Have you ever wondered why cut flowers wilt so quickly? Drafts can be a major cause. Drafts cause rapid evaporation of moisture in the flower, causing the flower to dry out faster. This can lead to premature wilting of the flower and a shorter lifespan.

Cut flowers are sensitive to temperature changes and should therefore be protected from cold drafts. Do not place the flowers in a location with a constant airflow, such as near an open window, air conditioning, or fan. This can also affect the color intensity of the flower.

Direct sunlight and high temperatures should be avoided as much as possible. This may sound contradictory, because light and heat are essential for the growth of plants, so-called photosynthesis. For an optimal growth there should be a good balance in climate between temperature, light and humidity. A plant in direct sunlight and high temperatures also need a high humidity, which is often lacking in room conditions.

There are 3 main reasons for cutting the stem:

To protect themselves from drying out, plants and trees drop their buds, blooms and leaves. For cut flowers and potted plants this dropping is often the result of over-production of the growth hormone ethylene; the only known gaseous, naturally occurring plant growth hormone. Ethylene gas regulates the ripening/ageing of cut flowers, potted plants, fruits and vegetable fruits. Ethylene gas is therefore purposely used to promote the ripening of fruit and the blooming of potted plants.

Leaves contaminate the vase water, just like stems do. The stem has to be in the water. The leaf however serves no purpose in the water. In fact, it has a negative effect! Therefore, it is recommended to remove the lower leaves which would otherwise be in the vase water. The additional positive effect of this is that it decreases the amount of evaporation because the total leaf surface is decreased.

Yield Predict is an AI-powered forecasting solution offered in partnership with Lima Labs. Using drone imagery and advanced analytics, it predicts harvest volumes up to two weeks in advance with high accuracy. Growers gain reliable production insights to plan labour, logistics and sales with greater confidence.

How do you improve the quality of your product? By constantly looking for ways to improve. This is why Beekenkamp Plants from Maasdijk collaborated with Chrysal to investigate how to improve the quality of their cuttings. “Our joint efforts make it possible to achieve more.”
