Answer: Browning leaf margins are a classic symptom of droughty conditions. It's important that your elaeagnus recieves regular deep watering. One inch per week is usually sufficient, even in the wintertime. If your plant is near a foundation or under the eaves, be sure to water in the winter. Otherwise, natural rainfall should keep it happy all winter long. You can remove the affected leaves, which should signal your plant to produce healthy new leaves.
Best wishes with your landscape!
