August sees the results of the years work and is basically the countdown to the flower show.  The first week saw the start of the final shaping of plants with stems adjusted to what will hopefully be their final flowering positions.  This is an ongoing process and plants will still need to be adjusted. The aim is to allow each bloom enough space to develop and be shown off to their full potential.

The feeding programme is altered three weeks before the show the balanced feed is changed to a high potash.  Again, fed full strength every watering with an occasional plain water to prevent the build-up of too much salt in the pot.  The flower stems are now in position and the blooms can be fed.  It is a continual task to remove leaves and pull blooms into position, but if this is done now it is easier later.

The final two weeks see the final positioning of the blooms using the nbs bloom supports, this was quite a task as in total I used almost 800, but the result is well worth it.  This is a slow process as blooms are easily damaged, and worst-case scenario knocked off.  The supports can be used to adjust the position of each individual bloom, but care must be exercised in not over tightening at this stage as the stem can be damaged resulting in the bloom rotting off later.

Getting pots to a show is another task and my solution is to wrap the blooms in cotton wool again a lengthy task but there is no point in growing for a year to damage them on the way to the show. The bloom supports are gently tightened to ensure each flower is fully supported and facing the correct way.  I prefer to do the final preparation in the greenhouse rather than at the show.  The cotton wool prevents the bounce that can damage the blooms in transit.  If two plants are close together in the van a drape of cotton wool over a plant can prevent damage from foliage rubbing the blooms. 

I water the plants before packing them in the van if required as the additional weight along with the wide bottom pots I use provides additional stability.  A good tip is to keep a supply of new pots the same size as they can be used to drop the plant into if the pot is becoming grubby, a small point but presentation is awarded points and worth doing well.

The final part of exhibition is to display them on the bench, I prefer forward facing pots for two reasons.  Firstly, I can display them for maximum effect in my own greenhouse, it is payback for all the hard work just to be able to sit and look at them late on at night, when for some reason begonias always seem to shine.  Secondly pots are almost always displayed against a tent wall and it seems a waste to only see half the flowers.
