Growing Narcissus Bulbs

Growing Narcissus Bulbs

Growing Narcissus BulbsFor early flowering, pre-cooled bulbs (double nosed I, II and III are generally used for forcing) are purchased, these having been given four days of heat at 33°C (93°F), followed by 17.2°C (63°F) for one or two weeks, then cool stored at 7.2°C (45°F) until planting. Bulbs for later flowering are given 17.2°C (63°F) till the flower is complete in the bulb, then stored at 8.9°C (48°F). Variations in temperature treatment are also used to influence flower size.

Planting Narcissus bulbs in borders

Bulbs can be grown either directly in borders, or planted in boxes, bowls or pots. Any good soil with a pH of about 6 and a reasonable nutrient content will suffice. Planting direct into greenhouse borders is done in mid-autumn, in rows 15cm (6in) apart, the bulbs spaced 5-7.5cm (2-3in) apart in the rows. Water in well and cover with straw. Keep as cool as possible by ventilating for 6-7 weeks, then raise temperatures in steps of 2.6-5.5°C (5-10°F) to around 18.3°C (65°F). Keep bulbs well watered, about 75litre/m2 (15 gallons per sq yd) being necessary.

Planting Narcissus bulbs in boxes

Push the bulbs into deep 12.5-15cm (56in) boxes of clean soil which has not grown bulbs before, pH adjusted to 6.25, leaving the bulbs with their noses clear. Cover with a layer of sand or other material to act as a barrier between the soil or peat which will be used to cover them in a plunge out of doors to minimum depth of 15cm (6in). This is generally achieved in the first week of mid-autumn and adequate watering should be given to induce lower temperatures (by evaporation) down to about 7.2°C (45°F).
Boxes are brought into the greenhouse from the late autumn until late winter according to variety, when flowers are clear of the neck of the bulb and there is good root development, and not before (suppliers’ catalogues should always be consulted for housing dates). Minimum heat is given for 7-10 days, the temperature gradually being raised to 18.3°C (65°F). Water the boxes as necessary and make sure that they get all the light they need, otherwise the leaves will become gross. Support may be provided with netting or broken canes and string.
Bowls or pots of bulbs should be treated in the same way, strict attention being paid to watering and the amount of light given. Bulbs for later flowering should be left longer in the plunge and given lower temperatures in the greenhouse or home.

Forcing Narcissus bulbs under artificial light

This is carried out in the same way as described for tulips (below) although in general it is better to have higher light levels and lower temperatures 15.6°C (60°F), taking 4-6 weeks on average for the bulbs to flower.

Growing Tulip Bulbs

 

growing tulip bulbsA wide range of tulips is grown both for bowl culture and for cut flower production in boxes or greenhouse borders. The flowering times of a tulip and the ability to force it to flower early depends on a range of temperature treatments best left to the suppliers, as wrong treatment will result in the production of deformed flowers. In recent years specially prepared bulbs called 5° tulips have been used to a large extent for cut flower production in greenhouses.

5° tulips

Initially for two weeks the soil or growing medium must be kept cool, in the region of 10-12.8°C (50-55°F). 5° bulbs of a 12cm size are generally planted direct into greenhouse borders with a pH of 6.5 to 7 during the first week of late autumn in rows 15cm (6in) apart, the bulbs being 5cm (2in) apart, with the top of the bulb 1 cm (1/3in) below soil level. It is usual to grow in beds for easier management. After planting, the beds are thoroughly watered, not only to settle the soil but also to reduce temperature, but water-logging should be avoided. Heat is given after 2 weeks, up to 17.8°C (64°F) air temperature, and at this temperature flowering occurs. For later flowering a lower soil temperature, 10.6-11.1°C (51 — 52°F), is necessary for two weeks, then raise air temperature to about 15°C (50°F), a procedure which will keep flower quality high. Ventilation should, however, be given to avoid excess humidity and possible spread of botrytis.

