August ends on a warm note, but cooler days coming soon
Coneflowers come in more colors than just purple. Seed some now for bright flowers beloved by pollinators. Kathy Morrison
August ends of with more days in the upper 90s, nudging triple digits. But relief is on the way.
According to the National Weather Service, a cooldown is coming soon, maybe by Labor Day weekend.
This week, forecast highs for Sacramento call for comfortable mornings with temperatures in the 70s before warming to the high 90s in the afternoons. That peaks with an expected high of 100 on Wednesday.
However, by Friday (and the start of September), we’ll be back down in the 80s. Friday’s forecast high is only 86 degrees, five degrees below normal.
Plan accordingly; put off transplanting until next weekend. Take care of garden chores in the early morning including deep watering your vegetables.
* 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.
* Pick up after your 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.
* Prepare for a fall full of flowers by paying a little extra attention to your garden. Cut off spent blooms from roses, annuals and perennials, then give them a boost of fertilizer. Make sure to water plants before feeding. Roses will rebloom about six to eight weeks after deadheading.
* Divide and replant bulbs, rhizomes and perennials. Bearded iris should be at the top of that list.
* Dig up and divide daylilies as they complete their bloom cycle.
* Keep harvesting tomatoes, peppers, squash, melons and eggplant.
* Compost annuals and vegetable crops that have finished producing.
* Cultivate and add compost to the soil to replenish its nutrients for fall and winter vegetables and flowers.
* Fertilize fall-blooming perennials, too. Chrysanthemums can be fed until the buds start to open.
* 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.
* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.

Garden Checklist for week of Feb. 16
Take advantage of this nice weather. There’s plenty to do as your garden starts to switch into high gear for spring growth.
* This is the last chance to spray fruit trees before their buds open. Treat peach and nectarine trees with copper-based fungicide. Spray apricot trees at bud swell to prevent brown rot. Apply horticultural oil to control scale, mites and aphids on fruit trees.
* Check soil moisture before resuming irrigation. Most likely, your soil is still pretty damp.
* Feed spring-blooming shrubs and fall-planted perennials with slow-release fertilizer. Feed mature trees and shrubs after spring growth starts.
* Transplant or direct-seed several flowers, including snapdragon, candytuft, lilies, astilbe, larkspur, Shasta and painted daisies, stocks, bleeding heart and coral bells.
* In the vegetable garden, plant Jerusalem artichoke tubers, and strawberry and rhubarb roots.
* Transplant cabbage and its close cousins – broccoli, kale and cauliflower – as well as lettuce (both loose leaf and head).
* Indoors, start peppers, tomatoes and eggplant from seed.
* Plant artichokes, asparagus and horseradish from root divisions.
* Plant potatoes from tubers and onions from sets (small bulbs). The onions will sprout quickly and can be used as green onions in March.
* From seed, plant beets, chard, lettuce, mustard, peas, radishes and turnips.
* Annuals are showing up in nurseries, but wait until the weather warms up a bit before planting. Instead, set out flowering perennials such as columbine and delphinium.
* Plant summer-flowering bulbs including cannas, calla lilies and gladiolus.
