De Ruiter Roses has two different cultivation methods: cold and warm cultivation. Cold cultivation is seasonally based and means that the greenhouse is not heated. Warm cultivation is used for year-round cultivation. De Ruiter Roses has both because, as a breeder, it wants to be able to display all its varieties in its show greenhouses. Moreover, De Ruiter keeps roses in production in small numbers, which are no longer in production elsewhere.
The growing process begins with the placing of the cutting of The Palazzo Rose in a pot filled with coconut coir for cold cultivation, or in stone wool for the heated greenhouse. The cuttings are given water and fertilisers using a kind of drip feed around 5 times a day in winter and around 20 times a day in summer. This process is managed by continuously measuring the concentration of nutrients and the water level.
So you see The Palazzo Rose is well taken care of.
From the moment that the cuttings are placed in the stone wool or coconut coir, it takes 8 to 10 weeks before the first flowers can be cut. In the meantime, the roses are “side pruned.” Side pruning means that the side branches are removed. The reason for doing this is that these branches take energy away from the main branch. Side pruning therefore allows the bloom to grow bigger. This is a natural reaction on the part of the rose which ultimately only has one bloom left to ensure its progeny, and therefore makes it extra large and beautiful to get it noticed by insects.
The Palazzo Roses are cut at the required ripeness and usually placed in water in the cool room for 24 hours. In this time, the rose soaks up water, nutrients and anti-bacterial agents. This is designed to give the rose sufficient reserves for transportation in boxes, which is the case with air transportation.
The final step is to select the flowers by machine according to length, bud size and ripeness. This enables the quality to be monitored–from the first stage to the last.
