Amaryllis Care Guide — Canada
Amaryllis care in a Canadian home, from the gift bulb in December to flowers again next Christmas — with the summer outdoors and the rest period worked out for your city.
Amaryllis care in Canada starts with a bulb that has already done most of the work. The flower you get this winter was formed inside the bulb last year, so a healthy gift bulb flowers almost whatever you do. Next year’s flower is a different matter: it depends on what you do with the leaves after this one fades, and in Canada that means a short summer outdoors and a rest that has to start before the first frost.
The plant is Hippeastrum, from South America — not the true Amaryllis of South Africa, though everyone, including the garden centres, calls it amaryllis. It is a tender bulb: no frost, ever.
At a glance: pot it with the top third of the bulb above the mix, water once and then sparingly until it grows; it flowers in about 6–8 weeks. After flowering, cut the stalk but keep the leaves. Summer it outdoors between your last and first frost. For Christmas flowers again, start a cool, dry rest of 8–10 weeks between August 21 and September 18. Toxic to cats and dogs.
Is your Amaryllis getting enough light this winter?
A Canadian winter cuts daylight roughly in half. See what your city actually gets this month, and whether a grow light is needed.
Potting a Gift Bulb
Choose a heavy pot only a few centimetres wider than the bulb, with a drainage hole. Amaryllis flowers well when it is snug, and a tall stem with three or four big flowers on it tips a light plastic pot over. Ordinary potting mix is fine. Set the bulb so that at least the top third sits above the surface, firm the mix around it, and water once.
Then hold back. A bulb with no leaves uses almost no water, and a wet one sitting in cold mix rots from the base. Water again when you see the flower stalk or the first leaves pushing up, and from then on whenever the top of the mix is dry.
Getting it home in December
A potted amaryllis in bud is a tender tropical plant, and a Canadian parking lot in December is well below anything it tolerates. Have it wrapped, warm the car first, and make it the last stop. A dry, unpotted bulb in its box is much tougher than a plant in growth.
Bright, Cool and Turned
Give it the brightest window you have. A Canadian December day is short, and in dim light the stalk stretches toward the glass and leans. Turn the pot a quarter turn every day or two so the stalk grows straight. Once the flowers open, a cooler spot away from heat registers makes them last noticeably longer; a warm room speeds everything up and shortens the show.
A tall stalk with three or four open flowers is top-heavy. A thin stake pushed into the mix beside the bulb, not through it, saves it from snapping.
After It Flowers: Keep Every Leaf
When the last flower fades, cut the stalk off a few centimetres above the bulb. Leave the leaves alone. They are what rebuilds the bulb, and next year’s flower depends on how many of them the plant keeps, and for how long, in good light. Keep it in the brightest window, water when the top of the mix is dry, and feed it with a general houseplant fertilizer while it is in growth.
The Summer Outdoors, by City
The easiest way to rebuild an amaryllis bulb is a summer outside. Move it out once frost is behind you, into a spot with morning sun and some afternoon shade, and bring it back in before the first frost. How long that window is depends almost entirely on where you live:
| City | Out after (last frost) | In before (first frost) | Frost-free days |
|---|---|---|---|
| Victoria | Mar 10 | Dec 15 | 280 |
| Vancouver | Mar 15 | Nov 30 | 260 |
| Toronto | Apr 20 | Nov 1 | 195 |
| Windsor | Apr 20 | Oct 28 | 191 |
| Halifax | May 10 | Oct 18 | 161 |
| Ottawa | May 9 | Oct 12 | 156 |
| Montreal | May 9 | Oct 7 | 151 |
| Quebec City | May 17 | Sep 28 | 134 |
| Edmonton | May 14 | Sep 23 | 132 |
| Calgary | May 23 | Sep 21 | 121 |
| Winnipeg | May 25 | Sep 20 | 118 |
| Saskatoon | May 25 | Sep 12 | 110 |
Average last and first frost dates are Environment and Climate Change Canada climate normals, the same data behind every frost date on this site. An average last frost is the earliest sensible day to move it out, not a safe one — waiting another week or two, until nights stay mild, costs nothing. Not on the list? Look up your city.
