Plants for Different Soil Types

 

 

 

 

 

 

Knowing your soil type can be crucial to planning out the planting in your garden. The soil provides your plants with nutrients, water and air that they need for healthy growth and development, but depending on the plot of ground, that can determine what plants, shrubs or trees can grow their successfully.

3 Step System to Test Your Soil

  1. Dig a hole 6 to 10 inches deep in the soil.
  2. Separate an intact section about the size of a soup can and break it apart with your fingers.
  3. Determine whether the soil is cloddy, powdery or granular (ideally your soil should be made up of different sized crumbs that hold their shape under slight pressure).

 

  • Known as heavy soil (sticky when wet, rock hard when dry).
  • Feels smooth (not gritty) between the fingers.
  • Drains slowly after rain.
  • Takes a long time to warm up in spring.
  • Heavy to dig and cultivate.
  • Usually rich in plant nutrients.The following plants are well-adapted to clay soils:
Viburnum
Viburnum burkwoodii Mohawk

This shrub is an underrated evergreen shrub for clay soil. The opening of its flowers announce the end of winter and its white flowers (pink in bud) provide a pretty backdrop for a border in early spring. Dense, compact growth make this a useful plant for screening off a view and creating a feeling of enclosure in the garden.

Honeysuckle
Honeysuckle Serotina

A sweetly scented honeysuckle is a true summer treat and this species of honeysuckle will grow well on clay soil. A scented climber is always a memorable plant, the perfume easy to access, especially if you grow it by your front door. The variety Serontina’ has flowers that display a vivid deep red colouring.

 

Bergenia
Bergenia cordifolia Purpurea

This evergreen perennial produces spires of pink or red flowers in spring. The leaves (the ‘elephant’s ears’) are tinged with red in winter. A good plant for ground cover, it looks at its best planted in a block because the flowers have more impact in big numbers. A very tough plant for clay soil and tolerant of partial shade too.

 

 

Tips 

  1.  Add Organic Matter (compost, aged manure) – this helps improve drainage, lighten heavy soil and adds nutrients. Before planting in spring add the organic matter to the soil with a 2-3 inch layer.
  2. Build Raised Beds – As clay soil holds water, raised beds can improve drainage by encouraging water to run off.
  3. Mulch Beds over Winter – Mulch with organic matter during the growing season and winter to help protect the soil from compaction and minimize weed growth.

Sandy soil is the largest particle in soil and does not hold nutrients well.

  • High proportion of sand and little clay.
  • Drains quickly after rain or watering.
  • Easy to work and cultivate.
  • Warm up quicker in spring than clay soils.
  • Low in nutrients – very acidic.

The following plants are well-adapted to sandy soils:

Sedum
Sedum Hot Stuff
