‘Tis the Season … for Poinsettias!

By Cheryl Harrison, Master Gardener

When I was growing up, my mother always had a big green and red poinsettia sitting in the centre of the dining table during the holiday season. By the middle of January, it had lost all of its leaves so out it went in the trash. Oh yes, we also called it a “pointsetta”.

In Mexico, where it grows wild as a leggy shrub or small tree, the native plant (Euphorbia pulcherrima) has been associated with the Christian Christmas holiday since the 16th century. Thanks to Joel Robert Poinsett, the first U.S. Ambassador to Mexico, poinsettias were introduced to the United States in 1825. They did not really take off, though, until the California based Ecke family grew plants using a grafting technique discovered by Paul Ecke Sr. in the 1960s.  They began aggressively marketing the holiday season blooming poinsettia as a holiday tradition. In the 1980s, John Dole identified the technique used by the Ecke family to produce their compact poinsettias. This led to many more growers entering the retail market.

Poinsettias are members of the Euphorbia family. The brightly coloured “flowers” are actually bracts (modified leaves). Their bright colour helps to attract pollinators in the wild.poinsettia1

When purchasing poinsettias, look for an erect plant that has dark green leaves down to the soil and fully coloured bracts. The actual flowers, located at the centre of the bract, should be immature and red-tipped or green, not yellow with pollen because these more mature blooms will not last as long as the immature blooms. Plants displayed in plastic sleeves or crowded together may be stressed and deteriorate quickly after purchase. When purchasing any plant, always check for disease or insects. Yellow leaves, wilt or the presence of insects (check the underside of leaves too) always indicate problems and a plant that you do not want.

Poinsettias are not poisonous to humans but may cause pets to experience vomiting and diarrhea if consumed. Like all Euphorbia, damaged poinsettia stems and flowers exude a white sap that may cause skin irritation to susceptible individuals and pets.

There are over 100 varieties of poinsettias. They come in many colours from the traditional red to white, pink, cream and marbled or speckled.

Poinsettias prefer 6 hours of indirect light each day away from heat registers and cold drafts. Water the plant when it is dry but do not overwater because it may wilt and drop its bracts. (I think that is likely what happened with my mother’s poinsettias!) Allow the water to drain into a saucer after watering then discard this water. Do not let your plant sit in water. If you would like to keep your plant past the holiday season, fertilize it once a month with a houseplant fertilizer once the plant has stopped blooming.

Poinsettias may be put outside in the summer after all danger of frost has passed. But if you would like it to rebloom during the following holiday season, bring the plant back indoors before frost. Then, beginning in October, keep it in total darkness for 14 hours each night. The combination of total darkness and warm, bright days should cause the bracts to colour. This might be fun to try but to guarantee that you have a blooming poinsettia during the following holidays, purchase a new one and compost your old plant.

Poinsettias have long been associated with the holiday season. They come in several colours which will help to add holiday cheer to any home decor. Enjoy them while they last!

10 Great Christmas Gifts for Gardeners!

 

By Mary-Jane Pilgrim, Master Gardener

It’s not too early to think of Christmas gifts for the special gardeners in your life. Every mini-cactus-755542_640gardener has a long list of things they wish they had because many of these items will make their gardening hobby just a little bit easier.  Also, most of them will rarely treat themselves.

Christmas gifts for gardeners can be purchased at nurseries that remain open in the fall, at local home & garden stores, online at Lee Valley Tools or via any other local or online suppliers.  Hopefully, the following suggestions will help you to surprise the green-fingered folk in your life.

