December in the Garden
To all the lovely people,
A few more days and it will officially be winter. I'm sure, like me, you have been enjoying the rain and the life it is bringing from the soil. It is not too late to sow cover crop but last month would have been better. If sowing cover crop is not your thing then just spreading 2"-4” of mulch or a bale or two of straw (or better, alfalfa) over the garden and letting it remain in place until March will add humus and nutrients for the organisms in the soil to feed on and grow in number by the billions. By spring when you dig into your soil it will feel softer and easier to work and your seeds and plants will do much better. No matter if you grow or sheet your soil cover you will save water in the upcoming garden season.
Roses can begin being pruned starting next week (December 7 as one respected expert says). If you haven't already done so spring blooming bulbs can be planted - it is not too late.
Please write if you have any garden questions.
Happy gardening and happy holidays.
Paul
December To-Do List: Zone 9
- Apply lime-sulfur spray to peaches and nectarines to combat peach leaf curl.
- Apply a dormant oil spray to fruit trees to kill insects and eggs.
- Sow winter cover crops, including annual rye grass (Lolium multiflorum), fava beans (Vicia faba), oats, barley, pearl millet (Pennisetum americanum), or proso millet (Panicum miliaceum).
- At month's end, plant perennials, shrubs, and trees.
- Also at the end of the month, begin to prune established deciduous trees and shrubs to remove crossed and diseased branches and to open up the center to light and air.
December To-Do List: Zone 10
- At the beginning of this month, start cold-loving veggies, such as Brussels sprouts and English peas.
- Most citrus fruits ripen now—remove and compost old fruit or use for slug traps.
- Feed mangoes a shot of compost tea as soon as flower spikes appear.
- If rainfall is scarce, provide at least 1 inch of water per week.
- If frost threatens, be prepared to protect plants with row covers.
- Keep harvesting beans, beets, broccoli, carrots, greens, onions, potatoes, radishes, and melons.

Four Seasons in Solano County
Every September and early October I listen to my friend in Salem, MA rave about the fall color where she lives. I’ve seen it and I know what she means. It’s iconic autumn color and it’s spectacular. I’ve often heard out-of-staters pity us because we don’t enjoy a change of seasons that would bring us such glorious landscapes.
What my friends and most others who do not live here don’t understand, is that we do, in fact enjoy vivid fall color; it’s just later in the year. From the Bradford pear trees across the street from me to the Ginkgo down the block, to the spectacular red Chinese Pistache a few blocks away, my neighborhood is awash in fall color. It just happens that it’s December.
Rather than pity us for our lack of seasonal change, non-Northern Californians should marvel at the fact that we can experience all four seasons at the same time! Within a couple of miles of my house I can see trees arrayed in autumn finery, the rich, dark soil of plowed winter fields, beautiful spring grains and grasses sprouting in the valley and up the hill sides, and colorful flowers growing in home gardens.
Aren’t we lucky? Where else could we experience all four seasons in one place and at one time.
