Sacramento Digs Gardening: Dig In: Garden checklist for week of July 12

Are you feeling as fried as these roses? We are, too. And these need to be deadheaded.

Normal nights help gardens cope with heat

Hot days, comfortable nights; that's our weather pattern for mid-July.

According to the National Weather Service, Sacramento will continue to hit triple digits at least through Tuesday before settling back down into the low to mid 90s.

Fortunately, our overnight temperatures will keep dipping down to about 62 degrees -- normal for July. So, while days may reach 10 degrees above our mid-July average high of 92, those normal nights will refresh plants -- and us.

Those cooler nights also help keep soil and roots comfortable, too.

Until cooler days, concentrate on that comfort factor:

That's one droopy cosmos. Plants protect themselves in heat by
drooping, but keep them well-watered and they'll snap

back overnight.

* Keep plants hydrated but not soggy. Too much water can harm plants, too; check your moisture levels.
* Water early, preferably before 8 a.m., to cut down on moisture loss.
* Deep water trees, shrubs and perennials. Let the moisture soak in.
* Refresh your mulch. Cover bare spots. Don't let it pile up around trunks or main stems.
* Pick up fallen fruit; it attracts pests and problems.
* Pinch back chrysanthemums for bushy plants and more flowers in September.
* Harvest tomatoes, squash, peppers and eggplant. Prompt picking will help keep plants producing.
* Remove spent flowers from roses, daylilies and other bloomers.
* Pinch off blooms from basil so the plant will grow more leaves.
* Cut back lavender after flowering to promote a second bloom.
* From seed, plant corn, pumpkins, radishes, winter squash and sunflowers. Make sure seeds stay evenly moist.

Garden Checklist for week of May 5

Survey your garden after the May 4 rainstorm. Heavy rain and gusty winds can break the neck of large flowers such as roses. Also:

* Keep an eye on new transplants or seedlings; they could take a pounding from the rain.

* Watch out for powdery mildew. Warmth following moist conditions can cause this fungal disease to “bloom,” too. If you see a leaf that looks like it’s dusted with powdered sugar, snip it off.

* After the storm, start setting out tomato transplants, but wait on the peppers and eggplants (they want warmer nights). Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.

* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.

* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.

* Mulch around plants to conserve moisture and control weeds.

* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, pumpkins, radishes and squash.

* Plant onion sets.

* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias. Transplant petunias, zinnias, geraniums and other summer bloomers.

* Plant perennials and dahlia tubers for summer bloom.

* Don’t wait; plant summer bulbs, such as gladiolus and tuberous begonias.

* Harvest cabbage, lettuce, peas and green onions.
