Chrysanthemums are the ideal
plant to grow when wanting to extend summer colours in the
border. At the same time the later flowering cultivars aptly
provide beautiful shades of late autumn. The early flowering
chrysanthemums and sprays make superb long lasting cut flowers.
Plants are grown in 10cm. plastic pots and
are available from the last week in April. For best results
they should be planted out in the open ground early in May,
or as soon as weather conditions permit, allowing 30cm square
for each plant. Plant with humus and a good general fertiliser
which is high in nitrogen.
CONTROL OF PESTS AND DISEASES
This should be a routine rather than a control
of the problem. Every 2 weeks from early May until they come
into flower, the plants should be treated with ‘Sprayday’.
This will control powdery mildew, rust, red spider, aphid
and white fly. ‘Provado’ will control Leaf Minor,
Capsid and some of the above. Always follow instructions
on product label.
EARLY FLOWERING CULTIVARS.
On
average chrysanthemums grow to approximately 1-1.2m and should
be staked at planting, there are various ways of doing this,
depending on individual needs.
Two weeks after planting the plants that have
not already been stopped by us, should be stopped by pinching
out the main stem and grown on to develop 6 or 7 shoots.
Disbud for large blooms
SPRAY CHRYSANTHEMUM
Ideal for garden decoration or cut flowers.
Growing to approximately 90cm. Flowering August - September.
At planting if the plants have not been stopped by us they
should be stopped at planting leaving 4 shoots and three
weeks later stop again, leaving a total of 8-10 shoots for
flowering. No disbudding will be needed.
GARDEN MUMS – SHOWMAKERS and YODERS
These
are the shorter compact cultivars that make superb pot plants
ideal for the patio. They can also be planted in the front
of borders to give a superb splash of intense colour.
The Showmaker varieties tend to be earlier
flowering followed by the Yoder varieties for excellent Autumn
colour.
These cultivars are stopped by us and then
are self branching.
