Portuguese Laurel Problems
Portuguese laurel, or Prunus lusitanica, is a popular choice for hedging due to its glossy leaves and ability to thrive in various conditions. However, like all plants, it can sometimes face challenges. One issue that seems to be common is stunted growth or a difference in health between plants in the same hedge. Let’s explore the potential problems and solutions.
The Problem: Stunted Growth and Pale Leaves
Some Portuguese laurel owners have observed that while most of their hedge thrives, one or two plants may exhibit stunted growth, with leaves that are not as deeply green as the others. This lack of vibrancy and growth can be concerning, especially when there’s no obvious sign of disease like yellowing leaves.
Possible Reasons and Solutions
- Inadequate Watering:
- Symptoms: One of the main reasons for this could be insufficient water. Even established hedges can suffer from inconsistent watering, especially during dry periods.
- Solution: It’s recommended to water the laurel generously. Pour water slowly around the roots to ensure absorption and avoid runoff. Watering twice a week, especially during warmer months, can make a significant difference. It’s important to note that while a particular plant may show signs of drought stress, it’s beneficial to water the entire hedge consistently.
- Competition for Resources:
- Symptoms: A Portuguese laurel located near the boundary of a large neighbouring hedge might struggle because the vast network of roots from the neighboring plants could be consuming the water and nutrients meant for the laurel.
- Solution: Regular feeding can help. Consider using a seaweed feed or another suitable plant feed every month or so to ensure that your laurel gets the nutrients it needs. Additionally, ensuring a thick layer of mulch around the base of the laurel can help retain moisture.
- Variety Confusion:
- Symptoms: A noticeably smaller growth might raise questions about the variety of the laurel. For instance, the Otto Luyken is a dwarf variety of the cherry laurel, not Portuguese laurel. Its growth is naturally stunted compared to the regular varieties.
- Solution: Ensure that you’re planting the desired variety. However, if you’re certain about the type of laurel you’ve planted, then the size discrepancy isn’t due to variety differences.
Conclusion
While Portuguese laurels are generally robust, they aren’t immune to challenges. Regularly observing and comparing the health and growth patterns of each plant in your hedge can help identify problems early. Whether it’s adjusting your watering routine, adding nutrients, or reconsidering the positioning of the plants, a proactive approach can ensure a lush and healthy hedge year-round.
