4. Cedrus brevifolia (Cyprus Cedar): less used ornamentally, but equally valuable for its resistance and adaptation to arid climates. Discover the Calocedro.

Dwarfing varieties such as Cedrus libani 'Nana' or Cedrus libani 'Sargentii' allow you to enjoy the beauty of the cedar in smaller gardens, as they are more compact growing specimens.

Ornamental, historical and practical uses of cedar

Essential care of ornamental cedar

El ornamental cedar It is a rustic tree with few requirements, but to ensure good development and maintain all its beauty it is key to follow certain guidelines. cultivation and maintenance:

Location and exposure

• Light: Prefer full sun, although species such as the cedrus deodara They can adapt to semi-shade.
• Shadow: Some tolerance in specific species, but development may be slowed and final growth may be less vigorous.

When choosing the final location, consider the large potential size of these trees (up to 45 meters for mature specimens) and their tendency to spread laterally.

Soil and plantation

• Ideal soil: Calcareous, deep, loose, with good drainage and a moderate presence of organic matter. The substrate should allow water to pass through easily to prevent waterlogging.
• Plantation: It is best to plant it in autumn, to promote better rooting before spring.
• Compatibility: Although cedar tolerates other types of soil, excellent drainage is essential.

Irrigation

In the early life (up to 4 years), the ornamental cedar requires frequent waterings to properly establish its root system. Once established, watering can be spaced out as tolerates periods of drought Much better than overwatering. A good guideline is to water deeply and let the soil dry between waterings.

El excess irrigation It is one of the most frequent causes of problems, since it causes root rot and fungal development.

Subscriber

• Early spring: It's time to contribute mature manure o compost around the base of the tree.
• Cedrus deodara: It is also recommended to fertilize at the beginning of autumn to promote growth and resistance. Tips for choosing ornamental trees.

Avoid overfeeding established plants, as ornamental cedar is a slow feeder and does not require intensive nutrient input.

Pruning

La pruning is not necessary under normal conditions. This should only be done to remove dry, damaged, or malformed branches. Occasionally, if you want to control their size or shape, light pruning is possible, preferably in late winter.

Species-specific care

Care of Cedrus libani (Lebanon Cedar)

• Exhibition: It prefers full sun and is resistant to sporadic, but not constant, frost.
• Irrigation: More frequent in the first years, progressively decreasing after 3-4 years.
• Ground: Calcareous, deep, well-drained, with organic matter.
• Pruning: Sanitation only.
• Subscriber: Manure in spring.
• Spread: By means of seeds sown in spring, although it is most practical to purchase well-formed nursery specimens.

Care of Cedrus deodara (Himalayan Cedar)

• Exhibition: Full sun, semi-shade or light shade.
• Ground: It prefers non-calcareous, well-drained soils.
• Irrigation: Moderate watering throughout the year and allow the soil to dry before the next watering.
• Subscriber: Add organic matter in autumn.
• Pruning: Only to remove damaged or dry branches.
• Spread: From seeds in spring, transplant when they are more than two years old.

Prevention and treatment of pests and diseases

The ornamental cedar is resistant to most common pests garden, but there are risks if the conditions are not optimal, especially due to excess moistureThe main problems and solutions are:

• Fusarium and Phytophthora: Fungi that affect roots and trunks, caused by excess moisture. The best prevention is to ensure rapid drainage and avoid overwatering. Tree diseases and how to prevent them.
• Aphids and mealybugs: They attack tender shoots, especially young plants. They can be treated with potassium soap or neem oil. Use of shavings for plant protection.
• Pine processionary moth and other lepidopterans: They can occasionally be affected, especially when they are near pine forests. Manually removing nests and protecting them with biological traps is the most effective way to prevent nests from spreading.

La prevention It is the best tool: choose healthy varieties from trusted nurseries, check soil moisture, and provide quality organic matter.

Reproduction and multiplication of ornamental cedar

La propagation The ornamental cedar is mostly made from seeds:

• Harvesting ripe pineapples: The pine cones remain on the tree for one to two years.
• Spring sowing: Use a light substrate and keep it moist, but never overly soggy; germination is usually slow and requires patience.
• Young seedlings: Keep young plants in a protected location for the first two years before planting them in their final location.

Due to its slow growth and sensitive juvenile stages, it is recommended to purchase already developed specimens from specialized nurseries.
