I have routed my bathtub water to the front of my house where my once beautiful hydrangeas were. After a month of greywater usage the hydrangeas leaves have turned from green to dark brown around the edges and have shrimbled. Any thoughts on this matter would be great.
My first thought would be the plants received either too much or too little water. Too much water could cause the roots to become waterlogged.
Any issue with salt or boron in the water would take much longer than a month to affect the plant (assuming you were using the “wrong” products in the shower). I would check the soil moisture levels. Also, be sure to water near the “drip line” of the plant- where the branches end. You shouldn’t put too much water near the base of the plant.
I know of other hydrangeas successfully irrigate with greywater, so you should be able to as well if you’re using the right products and are directly the right amount of water to the plants.
