| I have 2 hydrangea on my deck in 2 separate pots (the largest ones from Home Depot). It is partial sun because there is an awning. They are not lush and some leaves are turning brown- Endless Summer and a Forever and Ever Pinky. It was good soil with compost and they get diluted Miracle-Gro about every 7-10 days. |
| I'm stumped! Overwatering can cause browning leaf margins; a salt build up from fertilizer can do the same; wind burn can also show up as browning leaf margins. Sounds as though you are giving your hydrangeas good care but I wonder if you are overwatering? Allow the top of the soil to dry out between water applications. Even though the top of the soil feels dry to the touch the soil at the bottom of the container, where the roots are, can still be quite moist. Too much water can drive out oxygen and slowly kill the roots. Try watering as usual and then picking up the pots to see how heavy they are. Wait a few days and pick them up again. If they still feel heavy, there's still plenty of moisture in the soil and you won't need to water. If they feel lightweight, it means the soil is drying out and it's time to water. Hope this information is helpful. |
