Usually, by the time February or March rolls around, I’m pretty tired of the health crazes like extreme diets and exercise plans I’ve been trying for the fifth year in a row. This year, let’s take a look at something that naturally supports our good health, both mental and physical. It’s time to stop and “smell the flowers,” so to speak.

Mental and Physical Health

Many gardeners already realize this, but studies are showing that simply seeing greenery can benefit our mental health. Whether it's a walk in the woods or a handful of houseplants, seeing green leaves makes a difference for humans! Research shows that it helps boost our mood and improve how we get along with people. Who doesn’t need a mood booster during cold, dark days? And getting along with people, well, the world just needs more of that, too, doesn’t it?

You may also already know that tending to plants reduces stress, but did you know that science is proving it? PubMed published a study stating:

"Interaction with indoor plants may reduce psychological and physiological stress by suppressing autonomic nervous system activity in young adults: a randomized crossover study."

This isn’t the common thinking about working outside in the garden increasing physical strength and stamina. It’s a study that examines our autonomic nervous system, the one responsible for automatic and essential bodily functions we don’t even think about, like breathing. The study compared participants performing two tasks: one on a computer and the other doing plant transplanting. The results suggest that interaction with plants indeed reduce stress without us even thinking about it! No task that requires willpower, just daily tending to plants like transplanting, watering, dusting, pruning, or turning the pots to get sun on the flipside.

So plants boost our mood, improve interactions with others and physically reduce our stress levels without us even trying. It’s no wonder we just feel better when we’re around plants.

Air Quality

Research also shows that indoor air pollution is often worse than outdoor air pollution. VOCs (Volatile Organic Compounds) from washing detergents, paint, furnishings, and building materials, as well as bacteria, fungal spores, and dust, negatively affect human health.

Fresh air can counter the impact of indoor pollutants, but often it’s too cold to open the windows in the middle of winter. When you can’t let fresh air into the house, indoor plants will help. We know that growing trees outdoors has a massive impact on air quality and the health of the planet, and inside our home, tropical plants contribute in the same way. The contribution of each type of plant varies, so having a variety is a very good idea.

What to Grow

Here’s a list of easy-to-grow, green indoor plants that Eising’s resident tropical plant expert, Courtney, and the UK’s Royal Horticultural Society (RHS) recommend:

Aglaonema ‘Silver Queen’ (Chinese evergreen ‘Silver Queen’)

Aspidistra elatior (common Aspidistra, Cast Iron plant)

Chamaedorea elegans (Parlour Palm)

Chamaedorea seifrizii (Bamboo Palm)

Chlorophytum comosum (Spider Plant)

Crassula ovata (syn. Crassula portulacea) (Jade plant, Jade tree)

Dracaena fragrans ‘Janet Craig’ (Dragon Plant)

Dieffenbachia ‘Tropic Snow’ (v) (Dumb Cane)

Dracaena marginata (v) (Madagascar dragon tree)

Epipremnum aureum and ‘Marble Queen’

Ferns - many types

Ficus elastica (Rubber tree, Rubber plant)

Hedera helix (English ivy, common ivy)

Howea forsteriana (Flat Palm, Kentia palm)

Rhapis excelsa (Bamboo Palm, Lady Palm)

Sansevieria (Snake Plant) - many types

Spathiphyllum sp. (Peace Lily)

Syngonium podophyllum (Nephthytis)

Zamioculcas zamiifolia (ZZ plant, fern arum)

Is there a downside to having houseplants? Yes, if you have small children or pets, be mindful of the plants that can be toxic if ingested (see resources listed below).

While many of us in Ontario focus on “nice” weather and getting outside to garden, it’s pretty clear that our indoor plants do much of the heavy lifting to improve our health through the cooler seasons. Even if you don’t have a “green thumb”, it’s worth giving tropical, indoor houseplants their well-deserved space in our homes, hospitals, offices, nursing homes, classrooms, restaurants…or any indoor space!

Got cabin fever? Perhaps you’re going a little stir crazy looking out the window and seeing the drab, limited pallete in your seemingly lifeless outdoor space. It’s important to embrace this time of year as the composting and cleansing part of Earth’s cycle before spring’s renewal – but that doesn’t mean we should be trapped inside forever. Here’s a winter/early spring list of activities, divided by indoor (Part 1) and outdoor (Part 2), for the gardener and yard keeper.

☝️ First, let’s quickly note the important activity happening under the snow – and how your actions now will affect the summer garden!

What's Going on Outside When We Aren't Paying Attention?

Before heading out to attend to these jobs have a look at the ground beneath you.

   If it is frozen hard you are good to go but avoid treading on the crowns of perennials.

   If it has been warm and sunny and the soil is warm and dry, consider laying down a few planks to walk on.

   If the soil is soggy then postpone those tasks until it has dried. What we are trying to protect is not your shoes but the soil itself.

   Ideally, soil is comprised of 50% solid materials such as minerals and organic matter in various stages of decomposition, and 50% open air space. Water from rain or melting snow enters the soil, displacing the air. Wet soil is easier to squish down and that process is called compaction.

