USES

Quercus suber is a good option for:

  • Cold areas where olive tree doesn’t resist.
  • Rocky terrain.

Ideal species to not create an excessive shade. Its shadow is light, considering that even having perennial leaves it doesn’t form a dense crown.
Excellent plant for frequented places (people, animals, etc), thanks to cork bark protection.

LOGISTIC AND MAINTENANCE

  • Easy handling thanks to protection that bark offers, that allows the plant to be held up directly from the trunk when cranes are employed for transplanting.
  • Maintenance: excess of humidity in the soil doesn’t help it. It tolerates very well Mediterranean climate dryness and it keeps in good health with low level of nutrients, and consequently it doesn’t need large supply of fertilizers.
  • It well put up with drastic pruning.

PRECAUTIONS

  • Abstain from very chalky soils.
  • Sores and diseases:
    • Pathologies due to funguses: It is sensitive to Phytophthora and to Diplodia. A preventive treatment with fungicides during the transplanting is recommended.
    • Insects: Coraebus undatus is a driller that coexist with Quercus suber without causing serious damages. An insecticide treatment against the adult insect is feasible.

CURIOSITIES

  • Inside its roots the mushroom Boletus edulis, well-known as white mushroom and of a high gastronomic value, set mycorrhiza up.
  • Bark is the raw material used to produce cork bottle caps.
