Growth of roots

United Kingdom Gb

My neighbour informed me that the roots of my Acacia Dealbata would spread approx three times the height. Is this true?


On plant Acacia dealbata

Depends who you talk to. We were told, when training, that it would be beween 2 and 3 times the height of the tree, or as wide as the crown. This means, though, that some of the roots will go down very deep (foundations might be at risk) and others spread out sideways, and as to what any individual plant is actually going to do in terms of root spread can be variable - depends on the water supply to a large extent. As you've got a smallish tree there, it shouldn't be planted too near a house or building anyway.

as a basic rule of thumb there will be about as much root bye volume as tree and bye nature the tap root will keep comming down till it hits the water table which can be very deep.other outward roots are for feeding and support .pine trees have quite small root balls as they rely on being in forests for support and there isnt much greenery above.being in a forest all the nutrients and water are at the surface.this is why cutting down jungles is so devistating as all your left with is lifeless sandy soil.trees that stand alone like a big oak weigh maybe upwards of 10-20 tons of wood to support in the wind to and rain

One point is if the roots near the surface are damaged, then they will sucker and you will have shoots coming up that are difficult to 'get rid of'