  1. Plants! A small succulent planter, a unique and weird looking cactus, a fancy orchid, an amaryllis bulb or an african violet for indoors can spruce up a cold winter.
  2. Basic Garden Tools.  Who among us doesn’t need another/new garden tool?
    1. Lee Valley Root Knife (my go-to weapon)
    2. A new pair of secateurs (pruners).  My choice is the Felco #6, great for smaller hands.
    3. A padded garden kneeler or good quality set of knee pads
  3. Salves and Soap, Especially for Working Hands. There are many items like garden salves and soaps with hydrating formulas & great scents that will always be appreciated by anyone unwrapping them on Christmas Day.
  4. For our Feathered Friends. A  good squirrel-proof bird feeder or a birdhouse, and some good quality birdseed will go miles to attracting useful, pleasant-sounding visitors to your yard all winter.bird-feeder-4032907_960_720
  5. Magazines. A subscription to a Canadian gardening magazine about growing perennials or native plants or about water gardens is always appreciated and will delight the recipient monthly or bi-monthly.
  6. GLOVES!  My favourites are the nitrile Gardena brand — stretchy but grippy.  I go through several pairs of these each season.
  7. A transplant shovel, a new garden hoe or a step-on weeder. These items are not “must have” but “would be nice” so gardeners will rarely purchase them for themselves.  Believe it or not, there have been advances in these tools in the last 20 years!  For example, my favourite new shovel has a super-sharp cutting edge, and an enlarged “step on” bracket so the middle of my foot doesn’t get sore with heavy digging.  Very nice.
  8. Stocking Stuffers. Stocking stuffers of heirloom seeds, plant markers, a mini nail brush, some twine or plant ties are welcome unique gifts.
  9. A Year Round Gift. An inexpensive membership to local Horticultural Society like the Peterborough Horticultural Society offers you discounts at many local nurseries, plant exchanges, plant shows, socializing, and the opportunity to hear good speakers throughout the year. A great stocking stuffer for $20.
  10. PGS-logo-tinyA Garden Show! Treat someone to a trip to Canada Blooms or the awesome Peterborough Garden Show — $10 each for “enjoy all weekend” admission on April 24, 25 and 26, 2020; our 20th fabulous show!

So, why don’t you surprise your favourite gardener with a garden-related gift this Christmas season?  Hoping that this list helps with your decisions.  Happy shopping!

Holiday Cactus Conundrum

by Emma Murphy, Master Gardener

Definition of conundrum
A confusing and difficult problem or question

Despite the shortening days and dark and dreary November weather, every year around this time I am delighted to see members in my various gardening groups posting photos of their “Christmas cactus” in bloom. The colours are many and varied – from red to pink to white to some lovely peach selections. People post amazing stories of plants being handed down from generation to generation and being over 100 years old.

The conundrum? They are generally not “Christmas cactus”. Since education is a big part of the role of Master Gardeners, I thought I would offer some explanation of the various types of indoor cacti we see here in Ontario (and Canada) and how to figure out what type of cacti you have!

There are actually three types of holiday cacti – all theoretically named for the time of bloom (although that gets messed up depending on whether you are north or south of the American/Canadian border!). The three types are:

  • Thanksgiving Cactus (Schlumbergera truncata)
  • Christmas cactus (Schlumbergera bridgesii [also S. buckleyi])
  • Easter cactus (Rhipsalidopsis gaetneri [also Hatiora gaertneri])
National Garden Clubs Inc.

They are all called “leaf cacti” because the plant bodies are flattened and the leaves are actually stems. These type of cacti are epiphytes from the tropical treetops of the rain forest and natural forests of Brazil and require similar care, even though they bloom at different times of the year. In their natural habitat, they grow on trees or rocks in habitats that are generally shady with high humidity, as opposed to their desert-dwelling cousins. So they don’t need bright sunlight and they don’t have nasty spines!

Most people have the Thanksgiving cacti, which bloom between November and January. Christmas cacti bloom in December, and Easter cacti in April/May.

The leaf stems (and to some extent the flowers) tell you which type you have, rather than the bloom time. Thanksgiving cactus is often known as “lobster cactus” because the edges of the leaves are hooked, giving them a claw-like appearance. The Christmas cactus has leaf projections which are more scalloped or tear drop shaped. The Easter cactus has very rounded edges which are centralized on the leaf.

christmas-cactus-277691_1280

Easter Cactus

All three cacti are short day plants, so in order to induce the plant into bloom it must have 12 to 24 hours of darkness and cool temperatures. If you have put your plant outdoors over the summer or purchased it recently it should be kept in a cool, dark location until it sets buds. A seldom used bedroom or lower level is the ideal place. The Christmas and Thanksgiving cacti require approximately 6 weeks of short days in order to bloom (the Easter cactus requires 8 to 12 weeks to bloom). When the buds appear it can be brought into a warmer area. If it starts dropping buds it could be due to drafts, too-warm temperatures, too much water or direct sunlight.

FUN FACT! Unlike Christmas poinsettias, Christmas cacti are not toxic to dogs and cats, making this cat mum very happy.

