High temperatures can quickly weaken orchards, berry plantations, vegetables and field crops. After a period of heat stress, plants often reduce nutrient uptake, lose turgor, slow down growth and respond less effectively to further treatments.
That is why crop recovery after heat stress should begin with support for the root system, improved nutrition and reduced effects of stress. The key is to act gradually, according to plant condition and the current situation in the field or orchard.
What Happens to Plants After Heat Stress?
During strong heat stress, the plant focuses on survival. It limits transpiration, closes stomata and slows down metabolic processes. In practice, this may lead to weaker water and nutrient uptake, reduced growth and higher sensitivity to further damage.
After such conditions, plants need support both through the root zone and through the leaves. Foliar application alone may not be enough if the root system is weakened and does not work properly.
Step One: Support Through Fertigation or Watering
The first step should focus on supporting regeneration and restoring plant activity.
We recommend using:
VitaExpert Regenerum + VitaFer Vigor
through fertigation or watering, at a concentration of:
0.25% of each product
This combination supports plants in rebuilding their condition after stress, helps provide nutrients needed for further growth and improves conditions for root system recovery.
Step Two: Foliar Application After Stress
The next part of the programme is foliar support. After heat stress, leaves are often weakened, and the plant needs ingredients that help it return to more efficient physiological activity.
Recommended foliar application:
VitaExpert Stress Control: 0.5–1 l/ha
VitaFer Algi: 1 l/ha
VitaExpert Stress Control provides potassium and proline, which support plants under stress conditions. VitaFer Algi, thanks to ingredients derived from algae, helps improve plant condition and supports natural recovery processes.
When Should the Treatment Be Repeated?
The foliar application of:
VitaExpert Stress Control + VitaFer Algi
should be repeated after around 7 days from the first treatment. This is especially important when plants remain weakened, weather conditions are still difficult or heat damage is clearly visible.
Repeating the treatment helps maintain physiological support during the period when the crop is returning to balance.
Crop Recovery Programme After Heat Stress
In practice, the strategy may look as follows:
1. Fertigation or watering
VitaExpert Regenerum + VitaFer Vigor
concentration: 0.25% of each product
2. Foliar application
VitaExpert Stress Control: 0.5–1 l/ha
VitaFer Algi: 1 l/ha
3. Repeat foliar treatment
after around 7 days
The programme should be adjusted to the crop species, growth stage, level of damage and technical possibilities on the farm.
Crop Recovery Requires a Fast but Balanced Response
After strong heat stress, timing matters. At the same time, treatments must be chosen carefully. Plants weakened by stress do not always respond well to intensive actions, so recovery should be carried out step by step: first support through the root zone, then foliar application and observation of plant response.
VitaExpert Regenerum, VitaFer Vigor, VitaExpert Stress Control and VitaFer Algi can be part of a strategy supporting plants after heat stress. This approach is especially useful in orchards, berry crops, vegetables and field crops where high temperatures have strongly affected plant condition.
