Gardening Tips

Yellow Jackets

Yellow jackets buzzing around pop cans, hamburgers and fruit salad can ruin barbecues. And, because their sting can be life-threatening for some people, it might be necessary to destroy nests found near human activity.

Be on the lookout for symptoms of tomato late blight
Late blight, a fungal disease that infects tomatoes, usually shows up in Oregon gardens as weather turns wet and humid, and it’s dispersed by the wind and rain.

Let annuals go to seed in the fall
Good seed setters include sweet peas, sunflowers, calendula, borage, nasturtiums and annual delphiniums.
Deadheading a rhododendron

Deadheading makes sense for repeat bloomers and highly modified annuals, but for most other plants it is a matter of appearance and the personal taste of the gardener.
Black-eyed Susans
Tips for saving water in the summer yard
