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’ve ever wondered how the warm weather succulent came to be a seasonally regarded indoor plant, or how to keep one going, read on!

History and Cultural Significance

The Poinsettia was named after Joel Roberts Poinsett, the first U.S. Minister to Mexico. He introduced this native Mexican the United States in 1828. In the Mexican Christmas tradition, the star-shaped leaf pattern is said to symbolize the Star of Bethlehem, and the red colour represents the blood sacrifice through the crucifixion of Jesus.

   Since the species is native to Mexico and found in the wild in deciduous tropical forest at moderate elevations, we then have a challenge to keep this plant alive and in a healthy form in our colder, northern climate.

It's Just A Rumour!

There is a common misconception that the poinsettia is highly toxic. This is not true.

   Yes, it may be mildly irritating to the skin or the stomach if it is eaten, but otherwise, there have been no documented cases of poisoning. The origin of this myth could be found in the fact that most plants of the spurge genus (Euphorbia) are indeed toxic. Fortunately, this family member is a good one!

Here are Some Helpful Hints to Get the Most Longevity Out of Your Plant:

☝️Unsleeve the plant as soon as possible as the leaves may become droopy if left too long in the wrapper. Fortunately, the plant should recover in a few days if this does occur.

☝️If you want to try to keep your plant until next Christmas then fertilize after the blooming season with an all-purpose fertilizer, repot it later in the early Summer and then introduce it to 12 hours of uninterrupted darkness come September.

Spring and early fall are generally the best times for planting trees. It has been found that newly planted trees thrive when exposed to moderate temperatures and rainfall, as they need time to root and acclimatize before the onset of intense heat and dryness of summer or the freezing temperatures of winter.

  Now whilst planting different types of trees differ in detail, all trees eventually end up in a hole. But remember not just any old hole will do.

Let’s Get Digging!

1. Some trees are buried too deeply, causing the tree roots to decline in health and condition. We have a whole other article dedicated to transplanting depth if you wish to read more, but here’s the just of it: Poor tree health results in reduced growth rate, atypical leaf size and colour, increased disease susceptibility, and reduced cold hardiness. Always make sure that the root collar flare is visible after planting; if settling occurs, reset the tree to the proper depth.

👉 Note: Many times, homeowners build a raised bed garden around an existing tree in the yard (thus burying the root collar flare) only to find within a year or two their favourite tree now is in decline. Don’t bury that root collar flare!

2. As a general rule, trees should be transplanted no deeper than the soil in which they were originally grown. The width of the hole should be at least three times the diameter of the root ball or container or the spread of the roots in the case of bareroot trees. This will provide the tree with enough worked earth for its root structure to establish itself.

3. When digging in poorly drained clay soil, it is important to avoid 'glazing'. Glazing occurs when the sides and bottom of a hole become smoothed forming a barrier, through which water has difficulty passing. To break up the glaze, use a fork to work the bottom and drag the points along the sides of the completed hole. Also, raising the centre bottom of the hole slightly higher than the surrounding area. This allows water to disperse, reducing the possibility of water pooling in the planting zone.

4. The backfill soil should be a mixture of composted manure and topsoil. The mixture should then be placed in the hole surrounding the tree just to the height of the ball or slightly lower to allow for some settling. Be careful not to compress the backfill soil as this may prevent water from reaching the roots and the roots from expanding beyond the ball.

Standing On Its Own Roots

Young trees should be able to support their own weight when they are transplanted. If the tree is unable to do so, try thinning out the upper branches to reduce wind resistance. If that is not enough, you may have to stake a tree.

Watering Your New Tree

Newly planted trees should be watered at the time of planting. In addition, during the first growing season, they should be watered at least once a week in the absence of a good rain.

👉 Remember: Regular deep soakings are better than frequent light wettings.

The classic fall-blooming Chrysanthemum varieties of burnt amber, golden yellow, and deep burgundy blooms have been enormously popular for years, and as each new fall season rolls around, there always seems to be new varietal introductions – like multicoloured pinks with the hues of sunrises - to enhance your front porch display of pumpkins, corn stalks, and gourds.

   These robust plants will produce blooms for weeks, even in the coolest of autumn weather. Their hardiness even offers versatility when it comes to their display; some gardeners prefer less labour-intensive groundskeeping and leave them in their original store pots, whereas others prefer to transplant these flowers into larger planters, window boxes, or into flowerbeds to add an easy seasonal flair.

While resilient, these plants still need some TLC. Try these tips to keep your Mums looking fresh throughout the fall.

• Choose green plants with tightly closed buds. This way when your Mums do bloom, you will be able to keep those colourful displays for much longer.
• The Mums' foliage should have a deep green colour and lots of growth at the garden centre.
• Also, make sure the soil in the container is moist when purchasing your plant, as dried out Mums may have already suffered damage.
• You'll find out in short order that your potted Mums are very thirsty plants! Water them daily and make sure the soil remains moist. A shot of liquid fertilizer to the irrigation water once a week would be great as well.

Over-Wintering Mums

Modern Mum breeding is aimed primarily at creating plants that look good in their pots at their point of purchase, sacrificing the plant’s hardiness and performance for future years - meaning when home gardeners try to overwinter these big potted plants, they are not usually successful.

   All Mum plants at garden centres are hardy, meaning that they are perennials in most climates. However, if these plants are put in the ground from August on, most won't make it through winter. The reason is that Mums planted late in the season are near, or at, the flowering stage, when their energy is focused into blooming, and they won't grow roots to sustain plants through the winter. This is why Mums should be planted in the spring if you want a perennial plant that has a spectacular autumn show!

   If you really adore your fall purchase though, you can try to over-winter your Chrysanthemums in the basement or a dark, cold closet, after the first frost. Water well and place in an area where it is totally dark and 0°C to 10°C. The plants will hibernate for the winter if you keep their roots damp. Check the pots weekly.

   In the spring, gradually acclimate your Mum plants to light and plant them out in the garden after the last killing frost, remembering to pinch them twice prior to the first of August for a full, lush plant.

   We hope this helps you to enjoy your Mums just a little bit longer! Use our Plant Finder to search for a sample of our Mum selection by your preferred colour. You can find many Mum varieties and more information at Eising Greenhouse and Garden Centre, please stop in for a visit this autumn!
