For general notes on lime see ALLOTMENT. It must be emphasised again that heavy dressings of lime are generally unnecesary unless a soil test indicates a deficiency, although lime is a great help in breaking up intractable clay soils. Lime should be worked into the top 3 or 4 in. of soil, rather than left on the surface, as sometimes recommended.
The following (among others) will not grow freely where lime is present.
— Eucryphia glutinosa — Gentiana sino-ornata — grevillea — kalmia — Lithospermum dijfusum (prostratum), but NOT other species of this genus — lupin — most ericas except a few species like carnea and E. darleyensis (mediterranea hybrida) — practically all and azaleas. Strawberries do not thrive on soils with a very high lime content. Nursery catalogues usually indicate plants disliking lime.
Note that most plants which succeed on limy soils do as well on land which is lime-free. Most, shrubs, fruits and vegetables are, in fact, lime-tolerant despite the important exceptions noted above. The following are some of the plants which give particularly good results on land with a high lime content. When the soil is slightly acid it is often helpful to add lime for plants like Lilium candidum and scabious which demand lime or chalk for really heavy crops of bloom. Aethionema — Arbutus unedo — Convallaria majalis (lily-of the-valley) — carnations — clematis — gypsophila — iberis (candytuft) — iris (with a few exceptions, notably Kaempferi) — lavender — Lilium candidum — lithospermum (except L. dijfusum) — pink— romneya — rose — scabious — sweet william — wallflower — cabbages, turnips, peas and beans — peaches, plums and cherries.