Pre-cooled tulip bulbs

These are usually grown in boxes, the bulbs being planted in early October according to their size (generally 11-12cm or larger) from 6 x 11 (66) up to 13 x 7 (91). Boxes should be 7.5-10cm (3-4in) deep, clean and provided with adequate drainage. Soil should be of good texture with a pH of 6.5-7 and should not have been used for bulbs beforehand. Fill to within 2.5cm (tin) of the top and press the bulbs into the surface, adding more soil to leave the nose of the bulbs exposed. A layer of sand or ash is then put on top of the boxes to form a barrier between bulbs and plunge soil.
Boxes are then stacked in rows out of doors and covered with a layer of 15cm (6in) sand or peat, and straw on top of this. The watering of the straw subsequently induces the cool conditions necessary by evaporation. Fungal dusts (quintozene) are useful before the bulbs are covered by the soil.
After being in the plunge for a minimum period of 6 weeks, bulbs are brought into the greenhouse when the flower bud is clear of the neck of the bulb (as can be determined by examination) and there is good root growth, the temperature then being raised gradually to 21.1°C (70°F). They should be given shading by newspapers or other means to draw the flower up, or alternatively by putting them under benches. Temperatures are dropped as buds show colour.
Tulip bulbs can be brought into the greenhouse in succession to flower over a period, flowering commencing in early winter. It is important, however to pay attention to the programming provided by the supplier. Uncooled bulbs are given the same general treatment for flowering from mid-winter to early spring.

Pot culture

Bulbs being grown for pot display are generally of the more dwarf varieties of early singles and doubles. They are planted up closely and fairly firmly in pots or bowls of various sizes, either in bulb fibre or clean soil in mid-autumn with the nose of the bulb exposed. The bulbs may be plunged into a deep layer of soil or peat and put into a dark cupboard and after the necessary 6 week period brought into the greenhouse or a warm room where once again shade is essential to begin with. At all times where bulbs are being grown in boxes or pots, adequate water supplies should be maintained, but never to the extent of spotting the blooms by careless over-application. Gardeners frequently find that gross foliage and weak flowers result, this being due in the first case to an insufficiently cool rooting period, and latterly to excess temperatures applied too quickly.
There are many variations of tulip culture, including the use of mobile greenhouses, when the bulbs planted out of doors can be brought forward to flower earlier than the outdoor crop by covering in early spring.

Forcing tulip bulbs under artificial light

A very successful technique is the use of artificial light at 100W per sq yd and 30— 36cm (12-14in) above the top of the bulbs for 12 hours in each 24 at 18.3°C (65°F) to start with, dropping to 15.6°C (60°F) when buds show colour.   http://www.gardeninginfozone.com/growing-tulip-bulbs

How to Grow Tulips


Overview

When you see the tulips pushing through the ground, you know the long awaited spring has finally arrived. Tulips are probably the most popular of the spring bulb flowers. Their many types and varieties will leave you almost unable to make the choice of what bulbs to buy for your garden. Tulips come in early, mid and late season bulbs, so you can have the beautiful flowers around all spring and into early summer. With a little imagination, tulip beds can be one of the most interesting of all flower beds and they are easy to grow.

Step 1

Prepare the soil for your tulip bulbs by cultivating it down to about 10 inches. Work in some bulb fertilizer to the soil, and add compost and peat moss if your soil is very wet or heavy. Mounding the soil will also help with drainage. Spring bulbs like rich, well-drained soil, so even if your soil is sandy and drains well adding compost will be an advantage. For zones 3 to 7, choose a full sun to partially shaded area. In colder zones, choose a full sun area.


Step 2

Plant the bulbs 4 to 6 inches down with the pointed ends of the bulb pointing up in the late fall. Keep bulbs at least 6 inches apart. Read the bulb instructions on the depth as some varieties are planted deeper than others. Fill in the soil around the bulb.

Step 3

Moisten the soil when planting, and then not again for a couple of weeks while the bulb puts out its roots. Water when the top of the ground feels dry for 2 weeks.

Step 4

Mulch the area with about 4 inches of straw in very cold zones after the ground freezes. This will keep the soil moist and a little warmer during the winter months.

Step 5

Remove the mulch and fertilize the area when you start to see the flowers breaking through the soil. Use a 5-10-10 fertilizer and top dress the soil lightly. Repeat when the foliage begins to grow.

