|I live in San Diego. My Hydrangea are green and healthy but continue to have browning on the edge of their leaves. What causes that and what can be done to prevent it?

|Sunscald, fertilizer burn, or overwatering can all cause crispy brown edges on the leaves. Don't feed your plants this season and water deeply only once each week. This will encourage deep root growth and counteract any problems related to turfgrass fertilizers (if your plants are growing near where a regularly fertilized turfgrass is growing). Hope this helps!
