July really was hot; expect a normal August

It wasn't your imagination. If you thought this summer felt hotter than usual, you're right!

According to the National Weather Service, Sacramento daily highs in July averaged 96.9 degrees, 3.6 degrees above normal. We endured 10 days in triple digits, topped by two days (July 11 and 12) at 106.

We weren't the only folks who saw baking-hot temperatures. Redding, for example, had 21 triple-digit days in July, including 111 on July 15. Redding highs averaged 101 degrees for the month.

Fortunately, Sacramento overnight lows stayed normal -- 61 degrees. That nightly cooldown kept mornings (and soil) comfortable.

As for the week ahead? After a few more hot days, our afternoons will settle down into the low 90s with overnights dipping down into the 50s. That's normal; our August highs average 91 degrees with lows of 58.

Don't expect any rain soon. Our August precipitation averages 0.05 inches.

What to do during cool mornings this week:

* Harvest tomatoes, beans, squash, peppers and eggplants to prompt plants to keep producing.

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

* Pick up after your other fruit trees. Clean up debris and dropped fruit; this cuts down on insects and prevents the spread of brown rot. Then feed fruit trees with slow-release fertilizer for better production for next year.

* If camellia leaves are looking a little yellow, give them some chelated iron. That goes for azaleas and gardenias, too.

* Fertilize fall-blooming perennials, too. Chrysanthemums can be fed until the buds start to open.

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

Keep roses deadheaded.

* Trim off spent rose blooms.

* 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 27

Once the clouds clear, get to work. Spring growth is in high gear.

* Set out tomato, pepper and eggplant transplants.

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

* Transplant lettuce and cabbage seedlings.

* Weed, weed, weed! Don’t let unwanted plants 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.

* 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.

* Start thinning fruit that's formed on apple and stone fruit trees -- you'll get larger fruit at harvest (and avoid limb breakage) if some is thinned now. The UC recommendation is to thin fruit when it is about 3/4 of an inch in diameter. Peaches and nectarines should be thinned to about 6 inches apart; smaller fruit such as plums and pluots can be about 4 inches apart. Apricots can be left at 3 inches apart. Apples and pears should be thinned to one fruit per cluster of flowers, 6 to 8 inches apart.

* 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.
