Learn about planting leafy vegetables like lettuce and spinach, and root vegetables like carrots, beets and radishes. Not to mention broccoli and cauliflower. All of these vegetable plants can be grown in the ground or in containers. Great class for beginning gardeners.
We are excited to say that our classes are at nine Stanislaus County Library Branches! We hope to see you there.

Hello
We have been evaluating several herbicides on direct-seed Brassica vegetables: Bok choi, broccoli raab, collard greens, mizuna, mustard greens and radish. We also have evaluated several herbicides in transplanted Brussels Sprouts and Kale. Most of these crops appear to be quite tolerant of Dual Magnum.
The individual trial reports are attached.

2020.02 IR-4 collards & mizuna report 012121
2020.03 IR-4 mustard green & radish report 012121

Planting Cover Crops Enriches the Soil.
By T. Eric Nightingale
UC Master Gardeners of Napa County
The long summer of vegetable gardening can leave your soil in need of some rejuvenation, a perfect job for cover crops. Also known as “green manure,” cover crops are a natural and easy way to keep your garden soil healthy. They return nutrients to the soil, improve soil texture, prevent weeds and reduce erosion. The most effective and frequently used cover crop plants are legumes, grasses, grains and brassicas.
Returning nitrogen, a primary plant nutrient, to the soil is possibly the most important role of cover crops. Legumes are extremely good at this. They nurture Rhizobia, bacteria that converts nitrogen in the air into ammonia. Plants can later process this ammonium to obtain nitrogen from it. Rhizobia can't live in the soil on their own, however, so they use the roots of certain plants as a host. Some companies even sell seed with Rhizobia added to the mix. Legumes used as cover crops include fava beans, hairy vetch and clovers.
Brassicas such as radish and mustard are widely used as cover crops in vineyards. You have probably seen them flowering around Napa Valley. These plants grow deep (sometimes as deep as four feet), strong roots that break up the soil, letting water flow deeper into the ground.
Well-hydrated soil not only helps your plants, but allows for more soil organism activity. Grasses such as barley and ryegrass also help to break up the earth, but also allow for the introduction of high amounts of organic matter when they are turned back into the soil. It is common to use many different types of cover crops, in a mix, to provide as much benefit as possible to your garden.
Helping to retain moisture, improving soil texture and increasing fertility all contribute to a robust soil ecosystem. When this system of microbes, fungi, bacteria and other organisms is functioning as intended, the likelihood of soil-borne diseases greatly reduces. Even a garden needs to eat its greens to stay healthy.
Fall is a great time to plant cover crops, since many gardeners take a break between vegetable crops. You can sow cover crops directly from seed, broadcasting them by hand over the soil after tilling it lightly. Cover the seeds with a thin layer of soil to protect them while they germinate. You can add a small amount of fertilizer to give the young plants a jump-start on life. You will get a large return on this small investment when the plants grow.
Cover crops can also be used in the summer. Grasses such as sorghum, soybean and cowpea are often grown at this time. Also used are buckwheat and sunflower, giving the added boon of attractive flowers.
When the cover crops are at the end of their lives or you want to plant something else, turn them into the earth. Their organic matter will break down and further improve the soil. Alternatively, you can mow them and leave them on top of the soil as a mulch. They will eventually decay but in the meantime will further decrease water loss and erosion.
Cover crops also suppress weeds by blocking the sunlight, keeping weed seeds from germinating. If they are left on the soil surface as a mulch, they continue their weed-prevention duties. Some cover crop flowers feed bees, and fava beans, a popular cover crop, are edible and delicious.
There has been extensive research and testing on cover crops in recent decades. Their wonderful features make them sound like a cure-all for anything that ails your soil. In truth, they are one of many contributors to a healthy and productive garden. There is no doubt, however, that any garden will benefit from cover crops.
Workshop: U. C. Master Gardeners of Napa County will hold a workshop on the different kinds of poinsettias and other potted plants for holiday decorating using color and shapes. The workshop will be held on Thursday, December, from 7:00 p.m. to 8:00 p.m., at the Napa County Library, 580 Coombs Street, Napa. This is a free workshop and registration is not required.
Master Gardeners are volunteers who help the University of California reach the gardening public with home gardening information. U. C. Master Gardeners of Napa County (http://ucanr.edu/ucmgnapa/) are available to answer gardening questions in person or by phone, Monday, Wednesday and Friday, 9 a.m. to Noon, at the U. C. Cooperative Extension office, 1710 Soscol Avenue, Suite 4, Napa, 707-253-4143, or from outside City of Napa toll-free at 877-279-3065. Or e-mail your garden questions by following the guidelines on our web site. Click on Napa, then on Have Garden Questions? Find us on Facebook under UC Master Gardeners of Napa County.

Call me the Indiana Jones of gardening, but I wanted some adventure from my summer garden. I wanted to discover something “new” that was old (I hear that line from the movie ringing in my head, “It belongs in a museum!”). Among our adventures were the following:
The Heirloom Sweet Chocolate Pepper. This is a brown-skinned pepper at maturity, which starts out green, and is supposedly red fleshed on the inside (kind of like those glowing stones from the “Temple of Doom”). It is said to taste sweeter than the average bell pepper. Of course, it’ll add color to any salad and one review I read said it freezes well for winter use. You’ll see a picture of my plant below of a mature brown one and a “newbie” green one behind it.
The Psidium 'Lemon Yellow', or Lemon Guava was another adventure. Maybe you’ve heard of the Strawberry Guava Tree, well here is its cousin. Like Indiana in “The Last Crusade” looking for a golden statue, these yellow treasures make their trip from South America too. The little fruits are prolific on it, and I think we were just waiting for a bit more sun and warm weather to ripen them up so we’ll be able to reap our golden reward. We have it in a container and everything I’ve read says it’ll be fine there for quite a while.
Another veggie that I discovered was Black Spanish Radish. I found the seed packet hidden in a huge seed display at a local discount store. As you’ll see by the picture these didn’t get too big. The packet didn’t exactly “map out” any details, so I planted them like any other radish. As I’ve recently found out though, they are a winter variety and that could attribute to them not reaching their potential. They are definitely black though. That isn’t mud you’re seeing, that is the skin color! Well, the only “Jones” reference here is that apparently, they have been used medicinally by other cultures for thousands of years, and we all know Indiana was always eating or drinking some kind of concoction to cure something or protect him from something. I don’t know what they’d cure, but the ones that came from our garden sure have a “bite” to them! They start out with a regular radish flavor, and the heat builds from there.
So join me on an adventure in the garden this summer. It might be a little more relaxed than running from gigantic boulders or dodging poison-tipped arrows, but at least we get to wear cool hats!
