Spring’s last Open Garden is Saturday at Fair Oaks Horticulture Center

Get out early in the morning to take care of garden chores. Temperatures are expected to stay below 80 degrees before 10 a.m.

* Remember to water early and deep; your garden depends on you.

* 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.

* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.

* Water before fertilizing vegetables and blooming annuals, perennials and shrubs to give them a boost. Feeding flowering plants every other week will extend their bloom.

* Feed vegetable plants bone meal or other fertilizers high in phosphate to stimulate more blooms and fruiting.

* 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.

* If your melons and squash aren’t setting fruit, give the bees a hand. With a small, soft paintbrush, gather some pollen from male flowers, then brush it inside the female flowers, which have a tiny swelling at the base of their petals. (That's the embryo melon or squash.) Within days, that little swelling should start growing.

* 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.
