out the leaves, so aim for moderate ventilation.
These measures can create a healthy environment for succulents to grow.
(3) Watering: Difficult to manage moisture properly
Watering succulents indoors is not straightforward. Different types of succulents have varying needs for moisture and watering frequency, so there's no single "correct" amount of water to give. Furthermore, indoor environments tend to have high humidity, and overwatering can lead to root rot.
A common watering tip is to wait until the soil is completely dry, then water thoroughly. However, this varies depending on the plant species and season, so continuous observation is crucial.
To determine if the soil is dry, you can insert your finger into the soil; if your fingertip feels moist, no water is needed yet, but if it's dry, it's time to water.
While managing moisture for succulents may seem difficult, it's important to nurture them with care, appreciating the vitality each plant possesses.
(4) Temperature control: Effects of indoor temperature changes
Succulents are extremely sensitive to environmental temperature changes, and this is the biggest challenge in indoor cultivation. In nature, temperatures vary significantly between day and night, but indoors, temperatures tend to remain constant. This can hinder the growth of succulents.
Succulents require a diurnal temperature range; without it, they cannot perform photosynthesis adequately and will struggle to grow healthily. Particularly in winter, if indoor heating makes the room too warm, succulents may not be able to "hibernate" and can experience stress.
Therefore, careful temperature management is essential indoors. Various measures are required, such as maintaining appropriate temperatures for each season and using heating sparingly.
3. Specific advice to solve the challenges
Here is some advice to address the challenges of sunlight, ventilation, watering, and temperature control, which are often considered difficult when growing succulents indoors.
(1) Sunlight issues : Insufficient indoor sunlight can be resolved with supplemental lighting. Choose light intensity and color temperature appropriate for your succulents, and use it especially during winter when daylight hours are short.
(2) Ventilation issues : Using a fan improves ventilation and provides sufficient oxygen to the plants. However, be careful not to let the fan blow directly on the plants, as this can dry them out too much.
(3) Watering issues : Succulents prefer dry conditions, so check the soil's dryness by touching it with your finger. Check not only the surface but also 1-2 cm deep.
(4) Temperature control issues : Indoor temperature changes require seasonal measures. For example, in winter, keep plants away from heaters, and in summer, avoid placing them where they receive direct drafts from air conditioners.
(1) Adjustable light source: Utilizing supplemental lighting
First, succulents require abundant light, but natural light alone may be insufficient indoors. Therefore, using supplemental lighting is crucial.
LEDs and fluorescent lights are recommended for supplemental lighting. They are energy-efficient and suitable for long-term use. LED lights, in particular, can control light wavelengths, efficiently supplying the red and blue light necessary for succulents.
The placement of the light is also important. Illuminating the plants from above at a 45-degree angle can mimic natural light conditions. These efforts can help you succeed in growing succulents indoors.
(2) Efforts to improve ventilation: Using fans and timing window openings
For healthy succulent growth, proper ventilation is necessary in addition to sunlight. Ventilation helps dry the entire plant, preventing mold, mites, and rot.
When growing indoors, one method is to frequently open and close windows to improve ventilation. However, direct drafts can stress the plants, so be mindful of the window's position relative to the plants. Besides opening windows, using a fan or circulator is also recommended. These fans can be positioned to circulate air throughout the plants without blowing directly on them.
However, in winter, be careful not to let them dry out too much. Remember to provide adequate moisture to maintain humidity.
With the above efforts, it is possible to grow healthy succulents indoors.
(3) Watering tips: How to gauge soil dryness
Watering, often considered the most challenging aspect of growing succulents indoors, actually varies depending on their growth type. To water appropriately, it's crucial to first know which growth type your succulent belongs to.
For example, for spring/summer growing succulents, it's recommended to reduce watering during summer temperatures above 30 degrees Celsius and winter temperatures below 10 degrees Celsius. Conversely, for summer growing succulents, reduce watering in winter when temperatures are below 10 degrees Celsius, and for winter growing succulents, reduce watering in summer when temperatures are above 30 degrees Celsius.
It's also important to assess soil dryness by touch rather than relying solely on appearance. Water when the soil is completely dry, and similarly, water when the leaves appear shriveled. By keeping these points in mind, watering succulents won't be difficult.
(4) Temperature control advice: Seasonal measures, etc.
Succulents that can be grown indoors are sensitive to temperature changes. Winter, in particular, requires caution, and some species (e.g., Haworthia) are recommended to be moved indoors when night temperatures drop below 5 degrees Celsius.
On the other hand, with proper management, some species like Echeveria and Sedum can overwinter outdoors even in cold regions. In such cases, taking measures to protect them from cold winds and reducing watering can enhance their cold hardiness.
Specific measures include:
