One of the major challenges facing farmers in the central and southern regions of Chile is undoubtedly frost, particularly due to its impact on cherry trees, "Chile's new copper".
When a frost event occurs, the delicate flowers and buds of cherry trees suffer irreversible damage, which massively affects seasonal fruit production.
Not all frosts are the same. Depending on the temperatures reached, the amount of damage caused to cherry trees can vary, which is why it is important to develop an action plan in case one of these events occurs.
For agronomists and cherry producers, it is necessary to prevent and mitigate frost damage to protect their crops, so here we are with some relevant tips.
Frost Strategy for Cherry Trees
Monitor the Weather
You must pay extreme attention to the weather forecast during autumn and winter, and even spring. If a frost is predicted, you should be prepared to take measures to protect your cherry trees. Anticipation is vital to maximize the effectiveness of your actions and investments in protection.
Carefully Choose the Location
If you are planning to plant a cherry orchard, consider the location. Areas that are at higher elevations or are sheltered from the winds may be less prone to frost. Intelligent location choice can reduce the need for resource-intensive interventions.
Try Covers or Blankets
Covers or blankets can be useful for protecting cherry trees from frost. These can cover the trees when frost is predicted and be removed once the temperature rises. This is a low-impact solution that can be effective, but costly and generates a considerable amount of waste.
Sprinkler Irrigation
Sprinkler irrigation can be an effective technique to prevent frost damage. Water releases heat as it freezes, which can help keep the temperature of the buds and flowers above the freezing point. Although this technique should be used carefully to avoid excessive water usage, in the heart of central Chile, we have developed a frost control technology focused on sustainability and water efficiency. Thus arises the concept of low precipitation that we promote here at Tierraverde.
Use Heaters or Fans
Heaters or fans can be used to increase the air temperature around cherry trees and reduce the risk of frost damage. Although these can be effective, they can also be extremely costly in terms of energy, so it is important to consider their use in the context of a sustainable management approach. Lastly, we must not forget the decibel factor, which in various communities has become a conflict situation, as they sound practically like a helicopter.
Choose Frost-Resistant Varieties
Some cherry varieties are more frost-resistant than others. When selecting trees for your orchard, you might consider choosing varieties known for their frost resistance. This can not only help protect your harvest but also reduce the need for resource-intensive interventions.
Use Soil Management Techniques
Soil management techniques, such as the use of mulch or planting cover crops, can help retain heat in the soil and reduce the risk of frost. These techniques can also contribute to the overall health of the soil and the sustainability of your orchard.
With all these recommendations, you will surely be able to "take control over your climate." With proper preparation and strategies, you can minimize frost damage and maintain the health and productivity of your cherry trees.
