Soil & Climate
Soil
:
The ideal soil for chrysanthemum growing is a
well-drained sandy loam of good texture and aeration.
The soil should be neutral or slightly acidic
with pH 6.5 to 7.0 having high organic content.
Very light sandy soils are not recommended owing
to their poor moisture holding properties.
Climate :
Light :
Light is one of the most important climatic factors
influencing the growth and flowering. The flowers
of chrysanthemum are very much influenced by the
quantum and quality of light; most of the cultivars
require shorter days for flower bud initiation
and development. Under long day condition, chrysanthemum
tends to remain vegetative. As it is a short day
plant, it naturally flowers in autumn and winter.
Temperature :
Based on the temperature
requirements chrysanthemum cultivars are classified
into 3 groups
- Thermozero cultivars: Varieties,
which flower at any temperature between 10-27°C,
but most constantly 16°C night temperature.
- Thermopositive cultivars:
A minimum of 16°C required for initiation
and at 27° C there will be rapid initiation
but delayed flowering.
- Thermonegative cultivars:
Bud initiation occur at low or high temperature
between 10°C and 27°C but continuous
high temperature delay bud development.
Altitude
:
It can be successfully grown upto an altitude
of 1200 m elevation.
Relative Humidity :
A relative humidity of 70-90% is optimum for growing
chrysanthemum.
