Increasing environmental awareness and the need to eliminate the use of chemicals has led to a new philosophy in rose breeding. Many older rose varieties do not meet today’s requirements for disease resistance and abundance of flowers without the use of chemicals. Kordes’ have stopped the use of fungicides on their trial grounds allowing them to accurately assess each varieties characteristic. This has resulted in only the healthiest roses amongst the thousands on trial being released onto the market.
The new philosophy of roses breeding has meant that in comparison older varieties are more susceptible to disease. As a result, older varieties are gradually being removed from the market to be replaced with more resistant new releases.
If you are in search of roses that are beautiful, disease tolerant and easy to care for, look no further then Kordes' bred roses.
