As plant people, we’ve all experienced that moment when we realize the novelty phase of that plant we brought home from the garden centre has worn off. The plant isn’t standing quite as tall, the flowers aren’t as bold, and the leaves are unravelling smaller or not at all. What is this magic they perform in the greenhouse? Perhaps you’ve provided sufficient lighting and adequate watering; there’s just one thing that is often overlooked because dirt is dirt, isn’t it?

  97% percent of plant tissue is made up of carbon, hydrogen, and oxygen pulled from the air and water, the remaining 3% is comprised of 16 other elements taken up from the soil. The quality of soil then is crucial to your plant’s health. Whether your plants are in pots or in ground, each soil type you could provide your plant offers something unique and may lack in another.

*Clay particles are even smaller than silt particles.

Resist the Urge to Slam Your Plant in Potting Soil

There’s bags and bags of rocks, sand, bark, manure, and moss on the shelves, yet the common buyer seems to always opt for potting mix. It’s fair; organic matter is usually great for plants and simple to use. However, most people don’t realize it’s merely an ingredient.

   Strictly using potting mix is like attempting to make a loaf of bread out of only flour. All those bags of other materials on the shelves are also components for a successful plant diet!

  Potting mix is a great base material, however, alone it presents risks of compacting, becoming waterlogged, can mold easily, and over time will become depleted of nutrients. Consider mixing the following ingredients into your pots, ground and raised beds to meet your plant’s required nutrients, pH level, and volume of moisture.

👍 Rule of Green Thumb: Plant roots can help you to determine the medium needed – thick, robust roots (i.e., yucca) typically enjoy chunkier materials, and smaller, delicate roots (i.e., begonias) enjoy finer materials.

Mulch and Bark Bites

• Mulch is the organic slow-release fertilizer, as it slowly decomposes, it lowers soil pH. However, may eventually compact soil once fully broken down.
• In the meantime, it creates shelves in the soil that create air pockets and prevent the soil from compacting. Mulch is a great short term medium for arid potted plants.
• If kept too wet, it can harbour fungus gnat larvae.
• Make sure when sourcing your mulch it doesn’t contain any black walnut.

Sphagnum Peat Moss

• Peat moss is used to help retain moisture and lower pH in the soil given it is harvested from bogs.
• Retains nutrients very well.
• It is difficult to rehydrate once it loses moisture.

Coconut Coir

• Coco coir, much like peat moss is used to keep the soil moist and keep pH low, however it lasts longer and is possibly less invasive to harvest.

Sand

• Grains are relatively large and do not bind, allowing for excellent drainage depending on grade.
• Adds weight to top heavy plants.
• Has no ability to store minerals itself, however, pH can vary by its content of shells, minerals like silica, or fine organic matter.

Manure & Compost

• Source these organic by products locally and ensure they’re not too hot. These additions can significantly lower pH.
• Sheep manure is usually near free of weed seeds as sheep digest seeds better than cattle and horses!

Perlite

• Perlite is a volcanic byproduct (so it floats like pumice) that helps drainage in the soil and prevents compaction – vital in the case of starting seeds.
• If a rockier, well-draining medium is required for your plant, consider perlite.
• Perlite can expand holding trace amounts of water.
• Perlite has a neutral, slightly acidic pH.
• Make sure when sourcing perlite, that you are not being sold Styrofoam balls.

Vermiculite

• Vermiculite is a recycled mineral used similarly to perlite, and too has a neutral, slightly acidic pH.
• Expands with water content.
• Can contain amounts of potassium and magnesium (as well as good cation exchange capacity).
• Runs the potential risk of introducing asbestos into your soil.

Calcined Clay Materials

• Clay materials like recycled brick bits, pottery, or lecca are typically used for arid plants as it improves aeration and drainage.
• Can raise pH.
• Can retain some water.
• High cation exchange.
• Can also be used for starting robust cuttings when kept moist.  
• Probably not ideal for inground amendments.

Maintaining Your Plant’s Dietary Needs

Perhaps we’ve crafted the perfect soil type for your plant – your plant thanks you – but over time, we will end up in the same staling predicament. Why? Because with each thorough watering, we leech the soil of the provided nutrients. Best we use the plant-specific required fertilizer for your plant to prevent nutrient loss.

   Organic sources of fertilizer such as bonemeal, composts, and manures, along with the application of lime, will improve the physical condition of the soil in terms of water and element holding ability. Unfortunately, in many cases though, manures and lime alone cannot be depended upon to provide enough available nutrients in soils with low essential element reserves.

   Let’s talk about commercial fertilizers, which can help target your plant’s exact needs much like vitamins and supplements!

The Scoop on Fertilizers

Of the essential 16 elements your plant pulls from the soil, Nitrogen (N), Phosphorus (P), and Potassium (K) are the most critical for good plant growth. You’ll recognize the three numbers appearing on your commercial fertilizer labels known as the fertilizer analysis of the product, representing the percentage of each of the three "macronutrients" in the order of N, P & K.

