September brings cooldown and another planting season

Relief is on its way! August ends with another smoky triple-digit weekend. But September starts Wednesday with some much needed coolness and (we hope) cleaner air.

According to the National Weather Service, Sacramento will smolder through Sunday with a forecast high of 101. Then, light winds will start to blow away the haze and bring high temperatures down. By Wednesday, we’ll be back in the mid 80s for the rest of the week.

Weather then will be ideal for setting out cool-season vegetables: Not too hot in the afternoon, but still warm and cozy after dark.

Wait this weekend, then get started in earnest on your fall and winter vegetable garden. Although there’s plenty to keep busy, avoid outdoor activity during poor air quality.

* Keep harvesting tomatoes, peppers, squash, melons and eggplant.

* Pull plants that have finished producing and compost.

* Cultivate and add compost or other amendments to the soil to replenish its nutrients for the next season of vegetables and flowers.

* Fertilize deciduous fruit trees.

* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.

* Transplant cabbage, broccoli, kale, Brussels sprouts, cauliflower, lettuce and other greens.

* Sow seeds of California poppies, clarkia and African daisies.

* Transplant cool-weather annuals such as pansies, violas, fairy primroses, calendulas, stocks and snapdragons.

* Divide and replant bearded iris as well as other rhizomes, bulbs and perennials.

* Dig up and divide daylilies as they complete their bloom cycle.

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.
