How to Use This Calculator

How to Use This Calculator

  1. Choose imperial or metric units with the toggle.
  2. Enter the total area you want to xeriscape.
  3. Enter the average spacing between plants (e.g. 0.5 m or 1.5 ft).
  4. Enter your desired mulch depth (5–10 cm / 2–4 in is typical).
  5. Add the estimated cost per plant and the cost of mulch per unit volume.
  6. Pick your currency for a localised cost estimate.

Tips

  • Group plants by water needs and allow for their mature size when choosing spacing.
  • A mulch depth of 5–10 cm (2–4 in) suppresses weeds and conserves moisture.
  • Gravel or rock can be used instead of organic mulch in very dry climates – just adjust the mulch cost.
  • Remember to budget separately for landscape fabric or irrigation if needed.

Common Questions

What is plant spacing and why does it matter?

Plant spacing is the distance between each plant. Proper spacing ensures healthy growth, reduces competition for resources, and helps achieve full coverage in your xeriscape.

How deep should mulch be for xeriscaping?

A depth of 5–10 cm (2–4 in) is generally recommended. This suppresses weeds, conserves moisture, and insulates the soil effectively.

Can I use gravel instead of organic mulch?

Yes, gravel or rock can be used as mulch in xeriscaping, particularly for very dry climates. Adjust the 'mulch cost' input to reflect your chosen material.

Are there ongoing maintenance costs with xeriscaping?

Xeriscaping requires less maintenance than traditional lawns but may still need occasional weeding, pruning, and mulch top-ups.

Does xeriscaping increase property value?

Well-designed xeriscapes can boost kerb appeal and property value, especially in regions where water conservation is valued.

Can I use this calculator for any country?

Yes, simply switch between metric and imperial units and adjust the currency and material costs to match your local prices.
