Private individuals can buy from our selection of species tolerant of extreme pH here.

It is important to select the correct species when the destination soil exhibits extreme pH, either high alkalinity or acidity.

There are a number of species that are extremely tough growers and as such are able to tolerate extremes in pH. Extreme pH affects a trees ability to absorb nutrients and can cause stress, predispose the tree to disease and ultimately lead to failure.

Barcham recommend the following trees to tolerate soil extreme pH:

Betula pendula

Populus tremula

Quercus cerris

Sorbus intermedia

Sorbus thuingiaca Fastigiata

For species that tolerate acidic conditions, see the extended list.

For species that tolerate alkaline conditions, see the extended list.
