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).

If you can’t wait for Mother Nature’s next great colour show, the time is now (mid September) to get rolling on those early spring flowering bulbs! Even though you can start planting in October or early November, buying bulbs now is advantageous as the selection at your local garden centre is at their best. Being the very first to bloom during the last dreary days of winter, bulbs announce that spring is returning once more, and as you think about the colourful show of tulips and daffodils next year, remember all spring’s groundwork begins now!
Your bulbs may be planted in your lawn, rock beds, at the foot of trees and bushes, in annual or perennial flower beds, or even in flower stands and pots. Combining the emerging fresh colors and textures of bulbs with the established foliage creates a harmonious relationship opportune for a complimenting or contrasting garden-scape. With a bit of planning and creative selection you can easily extend the joy of having spring flowering bulbs in your garden from a few weeks to several months, furthermore, planting bulbs amongst perennials offers that the new growth of the perennials will hide the fading foliage of the bulbs once they have finished flowering! Not long after the fading of the bulbs most perennials themselves will bloom, smoothly extending the sequence of flowering plants for you to enjoy.
Read on for all there is to know about planting bulbs!
Buying Your Bulbs:
When buying, look for nice, plump, firm, bulbs. Avoid those with scars or that feel spongy to the touch. The general rule is the larger the bulb the bigger the plant. If you're buying daffodils, look for bulbs that have two or more "noses" as you will get extra flowers for free!
To have a good display of colour in your garden, right from March to the end of June. Be sure to check the blooming times on the packages and get a variety of early, mid and late-blooming spring bulbs.
👉 Tip: To extend the season, plant some bulbs in places where the sun beats down in early spring and some in cooler, shady areas of the garden allowing them to emerge in later spring.
Planting Your Bulbs:
When planting, the soil must be warm enough under the surface to stimulate a little root growth prior to the winter freeze. Winter chilling is necessary to break the flower bud dormancy (vernalization) to have our bulbs produce blooms in the spring (see below how to force bulbs if you’re reading this in the spring).
Remember to plant your bulbs with the pointed end up! If it doesn't seem to have a pointed end, look for the flatter side and evidence of roots, which is the end that goes down. If you still can't be sure, plant the bulb on its side and it will figure out the proper direction by itself!
The rule of thumb is to plant the bulb two or three times as deep as the bulb is tall. The depth is to the base of the bulb, not the top. Typically, 8 inches (20 cm) for big bulbs such as daffodils, tulips and hyacinths and 5 inches (13 cm) for small bulbs like grape hyacinths and crocus. Plant in well-drained soil, cover up, water well and wait for spring.
In a wide hole, place bulbs - so they aren't touching - in threes, fives, or sevens per hole for the most natural look. You can throw a handful of bonemeal in the planting hole and mix it lightly with the soil, this will give your bulbs a good boost for the best bloom. Water to the depth of the hole.
Tulips, daffodils and other spring-flowering bulbs require a long period of cool temperatures to undergo the biochemical process that allows them to flower. So, in the fall, get them in the ground ideally six weeks before hard freezes to give them the time they need to develop strong roots.
Fertilizing Bulbs:
Bulbs contain the nutrients they need to bloom their first year, but a fertilizing program will keep plants healthy and ward off diseases and pests. Compost and manure are two good organic fertilizers that not only enrich the soil but ensure a good soil structure for bulbs. Additionally, organic supplements can be used to add nutritional balance. Compound mineral fertilizers can also be applied, however, check the label to see if fertilizing is appropriate for your bulbs and the best time of year to do so. Top-dressing with fertilizers like 9-9-6 slow release or either 8-8-8 or 10-10-10 soluble fertilizers are examples.
Once a bed of spring flowering bulbs are established, the process of naturalizing occurs which simply means that a bulb flowers again after the first year and starts producing more bulbs on their own. However, they will need your help to get the food they require to recharge and regenerate for the next season's bloom.
Some Helpful Tips:
- Squirrels enjoy the taste of tulip bulbs if they are easily accessible but not so with daffodil bulbs; interplanting the two together and/or mulching the garden will help protect them.
- Resist the urge to tidy up fading foliage or mow over it as the plants require about six weeks to build up reserves for the next season.
- Deadhead the tulips as the formation of seeds will sap the energy from the bulb. Daffodils & other bulbs do not require this action.
Forcing Bulbs:
Now if you can't wait for spring to smell the fragrant hyacinths, or you missed the fall planting, why not try your hand at bulb forcing?
All you have to do is plant any extra bulbs in a pot with a drainage hole. Choose a pot that is at least twice as deep as the bulbs to allow for proper root growth. Fill the pot half full of soilless potting mix. Then place as many bulbs as possible in the pot, without letting them touch. For a thick show, layer more than one kind of bulb in the same pot; place larger bulbs on the bottom as they will grow around the smaller ones. A six inch-wide pot holds up to six tulips, three narcissus (daffodils), or 15 minor bulbs, such as crocuses or grape hyacinths.
Cover the bulbs with potting mix, leaving their tips showing. Water the bulbs thoroughly. Label with name and date; loosely cover pot with a paper bag. Place in cool (1-7 degrees Celsius or 35-45 degrees Fahrenheit), dark place for chilling such as an unheated attic, basement, or attached garage or in a 12 inch-deep trench covered in a tarp.
Check moisture in pot periodically keeping the soil damp but not wet. When chilling is complete, you'll see roots poking out of the bottom of the pot and green sprouts emerging at the bulb tips. It's time to move the potted bulbs into a warm room.
Chilling and Blooming Times:
- Daffodils: 12-15 weeks of chilling; 2-3 weeks to bloom after chilling.
- Tulips: 10-16 weeks of chilling; 2-3 weeks to bloom after chilling.
- Crocus: 8-15 weeks of chilling; 2-3 weeks to bloom after chilling.
- Grape hyacinth (Muscari): 8-15 weeks of chilling; 2-3 weeks to bloom after chilling.
- Iris reticulata: 13-15 weeks of chilling; 2-3 weeks to bloom after chilling.
- Snowdrop (Galanthus): 15 weeks of chilling; 2 weeks to bloom after chilling.
- Hyacinth: 12-15 weeks of chilling; 2-3 weeks to bloom after chilling.
