Bringing Spring In: Forcing Bulbs Indoors

Friday, January 13th, 2012

While our North State Gardens have not had much of a winter just yet, one of winter’s particular pleasures is that of bringing spring in. Having bright, fragrant spring bulbs or dramatic branches of spring flowering trees and shrubs bloom inside our homes during the cold dark winter months does just this. This technique – commonly referred to as forcing – is one of the gardener’s great tricks for getting through the winter with minimal garden-variety seasonal affective disorder.

The history of forcing plants to grow and produce out of their normal seasons dates back to the Roman Empire when records show that cucumbers were grown in a winter greenhouse for the Emperor. The forcing of bulbs out of season for their ornamental flowers is recorded at least as early as the mid-1700s.

Paperwhite Narcissus (Narcissus tazetta “Paper White”) and Amaryllis are readily available in shops and catalogues from early fall through Christmas, but why stop the fun there? You can force all kinds of bulbs from October all the way till whenever real spring arrives in your garden. Furthermore, forcing bulbs is a technique that allows you to see the whole – normally hidden in the dirt - life cycle of these plants – from shriveled brown orb, to a pale green nub letting you know they are alive, to a miraculous flower on your kitchen windowsill in mid-winter.

The trick to forcing bulbs lies in trying to mimic their normal outdoor season. The hardier a bulb is outdoors, or the later it is supposed to bloom, the longer you need to cool it while it is rooting.

Warm-climate natives Amaryllis and paperwhite Narcissus are easy to force indoors. Place the bulbs, pointy side up in a vase or bowl that will allow their rooting bottoms to sit just over or in water, you can nestle them in pebbles with water, or actually pot them up in just enough soil to surround an cover the bulb itself. Once placed in their growing medium, and positioned in a bright, warm place in your home, these bulbs will generally bloom in 4 - 8 weeks – paperwhites bloom more quickly than amaryllis.

These two bulbs are fairly fool-proof, you might consider taking on some more challenging varieties. The satisfaction of getting a small bunch of snowdrops or grape hyacinth to bloom indoors is fun.

For hyacinths, iris, snowdrops, tulips, and Narcissus other than paperwhites, a cooling period is necessary in order to get the bulb to bloom. The general rule of thumb is to cool your bulbs for forcing 10 to 18 weeks at 50 degrees or less (see below for a reference guide to a few kinds of bulbs). One way to do this, is to pot your bulbs up in unfertilized soil, water well and put them in a refrigerator for 8 to 18 weeks. Check on them every now and then to see if they need a little more water, but for the most part they need very little while they are cooling and rooting. Once you see roots popping out the bottom of the pots, or the green shoot of the plant above the soil a fair bit, then pull them out of their dark cooling place and set them in a sunny window to grow the rest of the way. Once they are out of cooling, they will need light, and water when the soil is dry.

When your forced bulbs are done blooming, if they are hardy in your gardening zone, you can plant them outdoors as soon as the ground is workable (in the warmer portions of the North State, this is all winter). Due to being depleted by forcing, your bulbs may not bloom for the first one or two seasons in the ground. For the best performance, plant with bulb specific fertilizer and water in well - especially during dry conditions.

Writing recently in the Chico Enterprise-Record, Butte County Master Gardener and Paradise Garden Club member, Carolyn Melf noted:”…a major problem with paperwhites is their tendency to develop long, lanky stems and leaves that require support. But there is a solution to this problem.
Researchers at Cornell University have discovered how to reduce the growth of the leaves and stems by one-third, while still producing normal-sized flowers, simply by watering with isospropyl (rubbing) alcohol. Steps to stunt paperwhites with rubbing alcohol
1. Place the bulbs, pointed side up, in about 3 inches of pebbles. Push the bulbs down, leaving half of each bulb exposed. Add water to barely touch the bottom of the bulbs, and wait one week.
2. When shoots reach 1″-2″ above the top of the bulb, pour off the water.
3. Replace the water with a 5 percent solution (one part rubbing alcohol to 10 parts of water).
4. Continue to use the alcohol solution for all future watering. You will see results in just a few days.”

Cooling Period guide for forcing selected bulbs, from The Brooklyn Botanic Garden Gardener’s Desk Reference, Henry Holt and Company, Inc. (1998):

Crocus: 15-week cold treatment; cover completely in potting soil.

Daffodil (which are Narcissus other than paperwhites): 16-17-week cold period; plant bulbs with top 1/3 out of the soil.

Tulip: 15-16-week cold period; plant bulbs with top 1/3 out of the soil.

Grape Hyacinth (Muscari): 15-week cold period; cover completely in potting soil.

Fritillaria: 13-15-week cold period; plant bulbs with top 1/3 out of the soil.

Iris: 15-week cold period; plant bulbs with top 1/3 out of the soil.

Snowdrop: 15-week cold treatment; cover completely in potting soil.

