Tips for Saving Geraniums and Ferns Overwinter

If you’ve been following along for a minute, you know we built a greenhouse in the spring of 2022, and saving money on plants is one of the reasons for building it.

First, the greenhouse is not heated and living in zone 7B; our winters are usually mild. However, it would be best if you were prepared for unexpected cold weather and prolonged periods of freezing weather.

What If I Don’t Have A Greenhouse? Can I Save My Geraniums?

If you don’t have a greenhouse, you can still save your plants over winter. Here are some options that will work with all the suggestions below.

• Basement
• Storage Building
• Crawl Space
• Root Cellar
• Garage
• Unheated Closet
• Build a wooden box against the house or storage shed to place the plant.

If you get creative, I’m sure you can find a space to store your plants overwinter, and the savings next Spring will be worth the effort.

To determine what planting zone you are located in, go to Garden.Org.

These tips work for any space, such as an enclosed porch, basement, or storage building.

In addition, you will find so much conflicting information online, and some techniques will work in certain zones and will not work in others. That’s why I spoke with friends with personal experience for their advice.

Agreed Upon Tips to Overwinter

Although there is a lot of conflicting information, here are a few things that are agreed upon.

• Allow plants to become dormant during the winter
• Remove dead and diseased stems and leaves before bringing inside
• Water only when the soil is completely dry – over watering can result in root rot or mold.
• Keep in a cool place with temperatures ranging from 60-40 degrees
• Avoid direct sunlight as filtered sunlight is best. However, ferns can be placed in a cool dark space such as a basement as well.
• Don’t over heat and if using a space heater don’t allow air to blow directly onto the plants
• Keep an eye on the plants and remove any new growth during the winter
• Also, remove any dead or diseased stems or leaves immediately

Tips to Overwintering of Geraniums

Geraniums are a favorite flowering plant because they bloom from Spring through Fall. If you care for them properly, they will be full of blooms all season long. You can see how to ensure beautiful, continuous blooms.

I have decided to try two techniques for the overwintering of geraniums. Since this is the first year for the mother plant, I want to keep it over the winter by cutting back the excess stems and allowing it to become dormant.

Transfer the plant into a clean container with fresh potting soil, remove dead or diseased stems and trim back excess foliage.

Propagate Geraniums

First, as you are cutting the plant back to overwinter, you can propagate new plants from the cuttings.

You will want to place a clean container. If you use recycled containers, wash them thoroughly and allow them to dry before planting.

Cut stems from the mother plant just above a leaf joint using sharp pruning shears.

Remove all but a couple of leaves at the top of the stem. Place in your dry containers and fill with seed compost. Water thoroughly and place in filtered sunlight to ensure rooting.

Remember to keep new growth pinched off over the winter months.

Overwinter Ferns successfully

Ferns are another expensive purchase every spring; therefore, I overwinter ferns also.

There are a variety of opinions on saving ferns. You can bring them inside as a houseplant. However, they may or may not do well back outside next spring. In addition, you can place it in a dark area, such as a basement, that stays above 40 degrees over winter.

A friend suggests trimming any dead stems with pruning shears and bringing them inside a cool spot with filtered light, such as the greenhouse. Only water the ferns approx. once a month or when the soil is completely dried out. This is the method I plan to use on some of the ferns this year.

In addition, I plan to try a second tip for some of the ferns. Another recommendation is to trim the ferns back to approx. 1/3 their size. This involved cutting around the edges of the plant until there were only stems standing up in the center of the plant.

Be aware that your fern will not look lush and green during its dormant state. This is perfectly normal.

Be Prepared for Freezing Temperatures When Overwintering of Geraniums and Ferns

With milder temperatures here in the south, Geraniums and Ferns should do well over winter. However, you must be prepared should extreme cold temperatures hit your region.

The DIY potting bench is being prepared should that occur this winter. A piece of insulation fiberboard has been placed on the floor, and all the plants can be placed on the board.

In addition, horticultural bubble wrap has been purchased to drape over the potting table and can be tucked in around the plants to protect further.

The bubble wrap can also be placed around the individual containers if necessary. It can also be used around outdoor containers to prevent the root ball from freezing. This will come in handy for those large containers you cannot bring inside.

Important Note: On warm days, you will want to remove the bubble wrap and space your plant apart. Many plants will develop mold without proper airflow around them.

A simple space heater is also available for extended days of clouds and below-freezing temperatures.

UPDATE: Overwinter Success

I had great success saving geraniums and ferns overwintered using these techniques. Your success will most likely depend on your zone.

I also found that trying to overwinter more delicate plants was a wasted effort in my zone.

However, the techniques for overwintering of geraniums and overwinter ferns worked well and have saved me money each Spring. These suggestions have definitely been worthwhile.

Other Preparations for Spring Blooms

In addition to overwintering plants, I’ve also been planning for more spring blooms. As I’ve removed spent plants, I’ve added spring bulbs to the garden.

Now is the perfect time for planting spring bulbs in Zone 7; however, it’s important to check your Zone for preferred planting times.

In addition, refer to individual bulb packaging for planting instructions.

My friend Stacy at Stacy Ling Brick and Blooms has mastered keeping her garden in bloom from early spring until fall. For additional information about planting your spring bulbs, check out this post from Stacy.

We all need a little help from our friends, and all the information I’ve gathered for this post is based on results from those with more experience than myself. I have successfully saved my plants for the past three years, and it’s such a money saver. Practice budget-friendly gardening when you overwinter ferns and geraniums.
