Episode 11 –
mid July
I am always
conscious of how fortunate we can sometimes be here in our little corner
of the British Isles compared to the rest of the country regarding
summer temperatures, especially in my own garden. For the majority of
June, while most of the country baked in temperatures in the high
twenties and above, we were sometimes 5 degrees below. Now please don’t
be misled when you see the forecast map with 18°C hovering above
Newcastle day after day; they are the coastal temperatures whereas 10
miles inland the influence of the North Sea lessens but we have
certainly been ‘less hot’ that the rest of the country. These are once
in a decade temperatures that many of us are experiencing, although I
know that Phil Champion would have taken issue with that statement a
couple of years ago!
With regard to
my own patch, I may have said it before but I am lucky with the location
of my greenhouses. I don’t take any credit for this – the house wasn’t
bought with begonias in mind and there was nowhere else in the garden to
put them so it really was ‘Hobson’s Choice’ regarding their site, but
being surrounded by walls on three sides usually ensures that I don’t
have sunlight heating them up from the sides and the low level air
outside of them is kept quite cool because of the walls so this cooler
air is constantly being drawn into the greenhouses.
Shrewsbury
plants
So far, my biggest issue is timing. At bud securing time, I found myself
on too many occasions with one bud too advanced and the next one too
small. The only logical thing to do, especially with the warm weather we
are experiencing was to take the smaller bud as the bigger ones will in
all likelihood be too early, so only time will tell. I kept feeding
Vitax balanced until two weeks after securing because of the temperature
and the look of the leaves and then went onto a higher potash version,
as I don’t want to risk soft petals. Here is how they looked on July 16th
see below left and again on the 22nd below right. Looking at
them now I am wishing that I had taken more smaller buds because far too
many of them are almost a week further on than I would like and with no
prospect of cooler weather I think quite a few will have gone over by
Shrewsbury time.
Despite my best
efforts in positioning the sticks, some varieties are still being
awkward and the buds are facing the wrong way, none more so than
Sweet Dreams – as usual. This is frustrating for three reasons
●
The
stick of the plant in front can become perilously close to the bloom –
see below left
●
The
plants look bare when they are turned through 180 degrees – only
cosmetic so not that much of a concern
●
The
leaves do not get enough light as they are tucked beneath the foliage of
the plants on the staging behind – more concerning– see below centre. I
often put suspect varieties on the back staging when setting the plants
out but overlooked them this year; I must have a swot up of my Feng Shui
for Begonia Growers manual!
Dundee plants
These all had a half strength balanced feed every week for the three
weeks before securing; two in the case of the 7 week varieties – the
majority are only in 3 litre pots and many had been in them for 6 weeks
when I started feeding.They
are now growing well with virtually all of the buds secured and
generally speaking there were more of them of the right size on the day
compared to the Shrewsbury plants. Also, there were hardly any ‘iffy’
looking buds as well – so far! Mind you,
one of the things that Colin and
I always
said in our chrysanthemum growing days was that at this stage, they all
look like winners! Here they are on July 16th –
see below left. The first Dundee buds to be secured included Tequila
Sunrise, middle tier and Tom
Brownlee, bottom tier – see below centre. The cuttings I
will be flowering have made good progress – see below right, and will
soon have to be placed into 5 litre pots weighted with sand to improve
stability.
Natural
predators
I am all for the use of natural predators, providing that they are
effective. The two most commonly used by begonia growers are ‘Amblyseius
Cucumeris’ for mite and ‘Steinernema
Kraussei’ for
vine weevil,
but over the last couple of years I have found the odd earwig hiding in
my buds, so because there are no real effective chemical controls
available for them these days, I am now using a biological alternative.
My control of
choice is ‘Hortulani
Caliga’ – for instruction on how to use it, see left to right below

Some little
(and not so little) things sent to try me
Early one late June morning, I must have had a puzzled look on my face
similar to the person who first discovered crop circles. The strange
marks on the greenhouse roof had me staring at them for ages – see below
left. On closer inspection on the outside they looked even stranger
until I eventually discovered the culprit – it was ants. They had left a
trail in the glass shading – I use Nixol, which goes almost clear when
wet, so the early morning moisture courtesy of the North Sea and the
River Tyne must have softened it enough for the ants to leave a visible
trail in it – the pattern shows the intricate paths they take and it
looks like the next ones follows it exactly – see below left and centre.
And I bet you thought the one about the leaf miner was boring!!!
A couple of
mornings later while I was making my second (or it might have been my
third) cup of tea Pauline shouted for me to quickly look in the garden.
I was just in time to see a couple of tree rats – wrongly called grey
squirrels by some folk – scarper out of one of the greenhouses and into
the trees. After a good look round the two big greenhouses I couldn’t
find any damage but when I went into my Alton I found their handiwork –
see below right
Managing buds
for flowering
When the buds
to be flowered reach the time for securing, I find the more time I can
spend with the plants the better. Little things like old bud stalks that
nestle in leaf axils – see below, and then rot need to be removed and
checking for these thoroughly is not a five-minute job.
I like to help
guide the buds into position and for this I use polypropylene fleece
either side of the bud. This will not turn the bud around but it does
help them come out of the foliage without getting twisted and it also
help keep the guard petal from becoming deformed. It is not used to
protect the buds from damage, just to keep them straight – see below
I do not put
the collars on until around 3 weeks before the show. I wait until the
neck has elongated sufficiently to allow plenty of space between the top
leaves and the bloom so I can put the collar on without risk of damaging
petals. The only time I put them on earlier is if the guard petals have
started to curl backwards towards the stem.
One other
essential job that is done was to attach the packets of Amblyseius
Cucumeris to combat any potential mite invasion – see below
Cuttings
My cuttings, in their various locations are progressing well and have
now been fed a couple of times with a balanced feed. They need regular
attention to pinch out growth from wherever it appears to encourage the
formation of a decent sized cutting tuber for next year –
see Lucy Allely before
and after pinching out - below

Entry forms
I always have to remind myself to check the show schedules well in
advance for the closing date for entries; if you are thinking about one
of the big shows this will be strict and rightly so. Bench space has to
be allocated well in advance, boards have to be made available and
transport arranged for equipment, paperwork prepared and all of this not
by full time paid officials but by volunteers who spend hours and hours
of their own time to provide us with such superb facilities for our
exhibitions. The 20th of July was the closing date for our
2018 National Show at Shrewsbury this year – here’s hoping for full
benches!
What’s keeping me awake at night?
Here’s a big admission – I suffer really badly from pre-show nerves – I
always have done, but only for the first show of the year mind you, then
I’m ok – once I’m in the car and on my way that is, but really it’s no
joke and for the last three years I have sort of found a cure by keeping
myself occupied during the morning by making something begonia related
before I start to cut and pack!
In
2015 it was another box to hold 6 cut blooms, 2016 I made yet another
one and last year I made one to hold 3 blooms, together with a platform
to level off the 2 boxes behind the front seats due to the slope on the
floor rather than just using bricks as I had in the past. This year, as
I don’t need any more boxes, I am planning on making something to lock
all of the boxes together to stop them from moving about. I’ve got a few
ideas in my head but need to finalise the design soon! I’m feeling a bit
daft now that I’ve just read this back to myself but there you go – my
secret is out! Any suggestions for a bit of begonia related handiwork
before the National Show next year will be gratefully received!
