Ivydene Gardens Plants:
Plants for Chalky Soils List

Soil over chalk and limestone is almost invariably alkaline (Limy). It is usually fairly fertile, but can be shallow and consequently dries out quickly. In such cases, use drought-tolerant plants, such as ones that grow in dry soil conditions (see plants in the Dry section of the Moisture column of the soil type, aspect and moisture list page).


Chalk and Limestone Gardening by Sarah Coles (ISBN 1 86126 738 X) shows how to improve the soil and which plants flourish on alkaline soils - chalk and clay.

 

Action to assist in Chalk soil maintenance:-

  • Mulch the beds with a 4 inch (100mm) deep layer of Spent Mushroom Compost to improve fertility and drainage; preferably in the Autumn in between the existing plants, and top it up each year after that. This will stop the chalk soil from drying out through the action of sun and wind on its surface, and to provide chalk and carbon to aid in soil formation and fertility.
  • If starting a new lawn or bed, rotovate the wet chalk soil, add the 4 inch layer of Spent Mushroom Compost mulch and rotavate that in. Heel and rake the ground for a new turf (or to be seeded) lawn, before laying or seeding it. Insert plants in new bed, before installing the irrigation system and then applying a 4 inch layer of this mulch on top of it.
  • Mow the existing lawn closely before spreading a 1/4 inch (6mm) deep layer of any sand (Kiln dried Top Dressing is easier to spread, both available from Gardenscape in small bags or in 1 tonne bags) over it, starting in late April. Repeat this each month until July for one season. This will improve the fertility of the lawn by providing silica in the form of sand (See What is Soil Texture Page in the Soil Section for further details). Spreading the same depth of sand on the flower/vegetable beds at the same time would also be beneficial.

 

Chalky Soil is Alkaline on the pH scale. The garden use list is sorted in the following table under the following height of plant range:-

Below 2 feet in height
Between 2 and 6 feet in height
Above 6 feet in height
