Pot amaryllis snugly with the top third of the bulb above the soil, and grow paperwhites in gravel and water or well-draining potting mix. A greenhouse from BC Greenhouse Builders makes forcing easier, with more natural light for sturdier stems, cooler nights that help blooms last longer, and bench space to stagger plantings for color from December into February. **Jump to a Section:** - [What does it mean to "force" bulbs?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#forcing-bulbs) - [Why is a greenhouse a great place to force holiday bulbs?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#greenhouse-forcing-bulbs) - [When should you plant amaryllis and paperwhites for holiday blooms?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#when-to-plant-holiday-bulbs) - [How do you choose healthy bulbs for forcing?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#choosing-healthy-bulbs) - [How do you plant and force amaryllis in a greenhouse?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#force-amaryllis) - [How do you force paperwhites in water or soil?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#force-paperwhites) - [What greenhouse conditions keep holiday blooms looking their best?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#greenhouse-conditions-holiday-blooms) - [What are the most common problems when forcing bulbs?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#forcing-bulbs-problems) - [How can your greenhouse brighten the darkest months of the year?](https://blog.bcgreenhouses.com/forcing-amaryllis-and-paperwhites-a-guide-for-holiday-blooms-in-greenhouses#greenhouse-winter-blooms) By late fall, the garden outside starts to look a little grey and tired. Inside the greenhouse, it doesn't have to. With a few bulbs, some pots, and a bit of planning, you can have bold red amaryllis and clusters of white paperwhites blooming right in time for the holidays. Amaryllis and paperwhites are two of the easiest bulbs to grow out of season because neither one needs a long cold period before it flowers. Plant them now, give them light and steady temperatures, and they will reward you with weeks of color during the darkest stretch of the year. A greenhouse makes the process even easier, with more natural light than a windowsill, cooler nights that keep stems strong, and plenty of bench space to plant in waves. ![amaryllis](https://blog.bcgreenhouses.com/hs-fs/hubfs/amaryllis.png?width=1200&name=amaryllis.png "amaryllis")   ## What does it mean to "force" bulbs? Forcing is a gardener's term for encouraging a bulb to bloom outside of its natural season. Instead of waiting for spring, you control the light, temperature, and water so the bulb flowers when you want it to.  ### How forcing differs from natural blooming Most spring bulbs, like tulips and hyacinths, need several weeks of cold before they will flower. That chilling period mimics winter and tells the bulb it is time to grow. Forcing those bulbs takes extra steps, like storing them in a fridge for 12 weeks or more. ### Why amaryllis and paperwhites are the easiest to start with Amaryllis and paperwhites come from warmer climates, so they skip the chilling step entirely. Once planted and watered, they start growing right away. That makes them a perfect first forcing project and a reliable favorite for experienced growers who want holiday color without a lot of fuss. - ![bulbs](https://blog.bcgreenhouses.com/hs-fs/hubfs/Gardening/bulbs.jpg?width=259&height=194&name=bulbs.jpg) - ![paperwhites](https://blog.bcgreenhouses.com/hs-fs/hubfs/paperwhites.png?width=1200&height=630&name=paperwhites.png) ## Why is a greenhouse a great place to force holiday bulbs? You can force bulbs on a sunny windowsill, but a greenhouse gives you a few real advantages. - **More light, sturdier stems.** Bulbs grown in low light stretch toward the window and often flop over. - **Cooler nights, longer blooms.** Most homes stay warm day and night. A greenhouse that cools down in the evening slows the flowers down, and so they last longer once they open. - **Room to grow in waves.