How to Make It Bloom Again for Christmas
An amaryllis reblooms after a rest. Stop watering, let the leaves yellow and die back, then keep the dry bulb, still in its pot, somewhere cool and dark — a basement or a cold room — for about 8 to 10 weeks. Published advice ranges from 6 to 12 weeks; the middle of that range is the safe choice. Then bring it into warmth, scrape off the top couple of centimetres of mix and replace it with fresh, water once, and it flowers about 6 to 8 weeks later.
Counted back from 25 December, that puts the start of the rest in late summer — which in Canada is the same few weeks you are deciding when to bring it in anyway:
| Stop watering and start the rest | August 21 to September 18 |
| Wake it: warmth, fresh mix, first water | by October 30 |
| Flowers | around Christmas |
Dates are counted from the rest and regrowth ranges above, not stored, so they are always for the coming Christmas. Bulbs vary; a few weeks either way is normal. In the short-season cities in the table, first frost can arrive before the end of that rest window — bring the plant in first and start the rest indoors.
Buy amaryllis by bulb size, not by the picture on the box: a bigger bulb holds more stored energy and usually sends up more flower stalks. Check that it is firm and heavy for its size, with no soft spots or mould at the base.

Waxed Amaryllis Bulbs
Wax-coated amaryllis bulbs sold without a pot need no soil and no water: the flower is already inside the bulb, and the wax only stops it drying out. They make an easy gift, but treat one as a single-season flower. With no roots it has no way to rebuild itself, and while you can peel off the wax and pot it up after it flowers, expect a year or more before it flowers again, if it does.
Pets: the ASPCA lists amaryllis as toxic to dogs, cats and horses. Pot the bulb rather than leaving it loose where a dog can chew it, and keep the plant out of reach. More in holiday plants and pets.
Frequently Asked Questions
How do I plant an amaryllis bulb?
Use a heavy pot only a few centimetres wider than the bulb, with a drainage hole, and ordinary potting mix. Set the bulb so at least the top third sits above the mix, firm it in, and water once. Then water sparingly until you see new growth, because a wet bulb with no leaves rots.
How long does an amaryllis take to bloom?
About 6 to 8 weeks from potting or from waking it after its rest, depending on the bulb and how warm and bright the room is. A cool room slows it down and makes the flowers last longer.
What do I do with an amaryllis after it flowers?
Cut off the flower stalk near the bulb once the flowers fade, but keep every leaf. The leaves rebuild the bulb for next year's flowers. Keep it in the brightest window you have, water when the top of the mix is dry, and feed it while it is growing.
Can I put my amaryllis outside in summer in Canada?
Yes, and it is the easiest way to rebuild the bulb. Move it out after your last frost, into morning sun, and bring it back in before your first frost. The window runs from about four months on the Prairies to eight or more on the south coast of BC.
How do I get my amaryllis to bloom again for Christmas?
Give it a rest. Stop watering and let the leaves die back, then keep the bulb cool and dry for about 8 to 10 weeks. Wake it with fresh mix, warmth and a first watering about 8 weeks before you want flowers. For Christmas that means starting the rest between August 21 and September 18.
Can a waxed amaryllis bulb rebloom?
Usually not, and it is best treated as a one-season flower. A wax-coated bulb flowers on the energy it already holds, with no pot and no water, but it has no roots and no way to rebuild itself. If you want to keep it, peel off the wax and base after flowering and pot it up, but expect it to need a year or two before it flowers again, if it does.
Is amaryllis poisonous to cats and dogs?
Yes. The ASPCA lists amaryllis as toxic to dogs, cats and horses. Pot it up rather than leaving a loose bulb where a dog can chew it, and keep the plant out of reach of pets.
Why is my amaryllis all leaves and no flowers?
Usually the bulb did not rebuild enough the summer before, because the leaves were cut off or it spent the summer in a dim room, or it never got a proper rest. Give it a full summer of leaves in good light, then a real cool, dry rest of at least 8 weeks.
