Rose

Rose is a crop that is grown on the same substrate for several years. This requires additional firmness and stability of the substrate, so the crop can continue to make optimal use of the total substrate volume throughout the entire cultivation period.

Because rose crops should continue to produce optimally year round, good and instantly steerable slabs are of great importance. In addition, a new trend among increasing numbers of rose growers is to recirculate drainage water, and to increase the use of biological crop control methods.

Preparing for a new crop

It is important to give the best possible start to the new crop. The turn-round period offers opportunities to clean the glasshouse and carry out essential maintenance prior to its arrival. Commercial pressures sometimes mean that the glasshouse is only empty for 2-3 weeks. However a good clean up in this period will pay dividends for the cultivation to follow.
