Advice for the Home Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County
Help Desk Response: As I said in our conversation today, your insect is not a bed bug, but rather a mite of some kind. From its appearance, I believe it is a rat mite. There are also bird mites that can invade homes and bite people, but its appearance is closer to the rat mite.
These mites need rodents to survive, but will come into homes when their preferred hosts die or decrease in number. They cannot survive for too long without their hosts, even though they feed on humans. If there is a large population of rodents (rats or mice) in your attic or crawlspace, you might see a continued presence of these mites.
Here is a link to information from Contra Costa Vector Control District: https://www.contracostamosquito.com/mites.htm and from
Alameda County Vector Control about biting mites:

I didn't ask if you had rodent problems in your home, but I would be surprised if you did not (rat infestations are very common in our area). These links below are to information about controlling rats and mice: http://ipm.ucanr.edu/PMG/PESTNOTES/pn74106.html;
http://ipm.ucanr.edu/QT/housemousecard.html.
More information can also be found on the Vector Control districts.
I hope this information is helpful and you're able to get rid of these pesky biting creatures. Please let us know if you have more questions.

Help Desk Response: Thank you for contacting the UC Master Gardener Program Help Desk and for sending those good photos of the little white things on your soil. As I said in our conversation earlier today, they look like a type of slime mold and are not harmful to your garden. They eat bacteria and fungal spores, as well as organic debris and are not harmful to your garden They come in a wide variety of colors, shapes and sizes.
Slime molds are pretty interesting organisms. They start out as individual cells and join together into a moving, sometimes pulsating mass. I found a couple of articles and videos about slime molds you might find of interest:
From KQED Science: https://www.kqed.org/science/635319/this-pulsating-slime-mold-comes-in-peace

MGCC Help Desk's Response: Thank you for contacting the UC Master Gardener Program Help Desk with your questions. I know the list of available tomato seeds and seedlings can be overwhelming.
Unfortunately, given our area each area can have lots of micro-climates. So we cannot tell you exactly which variety will grow best in your yard. That is highly dependent on your individual circumstances (are you planting in pots, raised beds, the amount of sun, temperature, disease). Your best information on how individual varieties will perform is likely from your successful tomato-growing neighbors.
There is some good information about heirloom tomatoes though. The scientific definition of an heirloom tomato is an open-pollinated variety that will make fruit identical to the parent. This means if you save seeds from your tomatoes you would expect to be able to produce the same fruit year after year. There is disagreement on how old a variety has to be to be considered an heirloom with some saying at least 50 years and others saying at least 100 years. Here are some links to articles written by nearby Master Gardener organizations which discuss heirloom tomatoes in further detail. In addition, if you want to save seed yourself you might look over the website for Seed Savers Exchange.

If you look through our list of tomatoes for our Great Tomato Plant Sale this year, you can see there are lots of different heirloom tomato varieties. It does appear that only one is a determinate variety (Black Sea Man, a slicer). As you likely know, determinate tomato varieties grow in more of a bush form than a vine and tend to set fruit all at once and then decline. For older varieties, most are likely going to be indeterminate. If you look through the offerings on Seed Savers, only 9 out of their 82 heirloom varieties appear to be determinate. You likely have found these lists already but below are the links to our descriptions of all our varieties and the shopping list to make it easier to find what you want the day of the sale.

Advice for the Home Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County
MGCC Help Desk Response: Thank you for contacting the UC Master Gardener Program Help Desk with your question about the change in the appearance of your rose blossoms.
The most common reason for a change in the appearance of rose blossoms is root stock take over, and we suspect this may be the case with your rose. It is not unusual for the rootstock rose to send up suckers and even take over the preferred rose.
Many roses are grafted. This means that a bud from a preferred species is grafted to the rootstock of a different species usually known for its vigor and longevity. Any shoots that grow from stems above the graft union will produce flowers from the preferred species. But any shoot that grows from stems or below the graft union will produce flowers from the rootstock. The two will usually differ in flowers and foliage form and color. You can trace the canes from the rootstock to their point of origination and remove them; otherwise, they will eventually replace the preferred species.
Here are some helpful links to UC information on rose care:

http://ipm.ucanr.edu/PMG/PESTNOTES/pn7463.html
If rootstock takeover doesn't appear to be the cause of the change in your rose blossoms, please give us a call and let us know and we can discuss further.

Help Desk Response: Thank you for contacting the UC Master Gardener Program Help Desk.
You sent a photo of a plant for us to identify. It is rosemary (Rosmarinus officinalis). While it's not native to California (it originated in the Mediterranean area), it is very well adapted to California's similar Mediterranean climate. Its flowers range in color from various shades of blue to even pink and white. Its growth habit ranges from stiff and erect, rounded, or low and creeping, depending on variety or cultivar.
This plant is also the rosemary used for seasoning food, however some varieties taste better than others. Bees are attracted to the flowers and make excellent honey when feeding on them.
Good drainage and full sun are essential for a healthy rosemary plant. The links following will take you to more information about growing rosemary: http://ipm.ucanr.edu/PMG/GARDEN/PLANTS/rosemary.html and http://sonomamg.ucanr.edu/Plant_of_the_Month/Rosemary/.
