Cuidados

Oaks need plenty of space to reach their full potential. Keep the area around the base clear of debris and mulch lightly to retain moisture. Watch for signs of leaf spot or pests like scale during the growing season.

Watering

Young trees need regular watering until established, but mature oaks are quite drought tolerant.

Feeding

Apply a slow release balanced fertilizer in early spring if growth seems sluggish.

Pruning

Prune during winter dormancy to remove dead or crossing branches.

Repotting

Oaks are not suitable for container life long term and should be planted in the ground.

Seguridad

People

The leaves and acorns contain tannins which can cause digestive distress if ingested in large quantities.

Pets

Acorns and leaves contain tannins that can cause digestive upset if ingested by pets.

Children

Acorns are a choking hazard for small children and should be kept out of reach.

Contact allergens

Some people may experience mild skin irritation from handling the rough bark or leaves.

Airborne allergens

Oak pollen is a significant airborne allergen during the spring flowering season.

Edibility

Acorns contain high levels of tannins that must be leached out before they are safe for human consumption.

When to plant

spring, autumn

Overwintering

Oaks are generally hardy and require no special winter protection once established in the landscape.

In containers

Oaks are generally not suitable for long term container growth due to their extensive root systems.

Planting native woodland perennials under the drip line of an oak creates a functional ecosystem that mimics the forest floor.
