Out of the roughly 12,000 fern species worldwide, the vast majority call tropical rainforests home. Only about a hundred or so are native to Central Europe, which might make you wonder: can you actually grow these lush beauties in containers on a balcony?
Choosing the Right Variety
Ferns come in all shapes and sizes, and let’s be honest—a massive tree fern isn’t going to be happy in a small pot on your patio. However, there are plenty of smaller varieties that thrive in containers and don’t need a ton of elbow room. Some of my favorite picks for balcony gardening include:
- Common Polypody (Tüpfelfarn)
- Rustyback Fern (Schriftfarn)
- Maidenhair Fern (Frauenhaarfarn)
- Hart’s-tongue Fern (Hirschzungenfarn)

Before you head to the nursery, take a look at which way your balcony faces. If you have a south-facing balcony that gets blasted with sun all day, ferns probably aren’t the best choice for you. These plants are shade-lovers through and through. They thrive in full to partial shade and will quickly scorch if left in direct sunlight.
Besides shade, ferns also appreciate a bit of shelter. They aren’t big fans of drafty spots, so if your balcony gets windy, try tucking them closer to the house wall for a little extra protection.
Planting and Care Tips
To keep your ferns looking lush and green, you’ll want to start with the right soil. Look for a mix that is:
- Rich in organic matter (humus)
- Moderately nutrient-dense
- Slightly acidic (low pH)
When it comes to maintenance, the golden rule is: don’t let them dry out! Ferns love consistent moisture. Pro tip: use rainwater or let your tap water sit out for a bit before watering. For feeding, you can use a liquid fertilizer every two to four weeks during the growing season, or keep it simple with some slow-release fertilizer sticks.
