Do you have a fondness for greenery and a green thumb to match? The Boston fern could be the perfect companion for you! Easily one of the most beautiful and lush houseplants, the Boston fern has graced the homes of avid plant lovers for years. Although these plants are relatively easy to care for, mastering the art of Boston fern care requires dedication and a good understanding of the basic requirements for optimal health. Read on to learn all you need to know about Boston fern care.

Light and Temperature Requirements

Caring for a Boston fern is art, but specific requirements must be met to ensure a healthy and thriving plant. Regarding light and temperature, Boston ferns tend to thrive in bright indirect sunlight but not direct sunlight, which could cause the plant to become stressed out and eventually die.

The ideal temperature for a Boston fern is between 70 and 80 degrees Fahrenheit, which makes them perfect for indoor spaces in moderate climates. To ensure your fern has enough light, you can move it around your home from room to room or install an artificial light source if you do not have enough natural light in the area. During cold winter, it is best to keep your fern away from drafty, cold windowsills and avoid air conditioning, if possible.

Watering Requirements

Boston ferns require consistent moisture to stay healthy and lush. Ideally, it would be best if you watered your Boston fern at least once a week, but depending on your home’s humidity levels, you may need to water it more often. It’s best to check the soil before you water—if the top inch of soil is dry, it’s time to water.

When it comes to your Boston fern’s water, you should use distilled or lukewarm water to avoid any potential shock from the chlorine in tap water. Additionally, avoid overwatering, as this can cause root rot and other issues. To ensure the water drains out of the pot, you should slowly and thoroughly water your Boston fern.

Finally, Boston ferns highly benefit from a humidity tray. You can make a humidity tray by placing the pot on a few stones filled with distilled water. Make sure to change out the water regularly to avoid any stagnant water or mosquito issues. So, while it may seem like a lot of effort, following these simple tips can help make sure your Boston fern stays healthy and happy!

Fertilizer Requirements

Using the correct type of fertilizer is essential, as the wrong type could potentially harm the fern. A regular liquid fertilizer or a slow-release fertilizer formulated explicitly for Boston ferns is best. It is advisable to fertilize your Boston ferns every two weeks during the spring and summer growing seasons and every four weeks in the fall and winter.

When fertilizing your Boston ferns, use a water-soluble fertilizer and dilute it to 1/4 the strength recommended on the package. This will help prevent over-fertilizing and burning the fern. A good rule of thumb is to use half the recommended fertilizer on your Boston fern.

It is also essential to use the right amount of fertilizer. Applying too much fertilizer can cause excessive leaf growth and yellowing, while too little can cause your fern to be undernourished and deplete the soil of its plant nutrients.

Finally, give your Boston ferns a little extra fertilizer after repotting them. This will help the ferns to settle into their new home and get established.

Potting and Repotting

The first step to potting your Boston Fern is choosing suitable soil. Look for one that is well-draining and contains peat moss, compost, bark, and other organic material to provide structure and nutrients. Stay away from the soil with a high concentration of fertilizers, as this can cause root burn and other issues.

Once you’ve chosen the suitable soil, it’s time to add it to your pot. To ensure your Fern is rooted correctly, place the soil at least two inches below the pot’s rim. As a rule of thumb, you should leave an inch or two of space between the Fern and the edge of the pot for some extra room to grow.

Regarding repotting, the process is similar to potting, with a few key differences. First, it’s essential to ensure your pot isn’t too deep, as this can cause issues with drainage. Also, it’s best to choose a pot that’s only one or two inches larger than your current pot. This will ensure that the soil doesn’t dry out too quickly.

Remove the plant from its old pot when ready to report your Boston Fern. Be sure to support its root system as you do so. Once removed, gently shake off any excess soil and inspect the roots for any signs of disease.

Next, transfer your plant to its new pot and fill it with soil. Tamp down the soil and spread it evenly before placing your Boston Fern in its new home. After that, water your Fern and place it in a spot with indirect sunlight.


Before you begin, investing in a pair of sharp scissors or pruning shears is essential. These will help you get clean cuts, making the pruning process easier. You should also ensure to sterilize any tools you use to avoid transferring diseases.

When pruning, removing dead fronds that look pale and brown is essential. These should be cut off at their base to ensure no new growth will occur. Additionally, you should remove any yellowed fronds that look unhealthy. This encourages more robust growth by redirecting energy away from the dying fronds and toward the plant’s healthy ones.

It’s also essential to space pruning out. Over-pruning can be detrimental to the well-being of your fern, so you should aim only to prune the dead fronds every couple of weeks. Doing so will keep the new growth healthy and give the plant enough time to recover from each pruning session.

Last but not least, you should never remove more than ⅓ of the foliage at any time. This will prevent the plant from becoming stressed and ensure that your Boston fern remains in top condition.

Common Pests and Diseases

Common pests in the Boston fern family include scale insects, mealybugs, spider mites, and aphids. These pests can damage the foliage and weaken the plant, so it’s essential to take preventative measures.

You can ward off pests by keeping the leaves clean and debris-free. Regularly washing the leaves with a mix of water and dish soap can help, as can wiping them with a damp cloth. Invest in a suitable insecticide and spray at the first sign of infestation. If the insect infestation is wrong, you may need to discard the fern and start again.

As for diseases, be sure to watch out for root rot. Root rot occurs when the soil is saturated with too much moisture. To prevent this, keep the soil slightly damp but never soggy. Using well-draining soil with plenty of organic matter is also a good idea.

Another common ailment is fungal leaf spot. This is caused by a fungal infection that spreads to the leaves, causing yellow spots and wilting. To prevent this, keep the plant away from humid areas and avoid over-watering. It’s also essential to space Boston ferns to allow for air circulation.

Regularly inspecting your Boston fern and taking the necessary steps to prevent pests and diseases can ensure it stays healthy and grows for many years to come.


Boston ferns are an easy and rewarding way to give a natural boost of beauty to any indoor or outdoor environment.

It may take a little trial and error to find out what is best for your specific fern, but with these tips, you’re well on mastering the art of Boston fern care. With a little TLC, your fern will have a long, healthy life and provide a beautiful, natural touch to any corner of your home or garden.
