Dandelions may be the easiest weed to identify,
if not always to eradicate. Other weeds are trickier.

Weeds are sneaky, often resembling plants we may want in the garden. This month's free webinar from the UC Integrated Pest Management Program is designed to help gardeners identify and control weeds in gardens and landscapes.
"Weed Identification" will be presented at 1 p.m. Thursday, Aug. 19. John Roncoroni, weed science farm adviser emeritus, is the instructor for this session. Webinars run for one hour. The series is free and open to the public but advance registration is required. Register here.
The next webinar, "Identifying Insect Pests in the Home and Garden," will be presented 1 p.m. Sept. 16, presented by Elaine Lander of the UC Statewide IPM Program. Registration for that webinar is here .

Garden Checklist for week of July 21
Your garden needs you!
* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.
* Feed vegetable plants bone meal, rock phosphate or other fertilizers high in phosphate to stimulate more blooms and fruiting. (But wait until daily high temperatures drop out of the 100s.)
* Don’t let tomatoes wilt or dry out completely. Give tomatoes a deep watering two to three times a week.
* Harvest vegetables promptly to encourage plants to produce more. Squash especially tends to grow rapidly in hot weather. Keep an eye on zucchini.
* Pinch back chrysanthemums for bushy plants and more flowers in September.
* Remove spent flowers from roses, daylilies and other bloomers as they finish flowering.
* Pinch off blooms from basil so the plant will grow more leaves.
* Cut back lavender after flowering to promote a second bloom.
* It's not too late to add a splash of color. Plant petunias, snapdragons, zinnias and marigolds.
* From seed, plant corn, pumpkins, radishes, winter squash and sunflowers.
