Ferns: Are They Really So Hard to Grow?
Have you ever found yourself grabbing a stunning silver blue fern or a bushy Boston fern at the store, only to put it back when you remember how many times you’ve accidentally killed your previous ferns? We’ve all been there. I can’t count on the fingers of both hands how many ferns I’ve brought home only to watch them wither away. However, after some trials and errors, I’ve figured out how to grow them successfully and even discovered which varieties are hardy and thrive on neglect. Here are my best tips and findings to help you care for your ferns. Watering You might have heard the famous advice: “Keep moist but not waterlogged.” But what does that really mean? Essentially, it means that when you touch the potting mix, it shouldn’t feel dry, but it also shouldn’t be muddy. Think of it as watering more often with small amounts of water rather than a lot of water once a week. Here are a few things to consider: Planter Type: Avoid terracotta pots as they absorb moisture and dry out the soil faster. Unless you enjoy daily plant care, opt for a plastic nursery pot placed inside a decorative planter. This setup helps maintain moisture levels. Drainage: Ensure your planter has proper drainage. If you overwater your fern, you’ll notice water sitting at the bottom of the planter. Ferns dislike “wet feet” (unlike some plants like Alocasia) and can develop root rot if left in standing water. Water Quality: Use distilled or filtered water, or even rainwater if possible. This helps avoid any issues with the chemicals present in tap water. Soil One crucial step for fern care is to repot your fern as soon as you bring it home. Most store-bought ferns are pot-bound, and upgrading their soil can make a big difference. Here’s how to handle it: Fern Potting Mix 5L Pre-Repotting Soak: Generously water the plant and let it soak to loosen the root ball, making repotting easier and ensuring that the roots are more pliable, reducing the risk of damage during the repotting process. Soil Choice: Since ferns like to stay moist, a good potting mix would be coco coir with perlite and some peat to lower pH. Coco coir is known to retain moisture for longer periods, making it an excellent choice for ferns. A quick Google search based on the specific fern you have will guide you to the best soil type. Light While ferns don’t like direct sunlight, they still need a good amount of light to thrive. Please don’t place your ferns in dark corners or windowless bathrooms. The more light they get (without direct sunlight), the better they’ll grow. Humidity If your bathroom happens to have a window, it will be a great spot for your fern as they love higher humidity. Otherwise, speaking from experience, I had no problems with ferns in my Berlin apartment with average humidity. Recommended Ferns for Beginners For those new to growing ferns, I recommend starting with these varieties: Bird’s Nest Fern: Hardy fern that doesn’t mind if you forget to water it occasionally. It’s broad, arching fronds can add a lush, tropical feel to any indoor space, making it an ideal houseplant for those looking to bring a touch of greenery into their home. This fern thrives in indirect light and can tolerate low-light conditions, making it perfect for rooms without much natural sunlight. Additionally, it can help purify the air, contributing to a healthier living environment. Just make sure to keep its soil slightly moist and avoid letting water sit in the crown, as this can cause rot. Crocodile Fern: Super easy to grow and possibly the hardest fern to kill—as long as you don’t overwater it! It tolerates drying out between waterings quite well. This unique fern, with its rugged, crocodile-like textured leaves, makes for an attractive indoor plant. Additionally, it thrives in indirect light and is exceptionally adaptable to various environments. Whether you’re a beginner or an experienced gardener, the Crocodile Fern is a delightful addition to your plant collection due to its resilience and low-maintenance nature. Boston Fern: This guy is definitely next level, but if you repot it and keep it far away from touch with enough space around it in a well-lit spot, it will grow like crazy! Additionally, it’s important to keep the soil consistently moist but not waterlogged, as Boston Ferns thrive in high humidity. Regular misting and placing a humidifier nearby can also aid its growth. Don’t forget to feed it with a balanced, water-soluble fertilizer every month during the growing season to ensure it receives all the necessary nutrients. With just a bit of care and attention, you’ll have a lush, thriving fern that adds a touch of natural beauty to any space. Asparagus Fern: Probably my favorite! This one definitely prefers regular watering and doesn’t like to be dry, but in my experience, it won’t die quickly if you ever water it a day late. Its delicate, feathery foliage adds a touch of elegance to any space, and it’s relatively forgiving when it comes to lighting conditions. Although it thrives in bright, indirect light, it can tolerate lower light levels, making it a versatile choice for various rooms in your home. Growing it near humidifier will help maintain its lush appearance and prevent the leaves from drying out, which is particularly helpful if you live in a dry climate or during colder months when indoor heating can reduce humidity levels. By following these tips, you can turn your home into a fern-friendly haven. Happy growing!Monika Like what you read? Why not sign up for our newsletter and never miss a blog post?
