I planted three Quercus robur acorns in the late 1990's that came from the Auckland Domain Park on the North Island of New Zealand. Two of these acorns are now 15' and 20' tall English Oaks growing in Western Pennsylvania.
The Auckland Domain Park is the cites oldest park and was formed by a 140,000 year old volcano. Mature trees are found throughout this impressive Park. Many of the trees were planted in the 1840's and now have developed into the initial site of Auckland's Botanical Gardens.
The English Oak is a stately tree and requires an extra large yard to grow one. It is most often used in public parks and gardens. The English Oak tolerates a wide range of soils from acidic to alkaline. A moist silt loam with good drainage is preferred. The tree does not transplant eas... read more

Grows fairly well in sub tropical Brisbane. Although doesn't live as long as if gown in a cool climate. Have had mine 2 years or so. Loses most leafs in dry season but only goes dormant for a week and starts growing again in late winter. Great tree except seems to be a favourite of leaf miners. Handles our harsh sun well. Even in mid summer when uv can get to uv index 14 - 16 it doesn't get burnt. Amazingly hardy and adaptable. Temperatures here range from 20 - 24c in winter (dry season) and 30c - 35c in summer (wet) although has been fine through extremely hot weather at 44c.

The Oak is the dominant hardwood tree in Britain, but it needs deep, rich soil to grow to full size. Wood is very hard and strong and was much used for shipbuilding in previous centuries, many of the ancient oak forests in Britain were cut down for this purpose.

I like this tree a lot! I like oaks in general. This one is pretty common here in Argentina. Perhaps because of all the European Immigration we had.
I would like to notice one thing about this tree. Almost every year the leaves get white stains that look like fungus and also a sticky stuff. Does any of you guys have an idea about what it is and how to treat it? I'm asking you, Palmbob! You seem to know a LOT, so... please give me an advise!

When we built our new home, one of our neighbors - a professor of horticulture, gave us a potted 1 foot tall English Oak. That first winter I still hadn't decided where to put it because it was so small, I was afraid we'd run over it with the mower by mistake, so I took it out of it's pot and stuck it in the remnants of a manure pile to overwinter. By next spring it was showing signs of being extremely happy where I'd put it so I decided to leave it where it was and build a garden for the time being around it. Seven years later it's doing quite nicely and is approximately 12' tall. While it hasn't taken on the wondrous appearance of some of the old oaks I've seen, I'm just happy that it's doing well. I was told that the english oak can have a life span of 600-700 years. It'll sure o... read more

Massive tree that goes leafless briefly, at least here in Southern California. Has a mound profile from a distance- too large for most private gardens- creates a dark shade. Wood often used for construction.
