Hello June! Our plant of the week this week is the hydrangea, one of our staples in Louisiana. Most bigleaf hydrangeas are sensitive to the PH of the soil, and will change the color of their petals depending on the acidity. For blue petals, the soil needs to be acidic (below a pH of 6). For pink or red blooms, you’ll need with a PH over 7. Neutral or slightly acidic soil will give you purple flowers! If you want to increase the PH of the soil for pink blooms, you can add mineral lime to it. Adding sulfur to the soil will decrease the PH. If you have any questions, let us know!
