Lithocarpus edulis, the Japanese stone oak, is a species of stone-oak native to Japan. It is an evergreen tree growing up to 15 metres tall. The nuts are edible for people but taste bitter. The nuts contain tannins, however soaking them in water removes them. It is cultivated as an ornamental plant.
Japanese stone oak is resistant to disease and generally not susceptible to illnesses. In terms of care, this species is fairly low-maintenance. When grown outdoors it needs only minimal watering, and larger plants typically do not require pruning. Smaller plants, however, should be pruned after they finish blooming. Japanese stone oak is appropriate for anyone with outdoor space, such as a garden or a deck, and does not demand extensive plant-care experience.
How to keep Lithocarpus Edulis.
Light
Japanese stone oak is native to open habitats, such as sunny meadows and the edges of forests, which offer abundant light. It grows best in Full Sun but can endure Partial Sun, adjusting well to a range of sunlight conditions.
Water
The Japanese stone oak thrives best in moderately humid environments and needs consistent moisture without becoming waterlogged. To care for this plant, water it every 2-3 weeks, allowing the soil to dry slightly between watering sessions. It flourishes outdoors in well-draining soil, as this emulates its natural woodland habitat where rainfall varies with the seasons.
Temperature
The Japanese stone oak is highly adaptable to a range of climatic conditions, from very hot summers to cold winters. Still, it has a preferred temperature band for healthy growth. If temperatures get too high, the plant can suffer from heat and humidity stress, which may kill it. In areas where temperatures reach the lower edge of its cold tolerance, taking insulating measures to protect the plant is advisable.
Fertilizer
To encourage healthy growth, feed your Japanese stone oak in early spring. Routine fertilization boosts its overall health, producing vigorous growth, increased toughness in difficult conditions, and enhanced resistance to pests and diseases. Follow a consistent fertilizing routine to maintain bright foliage with deep color and a full, lush look.
