Soil pH and why it’s important
An important starting point for improving your soils health, is to determine it’s pH. This indicates the soil acidity, or alkalinity on a scale of 1 to 14. Alkaline soils have a pH of higher than 7 and acidic soils a pH of lower than 7 and Perth’s sandy soil, typically ranges from a pH of 4 to 8.5. You can test the pH of your soil either by using a soil pH test kit, which can be purchased at most garden centres, or if you want to get really scientific, you can also take a soil sample to a local laboratory for testing. Once you have determined your soils pH, you can make a start of establishing the optimum pH level for plants, which is generally within the pH range of 5.5 to 7.5. For acidic soils an application of dolomite lime at 100 grams per metre squared, can be used to increase the soil pH by 1 point. Patience is a must for this type of application, as it can take several months to take effect. In alkaline soils, iron sulphate can be applied to decrease the soils pH level (refer to instructions regarding quantities) and is almost instant, in contrast to the dolomite lime application.
Keeping water and nutrients in your sandy soil
Another common issue with sandy soils is water and nutrient retention. Effectively addressing this, will help to increase the overall health of your plants, decrease the amount of watering required and hinder the harmful effects of excessive nutrients leaching into the groundwater system and fragile ecosystems beyond. Organic materials, fine mineral particles and water absorbent gels, are all great ways to combat poor water and nutrient retention. Organic materials including composts, coco peat and broken down animal manure, are all beneficial soil additives. However, when these types of materials become dry, they may also become water repellent. Plant residues, either dry or green, can also be beneficial, but it is vital that these are well composted prior to application, or your plants may be susceptible to disease. Clay, loam and red mud, also known as finer particles, are also great in boosting water and nutrient retention, with the ideal clay content in soil being 5 to 10 percent.

- I used Luke’s Landscaping to provide an overhaul of my front lawn with the task to reduce the amount of lawn and increase the low maintenance area including a rock feature. Also, they were used to provide a major landscaping overhaul for my Daughter’s back garden including lawns, garden beds and low water usage reticulation. All work was carried out within the agreed time schedule. The staff are very accommodating and pleasant to deal with. The work completed with efficiency, and all aspects were well-coordinated.

Our front yard in Karrinyup was completely transformed in March 2015. In just one week, the team completed the job of removing what was there, replaced the topsoil, installed the reticulation and mulched with native plants. Four months on we are still so impressed with the job and delighted that we used Luke’s Landscaping. Highly recommended!