Growing Tips

Since they are from the rainforest, they like acidic well drained soils. Use a cactus mix and add perlite, vermiculite and orchid bark. Do not overwater – why most of them die! Neglect is better than over watering. Water when the top 2 inches of soil is dry. Mist them frequently to increase humidity and fertilize them with a all purpose fertilizer. Those who hate repotting plants can take comfort in knowing that holiday cacti bloom best when they are slightly pot-bound and only need repotting every 3 or 4 years.

Common Problems

The most common issue you might face is dropping buds, which can occur when there is any type of change in the temperature, lighting, humidity, or the amount of water the plant is receiving. Try to keep the soil moist, the temperature a steady 15 to 20 degrees Celsius, no fertilizer in the late summer to fall months, and 14 hours of darkness each day. Other issues that could affect your cactus include stem rot (this fungal issue occurs when the soil is too damp – start a new plant before the infection spreads too far), root rot (happens if roots get soggy, so remove that root so it doesn’t go further up the stem, which might kill the plant), and Botrytis blight (which is grey mold and can be removed if discovered early).

When they have finished blooming, these cacti need at least two months rest. Give almost no water or fertilizer during this time. The Thanksgiving and Christmas cacti may bloom again in the spring, but probably with less (and smaller) blooms.

While holiday cacti appear to be a bit finicky, if you understand where they come from, and what they need to be happy, you may be able to successfully keep your holiday cactus for 100 years!

 

Pot, eh?

By Mary-Jane Parker, Master Gardener

This past growing season was my first foray ever into growing marijuana. I tried this because I want to attempt to make a salve that I have been purchasing locally for arthritis (which, by the way, seems to work for me!)

marijuana-101796_960_720I started my seeds inside under lights. When I planted the seedlings outside, one went into the ground in my garden and the other went into a 5 gallon bucket with holes drilled in the bottom. The bucket plant went into my little greenhouse.

I did not fertilize either plant regularly – maybe 3 times the whole summer – but I did water the potted plant pretty well daily. I gather from other growers that I should have fertilized a lot more and then held back on the fertilizing later in season to clear chemicals out of the plants.

I thought this would be a good way to test growing techniques – greenhouse as opposed to outdoors but in the end it was not. I had planted 2 varieties that had very different characteristics. One had a beautiful bluish, reddish tinge to it and the other was twice as bushy.

Both plants ended up being well over 5 feet tall with lots of flowers. I cut them down before first frost and hung them in the greenhouse with shade cloth draped overhead.

So now, I am not sure if all the work was worth the effort and I haven’t even made the salve yet. I don’t know how the hippies from the 60’s and 70’s did it. I was told to trim off all the leaves before I hung the plants. That took an incredibly long time. And apparently I will have to trim the dried flowers off in the very near future. The marijuana plants themselves are kind of interesting architecturally but they stink. Birds for the most part avoided them and I don’t think I saw even one bee on them and I have lots of bees here. At any rate, I will make the salve and reserve judgement until then. We have to try new things, right?

Facebook Groups for the Green Community

By Mary-Jane Pilgrim, Master Gardener

Two weeks ago, I wrote about iPhone and Android apps that can help you to identify plants & trees, know where/when/how/what to plant and also help you to connect with like-minded people for discussion.  Facebook groups serve similar purposes.  At this time of year, these groups are eye-candy for the green community as they often remind us how few days are left until spring, where to attend local (indoor) green/gardening events, and how to care for those houseplants that need a fb groups bloglittle TLC.  During the gardening season, these groups magically transform to become a forum for a little bragging for those inclined to share pictures of the results of their hard work, and also a forum for those needing a little help.  I’ve posted a plant picture to one of them, and had a definitive answer to an identification question in literally less than ONE MINUTE (Thanks, Jeff Mason!).

Here’s a list of some of the (mostly local) groups that I’m a member of.  There certainly are a lot more!  Most are public, but don’t let the ‘closed group’ label scare you.  If anything, closed groups are completely welcoming to gardeners!  They just may ask you to answer a few simple gardening questions to make sure that the group doesn’t get infected by spammers.

Winter in Ontario – A Gardener’s Survival Guide

by Emma Murphy, Master Gardener

If you’re a passionate gardener like me, right now you are buried in the snow and cold of winter and suffering from the January blues. You dream of your garden every night, envisioning the bright colours and textures and green of your summer paradise. You consider heading south for a vacation, not just for the warmth and sun but just to see some incredible tropical plants and green things. You start thinking about moving to some place where you can garden year round…

But I digress. Don’t get me wrong. I like the winter season. My body needs a rest from the garden, I need time to plan for next year’s garden, it’s time to order seeds and attend garden workshops, and there are so many good gardening books and blogs to read.

