June ends with another dangerous heat wave. According to the National Weather Service, an Excessive Heat Warning is in effect from Saturday afternoon through 10 p.m. Wednesday. For parts of the Valley and foothills, temperatures could peak at 111 degrees.

Ouch! That’s more than 20 degrees above normal for late June in Sacramento.

The heat will be most intense in the foothills and valley north of Sacramento. Closer to the rivers and downtown, high temperatures will be more tolerable, climbing to “only” about 100.

Little overnight cool down will start each day warmer. Lows will stay in the mid 60s through next weekend.

During these extra-hot days, there’s a high chance of heat stress or illness for people and animals. Keep pets indoors or give them shade. Make share they have access to fresh water.

NWS’s advice for people: “Drink extra water. Avoid outdoor strenuous activities 10 a.m. to 8 p.m. Plan to be in air conditioned buildings.”

That applies to gardening, too. Give vulnerable plants a drink in the morning. Take care of chores early in the day. Then, retreat indoors.

* Keep your vegetable garden watered, mulched and weeded. Water before 8 a.m. to reduce the chance of fungal infection and to conserve moisture.

* Erect temporary shade for plants that are getting too much sun. Watch peppers, eggplant and tomatoes for sunburn.

* Don’t let tomatoes wilt or dry out completely. Give tomatoes a deep watering two to three times a week.

* Harvest vegetables promptly to encourage plants to produce more. Squash especially tends to grow rapidly in hot weather. Keep an eye on zucchini.

* Pick up fallen fruit. It attracts pests.

* Pinch back chrysanthemums for bushy plants and more flowers in September.

* Harvest tomatoes, squash, peppers and eggplant. Prompt picking will help keep plants producing.

* Remove spent flowers from roses, daylilies and other bloomers as they finish flowering.

* Pinch off blooms from basil so the plant will grow more leaves.

* It's not too late to plant summer annuals such as petunias, snapdragons, zinnias and marigolds.

* From seed, plant corn, pumpkins, radishes, winter squash and sunflowers. Seeds may need daily watering to sprout.

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.