   While walking on wet soil would not seem to have much effect, it occurs within the depth where annuals, perennials and lawn grasses have their roots. Compaction makes it harder for roots to grow through the soil. Roots can grow stronger to push aside the soil particles, but tougher roots are less effective at drawing in nutrients and moisture. Removing air spaces makes it more difficult for water to percolate down so compacted soils remain wetter. Plants don’t grow as well and are more prone to insect damage.

   The freeze/thaw cycles of fall, spring, and winter heave the soil relieving compaction and aerating the soil; a good way to start the growing season. Preventing further damage to the soil is relatively simple. Stay off it when it’s wet. Later, consider using pavers or pathways in heavily travelled areas of the lawn. Aerate the lawn with a machine that removes small plugs of soil and redistributes them over the surface. In beds and borders, add compost and use a thick mulch layer to absorb some of the pressure.

 And stay off it when it’s wet.

With this in mind, we can appreciate Earth’s renewal capabilities, as well as prevent destroying our yards and gardens!

Part 1: Activities for When it’s too Cold and the Soil isn’t Ready Yet

Yup, it’s bleak out there. It’s time we make that herbal tea and turn our attention to creating a lively, green indoor environment, even if just to get us through the winter. Here’s a to-do list for trapped gardeners and plant enthusiasts to make the most of our wintry sentence.

Indoors: Get Inspired!

• Expand your knowledge: There’s an endless plethora of botanical media at our fingertips, use this down time to learn more!

• Sustainable winter crafts: Why buy décor and gifts when you can make them from materials found outside? Perhaps you dried flowers or found some interesting seed pods – time to display them, and perhaps, eventually compost them.

• Visit botanical gardens: Ely’s boyfriend took her to the Royal Botanical Gardens as a birthday gift last year! Botanical gardens are a great way to experience interesting plants being preserved in a welcoming environment that differ from the dreary winter outside.

• Get floral: Try buying flowers and displaying your own arrangements! Colour is something we sometimes lack in the wintry months, and this is a good way to introduce it impermanently.

Indoors: Thinking Ahead!

• Use this winter down time to plan the next garden season - find more here on garden planning. 

• Use a garden journal to assist your garden planning - see here inspo for garden journaling. 

• Consider planning companion plants - see more here on companion planting.

• Go pot shopping – your local greenhouses and ceramic shops would love your support in the winter.

Indoors: New Beginnings!

• Bulb forcing and small science experiments: Flowering bulbs like amaryllis (more on amaryllis here) aren’t just a holiday splendor! Now is also the time to create cuttings to share with friends.

• Invest in winter fruiting botanicals like indoor fruit trees. Small, potted citrus by the window don’t only liven up the place but offer nutritious treats in the winter. Consider a calamondin!

• Microgreens - see our blog about it! When it’s too early to start seedlings that will go in the ground, you can still garden right on your kitchen counter.

• In late winter, start seedlings: but make sure you don't do so too early! Untimely seedlings can be too leggy before it's time to plant them outside - learn about hardening off seedlings here.

Part 2: When the Soil IS Ready!

Suit up!

Outdoors: Don’t Fall Behind!

• Appropriate seasonal décor: It goes without saying stringing lights and ornaments everywhere is good for the spirits in these dreary months… however 😬… come February, they seem to lose their vigor. Taking the décor down in preparation for new exciting things to come is also good for the soul! Remember to recycle your Christmas tree (see how here)!
• Turn your compost! Perhaps you’ve faithfully continued to add to your compost all year – your garden thanks you! On a warm day, remember to turn it and aerate it so it’s ready for spring.
• Cover all your bases: Make sure to prevent rodents from damaging your tree bases by wrapping them well above the anticipated snow level – so rodents can’t chew your unprotected trees with the helpful elevation of snow!

Outdoors: Get Inspired!

• Go for nature walks: if you can safely go for a walk, hit the trails or stroll around your neighbourhood! A slow-paced change of scenery will help to fight your cabin fever, keep you active, and help you gather inspiration from the natural world.

• Visit your local maple syrup producers for tours.

• Don’t forget our critters: Provide winter homage and appropriate food for our nonmigratory friends (i.e., hutches and feeders) outside windows where pets can observe nature too!

Outdoors: Thinking Ahead!

• Winter weeding: Some tough varieties of plants have evolved to use other plants’ winter dormancy to their advantage, tugging them out now will ensure that you and all the wanted plants in your garden have a fair start this spring.
• Manage snow piling: Heaped snow piling can kill plants including lawn, as well as introduce gravel and debris to areas where gravel is not wanted. Make sure your snow piles aren’t suppressing anything you’d like to live this summer.
• Early spring: Perhaps ice storms and plows have done a number on your trees and shrubs - prune broken branches to prevent pests and disease from entering your plants.
• Litter control: pick up the debris revealed by melting snow so it doesn’t venture farther into natural habitats or tempt wild animals to hurt themselves.  

Outdoors: Start Something New!

• Cold hardy crops in cold frames: Cold frames are doable! Use recycled materials - Victory gardens often used car windshields and old windows – to construct in-ground beds facing the sun (southwards) for passive solar heating.

• Winter sowing: Find more on winter sowing here.

We hope these suggestions help you stay green this spring and winter! For more gardening activities, see our other blogs here. We hope to see you this spring (March 5^th, 2026) at Eising Greenhouses and Garden Centre! 🌱❄️
