How To Make A Boston Fern Go Dormant

To make a Boston fern go dormant, you need to gradually reduce its water, light, and temperature over several weeks in late autumn.
 
This process mimics the natural seasonal shift the fern would experience in the wild.
 
By learning how to make a Boston fern go dormant, you help the plant conserve energy and survive the winter with minimal stress.
 
Many gardeners find that making a Boston fern go dormant is the secret to keeping the plant lush and full year after year.
 
In this post, we will cover exactly how to make a Boston fern go dormant, why this rest period matters, and how to care for it during its winter sleep.
 
Let’s walk through the steps on how to make a Boston fern go dormant so your fern stays healthy through every season.
 

How to Make a Boston Fern Go Dormant

Making a Boston fern go dormant is a straightforward process that requires patience and consistency.
 
Here is the step-by-step method to encourage your fern to enter its resting phase.
 

1. Start Reducing Water Gradually

The first step in how to make a Boston fern go dormant is to cut back on watering in early autumn.
 
Instead of keeping the soil consistently moist, let it dry out slightly between waterings.
 
This signals to the fern that the growing season is ending.
 
Over the next few weeks, reduce watering even more until the soil stays on the drier side.
 
This gradual reduction is essential when learning how to make a Boston fern go dormant without shocking the plant.
 

2. Move It to a Cooler Location

Temperature plays a major role in how to make a Boston fern go dormant successfully.
 
Boston ferns thrive in temperatures between 60 and 75 degrees Fahrenheit during active growth.
 
To trigger dormancy, move your fern to a spot where temperatures stay between 50 and 55 degrees Fahrenheit.
 
A basement, unheated garage, or cool room works perfectly for making a Boston fern go dormant.
 
Just avoid freezing temperatures as they can damage the fronds and ruin your efforts on how to make a Boston fern go dormant.
 

3. Cut Back on Light Exposure

Another important step in how to make a Boston fern go dormant is reducing light levels.
 
Boston ferns need bright, indirect light during the growing season.
 
But when you are making a Boston fern go dormant, move it to a spot with low to no direct light.
 
A dim corner or a room with only a north-facing window works well for this purpose.
 
This low-light condition tells the fern it is time to rest and reinforces how to make a Boston fern go dormant effectively.
 

4. Stop Fertilizing Completely

Fertilizer encourages new growth, which is the opposite of what you want when making a Boston fern go dormant.
 
Stop feeding your fern about six weeks before you plan to induce dormancy.
 
This helps the plant slow down naturally and prepare for its rest.
 
When you are focused on how to make a Boston fern go dormant, no fertilizer is needed at all during the process.
 

5. Prune Back the Fronds

Before making a Boston fern go dormant, trim away any dead or yellowing fronds.
 
This tidies up the plant and reduces the amount of foliage it needs to support.
 
You can also cut back healthy fronds by about one-third to conserve energy.
 
Pruning is a helpful step in how to make a Boston fern go dormant because it directs energy to the roots.
 

Why You Should Learn How to Make a Boston Fern Go Dormant

You might wonder why making a Boston fern go dormant is beneficial in the first place.
 
Here are the main reasons this process helps your plant thrive.
 

1. It Mimics Natural Seasonal Cycles

In the wild, Boston ferns experience cooler temperatures and shorter days in winter.
 
They naturally slow down their growth during this time.
 
Making a Boston fern go dormant replicates this natural cycle and keeps your fern in sync with its biology.
 
Your fern gets the rest it needs to come back stronger in spring.
 

2. It Prevents Weak and Leggy Growth

If you do not make a Boston fern go dormant, it may keep trying to grow through winter.
 
But without enough light and warmth, that growth will be weak and leggy.
 
Making a Boston fern go dormant prevents this poor-quality growth from happening.
 
The plant stays compact and healthy instead of stretching for light.
 

3. It Reduces Winter Watering and Maintenance

During dormancy, Boston ferns need much less water and attention.
 
This makes winter care much easier for you as a plant owner.
 
Making a Boston fern go dormant means you water only every two to three weeks.
 
You will have fewer chores and a happier plant all winter long.
 

Common Mistakes When Making a Boston Fern Go Dormant

Even with good intentions, it is easy to make errors when learning how to make a Boston fern go dormant.
 
Avoid these common pitfalls for the best results.
 

1. Reducing Water Too Quickly

One mistake is cutting water abruptly instead of gradually.
 
This can shock the fern and cause leaf drop or stress.
 
Remember that how to make a Boston fern go dormant involves a slow transition, not a sudden change.
 

2. Keeping the Fern in a Warm Room

Another mistake is leaving the fern in a warm, heated room during winter.
 
If the temperature stays above 60 degrees, the fern will not enter full dormancy.
 
Part of how to make a Boston fern go dormant is providing that cool 50 to 55 degree zone.
 

3. Watering During Dormancy as If It Is Growing

Some people continue watering their fern on the same schedule as summer.
 
This leads to waterlogged soil and root rot.
 
When you understand how to make a Boston fern go dormant, you know that less water is critical.
 

4. Fertilizing During the Rest Period

Applying fertilizer while the fern is dormant can force unwanted new growth.
 
This new growth will be weak because the plant does not have enough light or warmth.
 
A key part of how to make a Boston fern go dormant is withholding all fertilizer until spring.
 

So, How Do You Make a Boston Fern Go Dormant?

To make a Boston fern go dormant, you gradually reduce water, light, and temperature over several weeks in late autumn.