** Bench space makes it easy to plant a few pots every couple of weeks for steady color well into winter. ### A quick note on cold nights Neither bulb is frost hardy. Keep nighttime temperatures above about  50° F or 10° C, and keep pots away from glazing on the coldest nights, since glass and polycarbonate cool faster than the air around them. If your greenhouse is unheated, a [small heater](https://shop.charleysgreenhouses.com/collections/temperature-management) on a thermostat can keep things steady, or you can start bulbs in the house and move them out once they are actively growing and the forecast cooperates. ## When should you plant amaryllis and paperwhites for holiday blooms? Timing is the part that trips up most growers. The good news is that it is easy to plan once you know how long each bulb takes. ### How long does each bulb take to bloom? - **Amaryllis:** about 6 to 10 weeks from planting to flowering - **Paperwhites:** about 4 to 6 weeks from planting to flowering Warmer conditions speed things up, while cooler conditions slow them down. A greenhouse lets you nudge that timing a little in either direction. ### How do you count back from your target date? Pick the date you want blooms, then work backwards. | **Target bloom date** | **Plant Amaryllis** | **Plant Paperwhites** | | --- | --- | --- | | Mid-December | Late October to early November | Early November | | Christmas | Early to mid-November | Mid-November | | New Year's | Mid to late November | Late November to early December | | Late January | Late November to December | Mid-December | ### How can you keep color going all winter? Stagger your planting. Pot up a few bulbs every two weeks from late October through December, and you will have fresh flowers opening from the holidays into February. ![Amaryllis growing over time](https://blog.bcgreenhouses.com/hs-fs/hubfs/paperwhites%20(1).png?width=1200&name=paperwhites%20(1).png "Amaryllis growing over time")   ### Can you grow forced bulbs as holiday gifts? Absolutely! A potted amaryllis just starting to show buds makes a thoughtful gift for hosts, neighbors, and teachers. Plant a few extra pots in early November, and they will be ready to wrap by mid-December. Just keep in mind that both plants are toxic to cats and dogs, so it is worth adding a quick note for anyone with pets. ## How do you choose healthy bulbs for forcing? A strong bloom starts with a healthy bulb. When you are shopping, look for: - **Firm, heavy bulbs**with no soft spots, mold, or shriveling - **Larger amaryllis bulbs,** which often produce two or more flower stalks - **Plump paperwhite bulbs** with dry, papery skins Buy early if you can. The best selection tends to sell out by November, and bulbs that sit in warm stores too long can start sprouting before you get them home. ## How do you plant and force amaryllis in a greenhouse? Amaryllis is about as close to foolproof as forcing gets. A few simple steps set it up for success. ### What pot and soil should you use? Choose a sturdy pot that is only about 1 to 2 inches or 2.5 to 5 cm wider than the bulb. Amaryllis likes a snug fit, and a heavy pot helps balance the tall flower stalks. Use a well-draining potting mix and plant bulbs so the top third sits above the soil line. ![amaryllis bulb in white planter pot](https://blog.bcgreenhouses.com/hs-fs/hubfs/paperwhites%20(2).png?width=1200&name=paperwhites%20(2).png "amaryllis bulb in white planter pot")   ### How much should you water at first? Water thoroughly once after planting, then hold back. Until you see new growth, water only when the top of the soil feels dry. Too much water before roots are active is the most common cause of bulb rot. ### What temperature and light does amaryllis need? To get roots and shoots moving, aim for warmer temperatures of around 68 to 75° F, or 20 to 24° C, and bright light. Once buds form and start showing color, cooler temperatures of 60 to 65° F, or 16 to 18° C, will help the flowers last longer. ### Should you rotate or take amaryllis stems? Turn the pot a quarter turn every few days so the stalk grows straight instead of leaning toward the light. Tall varieties or heavy double blooms may need a slim stake for support, especially once the flowers open. ## How do you force paperwhites in water or soil? Paperwhites are fast, forgiving, and can grow in just a dish of pebbles and water. ### How does the gravel and water method work? Fill a shallow bowl or container with a few inches of gravel, pebbles, or glass beads. Nestle the bulbs in, pointed end up, close enough that they almost touch. Add water until it sits just below the base of the bulbs. The roots will reach down into the water, but the bulb itself should stay dry to prevent rot. Check the water level every few days and top it up as needed. ![paperwhite bulbs in pebbles](https://blog.bcgreenhouses.com/hs-fs/hubfs/paperwhites%20(3).png?width=1200&name=paperwhites%20(3).png "paperwhite bulbs in pebbles")   ### Can you grow paperwhites in potting soil? Yes! Plant them shoulder to shoulder in a pot of well-draining mix with the tops showing, water well, and keep the soil lightly