Hey there, fellow plant lovers! I'm a supplier of haworthia plants, and I've seen firsthand how these little succulents can bring a touch of nature and beauty into any space. One of the trendy ways to grow haworthias is in a terrarium, which creates a mini - ecosystem for these plants. In this blog, I'll share with you the requirements for growing haworthia plants in a terrarium.
1. Choosing the Right Terrarium
First things first, you need to pick the right terrarium. There are two main types: open and closed. An open terrarium is great for haworthias because they're succulents that need good air circulation. Closed terrariums tend to trap moisture, which can lead to root rot in haworthias.
When choosing the size, don't go too big or too small. A medium - sized terrarium, around 6 - 12 inches in diameter, is usually a good fit. This gives the haworthia enough room to grow but also maintains a stable micro - environment. You can find all sorts of terrariums at your local gardening store or online. Just make sure the container has a clear lid if it comes with one. This allows sunlight to reach the plants and also makes it easy for you to monitor the haworthia's growth.
2. Selecting the Haworthia Species
There are many different species of haworthia, and some are better suited for terrariums than others. For example, Haworthia Arachnoidea 'joubertii' is a great choice. It has a unique appearance with white, hair - like filaments on its leaves, and it doesn't grow too large, making it perfect for a terrarium.
Another option is the Haworthia 'Royal Albert' Plant. It has beautiful, compact rosettes of leaves that add a lot of visual interest to the terrarium. And then there's the Haworthiopsis Reinwardtii, which is quite hardy and can tolerate a bit of neglect, making it a great beginner - friendly option.
When selecting your haworthia, look for healthy plants with no signs of pests or diseases. The leaves should be firm and plump, not wilted or discolored.
3. Soil Requirements
Haworthias need well - draining soil. In a terrarium, this is even more important because excess moisture can't escape as easily as it would in an open pot. You can use a commercial cactus or succulent soil mix. These mixes are usually made with ingredients like perlite, pumice, and sand, which help with drainage.
If you want to make your own soil mix, you can combine equal parts of potting soil, perlite, and coarse sand. This creates a light and airy soil that allows the haworthia's roots to breathe. Before adding the soil to the terrarium, make sure it's clean and free of any debris. You can even bake the soil in the oven at a low temperature for about 30 minutes to kill any potential pests or pathogens.
4. Lighting Conditions
Haworthias love bright, indirect light. In a terrarium, you need to find the right balance. Direct sunlight can be too intense and may cause the terrarium to overheat, which can harm the haworthia. Place the terrarium near a window that gets plenty of light but is shaded by a curtain or a tree outside.
If you don't have a suitable window, you can also use artificial grow lights. LED grow lights are a popular choice because they're energy - efficient and can be adjusted to provide the right spectrum of light for the haworthia. Keep the lights on for about 10 - 12 hours a day to mimic natural daylight.
5. Watering Needs
One of the biggest mistakes people make when growing haworthias in a terrarium is over - watering. These succulents are adapted to dry conditions, so they don't need a lot of water. Water the haworthia only when the soil is completely dry. You can check the soil moisture by sticking your finger about an inch into the soil. If it feels dry, it's time to water.
When watering, use a small watering can or a spray bottle to gently moisten the soil. Avoid getting water on the leaves, as this can lead to rot. In a terrarium, the water evaporation rate is slower than in an open pot, so you may only need to water once every 2 - 3 weeks.
6. Temperature and Humidity
Haworthias prefer temperatures between 65°F and 80°F (18°C - 27°C). They can tolerate slightly cooler temperatures at night, but try to keep the terrarium away from cold drafts or extreme heat sources like radiators.
As for humidity, haworthias are used to low - humidity environments. In a terrarium, aim for a humidity level of around 30% - 40%. If the humidity gets too high, you can open the lid of the terrarium for a few hours each day to let some moisture escape.
7. Fertilizing
Haworthias don't need a lot of fertilizer. You can fertilize them once or twice a year during the growing season (spring and summer). Use a diluted, balanced liquid fertilizer for succulents. Follow the instructions on the fertilizer package for the correct dilution ratio.
Over - fertilizing can cause the haworthia to grow too quickly, which can make it weak and more prone to diseases. So, it's better to err on the side of under - fertilizing.
8. Maintenance and Pruning
Regular maintenance is important for the health of your haworthia in a terrarium. Check the plant regularly for any signs of pests, such as aphids or mealybugs. If you see any pests, you can use a cotton swab dipped in rubbing alcohol to remove them.
Pruning is also a good idea. Remove any dead or damaged leaves to keep the plant looking neat and to prevent the spread of diseases. You can use a clean pair of scissors or pruning shears to make clean cuts.
9. Monitoring and Troubleshooting
Keep an eye on your haworthia's growth. If you notice that the leaves are turning yellow or brown, it could be a sign of over - watering, under - watering, or too much sunlight. Adjust the watering schedule or move the terrarium to a different location.
If the plant seems to be growing slowly or not at all, it could be due to a lack of nutrients or improper lighting. Try fertilizing it or adjusting the light source.
In conclusion, growing haworthia plants in a terrarium can be a fun and rewarding experience. By following these requirements, you can create a beautiful and healthy mini - ecosystem for your haworthias.
