  • skullToxicity

    • To humans

      Quercus rysophylla, commonly known as Loquatleaf Oak, is not commonly listed as a toxic plant to humans. Oaks can produce tannins, which in large amounts may cause stomach upset, nausea, vomiting, or diarrhea if ingested in significant quantities, but generally, they are not considered poisonous to people. It is, however, always recommended to exercise caution and not consume parts of ornamental plants unless they are known to be safe for consumption.

    • To pets

      Quercus rysophylla, known as Loquatleaf Oak, has parts that are potentially toxic to pets, specifically to cats, dogs, and horses. The ingestion of acorns or oak leaves in significant amounts can cause poisoning due to the tannins present. Symptoms of Oak poisoning in pets can include vomiting, diarrhea, abdominal pain, reduced appetite, and kidney damage in severe cases. Ingesting small quantities typically only results in mild gastrointestinal upset, but consumption of large amounts requires veterinary attention.

  • water dropWater

    The Loquat-leaf Oak should be watered thoroughly when the top 2-3 inches of soil feel dry to the touch. During the growing season, it may need watering approximately once a week, but always check the soil moisture before watering. The amount of water needed at each watering can be about 1-2 gallons for a young tree, increasing as the tree matures and depending on the size and root system. In the winter, reduce watering frequency as the tree’s growth slows down. Ensure that the water penetrates deeply into the soil to encourage a robust root system.

  • sunLight

    The Loquat-leaf Oak prefers full sun to partial shade conditions. It thrives best when planted in a location that receives at least six hours of direct sunlight daily but can also tolerate some light afternoon shade.

  • thermometerTemperature

    The Loquat-leaf Oak is adapted to a range of temperatures but grows best in conditions between 50°F and 80°F. It can survive minimum temperatures down to 20°F, but growth may be stunted or damaged if temperatures fall below this point. It is important to protect the tree from extreme cold and frost.

  • scissorsPruning

    Pruning the Loquat-leaf Oak is important for maintaining tree health and structure, and should be done in late winter before the spring growth starts. Remove any dead, damaged, or diseased branches, as well as any that cross or rub against each other. Pruning every 2-3 years is typically sufficient unless there are specific structural issues that need to be addressed more frequently.

  • bambooSoil

    The best soil mix for the Loquat-leaved Oak (Quercus rysophylla) should be well-draining and rich in organic matter, such as a blend of loamy soil with compost and coarse sand or perlite. The ideal pH range for this oak is slightly acidic to neutral, between 5.5 and 7.0.

  • plantRepotting

    Loquat-leaved Oaks require repotting every few years, typically when they become root-bound or the soil is exhausted. However, as a large tree, Quercus rysophylla is more commonly transplanted less frequently, especially when it is planted in the ground.

  • circleLife cycle

    Quercus rysophylla, commonly known as Loquat-leaf Oak, begins its life cycle with the germination of acorns that have been dispersed by wildlife or gravity. Upon sprouting, the seedling emerges with a taproot, which anchors the plant and absorbs water and nutrients from the soil. As the young oak sapling grows, it develops a woody stem and a branching structure, forming a broad, rounded canopy with large, glossy, leathery leaves characteristic of this species. Throughout its maturation, the Loquat-leaf Oak becomes more drought and frost-resistant, adapting to a wide range of environments. Once mature, which can take several years, it produces catkins which are wind-pollinated, leading to the development of new acorns. These acorns, when mature, fall to the ground to start the cycle anew or are carried off by animals, facilitating the spread of the species.

      Spring to Summer

    • The most popular method of propagating Quercus rysophylla, commonly known as Loquat-leaf Oak, is by seed. The ideal time to sow the acorns is in autumn, shortly after they have matured and fallen to the ground. It's essential to plant them immediately as the seeds do not store well and lose viability quickly when detached from the tree. Acorns should be sown in a well-draining soil mix, at a depth of about 1-2 inches (2.5-5 cm) and spaced adequately to allow for growth. Typically, the seedlings emerge in the spring. Care should be taken to maintain a moist soil environment until germination without waterlogging, which could lead to rot. Seedlings are usually ready to be transplanted to their permanent location after one or two growing seasons.
