Patio Tree

[Audrey P]

We live in South West France. normally we get temperatures of up to 3

degrees C in summer, and short periods of minus 9 to 12 degrees C i winter. We have had a patio consturcted and have left a one metre diameter hol for a tree to be planted to give some shade. The patio is laid on on foot of reinforced concrete, and underneath that there is solid clay which in the hole makes water very slow draining. We have been advise that the tree roots may rise and distort the patio in time. Is thi likely to happen? If so, what type of shrub or small tree would thriv in these conditions without endangering the patio? We would be most grateful for any suggestions

Do you prefer deciduous or evergreen?

[Steve]

A Japanese maple will fit in the hole and do quite well.

[Audrey P]

We have no preferences

If you plant the tree too deep the woody roots will often come up and become surface roots.

SEE THE FOLLOWING FOR PLANTING so, what type of shrub or small tree would thrive

How big is your patio? Do you have room to make a big pot? I can give some suggestions for a big pot. The pot has to be big.

Beware of so-called tree experts who do not understand tree biology. Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us that we are not the boss.

Consider one of the Japanese maples. It would provide year-round interest, something important in such a spot. Japanese maples are very well-behaved in such situations and can take the drainage issues you may have, up to a point.