Nitrogen (N) is necessary for green leafy or vegetative growth which is important in crops like corn, cabbage, and potatoes.

☝️ It is important to remember that you should not use a fertilizer which is high in nitrogen late in the summer on your perennials, as it may cause a boost of growth which will only freeze as the cold weather sets in. Also, too much nitrogen in the analysis could cause too much lush, leafy growth thus inhibiting the desired flowering aspect of a plant species.

Phosphorus (P) promotes the development of flowers, fruit and roots. Crops like tomatoes, cauliflower and garden flowers.

Potassium (K) boosts plant hardiness, stem strength, resistance to disease and drought which is important to all crops, but especially in potatoes, celery and rhubarb.

👍 Rule of Green Thumb: For foliage plants, provide them with shade and lots of nitrogen, and for flowering and fruiting plants, provide them with lots of sun and lots of phosphorus!

Amending Clay

Hello Haldimand and Eastern Norfolk!

   We’re presented with the challenge of compacted, often shallow and waterlogged clay, which proves difficult but not impossible.

   Clay becomes compacted and waterlogged as it is the smallest soil particle – smaller than a grain of sand, and even smaller than silt – with rough edges that allow it to interlock and bind. In this instance, roots cannot penetrate further into the soil, are susceptible to root rot, and air pockets are slim to none.

   This, however, can be fixed with the addition and renewal of the above materials.

  Mindful that you don’t create a watery bowl in the ground (score the edges the area being worked), you can add organic matter (i.e., manure, compost, and potting soil) for nutrients, as well as mulch, sand and perlite for aeration and drainage. Annual soil particle aggregation in clay soils increases air porosity (air pockets) and is accomplished by the incorporation of organic matter that breaks down to form humus.

How To Keep Your Orchid Alive

By Ava Green

Orchids have become very popular gifts, and a great hobby for indoor plant enthusiasts who discover the wide range of colours and shapes available. Orchids are also loved for their long-lasting and exotic blooms.

While some may choose to only enjoy these tropical plants as long as they’re blooming, orchid-lovers look forward to nurturing the plant and encouraging it to flower regularly. It may be a little daunting at first, but once orchids grace you with their stunningly beautiful blossoms, you will find that a little bit of care is very worthwhile!

It’s estimated that there are 25,000 different species of orchids and over 100,000 hybrids! The ones you’ll find most readily in Ontario stores are Phalaenopsis or moth orchid, because it’s fairly easy to grow. Phalaenopsis are the best choice for beginners.

Other orchids you may find easily are Cattleyas (Corsage Orchids), Cymbidiums (Boat Orchids) and Dendrobium orchids.

While all of these may be orchids, they don’t necessarily require the same care, so it’s a good idea to check the tag for the type you have and its specific care requirements. The following is a general guide to light, water, fertilizer, and growing medium for the most commonly found orchids, but it does not apply to all breeds.

Light and Air

For most orchids, light, and lots of it, is the general rule. Place your plants within 3 feet of a window (not to the side) in the sun. South, east, and west-facing windows are all fine for maximizing the light your plant receives.

Orchids also enjoy a breeze or circulating air in your house. They do not like temperature extremes, though 15 to 20 degrees Celsius is safe. Keep in mind that the more warmth and air movement there is, the more often you will need to water your orchid.

Water

A general rule is to use water that is not hard and has not been softened with salt. Salt will kill an orchid. Rainwater, reverse osmosis, or distilled water are good choices. Chlorinated water is not an issue for orchids - high sodium levels are.

The biggest issue many people have is either over-watering or underwatering their orchids. Here is the method we recommend:

Every 5-7 days, place the pot in a container or the sink, then fill it with enough water to cover the top of the pot. Be careful not to let water collect in the crook at the base of the leaves, as standing water will rot the leaves and the plant. Once the plant’s growing medium is thoroughly soaked, remove it from the water and allow the pot to fully drain in the sink before placing it back in its saucer. 

We prefer using a container of water rather than the sink, so the remaining water can be used to water other plants.

Here’s the best watering advice we can give you: look at the overall health of both the plant AND its root system. Full, plump leaves and vibrant, green roots indicate that your plant is getting enough moisture. Puckered leaves and a silver sheen on the roots indicate insufficient water. Mushy, brown leaves and roots are signs of rot caused by too much water.

You may hear of another watering method that involves using ice cubes, but it’s controversial and not widely recommended. To quote the American Orchid Society, “Ice is for cocktails, not orchids. Never use ice on tropical plants to water them.”

“Soil” and Nutrients

Most orchids naturally grow high up in trees, where their roots cling to bark and absorb moisture from the air. At home, we try to mimic those conditions, which is why orchids are typically planted in chunky mediums like bark, coconut husk, charcoal, or perlite rather than traditional soil. While many of the roots stay inside the pot, it’s completely normal for some to grow up and over the edge.

These “escapee” roots might look a little wild, but don’t worry, there’s nothing wrong with your orchid. In fact, those aerial roots are a sign that the plant is healthy and doing exactly what orchids do in nature.