moist. Soil gives the roots more to grip, which can help taller stems stay upright. ### How do you keep paperwhites from flopping over? Paperwhites are known for growing tall and tipping over just as they bloom. Bright light and cool temperatures help a lot, and a greenhouse gives you both. You can also try a [trick tested by researchers at Cornell University](https://news.cornell.edu/stories/2006/03/tipsy-flowers-dont-tip-over-cornell-research-shows): once roots have formed and shoots are about 1 to 2 inches (2.5 to 5 cm) tall, swap the plain water for a mix of about one part clear spirits (like vodka or gin) to seven parts water. This slows stem growth without affecting the flowers, so your blooms end up shorter and sturdier. ### What should you know about paperwhite fragrance? Paperwhites have a strong scent. Some people LOVE IT, and others find it a little musky. That is one more reason a greenhouse is a nice home for them. You can enjoy the blooms without the fragrance filling your living room.  ## What greenhouse conditions keep holiday blooms looking their best? Once your bulbs are growing, steady conditions will help them bloom well and last longer. ![Kelly Hopkins - Image 29](https://blog.bcgreenhouses.com/hs-fs/hubfs/Kelly%20Hopkins%20-%20Image%2029.jpg?width=2000&height=1500&name=Kelly%20Hopkins%20-%20Image%2029.jpg "Kelly Hopkins - Image 29") ### Temperature Warmer temperatures help bulbs get started, while cooler temperatures keep flowers fresh once they open. Aim for daytime temperatures of around 65 to 70° F, or 18 to 21° C, and night temperatures a few degrees cooler, but not below 50° F/10° C. ### Light Give both bulbs as much light as possible, especially through short winter days. If your greenhouse has twinwall or fivewall polycarbonate, the diffused light helps prevent hot spots while keeping plants bright. Low-E double pane glass lets in clear, strong light with better insulation for cold nights.  ### Airflow and humidity Closed winter greenhouses can trap moisture, and damp air around bulbs can lead to mold or rot. A small circulating fan keeps air moving and helps the soil surface dry between watering.

Move pots into the house once the first flower starts to open, so you can enjoy them where you spend the most time. Place them in the coolest bright spot you have, away from heat vents and the fireplace. Cooler rooms help amaryllis blooms last two to three weeks. ## What are the most common problems when forcing bulbs? Most forcing issues come down to light, water, or temperature. Here is how to spot and fix them. | **Problem** | **Cause** | **Solution** | | --- | --- | --- | | Tall, leggy, or floppy stems | Low light or temperatures that are too warm. | Move pots to the brightest spot in the greenhouse and keep nights cooler. | | Buds that dry up before opening | Often called bud blast, this can happen when bulbs dry out or face sudden temperature swings | Keep watering consistent once growth begins and avoid placing pots near heaters or drafty doors. | | Soft, mushy bulbs | A sign of rot from too much water. | Water sparingly until growth appears, and make sure paperwhite bulbs sit above the waterline. | | Leaves but no flowers | The bulbs may have been too small or depleted from a previous season | Starting with large, healthy bulbs is the best way to avoid this. | ## How can your greenhouse brighten the darkest months of the year? A greenhouse is not only for tomatoes and seed starting. Forcing holiday bulbs is a simple way to keep your space productive and beautiful when the garden outside is resting, and to share a little color with the people around you. With bright light, steady temperatures, and good airflow, a BC Greenhouse gives bulbs the conditions they need to bloom right on time. Start a few pots this month, plant a few more in a couple of weeks, and enjoy fresh flowers all the way into the new year. ![BC Greenhouse with christmas tree inside](https://blog.bcgreenhouses.com/hs-fs/hubfs/Greenhouse%20Exterior/315539557_6341807555834889_5185007723293775224_n.jpg?width=960&name=315539557_6341807555834889_5185007723293775224_n.jpg "BC Greenhouse with christmas tree inside")   ## Related/Recent Blogs #### [![](https://blog.bcgreenhouses.com/hs-fs/hubfs/paperwhites%20(3).png?width=350&name=paperwhites%20(3).png) by Hannah Nicklas | 10.21.2026 | 20 min Forcing Amaryllis and Paperwhites: A Guide for Holiday Blooms in Greenhouses Quick Answer To force amaryllis and paperwhites for the holidays, plant amaryllis 6 to 10 weeks and paperwhites 4 to 6 weeks before your target bloom date, then give them bright light and steady tempe...
