This is the time of year you might spot the beautiful, majestic dance of the honeybees
Most swarming activity takes place from April through May. Bees don't swarm during the rain, so this year we will most likely see the time frame pushed back a few weeks.
Honey bees, Apis mellifera, swarm for one of two reasons. Either the hive has become too crowded so they split into two groups (or more), with one group remaining in the existing hive. Or they abscond. In this case, all bees including the queen abandon the existing hive completely due to lack of food or water, parasite or disease infestation, frequent disturbance by humans or animals, weather changes, poor ventilation, or problems with the queen.
Western honey bees aren't nearly as likely to abscond as African honey bees, (a hybrid of South American and European bees known as Africanized honey bees), which tend to swarm more and be a bit more defensive as well.
Worker bees are able to detect when it's time to swarm due to overcrowding of the hive or the lack of pheromone production from the queen. In preparation for the swarm, the workers will deprive the queen of food in order to slim her down so she can fly. They will also agitate and run her around in order to prevent her from laying many eggs. If they are going to swarm, they will create new queen cells and allow the queen to lay eggs so a new queen can emerge and take over the hive.
Besides making honey, honey bees are essential for pollinating approximately 90 percent of our crops globally. Many of our favorite foods like almonds, most of our cherries, apples, blueberries, and other fruit and nut crops wouldn't exist without these hard-working bees.
According to Deb Conway with GirlzWurk in Saratoga, “Honey bees aren't usually a problem, as they normally set up their hives in tree cavities, shrubs, light poles, or abandoned buildings. However, they can become a nuisance when they take up residence in the walls of your home, garden shed or in your water meter.”
That's when it's time to call someone like Deb who can come and rescue the hive.
Last year was a particularly bad year for honey bees. Some beekeepers reported up to a 90 percent loss in their hives in 2018. Causes for this include varroa mite infestations, increased pathogens due to the warm weather, increased use of pesticides, and a decrease in diversity of food sources.
So, what can we do about a swarm? “If you leave the bees alone, they will leave you alone.,” said Dr. Elina L. Niño, a honey bee expert at UC Davis. “It only takes a few hours, or at most a day or two, for them to find and settle into their new home.”
Bees, as well as our other important and beneficial insects, are struggling. Our tendency to develop land and our extensive use of harmful chemicals are wiping out their natural habitat.
The public can truly make a difference by ceasing to use pesticides and by planting an array of beautiful, attractant plants such as ceanothus, lavender, echium, rosemary, penstemon and mint (mint is only recommended in containers because it is so invasive). For more bee-friendly plant ideas, visit UC Davis Häagen-Dazs Honey Bee Haven.
Let's all commit to creating safe and nurturing spaces in our backyards, gardens (and yes, even on those balconies and decks) where our much-needed pollinators and beneficial insects can not only survive, but thrive!

I planted it in a spot on the side of our home near the driveway where I had had a hard time getting anything to grow and really take off.
Let me tell you, I hit passion-pay-dirt with this little one-gallon plant! Not only has it taken off, it is trying to take over the side of my small, built-in porch.
Passiflora, or passion flower, is a genus of more than 500 species of flowering plants. Most are vines that have prolific tendrils for climbing, but some grow as hearty shrubs or even trees. Ninety-five percent of Passiflora edulis, or passion fruit, (often known as granadillas) come from South America. The rest come from Asia, Australia, and North America. They are edible, vining varieties that are coveted for their fruit as well as their juice. Fruit can either be purple, yellow or bright green and can range in size from as small as a pea to as large as a grapefruit.
They are sensitive to severe frost and prefer a moderately cool area when planted in warm climates. They like a relatively humid, moist area – but not too wet. If you decide to plant one, be sure to provide enough irrigation throughout the warmer months, but cut back on the water when the cooler weather hits.
Be sure to amend with organic compost, agriculture lime and bone meal. When I planted mine, I mixed in organic soil amendment, some compost and a little bit of slow-release organic fertilizer (as I do with most everything I plant).
Passionfruit are really beautiful plants with dark green foliage and unusual, striking flowers that look like little fringy-starbursts. Flowers can range from vibrant red and brilliant fuchsia to blue, pink, all shades of purple and even tricolored.
Although my plant had no tag, I believe it is the common purple granadilla because of its creamy white petals, deep purple crown and lime green ovary, anthers, and stigma.
It has been in the ground for six to eight months, and I am so impressed with how easy it has been to grow. I am trying to train it into an espalier form. I just trimmed away about half of the plant and made four horizontal branches across the length of my porch (see photo).
I have already harvested a couple of fruits and they are quite tasty.
Even though flowers only last for a day or two and plants only survive three to six years – I would highly recommend trying one out. If you have the patience, you can try to grow it from seed, but if you're are like me just pick up a transplant from your local nursery or farmer's market and give it a grow!
You can sometimes find fresh passion fruit and juice in your local market. It is also becoming a popular ingredient in drinks, cakes, icing, ice cream, and yogurt.

Growing plants in the off-season is easy, productive and beneficial to our native birds, bees and bugs
If you aren't planning to plant an edible garden this fall, at least plant some cover crops wherever you normally grow your summer garden – even in your raised beds. Cover crops are excellent for “fixing soil”. They not only provide needed nitrogen, they also help loosen soil, suppress weeds, and support native birds and bugs with their flowers and seeds.
Fava beans are one of my favorite cover crops, but they will grow for several months.
If you want to grow a quick cover and still have time for your cool-season garden, try buckwheat. It will germinate in about five days and be ready to turn under in about a month.
To get all the education and plants you need, don't miss the upcoming Fall Garden Market at Martial Cottle Park's Harvest Festival on October 6.
Celebrating the agricultural heritage of Santa Clara Valley and the newest park in the county, the festival will feature food, entertainment, park tours and more. Master Gardeners will host children's activities, a Green Elephant sale, and a Help Desk LIVE! where you can ask questions and bring in a plant or pest sample to have it diagnosed.
There will be educational talks all day long including “Growing Great Garlic”, “Growing Cool-Season Crops” and “Designing with Succulents”. You can also visit the Habitat, Pollinator and California Native gardens that are on-site.
If you haven't tried growing Asian greens, you are missing out. They are easy to grow, very productive and can be used in salads, stir-fries, and soups. There will Chinese broccoli, pak choi, and tatsoi at the market.
How about some Italian greens such as chicory, escarole, frisee, radicchio, and rapini? There will also be dozens of varieties of beets, broccoli, cabbage and cauliflower, chard and kale. And, if salad is your thing, you will have a dozen varieties of lettuce to choose from – or like me, you can plant them all and have your own salad bar! There will also be peas, turnips, onions and even kohlrabi, collards, rutabaga, turnips, and artichokes.
Also, don't miss out on the flowering beauties: Agrostemma, Clarkia, Linaria, Snapdragons and Sweet Peas. Flowers not only add beauty, but they also bring in the bees and beneficial insects that are necessary for pollination and fending off the “bad bugs” that can damage your garden.
Growing your own food, whether with your family or just on your own, is not only enjoyable, it is truly important! You will conserve water, waste less (no one wants to throw away what they have worked hard to grow), avoid using harmful chemicals, nurture your soil and help support and feed our native birds, bees and bugs. And most importantly, you will make a huge and positive impact on your children – kids will actually eat what they grow! So, head on out to one of our upcoming Fall Markets and dig in!
Here are the details for the three upcoming Santa Clara County Master Gardeners Fall markets. The main event is the one at Martial Cottle Park on October 6. Entrance is free, but there is a $6 fee to park.
