Underwatering trees can cause several noticeable symptoms, indicating that the tree is not receiving enough moisture to meet its needs. Here are the key signs to watch out for:
- Wilted or Drooping Leaves: This is often the first sign of insufficient water. The leaves may look limp and lifeless as they lose their firmness due to the lack of water pressure inside.
- Dry, Brittle Leaves: Leaves that are underwatered will often feel dry to the touch and may crumble easily. They might also appear crispy and can break when bent.
- Leaf Scorch or Browning Edges: The edges or tips of the leaves may turn brown and dry out. This browning can sometimes be confused with burning from too much sun or chemical exposure, but it can also be a drought stress symptom.
- Early Leaf Drop: A tree conserving its remaining moisture might begin to shed leaves prematurely. This is more common in deciduous trees as they try to reduce water loss.
- Yellowing Leaves: Before falling off, some leaves might turn yellow. While yellowing can be a symptom of various issues, including overwatering, nutrient deficiencies, or diseases, it’s also common in trees suffering from drought.
- Slow Growth or Stunted Growth: Trees that do not receive enough water often have stunted growth. New leaves may be smaller than usual, and the tree may not put on as much new growth as expected during the growing season.
- Visible Cracks in the Soil: If the soil around the tree is cracking and pulling away from the trunk, it’s a clear sign that the soil is too dry.
- Compacted and Dry Soil: When soil is dry for prolonged periods, it can become hard and compacted, making it difficult for water to penetrate and reach the tree roots when watering does occur.
To address underwatering, ensure that trees receive deep, infrequent waterings that moisten the soil to the depth of the root system. This method encourages roots to grow deeper, making trees more drought-resistant. Mulching around the base of the tree can also help retain soil moisture and protect roots. In regions like Calgary, where water management is crucial due to variable climate conditions, monitoring and adjusting your watering practices based on weather patterns and seasonal changes is essential.
