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!

Many home gardeners are really missing their harvest of fresh vegetables these wintry days – and many beginners have New Year’s resolutions to become greener thumbs.

Seeds to Start

The seeds of many vegetables and beans are suitable for hydroponic sprouting into tasty young shoots that will be ready for the table in less than a week!

   Seeds such as alfalfa, broccoli, clover, lentil, mung bean, mustard, onion, radish and soybean are excellent choices for this activity plus they are invaluable in terms of their nutritional content.

Sprouting seeds on your kitchen counter takes only minutes a day, and the reward is a steady supply of fresh, crunchy shoots.

   It is important to start by purchasing some packaged seed expressly for sprouting. The directions will indicate how much is needed to produce 100 grams of sprouts. The seed-to-sprout ratio can differ substantially - anywhere from 1.5 to 8.5 units of sprouts or more per one unit of seed - so follow directions carefully and make sure your jar is large enough to accommodate all the sprouts while still leaving room for good air circulation. As a rule, begin with 1 tbsp. (15 mL) of seeds for small varieties such as alfalfa and radish, 2 to 3 tbsp. (30 to 45 mL) for medium ones such as lentil, and up to 4 tbsp. (60 mL) for large seeds such as beans and peas.

Seeds to Sprouts

Simply put seeds into jar and position screening over opening, using an elastic band to hold the covering in place. Fill jar one-third full of warm (about 40°C) water and swirl seeds around for a minute or so. With the covering in place, drain water. Refill jar one-third full of cool water and let seeds soak for four to eight hours.

   Next, begin daily regimen of rinsing seeds three times a day at roughly eight-hour intervals. Drain and refill jar with cool water, swirl seeds for about 30 seconds and drain again. Then, invert the jar so screening is at the bottom and rest it at a 45-degree angle in the bowl. Place on the kitchen counter out of direct light (place bean shoots in complete darkness, as they often taste sweeter when they're grown this way). Repeat this process for three to five days.

Simple Sustenance

You can start to harvest your sprouts once they're three to five centimetres long. Rinse and drain them thoroughly and place them in an airtight container and refrigerate immediately; they should remain fresh for up to five days.

   Clover, alfalfa, radish, and mustard seeds give rise to the delicious sandwich booster sprouts. Sprouts are one of the most concentrated natural sources of vitamins, minerals, enzymes, and amino acids.
