Thanks to our mild winter weather, home gardeners on the central coast can grow vegetables year-round – lading their holiday tables with homegrown kale, carrots, snow peas and broccoli.
But before you hit the couch, take a fall afternoon to prepare your garden beds to make the most of our rainy winter season. A green cover crop or a straw-covered layer of manure will work slowly over the winter to enrich your soil, attract earthworms, and feed the legions of beneficial microbes needed for healthy spring crops.
Both techniques have their pros and cons.
Cover crops such as fava beans, vetch and mustard thrive in our winter weather, the beans and vetch teaming up with soil bacteria to pull nitrogen from the air and into the soil. The pros of cover crops include their beauty and variety. Mustard and vetch are spectacular in full bloom, and fava beans grow impressively tall and vibrantly green. Fava beans can also be harvested and eaten.
But cover crop seeds may require watering, at least until winter rains are constant enough to keep the soil evenly moist. And care must be taken to prevent weeds from infesting your cover crop. It's best to plant cover crops before the end of November, and to till them into the soil while they are still green and tender. UCSC's Center for Agroecology and Sustainable Food Systems has a great reference for cover crops here.
Layering manure and straw onto your planting beds, on the other hand, is a one-and-done deal. Simply pile on 2 or more inches of herbivore-generated manure – horse, cow, goat, llama or bunny leavings are all equally good – and tuck it up with a fluffy layer of straw or dry leaves three times as deep as the manure layer. The straw stays neat-looking for months, and thick layers of organic material will smother most weeds.
Winter rains keep the pile moist, attracting earthworms and helpful decomposers. Straw and leaves hold in moisture and prevent rain from compacting the soil. In spring, turn the composted manure and straw into the top layer of soil before planting.
The cons of this method include sourcing, transporting and shoveling animal poop, and waiting a couple of days for the barnyard aroma to dissipate.
Whichever method you choose, the result will be richer springtime soil with better tilth. And, possibly, a well-rested and ready-to-go gardener.

Happy New Year from the UC Master Gardeners of Monterey and Santa Cruz Counties!
So where does that leave our gardens and landscapes? Dry, dry, dry.
Evergreen plants are often the hardest hit by La Niña because they continue to use water for photosynthesis. Deciduous trees and shrubs require less moisture, but will benefit from some irrigation during periods of little to no rain. Remember, infrequent deep irrigation is better than frequent shallow irrigation. Don't forget to water your container plants as well.
Warmer temperatures sometimes cause shrubs to start putting out leaves early and while there's not much to do about that, be on guard for cold snaps that will freeze tender new growth. Before a freeze, water your plants, as soil moisture and hydrated roots will improve their cold hardiness.
In summary, La Niña has put us back in drought conditions. Unfortunately, we've had a lot of experience with drought here in central California.
For La Niña forecast information, visit the National Weather Service's Climate Prediction Center. For reminders on gardening in a drought, visit the UC California Garden Web.

"But he who dares not grasp the thorn Should never crave the rose."
-- Anne Bronte
Would a rose by any other name smell as sweet? Well, duh! It would still be a rose, even if it was called a nwliduwldkg! But ‘rose' is much easier to say, so we're lucky that way. If you've been dreaming of roses but haven't yet gotten up the nerve to give them a try, this post and our FREE Class on Jan 13th are for you. Sources for more detailed information are found at the end of the post.
- Hybrid tea roses
- most common roses in home gardens today
- form a shrub 3-5' tall
- large, single flowers
- Floribundas
- form a shrub 2-4' tall
- small flowers borne in clusters
- higher bloom production than hybrid teas
- Grandifloras
- intermediate between hybrid teas and floribundas
- large flowers with increased bloom production
- form a shrub 5-8' tall
- climbers
- flexible stems to 20' long
- need support on a wall, fence, etc.
- possess glossy green leaves
- have few thorns
- require little pruning
- require little disease and pest control
- well suited for low maintenance landscapes
- do not require deadheading
- flower throughout the year with greatest bloom in mid-spring and early autumn
Rose cultivation involves multiple factors, many of which are influenced by microclimate. In general, roses require:
- protection from wind
- lots of sun (full sun all day near coast, afternoon shade in hot inland areas)
- space with good air movement to prevent diseases
- well draining soil that still retains water
- light fertilization before each flush of growth
- watering by flooding basin around the plant with 1-2” water or using drip irrigation when the soil is dry to 1”
- avoidance of frequent wetting of leaves to reduce diseases
- when washing leaves to dislodge pests such as spider mites and aphids, do it in the morning so leaves are dry by nightfall
If you'd like to learn basics of rose care, be sure to sign up for our FREE class "The Basics of Rose Care" on January 13th at 10am here! Information in this post was taken from this Garden Information Series flyer. The UC IPM website has lots of information about pests and disorders of roses here and information about cultural practices and pest control here. For information on abiotic disorders and diseases, go here. And for information on rose insect and mite pests and beneficials, visit this page.
