Auricula are
very hardy having come from the mountains!
They love fresh air - even in winter and will
tolerate being snowed upon quite readily. The
main thing they hate is having "wet
feet". Always use a very well drained
soil so the plant 'carrot' doesn't rot. The
'farina' or 'meal' on some varieties is
spoilt if plants get wet from above. For show
varieties, always bottom water and keep in a
cool greenhouse or cold-frame to maintain
'show' conditions.
Brenda Hyatt
in her book "Auriculas Their Care and
Cultivation" says auriculas "...respond
to commonsense treatment and plenty of good,
clean, fresh air."
In their
natural habitat theya re protected in winter
by a thick snow blanket so frost will not
kill them. In hot summers they are prone to
distress so shade them in hot sunny weather.
Re-pot
plants in mid-summer when flowering is over
unless you are setting seed for planting next
year. A typical auricula compost would be:
Sterilized
soil (loam)
|
2 gallons
|
Moss Peat
|
1 gallon
|
Perlite or
grit (3-6mm)
|
0.5 gallon
|
Silver Sand
|
0.25 gallon
|
Slow release
fertilizer
|
1
dessertspoon
|
Charcoal
|
1
dessertspoon
|
Lime
|
1
dessertspoon
|
Gamma Dust
(vine weevil pesticide)
|
1
dessertspoon
|
Use 3"
to 4" full sized pots for your plants.
Personally, I prefer clay pots as they dry
out more quickly and plants are less prone to
rot.
Pests: Root
aphis is often a problem in the summer. At
repotting time either use a systemic
insecticide or "paint" the roots
with a mixture of 10% alcohol in water for a
more 'organic' solution.
