What is Soil pH? Soil pH tells you the acidity or alkalinity of the soil. A pH of 3.5 is highly acidic and 9.0 is extremely alkaline. Roses prefer a soil pH closer to the middle, around 6.5.
Can roses grow in alkaline soil?
The optimal soil pH for growing roses is slightly acidic with a pH between 6-7 with a pH of 6.5 considered ideal. If the soil is too acidic (lower then pH 6) or too alkaline (higher then pH 8) the roots of the rose will have difficulty absorbing essential nutrients and the rose will likely die.
How do I make soil more acidic for roses?
When you mix elemental sulfur into the soil, bacteria break it down and in the process create sulfuric acid, which reduces the soil pH and increases soil’s acidity immediately. This process is best accomplished before planting so you can retest the soil in four to five months.
Does rose like acidic or alkaline soil?
The correct pH level of our garden soil makes a huge difference to the health of our plants, with most plants growing best in slightly acidic to neutral soil (a pH between 6 and 7). The ideal pH for roses is a soil that tests between 6 and 6.5.

What happens if soil is too alkaline?
When soil pH is too high, it can pose problems for plant health and growth. For many plants, soil that is high in alkalinity makes it harder for plants to drink in nutrients from the soil, which can limit their optimal growth.
