Pin oak

Landscape Uses:Aggressive surface roots possible, Specimen, Street tree. Prefers a good deep fertile loam which can be on the stiff side[1, 11]. Lime tolerant. Young plants tolerate reasonable levels of side shade. Withstands atmospheric pollution. Tolerates moderate exposure, surviving well but being somewhat stunted. A fairly fast growing tree, it is occasionally cultivated for timber in eastern central Europe. It coppices fairly well. The tree seldom lives longer than 150 - 200 years in the wild, commencing to bear seeds when 15 - 25 years old. Seed production is cyclic, a year of high yields being followed by 2 - 3 years of low yields. The tree flowers on new growth produced in spring, the seed taking two summers to ripen. There are some named varieties selected for their ornamental value. Intolerant of root disturbance, trees should be planted in their permanent positions whilst young. This species has a relatively shallow tap-root, making it easier to transplant. Hybridizes freely with other members of the genus. Plants in this genus are notably resistant to honey fungus. Special Features: Attracts birds, North American native, Inconspicuous flowers or blooms.

Edible Parts: Seed Edible Uses: Coffee Seed - cooked. The seed is about 15mm long, it can be dried, ground into a powder and used as a thickening in stews etc or mixed with cereals for making bread. The seed contains bitter tannins, these can be leached out by thoroughly washing the seed in running water though many minerals will also be lost. Either the whole seed can be used or the seed can be dried and ground it into a powder. It can take several days or even weeks to properly leach whole seeds, one method was to wrap them in a cloth bag and place them in a stream. Leaching the powder is quicker. A simple taste test can tell when the tannin has been leached. The traditional method of preparing the seed was to bury it in boggy ground overwinter. The germinating seed was dug up in the spring when it would have lost most of its astringency. The roasted seed is a coffee substitute. References More on Edible Uses

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. Average germination rate is about 68%. 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. Trees should not be left in a nursery bed for more than 2 growing seasons without being moved or they will transplant very badly.
