Dahlia:
Great late summer
flowers that thankfully are now welcomed in the most fashionable of
gardens as well those of us who love beautiful flowers and couldn't give a
hoot about fashion. There is an incredible range of Dahlias available and
new ones are being introduced all the time - like all "hobby
plants" most are breed by extraordinarily dedicated and skilled
amateurs. Its not in the remit of this catalogue to review this wide and
wonderful range of plants. We grow a few varieties in the our garden and
we hope to be able to add some to our list during the coming years.
Dahlias love rich
soil. When planting dig out a big hole and add compost and bone meal to
the hole and soil you return to the hole. Large flowered varieties will
need staking. Watch out for slugs and snails on very young plants. I
always grow them on to about 1ft tall before planting. If you want really
big flowers you will need to pinch off the side buds and leave only the
main bud to develop - I don't bother, the flowers are big enough anyway.
Deadhead especially in autumn as dead, wet blooms can get grey mould. Distorted,
one-sided blooms are a sign of caspid bug - spray on the odd occasions it
is a real and persistent problem. Tattered blooms mean earwigs are eating
the flowers at night - put an upside down pot filled with straw or shredded
paper on top of a cane amongst the blooms - empty our each morning and
destroy any earwigs.
Cut the stems down to
about 3in above the soil when frost has blackened the stems in late
autumn.
Dahlias can usually be
left in the soil through winter if 1) the soil is not overly wet and 2)
you don't live in one of the colder regions of the UK. One benefit of
digging up the tubers is that you can more easily take cuttings in spring
from the part-covered tubers in a shed or greenhouse. If digging them up
store in a frost-free shed in slightly moist peat or equivalent. Stand
them upside down for a week or so to drain any wetness out of the stems. I
then stand mine in trays 3/4 cover them.
if you really get the
Dahlia bug there are local Dahlia societies you can join.