It’s worth noting that not all orchids grow the same way. Many, like Dendrobiums, are epiphytic (growing on trees) or lithophytic (growing on rocks), though some orchid varieties are terrestrial and grow in the ground. The good news is that the growing medium your orchid comes in is chosen specifically for that variety, so you can trust it’s in the right environment.

The bark that your orchid is planted in will slowly break down and become mushy. It’s a very good idea to repot your plant every two years.

It’s generally recommended to feed most orchids, and bloom time dictates which fertilizer to use and how often to feed. Begin by using a water-soluble 20-20-20 fertilizer, mixing it at ¼ the amount recommended for other houseplants. Apply this solution every 2 weeks in the summer and every 3 weeks in the winter.

“The orchid, with its many forms, is a reminder that life is full of surprises.” — Leonardo da Vinci.

Lastly, here’s an orchid fun fact: While we have been talking about tropical orchids in this article, there are also orchids that grow right here in Ontario! That’s right, there are over 50 species in this province, including the much-loved Pink Lady’s Slipper (Cypripedium acaule).

As we all start to settle into our new routines and get the hang of homeschooling (common core math, anyone?), we're quickly realizing how important it is to have some variety in our lives. Too much monotony can make us pretty squirrelly—kids especially—so breaking up long stretches of time indoors with fresh air and exercise really helps the cause. After all, that's why schools have recess. 

Time spent working is more productive and valuable when you get the chance to get some sunshine, so it's good to try and squeak in a couple of 20 - 60 minute activity breaks outdoors. It isn't always easy to think of activities to keep kids occupied when you're juggling all the other duties at home, but these six ideas for outdoor games should go over well with the little ones. 

5 Creative Outdoor Games For Kids 

Soak up some sun and enjoy some playtime with your kids; it's amazing how quickly it can lift the spirits and give you a second wind to tackle your next project. These fun activities will require you to help with setup and supervision, but you'll still be able to get a chance to kick back and enjoy a cold drink in a lawn chair while the young ones run around. A little exercise and a little relaxation—the best of both worlds!

Make a Chalk Obstacle Course

A set of rainbow chalk and a little imagination is all you need to create a wacky obstacle course all the way down your sidewalk. You can help them with the colouring, and then sit back and watch while they run through it over and over. Of course, there are the classics like hopscotch, but you and your kids can probably come up with some more creative ideas. 

For example, you can colour a long stretch of bright orange and red lava, then add a few "stepping stones" to hop on. Draw a big, long, slithering anaconda and walk on it like a tightrope! Add in some squares with different actions like "Hop on one foot ten times," or "Spin around five times." Use the stopwatch on your phone to time their runs through the course and challenge them to try and get the fastest time they can! 

Paint Some Rocks

Rock art can be a fun, inexpensive outdoor art project that kids of all ages can enjoy. The little ones can go the abstract route, covering rocks with fun splashes of colour (these actually look really pretty lined up on a windowsill or placed throughout the garden!). Older kids with more developed motor skills can try painting scenes on rocks or transforming them into their favourite characters. To avoid getting paint on the grass or cement, put an old bedsheet or some sheets of newspaper down. Make sure to provide plenty of paper towels along with a basin full of water!

Melt Old Crayons Into New Ones

If you've got cookie cutters, tin foil, old crayons, a cookie sheet, and a sunny afternoon, then you can pull off this super fun outdoor activity that gives new life to old, broken crayons. Cover the cookie sheet in tin foil and arrange the cookie cutters on top. Peel off any labels remaining on the crayons, snap the bigger ones in half, and put a mix of assorted coloured crayon bits in each cookie cutter. After you've got them all set up in the sunshine to start melting, you can go back inside for another activity, and then come back out to retrieve them once they've melted. Place the cookie sheet on the counter to cool off, and then once they're solid, pop out your new crayons and get colouring!

Let Them Power Wash The Windows

Okay, hear us out—kids love any opportunity to play with tools, and a sprayer nozzle on the garden hose is arguably the safest tool out there. If your windows are looking a bit mucky now that the snow has cleared, let your kids blast off all the dirt! You'll be amazed at how eager they are to help you clean. "Power washing" with the hose is definitely one of the most fun chores around. If they can't get enough, ask them to give the patio furniture or the family car a good rinse!

Plant A Kid-Friendly Garden

Of course, we're a little biased, but we think gardening with kids is one of the best outdoor activities imaginable. It's like a long-term, hands-on science lesson that results in some pretty spectacular end results. Sprout some seeds on the windowsill, or pick up some small starter plants. Grab them some child-sized garden tools and gloves so they can dig up some holes and get all their flowers and vegetable plants in place.

Encourage them to make some little signs to stick in the garden so they can keep track of which plant is which. It's a great way to expand on their vocabulary and work on their printing skills! Make a plant journal for them, and take note of exciting new developments or growth spurts in the garden. They'll love the sense of ownership they feel for their personal gardening project, and at the end of the summer, you'll have a cool memento to hold onto and look back on.
