Can reach heights of up to 25m in its native Central and Southern Europe. Fully hardy as an ornamental tree, Turkey Oak requires some protection from hard frost when grown as bonsai.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\"><b>Quercus petraea\/ Sessile Oak<\/b>\u00a0Closely resembles the English Oak Q.Robur but has longer leaves of between 6-17cm. Commonly reaches heights of 30m in mainland Europe. Fully hardy but needs protection from hard frost when grown as bonsai.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\"><b>Quercus robur\/ English Oak<\/b>\u00a0Slow-growing and long-lived deciduous tree. Lobed leaves are yellow-green in Spring turning to bronze in Autumn up to 5-15cm long with very small stalks.<\/p><p style=\"font-family: 'myriad pro'; font-size: 16px; font-style: normal; font-weight: 400;\">There is much hybridization between Q.Robur and Q.petraea found growing in Europe. Height to 35m.<\/p><p><span style=\"font-family: myriad pro;\"><b><u>BONSAI CULTIVATION NOTES<\/u><\/b><\/span><\/p><p><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"><b>POSITION: <\/b>Full sun and good air circulation. Protect from hard frost below -5\u00b0C. Shaded branches on Oak bonsai have a tendency to die-back.<\/span><\/p><p><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"><b>FEEDING:<\/b> Every two weeks at half strength after first growth has hardened off in Spring.<\/span><\/p><p><b style=\"font-style: inherit; font-family: 'myriad pro'; color: var( --e-global-color-text );\">REPOTTING: <\/b><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\">Standard practice says that Oak should be repotted yearly as buds start to move in Spring until the tree is 10 years or older, then every 2-3 years.\u00a0 <\/span><\/p><p><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\">Repotting after the first leaves have opened or in early Autumn is better for Quercus robur\/English Oak.\u00a0<\/span><\/p><p><b style=\"font-style: inherit; font-family: 'myriad pro'; color: var( --e-global-color-text );\">PRUNING:<\/b><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"> Trim new shoots and pinch out apical buds unless extension is required.<\/span><\/p><p><b style=\"font-style: inherit; font-family: 'myriad pro'; color: var( --e-global-color-text );\">DEFOLIATION:<\/b><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"> Complete defoliation can result in larger leaves and on weaker trees, dieback of lower branches. Infrequent repotting helps reduce leaf-size, as does removal of apical\/terminal buds before they extend in Spring.<\/span><\/p><p><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\">I have had very good results from regular removal of all large leaves (except those on the weakest branches) and thinning of the foliage at the tips of branches. The tips of most Oak branches will produce a swirl of 4,5 or more leaves, remove all but the smallest to prompt creation of a new flush of smaller leaves.<\/span><\/p><p><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"><b>PROPAGATION:<\/b> Sow seed outside as soon as ripe. Air-layering with difficulty.<\/span><\/p><p><b style=\"font-style: inherit; font-family: 'myriad pro'; color: var( --e-global-color-text );\">PESTS AND DISEASES:<\/b><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"> Very susceptible to mildew problems unless good air circulation is provided, also oak wilt, aphids and gall wasps.<\/span><\/p><p><b style=\"font-style: inherit; font-family: 'myriad pro'; color: var( --e-global-color-text );\">STYLING:<\/b><span style=\"font-size: 16px; font-family: 'myriad pro'; color: var( --e-global-color-text );\"> Upright and slanting styles, multi-trunk styles, group planting in medium to large sizes. Suitable for subtle deadwood features.<\/span><\/p><p><b style=\"font-style: inherit; font-family: 'myriad pro'; color: var( --e-global-color-text );\">POTS:<\/b><span style=\"font-size: 16px;
