Dig In: Garden checklist for week of Nov. 20

Keep your sweater handy – and some warm gloves, too.

Sacramento can expect another clear and chilly week, according to the National Weather Service. Daytime highs will be mostly in the low 60s before finally warming up to 66 by Thanksgiving Day. Overnight lows will dip into the 30s, flirting with frost danger.

“Near freezing temperatures are expected for the Valley and foothills through the weekend into Monday morning,” tweeted the weather service’s Sacramento office. “Don’t forget to bring your pets indoors!”

Give animals a warm, safe place to sleep, off cold floors, says the weather service.

Take care of your plants, too. Insulate new transplants with a blanket of mulch. Keep frost cloths handy for the most sensitive plants such as succulents, tropical plants and young citrus trees.

By next weekend, overnight lows are expected to warm slightly, staying above 40 degrees. Although we’ll see some clouds by midweek, no rain is in the forecast.

Stay warm by enjoying some outdoor activity, like showing your garden some TLC.

* Cold nights and gusty winds are quickly finishing off autumn foliage. Rake up fallen leaves – great for making compost. Turn some of those leaves into mulch.

* 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 – when there’s no rain in the forecast and any wind has died down.

* 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.

* Now is still a great time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from 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.

* Give your azaleas, gardenias and camellias a boost with chelated iron.

* After they bloom, chrysanthemums should be trimmed to 6 to 8 inches above the ground. If in pots, keep the mums in their containers until next spring. Then, they can be planted in the ground, if desired, or repotted.

* Prune non-flowering trees and shrubs while dormant.