Step 6

Pinch the flowers as they start to dry, but leave the foliage until it is yellow and dead. The bulb will be getting its nutrition for the next year through the foliage, so you don't want to cut it off too soon.

Step 7

Dig the bulbs up when the foliage is dead. Be careful not to damage the bulb with your spade while digging. Clean the bulbs off, tear or cut the dead foliage, and store the bulbs in a dark, dry, well- ventilated area until next fall.

Dutch farmers tip-toe through the tulips as landscape is transformed into a spectacular display of colour

At first glance, it looks like a giant child armed with a box of crayons has been set loose upon the landscape.
Vivid stripes of purple, yellow, red, pink, orange and green make up a glorious technicolour patchwork.
Yet far from being a child's sketchbook, this is, in fact, the northern Netherlands in the middle of the tulip season.

With more than 10,000 hectares devoted to the cultivation of these delicate flowers, the Dutch landscape in May is a kaleidoscope of giddy colours as the tulips burst into life.
The bulbs were planted in late October and early November, and these colourful creations are now ready to be picked and sold as bunches of cut flowers in florists and supermarkets.
More than three billion tulips are grown each year and two-thirds of the vibrant blooms are exported, mostly to the U.S. and Germany.
In the first picture, an extraordinary 60 million tulips can be seen coming into flower.

Their dazzling colours are thanks to the years in the 17th century when Tulipmania swept the globe and the most eye-catching specimens changed hands for a small fortune.
But like a rainbow, this colourful landscape is a short-lived phenomenon.
When the flowers are gone, the land will be cultivated for a rather more mundane crop of vegetables.

DUTCH IRIS

 

Dutch iris are popular with florists, and home gardeners, because they are dependably pretty and easy to use. Long, strong, straight stems couple with blooms that are an ideal size for medium bouquets. The elegant blooms come in rich hues of blue, purple, yellow and white. These colors fit into any flower arrangement.

Few pleasures compare to having an abundant supply of fresh flower for cutting and using around your home. Garden grown blooms are also easy gifts for family, neighbours and friends.

Bulbs multiply each year for an ever-expanding show in beds, borders and cutting gardens.

Do yourself a favour and make sure to have plenty of future cut flowers by planting your
dutch iris now.

BEARDED IRIS

 


The bearded iris species is a remarkably resilient group of plants with few natural insect enemies or diseases. Bearded irises will grow with very minimal attention, however with a little attention and assistance they can become the center of attention in your garden.
Iris flowers are recognized by their three upright "standards" and the three lower segments named "falls". Thick bushy beards are found in the uppermost areas of each of the falls. This is the reason for the name bearded irises. There are different categories within the bearded iris group. They are basically divided by height as follows:
Miniature Dwarf Bearded (MDB) 2-8 inches in height
Standard Dwarf Bearded (SDB) 9-15 inches in height Intermediate Bearded (IB) 15-25 inches in height
Border Bearded (BB) 15-26 inches in height
Miniature Tall Bearded (MTB) 15-26 inches in height
Tall Bearded (TB) 27 plus inches in height.

The Tall Bearded irises are the most well known and popular category within this group. The other bearded iris categories provide great
interest in that they flower in the month prior to the tall bearded. This extends the iris season as well as providing variety of height, colour
and form for your garden.

Something special cooking in this 'kitchen garden'

2grow.jpgThere are 1,000 varieties of tulips at Keukenhof Gardens. Here, they sway behind a border of grape hyacinths.
If you’re a lover of spring flowers, especially tulips, a trip to the Keukenhof Gardens near Lisse, in the Netherlands may interest you.

Keukenhof, meaning “kitchen garden,” is situated on the grounds of a former castle, inhabited during the 15th century, where herbs and vegetables originally were grown to be used in the local palace kitchen.

In 1857, the gardens were landscaped by Jan Zocher, a prominent Dutch landscape architect, where some of the over 2,500 trees now visible in the park still remain.

1grow526.jpgView full sizeColorful Gerbera daisies brighten the landscape.

