Sacramento Digs Gardening: Dig In: Garden checklist for week of July 26

Overnight cooldown balances out afternoon heat

We may not reach triple digits, but expect this week to have its share of heat. That's normal for the waning days of July, historically Sacramento's hottest week of the year.

Highs for this week average 95 degrees. According to the National Weather Service, we'll have hot, sunny days topping out at 98 degrees Sunday before settling down into a string of mid 90s -- in other words, average weather for midsummer in Sacramento.

Fortunately, our nights will dip down to 60 or even a little cooler. That keeps the mornings (and soil temperature) comfortable.

Get out early and enjoy your garden before the mercury starts climbing.

* Feed citrus trees their last round of fertilizer for the year. This will give a boost to the fruit that's now forming.

* Harvest tomatoes, beans, squash, pepper and eggplants to prompt plants to keep producing. Give your plants a deep watering twice a week, more if planted in containers. Also, give them a boost with phosphate-rich fertilizer to help fruiting. (Always water before feeding.)

*Watch out for caterpillars and hornworms in the vegetable garden. They can strip a plant bare in one day. Pick them off plants by hand in early morning or late afternoon.

* Mulch can be your garden's best friend -- it conserves moisture while blocking out weeds. But don't let mulch mound around stalks, stems or trunks. That can promote rot.

* Camellia leaves looking a little yellow? Feed them some chelated iron. That goes for azaleas and gardenias, too.

* Pinch off dead flowers from perennials and annuals to lengthen their summer bloom.

* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.

* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.

* In the garden, direct seed beets, carrots, leaf lettuce and turnips.

* Plant potatoes.

Garden Checklist for week of April 21

This week there’s plenty to keep gardeners busy. With no rain in the immediate forecast, remember to irrigate any new transplants.

* Weed, weed, weed! Get them before they flower and go to seed.

* April is the last chance to plant citrus trees such as dwarf orange, lemon and kumquat. These trees also look good in landscaping and provide fresh fruit in winter.

* Smell orange blossoms? Feed citrus trees with a low dose of balanced fertilizer (such as 10-10-10) during bloom to help set fruit. Keep an eye out for ants.

* Apply slow-release fertilizer to the lawn.

* Thoroughly clean debris from the bottom of outdoor ponds or fountains.

* Spring brings a flush of rapid growth, and that means your garden is really hungry. Feed shrubs and trees with a slow-release fertilizer. Or mulch with a 1-inch layer of compost.

* Azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.

* 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, 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.

* Mid to late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.

* Transplant lettuce seedlings. Choose varieties that mature quickly such as loose leaf.
