Quercus castaneifolia
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
Quercus castaneifolia is a moderately cold-hardy tree, tolerating temperatures down to around -20°c when dormant. It grows best in areas with hot summers, but is also very tolerant of cooler and moister summers - a specimen at Kew Gardens, London, England (hardiness zone 7 - 8) is more than 30 metres tall[2]. Quercus species generally grow well in a sunny position, though young plants usually tolerate reasonable levels of side shade[3]. They usually prefer a good deep fertile loam which can be on the stiff side[4, 2]. They are also often tolerant of moderate exposure, surviving well but being somewhat stunted[3]. The seed takes two growing seasons to ripen[2]. Seedlings soon develop a taproot and become intolerant of root disturbance, they should be planted into their permanent positions whilst young[2]. Most Quercus species hybridize freely with other members of the genus[3]. Plants in this genus are notably resistant to honey fungus[3]. One of the most widely distributed forest species of Talysh, . In the south of the USSR where it is to be found occasionally in cultivation (Crimea, Ukraine); it deserves considerable extension[5]..
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.
