Protecting your cherry trees from frost: A friendly guide

One of the greatest challenges facing farmers in central and southern Chile is undoubtedly frost, especially its impact on cherry trees, "the new copper" of Chile.the new copper" of Chile".

When a frost event occurs, delicate cherry blossoms and buds suffer irreversible damage, massively affecting seasonal fruit production. 

Not all frosts are the same. Depending on the temperatures reached, the amount of damage caused to the cherry trees may vary, but it is this very reason that makes it important to develop a plan of action in case of one of these events.

For agronomists and cherry growers, it is necessary to prevent and mitigate frost damage to protect their crops, so here are some relevant tips.

Anti-frost strategy in cherry trees

Monitor the weather

You should pay close attention to the weather forecast during fall 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.

Choose the location carefully

If you plan to plant a cherry orchard, consider location. Sites that are at higher elevations or that are protected from winds may be less prone to frost. Choosing a location wisely can reduce the need for resource-intensive interventions.

Try blankets or comforters

Blankets can be useful to protect cherry trees from frost. These can be covered when frost is predicted and removed once the temperature rises. This is a low-impact solution that can be effective, but it is costly and generates an enormous amount of waste.

Sprinkler irrigation

Spray irrigation can be an effective technique for preventing frost damage. The water will release heat as it freezes, which can help keep the temperature of buds and flowers above freezing. Although this technique must be used with care to avoid excessive water use, in the heart of central Chile, we have developed a frost control technology focused on sustainability and water efficiency. So that is where the low precipitation concept that we promote here at Tierraverde comes from.

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. While 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. Finally, we should not forget the decibel factor, which in several communities has become a conflict situation, as they sound almost like a helicopter.

Prefer frost-resistant varieties

Some cherry varieties are more frost resistant than others. When selecting trees for your orchard, you may consider choosing varieties that are known for their frost resistance. Not only can this help protect your crop, but it can also reduce the need for resource-intensive interventions.

Uses soil management techniques

Soil management techniques, such as mulching or planting ground covers, 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 of these recommendations, you are sure to "take control of your climate. With the right preparation and strategies, you can minimize frost damage and maintain the health and productivity of your cherry trees.
