Dig In: Garden checklist for week of Dec. 10

Clear skies have returned over Sacramento and so has the threat of frost.

According to the National Weather Service, “patchy frost” or “areas of frost” is in the forecast every morning Saturday through at least Thursday, with overnight lows dipping into the mid to low 30s. Most mornings, there will be just enough wind to make it feel like freezing – 32 degrees.

Daytime highs will actually be on the “warm” side – 60 to 62 degrees Monday through Friday. Average for this week in December: 54 degrees.

That chill will bring down many remaining fall leaves. Take advantage of these dry but crisp conditions. It’s time to get out the rake!

* Rake leaves away from storm drains and keep gutters clear.

* Fallen leaves can be used for mulch and compost. Chop up large leaves with a couple of passes with a lawn mower.

* Prune non-flowering trees and shrubs while they’re dormant. Without their foliage, trees are easier to prune.

* Rake and remove dead leaves and stems from dormant perennials.

* Make sure to take frost precautions with new transplants and sensitive plants. Mulch, water and cover tender plants in the late afternoon to retain warmth.

* Succulent plants are at particular risk if temperatures drop below freezing. Don’t water succulents before frost; cover instead. Use cloth sheets, not plastic. Make sure to remove coverings during the day.

* Clean and sharpen garden tools before storing for the winter.

* Brighten the holidays with winter bloomers such as poinsettias, amaryllis, calendulas, Iceland poppies, pansies and primroses.

* Keep poinsettias in a sunny, warm location. Water thoroughly. After the holidays, feed your plants monthly so they'll bloom again next December.

* Just because it rained doesn't mean every plant got watered. Give a drink to plants that the rain didn't reach, such as under eaves or under evergreen trees. Also, well-watered plants hold up better to frost than thirsty plants.

* Plant garlic (December's the last chance -- the ground is getting cold!) and onions for harvest in summer.

* Bare-root season begins. Plant bare-root berries, kiwifruit, grapes, artichokes, horseradish and rhubarb. Beware of soggy soil. It can rot bare-root plants.
