| APRICOT COURTIER AND FORMCAST by Jack
Kevan, Collin |
I grow Apricot Courtier and Formcast because they
flower early in the season and are very consistent. Both cultivars develop very heavy
plants without much feeding. I have grown these cultivars for some time now - Apricot for
ten years and Formcast for si x years.
Taking cuttings
The first cuttings are taken during the second week of December and then every
seven days until the first week in January. Both cultivars produce an abundance of
cuttings. My rooting medium is equal parts JI no 1 plus peat plus 3mm grit, I don't use
hormone rooting powder. Cuttings are rooted on the open bench on a soil warming cable.
Potting on
Moving on is into 4" deep plastic trays using a JI no 1.5, cuttings are watered
before moving, then water is withheld. Initially only about 2" of soil is put into
the trays with more soil added as the plants grow. They will stay in these trays until
planting out. There are only 8 plants per tray.
Stopping in batches
Stopping the plants takes place 10-12 weeks after rooting, starting at the end of the
first week in March and then every 7 days. Just a small tip is taken out. I do no use
growth retardant on these cultivars.
Preparing the plot
Ground preparation starts in October for the following season. I dig it over adding 8oz of
6X Concentrated manure to the square yard. Basamid is also incorpoated as I dig. I then
roll the soil, flood it with water and cover it with polythene. The polythene is left on
until February.
I usually have a soil test done professionally every two
years, relying on DIY tests in between. For my base dressing I put on 2oz Vitax Q4 and 1oz
Nitroform.
Covers up pre-planting
Covers are put on place 10 days before planting out, usually at the end of April. They are
removed in the first week of June. Planting takes place about 10th May or thereabouts
depending on the we ather. I grow about 300 plants, mostly reflexes. Planting is done
using a domino five system with spacing about 22" x 18". I wait for about 10
days after planting before reducing the number of laterals. Most plants are planted out
with three laterals, thi s is then reduced to two.
No feeding!
These varieties do not take to bloom feeding, they do not like feed at all! As I live in a
wet area I tend to stay away from additional feeding.
Protecting plants and blooms
Spraying starts early in the season, ringing the changes: Sybols/Nimrod T,
Tumbeblite/Tumblebug, Derris, Malathion, Murphy's Systemic every seven days. Since the
black fly started I give a drench in between the seven days with a very weak mixture of
Armillatox - this is sprayed on the bottom half of the plant.
Special attention is taken at bud time, making sure the
buds are clean. These cultivars have a tendency to cock buds; I've tried taking the bud
early and late but it still happens. The bud is cleared of all side growth by the time it
is the size of a pea.
Covers go on during the first week in August. Normally
there are quite a few flowers in colour by this time and these are double bagged with bud
bags for about 10 days. I drench the buds with Pirimor and snip off the small bracts below
the bud. Buds are s prayed up to the paint brush stage. I also smear Vaseline on the stem
about 1.5" below the bud.
Preparing for exhibition
When cutting blooms for local shows I do not boil the stems, however if I am travelling
any distance to a show then the stems are boiled. Blooms are normally cut 24 hours before
the show. I expect to get an 80% cut from Apricot Courtier but only 50% from Formcast as
this cultivar has the habit of lifting around the crown. Not much dressing is needed, just
a g ood tidy up. Both cultivars are very heavy in the stem so there is no need for
additional staging supports. They are easily matched for size, colour and stage of
development.
End of season
I start to clean up the stools as soon as possible after the sho ws are finished. They are
washed and trimmed ready for hot water treatment and all green growth is removed. The hot
water treatment is carried out about 9 weeks before cuttings are required. After treatment
stools are left to drip dry for two days, they a re then boxed up and sprayed and placed
into the cold frame. Stools are taken into the greenhouse at the beginning of November
when most of the stools are showing signs of life. These are two healthy cultivars, in my
experience free from problems such as crown gall.
