e Planting material

We strongly advise tubers of size

I, with a weight of 100 grams or

more. It will produce more shoots

because it has more growth eyes.

Storage

Storage in crates at a temperature

of 7 to 9 degree C until planting.

The relative humidity should be

neither too low (due to the risk of

fungal diseases) nor too high (due

to the risk of disiccated tubers).

Avoid air circulation.

Soil

Dahlias will grow in any type of

soil. The ideal pH value is 6 to 7.

Applying lime will increas the pH.

Good drainage is necessary to

keep the underground parts of the

plant from rotting; this means that

water should drain quickly follow-

ing heavy rainfall. Dahlias have

large leaf surfaces and transpire

large quantities of water. This wa-

ter can be absorbed by the roots

only when soil moisture levels are

favourable. For these reasons,

frequent monitoring of the soil

moisture is important.

Provide water frequently but in

small quantities; one way to do this

is by using drip irrigation hoses in

the planting bed. Insufficient mois-

ture results in slow growth, fewer

flowers and leaf yellowing.

Nutrients

The soil must contain adequate

levels of potassium and phosphate.

If the level of phosphate is too low,

this nutrient will have to be applied

to the soil before planting.

Potassium can also be applied be-

fore planting. Work the potassium

and phosphate thoroughly into the

upper 15 cm of soil.

The application of nitrate can influ-

ence the vegetative development

during the growth period. Moni-

tor the colour of the leaves (they

should remain bright green) and

strive for a continuous develop-

ment of leaves and flowers.

A nitrate defiency will result in short

plants with a pale leaf colour, but

too much nitrate willproduce strag-

gling, limp plants.

Planting period

Dahlias grow the best at tempera-

ture between 15 and 25 degree C.

They will not tolerate any frost.

Practical tipsCut flower production of Dahlias

Types of Dahlias

Choice of cultivars

Choosing suitable cultivars is the basis for success. Their bright colours are

what make dahlias favoured as cut flowers, but their fairly short vase life was

- for a long time - a negative factor, limiting an optimum growth in sales.

Breeding efforts, however, have recently led to the availability of several

cultivars with a good longer lasting blooming time. Important characteristics

toconsider when selecting dahlias to produce as cut flowers are how most

flowers they produce, flower shape, flower colour, length and sturdiness of

stem, and a minimum amount of laetral branching. Many cultivars should

not be harvested when too immature because their flowers will fail to open

in the vase. Today we produce dahlias with a vase life of 7 to 10 days.

Ball Small & MediumDecorative

CactusLarge & GiantDecorative

Pompon

34 35

A ground frost that follows the

planting is not a problem. Under

Dutch conditions, planting for

outdoor production is in May.

Planting density and planting

6 to 8 tubers per square meter.

Fewer if using cultivars with a

large, more spreading habit. Cover

the crown of the tuber on which

the growth eyes are located with 2

to 3 cm of soil.

Bloom period

In the field , under Dutch condi-

tions between July and end of

September. After September the

quality of the plants suffer from

insufficient light and fungal infesta-

tion resulting from a high RH.

Weed control

Weed can be controlled by the use

of herbicides. Start with a weed

free planting bed. After planting

the tubers but before the emer-

gence of the shoots, the germina-

tion or early development of

weed seeds can be prevented by

spraying a soil-applied herbicide

(Stomp, 3 liter per Ha.) according

to instructions.

Spray during the evening but not if

hot sunny weather is predicted for

the next day. Hoeing and weeding

by hand is a safe but labour-inten-

sive alternative.

Support

Tall dahlias need support, the

weight of the plant and its flowers

is so great that high wind can bring

damage. Use chrysanthemum

mesh or guywires placed around

the edges of the bed.

Disbudding

To produce long attractive stems

and larger flowers, remove axillary

shoots. A dahlia plant continues

to produce new offshoots. Har-

vesting the flowers stimulates this

and makes it possible to continue

harvesting over a long period.

Harvesting flowers

For uniform flower maturity, it is

important to cut the flowers every

day. On warm days harvest early

in the morning or late in the after-

noon. Flower stems should be

trimed to the desired length.

Bunching can be done imme-

deately in the field or later in the

processing facility. Remove the

lowes leaves. Trim the flower stems

in each bunch to the desired

length and place them in a water-

filled container. Use a chlorine

tablet to prevent bacterial growth.

Storing flowers

Place the flowers in a cold storage

room at 2 degree C. Nutrients for

cut flowers (Chrysal) stimulate the

flowers to open, extend vase life

and keep the water in the vase

clean.

Winter activities

The ground frost in the autumn

means the end of flower harvest-

ing. Remove foliage from the soil

to get rid of pathogens. Lift the

tubers and dispose of them. If the

soil does not allow lifting, apro-

longed frost will be enough te

freeze the tubers.

Pests and diseases

Various pests and diseases can affect the production of dahlias for cut flowers. Here are the most common ones accompanied by their control measures.

Remember to consider hygiene and to start with healthy starting material.

Cause

Dahlia smut

(Entyloma dahliae)

Aerial stalk rot

(Sclerotinia sclerotiorum)

Aphids

Spider mite

Thrips

(Thrips tabaci)

Symptons

Light green to yellow round spots and sometimes angular spots bound-

ed by veins appear primarily on the lowest leaves and measure from 2

to 10 mm across. The infection occurs mainly during flowering and then

particularly under humid conditions.

The sudden weakening of one or more stalks on a plant is a symptom of

this disease. Large sclerotia with the appearance of rat faeces form inside

the hollow stems. Damage occurs primarily on plots that are regularly

used for producing host plants such as Dahlia, beans, Chrysanthemum,

Liatris and potatoes.

The upper leaves of young shoots become misshapen or tightly curled.

Clusters off black or green aphids can be found on the undersides of

these leaves and sometimes on young stems and flower stems as well.

Affected leaves turn dark brown in places and fall off prematurely. These

symptoms are generally caused by Tetranychus urticae (Red Spider Mite)

that occurs on many host plants. Hot dry weather increases the

reproduction rate of spider mites.

Affected plants display a noticeably slowed rate of growth. Often, the

lowest leaves are shaped normally but the younger leaves are highly

misshapen. Flower formation is also disrupted. Hot dry weather increases

the reproduction rate of thrips.

Prevention/control

Use a generous crop rotation period. Choose a

planting density that will allow the foliage to dry

quickly after rainfall. Remove and destroy disease-

dand dead plant parts. If necessary, spray with a

fungicide according to instructions.

In case of an infestation, spray with a fungicide

according to instructions. Remove and destroy

diseased plants along with neighbouring plants.

Steam infected soil. Use a generous crop rotation

period.

If necessary, spray with a insecticide according to

instructions.

Spray regularly and according to the instructions

with an agent that controls red spider mite.

Spray with insecticide according to instructions.

Be sure to treat the tips of the buds thoroughly.
