Safety & Hazards

All parts of the plant contain tannins. Whilst tannins are found in many foods, and have a range of medicinal uses. They are usually only present in low concentrations. In some foods made from oaks (particularly the seeds), the tannin content can be quite high unless the food is treated to reduce tannin content. Tannins are only of low toxicity and, because of their bitter taste and astringency, are unlikely to be eaten in large quantities. However, if they are taken in excess, they can cause stomach pains; constipation followed by bloody diarrhoea: excessive thirst; and excessive urination[1].

Cultivation Details

HabitDeciduous Tree
Growth—

Quercus serrata is a very cold-hardy tree, tolerating temperatures down to around -25°c when dormant. It grows best in areas with hot summers. In areas with cooler summers (even where the winters are mild), such as the maritime regions of the temperate zone, it often grows poorly, failing to properly ripen its wood and suffering frost damage over the winter[2, 3]. Prefers a good deep fertile loam which can be on the stiff side[4, 2]. Young plants tolerate reasonable levels of side shade[3]. Tolerates moderate exposure, surviving well but being somewhat stunted[3]. Trees are often coppiced in China[5]. The seed takes two growing seasons to ripen[6]. Seedlings soon develop a taproot and become intolerant of root disturbance, they should be planted into their permanent positions whilst young[2]. Hybridizes freely with other members of the genus[3]. Plants in this genus are notably resistant to honey fungus[3].

Propagation

Seed - it quickly loses viability if it is allowed to dry out. It can be stored moist and cool overwinter but is best sown as soon as it is ripe in an outdoor seed bed, though it must be protected from mice, squirrels etc. Small quantities of seed can be sown in deep pots in a cold frame. Plants produce a deep taproot and need to be planted out into their permanent positions as soon as possible, in fact seed sown in situ will produce the best trees[2]. Trees should not be left in a nursery bed for more than 2 growing seasons without being moved or they will transplant very badly.
