Coming soon: Much cooler temperatures with possibility of rain

The last week of summer will feel like fall – and maybe get a little damp.
After a record-hot summer, this final week starts with a dramatic cooldown. Sunday (Sept. 15) is expected to top out around 77 degrees, 15 degrees cooler than Saturday’s forecast high, says the National Weather Service. Monday’s high won’t even reach 70.
The real surprise: A chance of showers on Monday and Wednesday. It’s no sure thing – 30 to 50% probability, says the weather service. Even if it does rain, it won’t be much (less than 0.1 inches in Sacramento). But it’s enough to break the heat and nudge us into fall planting season.
A little September rain is normal for Sacramento, which averages 0.29 inches of precipitation for this month. But we haven’t had any measurable rain in downtown Sacramento since May 4. These showers, if they develop, could rinse off a lot of dust.
By next weekend, temperatures (and weather conditions) will be back to normal for September in Sacramento: 85 degrees -- and sunny.
Make the most of this cool break – and get things done. Your garden needs you!
* Now is the time to plant for fall. The warm soil will get cool-season veggies off to a fast start.
* 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 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 and cauliflower as well as lettuce seedlings.
* 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 bulbs, rhizomes and perennials.
* Dig up and divide daylilies as they complete their bloom cycle.
* Divide and transplant peonies that have become overcrowded. Replant with "eyes" about an inch below the soil surface.
* Late September is ideal for sowing a new lawn or re-seeding bare spots.

Garden Checklist for week of Nov. 3
November still offers good weather for fall planting:
* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.
* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.
* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.
* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
* Prune non-flowering trees and shrubs while dormant.
* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