Good Resources for Bulbs:

Most independent nurseries sell a wide variety of spring bulbs, those with some still in stock may have them on good discounts beginning right after New Years. If their gift shop is unheated, even the unusual bulbs may well be pre-chilled for you.

Also try the following mail-order sources - often if you place your fall order in early summer- before July 1, these sources offer early-bird discounts:

Old House Gardens: both the catalogue and staff are so very helpful with all things bulb. They even sell a reproduction hyacinth glass, hand-blown by a glass works on Cape Cod and based on a New England design from the Victorian era.

And finally, while I have not yet tried forcing any native bulb varieties, Telos Bulbs has an excellent California native bulb selection.

What’s in a Name? & the June Calendar of Regional Gardening Events

Thursday, May 27th, 2010

Over the past few weeks I have had several in-depth conversations about plant names. Specifically, why I chose to include scientific plant names across the front of Jewellgarden’s new note cards and how these names are determined - why are they so confusing? All of these conversations got me thinking about plant names - what purpose they serve, why it is important to me to learn them and thus why they proudly embellishing my new cards.

March 2009 in the Garden & Monthly Calendar of Regional Gardening Events

Wednesday, February 25th, 2009

Every year – about this time in the North Valley - the big spring bloom begins. And every year I think – it’s even more miraculous – even more lovely this year. Narcissus, hellebores, daphnes, camellias, magnolias, the first of the fruit trees – the beauty is abundant. And now that we’ve had some real rain and snow, I can actually enjoy the bloom with less worry. Close to 11 inches of rain – that’s how much rain I measured in my home garden in the month of February. The rain was so inspiring to me that some days I had to go check my rain gauge 2 or 3 times. I then ran inside, reported the newest numbers to my family and rushed to record the numbers in my journal. I know one good month of rain and snow will not reverse the past seasons’ unusually low precipitation. I know we are still in a drought – but this one good month sure doesn’t hurt. And when the March mountains are decked with snow and the valley is greening and damp, life in my garden feels just right. Photo: White Hellebores.

Although the first official day of spring is March 20th – hurray! - average last frost dates are still a ways away for most of us (early-April for the earliest of us) so don’t get too excited too quickly. Now is a great time for continuing to sow cold hardy vegetable seeds or planting out cold hardy perennials and shrubs to begin establishing before true spring. Now is also the time for feeding a balanced fertilizer to your trees, shrubs and lawns that are starting to show signs of growth. March 1st is a traditional date on which to feed citrus trees. And don’t forget that March 8th, we spring our clocks forward one hour. Photo: Looking across snow covered mountains from Mt. Shasta in mid- February.

November 2008 In the Garden

Friday, October 31st, 2008

Life is good. Really. November in the Northstate Garden sums up everything I love about living and gardening here – rich colors, abundant flowers and edibles, perfect weather – yes, even the rain - and nice people. After this past season of fire, economic chaos and seemingly endless politics – November in the Northstate is nothing short of a miracle.

On a crisp November morning, stand with a warming sun shining down upon you –in the middle of the Sundial Bridge in Redding watch the anglers and school children indulging in the beauty of one of our mighty rivers. Walk through the dappled sunlight beneath the sheltering trees of Chico’s Bidwell Park bikers and morning parents with children going this way and that. Walk the Feather River Fish Ladder in Oroville to see the salmon and steelhead struggling to make their way home. Hike Mount Lassen or the Trinity Alps. Take the drive to Lake Almanor. The greater Northstate Garden is one of the best inspirations by far for our own Northstate Garden.

In my garden – the leaves are beginning to change, some further gone than others. Persimmons hang fat and iridescent on the branches – sweetening up with the cool nights. I am cutting back the dead and the spent, top-dressing my beds with compost mulch. Some of the compost is from my own compost bin and spreading that always feels satisfyingly self-sufficient. Some people are sad at this particular cutting back of the year, but for me it feels freeing, things have gotten a bit overgrown and it’s time. And while we Northstate gardeners get to enjoy all four seasons we also get to enjoy the fact that while some things are now entering winter dormancy, others are just breaking their summer dormancy. Don’t be too quick to cut back plants that are still actively flowering – on these cold-morning/warm afternoons days the pollinating bees, butterflies moths and hummingbirds are still very active and they will reward your patience.

George Winter – Wyntour Gardens - Redding; Red Bluff Garden Center – Red Bluff

Friday, August 29th, 2008

George Winter is a soft-spoken man with a large presence. “When he speaks, people listen,” one of his long-time staff, Sherry Rosen, said to me when the three of us met to walk through Wyntour Gardens in Redding earlier this summer. And for good reason, George Winter has been one of the most knowledgeable, smiling and constant faces of the Northstate gardening world for the past 30-plus years.

George grew up on a dairy farm in Gridley and his father went into the nursery business later in his life. After graduating with an Industrial Education degree from CSU Chico, George thought he would like to be a teacher. It didn’t take him long to realize that the nursery business was his calling: “I thought the kids were going to eat me alive,” he recalls laughing.