Established in 1949 as a flower exhibit, growers from all over the Netherlands and Europe displayed their latest hybrids in an attempt to boost the Netherlands’ export industry. All types of bulbous plants are showcased in this floral extravaganza, as are a variety of perennials. Growers donate their bulbs which are planted according to a “master plan” for the year.

The gardens have now grown to attract 850,000 visitors annually, who come from all over the world to view the over 70 acres of spectacular floral displays.

LARGEST
FLOWER GARDEN


With 7 million flower bulbs planted annually in the park this is the world’s largest flower garden. There are 1,000 varieties of tulips — national emblem of the Netherlands — alone. In the Keukenhof Gardens, visitors celebrate spring in all its magnificence with breathtaking, multi-colored gardens. The gardens include Europe’s largest fountain, a 700-tree labyrinth, a scavenger trail and petting zoo for children.
3grow528.jpgView full sizeDifferent varieties of Sedum draw the eye.

There are many inspirational gardens, incorporating garden sculptures, to gaze at along with ponds and waterways, pavilions showcasing flower shows, greenhouses, children’s play areas and a boat tour through tulip fields. The latter are so huge they can be seen from a plane, appearing as strips of huge bright ribbons covering the ground.

The Annual Flower Parade, with over 20 floats filled with millions of flowers, is a highlight each year along with various parades during the Easter weekend. There are seven special inspirational gardens at Keukenhof including the Garden Lovers Garden; Decking Garden; Town Garden; Outdoor Room; Woodland Garden; Round Garden and the Patio Garden.

PERMANENT FRAMEWORK

Each garden has a permanent basic framework of trees, shrubs, hedges and wooden walls or fences. But the rest of the plantings, including perennials and flower bulbs, are replanted and reorganized every year according to current garden trends. Each garden is different, ranging from romantic pastels to more colorful folk gardens.

Increasingly more attention is being paid to the environment, with the result that there is less paving and more greenery. Each spring containers and garden furniture are used to create a totally different feeling. There are plenty of places to sit, relax, meditate and drink in the unique flavors of the gardens.

Flowers, flowers and more flowers! Open for only six weeks each year, this year the garden was open from March 18 to May 16, 2010, showcasing the theme “From Russia with Love.” A Russian flower mosaic of St. Basils Cathedral using 70,000 bulbs was just one display interpreting the theme.

All this splendor is crammed into a few short weeks each spring. When the gardens open in March the display begins with daffodils, crocus and narcissi. Tulips appear a few weeks later along with hyacinths.
4grow528.jpgSeven million flower bulbs are planted annually in the park. This photo shows a group of fritillaria.

It’s said the best time to visit is the last half of April, but when I recently visited early this month the flowers were magnificent. Weather at this time of year can be quite windy and cool with temperatures in the 40s and 50s, so if you’re planning to take this trip, be sure to dress warmly.

From May 6 through 16 the largest Lily Show in the world was held in the Willem Alexander pavilion of the Keukenhof, featuring over 20,000 lilies, including 300 different varieties. Another pavilion displayed a huge variety of delicate orchid plants.

YEAR-ROUND INDUSTRY

In Holland, flowers are a year-round industry. Since the bulbs are not dug up until late summer, when their leaves have absorbed enough food to nourish next year’s bloom, they cannot be shipped until early fall. Growers are stationed at kiosks throughout the park wielding huge, colorful books containing pictures of bulbs that are available for you to order. If you visit the gardens, be sure to bring a pad and pencil to write down the names of the bulbs and their growers.

Next year, the Keukenhof Gardens theme will be “Germany: Poets and Philosophers” and the garden will be open from March 24 to May 20. Admission tickets can be purchased online in January, 2011.

To arrive at Keukenhof, visitors can travel the waterways of Holland and Belgium on a riverboat cruise that includes a tour of the garden, as I did, drive one hour from Amsterdam, or travel the Netherlands Railway, which sells a special Keukenhof ticket that will take you via bus from the Leiden Central Station.

Although Keukenhof is the most photographed place on earth, it’s impossible to capture the beauty of these gardens and their brilliant bulbs and flowers in pictures. This is a “garden-lovers garden” that must be visited in person to experience the true splendor of spring.
