Types of Garden Soil

ACID

Such a soil will be of high acid reaction. It will be well-drained in winter and be retentive of moisture in summer but unless some preparation is done to counteract the acidity, it will grow only a limited range of plants. A load of heavy loam, sometimes to be obtained from a building site will do much to correct the acidity of the black peat soil. Slow-acting fertilisers such as shoddy, fish waste, seaweed and farmyard manure should be incorporated but all fertilisers of an acid nature should be omitted. A heavy dressing of lime each year will enable a wider selection of plants to be grown but this must be omitted where growing only those plants requiring acid conditions such as the following:

Calhma vulgaris, Hamamelis mollis, Camellia japonica Kalmia latifolia, Clethra acuminate, Lindera benzoin, Cyrilla racemiflora, Liquidambar styraciflua, Daphne mezereum, Magnolia macrophylla, Desfontainea spinosa, Vemettya mucronata, Embothrium coccineum, Pieris floribunda, Enkianthus perulatus, Rhododendron (including Azalea), Erica, Vaccinium corymbosum, Fothergilla gardenia, Zenobia pulverulenta, Gaultheria fragrantissima

CALCEREOUS

Calcareous soils are found south of the Thames, especially in the regions of the Chiltera Hills and South Downs. Similar soils are found in the Cotswolds whilst limestone formations cover the north of England from a line drawn from Barrow-in-Furness to Flamborough Head. These are the most difficult areas in which to garden for they are exposed to strong winds whilst the soil will usually lack depth. Also, the soil will contain seventy per cent silica and will usually be dry and hungry though on the credit side, there will be no fear of losing plants through excess moisture during winter. Green manuring will increase the depth and add to the humus content whilst decayed manure, fish or bone meal (at the rate of 4 oz per sq. yd.) will provide nitrogen which a limestone soil will almost always lack. In addition, any humus forming materials such as peat, used hops or poplar bark fibre should be dug in when the ground is prepared. Indeed, any materials should be added which will increase the depth of soil and to ensure that it will be cool in summer.