When his father was ready to retire in the 1970s, Winter took over the family business, the Red Bluff Garden Center, and when the opportunity arose for a second nursery, he jumped at the chance. On April 4, 1992, he opened Wyntour Gardens in Redding, on Airport Road near the Redding Municipal Airport. Every April Wyntour Gardens holds an Anniversary Event in celebration.

Winter attributes the success of the two nurseries to a couple of things – most importantly, his excellent staff who “love what they do and are knowledgeable about it,” and he has always made it a point to provide the best plants possible for our region.

In time he realized that one of the best ways to provide the best plants was to grow them himself. In the early 2000s, Winter started the wholesale propagators, North Valley Growers, based out of the Red Bluff Garden Center and managed by longtime horticulturist Jeff Brooks. Besides supplying plants to Wyntour Gardens and the Red Bluff Garden Center, plants with the North Valley Growers’ tag can be found at nurseries up and down the valley. And, in part on principle, plants from other local growers can be found at Wyntour Gardens and Red Bluff Garden Center.

“Plants that are grown locally are acclimated to our climate and soils, they travel less, need less packaging and ultimately are better, more successful plants that cost less for the nurseries and the customer,” explains Winter. “Growing plants ourselves allows us to more easily and swiftly follow plant trends, or help to inspire those plants trends – for instance by getting more varieties of drought tolerant or native plants into the industry.”

That impulse to inspire and lead the way in horticultural trends does not stop with the plant propagation, it is what led Winter to make both of his nurseries part of the Master Nursery association, to carry the widest possible selection of organic and sustainable plant and soil fertilizers and amendments, and to re-use or recycle all plastic nursery pots. Wyntour Gardens also boasts one of the largest selections of glazed pottery you will find in the Northstate.

George and his wife Carol are both avid gardeners at their home in the foothills of Redding. “We started with bare ground, nothing but brush!” George tells me. Carol designed the landscape (which includes several different gardens). They terraced the grounds and developed and installed an irrigation system. Last Fall they planted over 1500
narcissus bulbs on their hillsides “which were just spectacular this past spring!”

While having successfully been in business for more than 30 years, Winter still has goals for Wyntour Gardens: “I would like to improve our water gardening and pond plant selections, I want to see our events and classes continue to expand – and to work toward even more focus and clarity,” he says. “Customers are what make our nurseries great and I am honored to have served some local families for several generations now,” Winter continues. In order to better serve those customers, in the past few years, Winter has developed easy to use websites for both nurseries, on-line newsletter subscription services, and free monthly classes at both sites so that gardeners can learn and engage in the life and community of the nurseries.

While soft-spoken, Winter is a born communicator. In the past he has done a Garden Spot for the Channel 7 news, he regularly contributes to InsideOut magazine, and he writes a column for both nurseries’ websites entitled George’s Almanac. For more information about events, classes or newsletters from Wyntour Gardens or the Red Bluff Garden Center, visit their websites: www.wyntourgardens.com and www.redbluffgardencenter.com. Both the real and on-line nurseries are worth a visit.

Julie Nelson: Narcissus in the Northstate - Redding

Saturday, June 28th, 2008

Due to the ongoing wildfire coverage, this week’s In a Northstate Garden is a repeat from earlier this season. We will return to our regular on-going programming the weekend of July 5th and 6th.

img_8211.jpgJulie Nelson has a jones for daffodils, and so she told me in our first correspondence about her garden northeast of Redding. Over the years, she and her husband, Jim, and sons, Paul and Soren, have planted some thousands of Narcissus of all kinds in their garden. (Photo at left: Soren, Julie, Jim and French-exchange student Florian, who is living with the Nelsons this year.) The bulbs start blooming before Christmas (the early tazetta type Narcissus such as Paper Whites) and finish in April. Julie and Jim are both professional botanists – she works full-time for the Shasta-Trinity National Forest. As a family the Nelson’s are engaging and thoughtful: they like to discuss politics, the natural history of our region, Garrison Keillor and good food. They name roosters for head’s of state and using plays on words. They are as warm and easy-going as the Narcissus genus - and the home garden - they so clearly love. (Although Paul, the elder brother, now lives in an apartment in the city and it makes Julie wonder if she did not make him dig one too many holes for bulbs.)

img_7448.jpgThe Nelsons moved to their several acres of blue oak woodland in 1989 and created their garden on the red dirt left over from the construction of the house. “My garden consists of anything that thrives in this challenging climate–lots of Mediterranean things, lots of natives, bulbs, old shrub roses, and volunteers,” she told me. The whole garden – including large chicken run, enclosed vegetable garden, mixed borders of perennials and shrubs, and lemon and pomegranate trees closer to the house - is nice. But visiting in spring, it is easy to see that not only the sheer number of Narcissus but also their generous and deft placement in the landscape, is outstanding.
