Best Terrarium Plants: Top Picks for Your Open or Closed Terrarium Setup

Q: Do I need a lot of direct sunlight per day to start a balcony garden?
A: No. While cherry tomatoes need 6-8 hours of direct sunlight per day, leafy greens and herbs like parsley or chive thrive in partial shade. Simply choose the right plants for your specific amount of sun.
Q: Can I use standard garden soil in my balcony pots?
A: No. Standard garden soil is too heavy and compacts easily. Always use a high-quality, well-draining potting soil mixed with peat moss and compost for your container garden.
Q: How often should I be watering my plants on a balcony or rooftop?
A: Check daily. Stick your finger an inch into the soil; if it is dry, it is time to water. Container plants dry out quickly, so ensure pots have holes in the bottom and consider self-watering pots for convenience.
Q: Why are my shade-loving plants losing their variegated leaves?
A: If a plant with unique foliage or variegated leaves (like a Hosta) is planted in deep, absolute shade, it may revert to producing solid dark green leaves to maximize its chlorophyll production. Moving it to an area with light shade or dappled morning light often restores the vibrant array of color.
Q: What does it mean when a plant is "drought tolerant"?
A: Drought tolerant plants, like Dusty Miller with its thick silver foliage, have adapted to survive long periods with very little water. However, "tolerant" does not mean "immune." They still grow best with occasional deep watering, especially when planted in containers that tend to dry out rapidly.
Q: Can I mix these outdoor foliage plants into my existing herb garden?
A: Absolutely! Many gardeners slip a colorful container of Coleus or Sweet Potato Vine right next to their raised beds or herb garden to add a splash of non-edible color to the functional space. Just ensure the light requirements match the surrounding plants.
Q: Do I really need a grow light, or is my sunny window enough to grow plants indoors?
A window is fine for a low-light houseplant. However, to grow vegetables indoors, start a robust indoor herb garden, or grow any edible plants to grow successfully, you absolutely need a grow light. Windows filter usable light, and winter daylight is too short during the growing season. LED lights are the best tip to give your indoor garden a great start.
Q: My indoor vegetable seedling keeps falling over and dying at the base. What am I doing wrong?
This is "damping off," a fungal disease from overly wet potting soil and poor airflow. To prevent this, ensure your pot has a functional drainage hole, never let the seedling sit in water, and remove humidity domes the moment seeds sprout. A gentle fan nearby also helps.
Q: I live in a very small space. What are the best plants to grow that won't take over my apartment?
For a small garden, focus on vertical growth. An indoor herb garden using a windowsill herb garden planter is perfect. For edible plants, try growing micro varieties of vegetables or leafy greens in a small indoor container. Try easy to grow at home trailing plants like Pothos that hang from the ceiling to save space to grow.

FAQs
Q: Can succulents thrive in terrariums?
A: Succulents can thrive in open terrariums but are generally not ideal for closed terrariums. Open terrariums provide the airflow and drier environment that succulents need to prevent root rot and overhydration. Closed terrariums, with their high humidity and limited ventilation, create conditions that are too moist for most succulents to survive.
Q: Can I use cuttings to start a terrarium?
Absolutely! Using cuttings to start a terrarium is one of the best ways to grow plants in a small, contained environment. Many plants, like Pothos and Peperomia, are great for this because they root easily. You can simply snip off a healthy stem, place it in water for a while, and then add it to your terrarium once it's rooted. It’s a fun, cost-effective way to propagate your favorite houseplants, and it helps your terrarium flourish without having to buy a new plant every time!
Q: Can I grow cactus in a terrarium?
Cacti can be a bit tricky when it comes to terrariums because they prefer dry, well-ventilated spaces, which can be tough to achieve in a closed container. While they thrive in open terrariums with lots of light and airflow, you’ll want to be mindful of humidity. Too much moisture in the air can cause them to rot. If you love the look of miniature cacti, just be sure to pick a terrarium with plenty of ventilation and avoid over-watering.