I thought I would share my Top 5 Ways for Gardeners to Survive Winter. I have more ways, but that’s another story..

1. Review your Garden Photos

I love to spend particularly dull winter days reviewing photos of my garden from last year or previous years. Digital cameras and our smart phones make it so much easier these days to capture our gardens in all their glory, so take the time to enjoy the beauty you created when you need a pick up. I’ve sprinkled a few of mine throughout this blog (you’re welcome!).

2. Join a Local Garden Club, Horticultural Society, or Master Gardener Group

Nothing feels better than sharing your gardening love with others who share your affection for all things growing. Find your local Ontario Horticultural Society, or think about becoming a Master Gardener. In my area we have many wonderful horticultural societies including Lakefield, Peterborough, NorwoodOmemee, Ennismore, Bobcaygeon, and Fenelon Falls. I meet interesting people, chat about gardening issues or successes, and get to hear from terrific presenters. Great value for money. I also love being a Peterborough Master Gardener, sharing my love and knowledge of gardening with others.

3. Seed Catalogues!

I am relatively new to growing my own plants from seed, as my garden is mostly full of perennials and shrubs. However, after a Master Gardener field trip to William Dam Seeds a few years ago, a new interest in growing dahlias (after being inspired by a vendor at the Peterborough Garden Show) and a new vegetable garden in our back yard (courtesy of my husband – the veggie gardener), I have entered this world, and there is no turning back. Reading through hardcover or online seed catalogues (even if you don’t buy anything!) is guaranteed to put a smile on any gardener’s face. Google Canadian seed companies and many should pop up.

4. Find a Great Garden Blog or Website

There are so many amazing gardening blogs and website out there. I tend to follow those who have similar growing conditions to me (Zone 4b, harsh winters, Central Ontario) but I do have several (including a few in the UK like The Frustrated Gardener and the Anxious Gardener) which I like to just view and enjoy. Some of my favourites below.

The Laid Back Gardener (Quebec)

The Impatient Gardener (southeast Wisconsin)

The Gang at Savvy Gardening (Pittsburgh, Halifax, Dundas)

The Gardening Girl (just north of Toronto, Ontario)

5. Buy a new Houseplant (or 2, or 10)

Confession – I am a much better gardener outside than inside. While I love seeing the greenery all winter, our harsh interior conditions (furnace heat and no humidity) are not ideal for houseplants. However, the arrival of two rambunctious kittens into our home in October sparked a review of my houseplants. So many plants are problematic for felines that many got rehoused with friends or just thrown out. A week ago I had a craving for some greenery, so I ventured out to a local nursery with great houseplants (Burley’s Gardens) to find some ‘safe’ plants. I came home with some Peperomias, a prayer plant (Maranta leuconeura), African violets, a money tree (Pachira aquatica), and a Phalaenopsis orchid. It appears all of these are relatively safe for cats. There is a good list here of plants that are toxic (or non-toxic) for cats. However, it’s just a general list – it depends on how much is ingested, what plant part, age of cat etc. etc. Do your research.

I hope these ideas help get your through these cold winter days and nights. And just remember, all that snow provides a lovely warm blanket for your plants, so thank Mother Nature for that and dream of spring!

Can’t wait for Kermit to reappear at my pond.

Caring for Your Houseplants in Winter

By Chris Freeburn, Master Gardener

For avid gardeners, winter months are a resting period with little to do but read about gardening and plan for spring. But we also need to take more care with our houseplants during this time as conditions in our homes have changed from months where windows are open and furnaces are not running.

To give your plants the best chance to stay happy and healthy, remember these four important factors.

Water

Most plants do drink less in the winter months so you can let them dry out between watering. However, plants like asparagus fern, anthurium, dracaena and ferns will still want to be kept moist. Check the soil an inch down or feel how heavy the pot is to be sure you are giving those plants enough water. Always fill your watering can and let it sit for a few hours before using. This allows the water to come to room temperature and also gives time for any chlorine or other chemicals to dissipate. Plants like jade, sansevieria, succulents and cactus will still want to be dry through the resting period.dscn6541

Temperature

Palm, croton, dieffenbachia and most tropicals prefer it warmer while ivies, wandering jew, cyclamen and jasmine like it cooler. So if you have your cyclamen in the same room as your fireplace, it might not be happy. Watch for drafts of cool air from open doors or from hot air blowing from furnaces. Many plants will suffer from this.

