Keep an eye on tomatoes as they ripen in hot weather

Make the most of comparatively mild temperatures this weekend as we continue to ride a weather rollercoaster.

According to the National Weather Service, Sacramento will see high temperatures on Saturday near 85 degrees – normal for mid-June – with overnight lows dipping down to the mid-50s.

By Sunday, the mercury starts zipping up again. Tuesday afternoon, we’ll be back to triple digits (or pretty close).

The forecast then calls for cooling into the low 90s by next weekend.

Thankfully, morning temperatures will be in the 60s and 70s throughout this stretch. Get out early and get things done!

You should see plenty of green tomatoes now.

* Expecting ripe tomatoes by the Fourth of July? Watch your tomatoes closely during these dramatic ups and downs in temperature. Windy conditions can dry out plants, too.

* Prevent problems such as blossom-end rot through steady irrigation. Keep your garden evenly moist (not soggy) through hot spells.

* Water early in the day to make the most of that moisture. Morning irrigation allows for more water to soak in, not evaporate. It also cuts down on fungal disease.

* Speaking of fungal disease, high heat will make several different fungal diseases disappear. That includes powdery mildew on roses. Remove infected leaves (including any that make have accumulated under bushes) and water deeply. The bush should grow out new healthy leaves.

* Trim off dead flowers from rose bushes to keep them blooming through the summer. Roses also benefit from deep watering and feeding now. A top dressing of aged compost will keep them happy. It feeds as well as keeps roots moist.

* Feed camellias, azaleas and other acid-loving plants on cooler mornings; always water deeply before fertilizing.

*Mulch to conserve moisture and reduce heat stress.

* Cut back Shasta daisies after flowering to encourage a second bloom in the fall.

* Pinch back chrysanthemums for bushier plants with many more flowers in September.

* Harvest fruit before the birds and critters get it. Pick up fallen fruit; it attracts pests.

* From seed, plant corn, pumpkins, radishes, squash, melons and sunflowers.

* Transplant summer annuals such as petunias, marigolds and zinnias.

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.