Light

Give your plants as much light as you can. That south window that burns everything in summer will give just enough light in the early months of the year. You may need to move some of the plants you keep in other areas to a brighter window. Plants like ferns, figs or philodendrons may want to be in that brighter spot. But be aware of how cool it is. You may have to move your plant back away from the glass

Humidity

dscn6545 (1)Most homes in winter are too dry for most houseplants and this is why we see them suffer by dropping leaves. To increase humidity, you can mist the plant, give it a shower (at room temperature – this also will dust for you!), or set in a saucer with rocks (elevate so the pot and roots are not constantly wet). Placing plants in kitchens or bathrooms where there tends to be more humidity is another idea. Plants that like it humid include ferns, palms, dieffenbachia and dracaena.

Fertilizing in the winter months when plants often rest is not recommended, however if your plant is actively growing with new sprouts, use a weak solution of water soluble fertilizer (20-20-20) once or twice a month.

It is also very important to have a good look at your houseplants on a regular basis. Besides removing spent leaves or flowers, watch for chewed leaves, spidery webs, or wet patches on leaves which can indicate pests. If you spot something, isolate the plant to avoid the pest migrating to the rest of your collection. Pick off the infested leaves, give the plant a good shower or gently wash the leaves with water or safers soap and get a good insecticide. Take your sick plant to the bath tub for a good spray. Remember to spray the soil as well as the plant as many pests lay their eggs in the soil. You can also use plant pest strips. These work very well for fungus gnats and other flying pests.

With a little attention and care over these stressful months, you can keep you houseplants happy and healthy and ready for the next season.

Winter Gardening

By Judy Bernard, Master Gardener

My jade plant is getting too large for my pot again! The last time it got too big, I tried potting it up into a larger pot, but it was too unwieldy and so I just cut off a few branches and potted them up in some new potting soil. Three years later, its  already over 50cm tall and wide, but stable in the pot. So, I’m just going to prune it and tidy it up.

And this is where my winter gardening comes in. Those pieces I’ve pruned are going to be potted up for new plants which I can give away or put into a plant sale. Just remember, they are succulents and therefore don’t need a lot of water.judys jade plant

It’s also a good time to clean up those miniature gardens that come from the supermarket or from the florist with several plants in the container. The plants can be removed and repotted individually, giving their roots more room to grow and allowing you to individualize their care.

Other winter gardening includes checking the tender bulbs and tubers that were dug up last fall for disease and rot and removing anything not healthy. They may also need a little moisture added to keep them from drying out but not enough to stimulate growth.

Have fun with your plants.

The Magnificent Hoya Plant

by Mary Jane Parker, Master Gardener

I have a huge Hoya (Hoya carnosa) plant in my office. Also known as the wax plant or porcelain plant they are an incredibly long lived plant because the one I have has been with me for close to 30 years and it was supposedly at least 30 years old at that time. My hoya is probably the most common variety in cultivation – Hoya carnosa, native to tropical countries such as India, Japan, and Taiwan, but there are between 200 and 300 species in this family Apocynaceae (subfamily Asclepiadoideae) worldwide.

Hoyas are vines that climb by twining around structures, supports or trees outside in their native countries through the use of adventitious roots. They have simple leaves, arranged in an opposite pattern and mine has shiny leaves flecked with tiny silvery spots.

Hoyas require bright light to flower. My hoya flowers in spring and early summer and when it does flower, the scent is awesome and capable of perfuming a whole room. The flowers are star shaped, very light pink and produce abundant sticky nectar which can be a mess. Flowers are formed on spurs which get longer every year. Some of the spurs on my hoya has are at least 2 inches long.

hoyabellablossom

Hoya carnosa has exhibited something called Crassulacean Acid Metabolism (CAM). As I understand it, CAM is the function that allows plants to store water for periods of time to use when there is none or very little for their basic functions. Like cacti in the desert – cool stuff!

Besides being an attractive houseplant, some Polynesian cultures use hoyas medicinally. Recent studies at the University of Georgia have also shown that Hoya carnosa is a good buffer against indoor pollutants. Another reason to love this plant!
