I too am paying much closer attention to the honey bees since hearing about the loss of so many hives. Last year I had the small blossom sunflowers in amongst my vegetables like squash and beans and the honey bees were going crazy for the pollen all summer. Of course they visited the other vegetable blossoms while they were at it. So far itÂs mostly native bees of all sizes. There is a large family of hunting wasps looking for insects including geranium bud worms. When my lemon tree was in bloom earlier this spring there were just a few honey bees visiting. It will be interesting to see what happens this year when the sunflowers bloom. I gage the health of my garden by how many critters want to live there. IÂve got snakes, lizards, toads, peepers, a few praying mantises during summer and a large variety of insects including those pesky leaf miners on my chard that I canÂt seem to get the upper hand on, in an organic way.

A friend of mine who created a deer "hedgerow" to try and keep them in the ravine rather in her garden, considered mock orange one of those the deer would browse but not kill, and that once it was established at least, was able to withstand their affections for it. Perhaps create a cage for it from chicken wire or something, so that at least initially, it has space to grow, and the deer can only nip the outlyers? For what its worth, it tends to like similar conditions to your Ceanothus- sunny edge to open areas, preferably on the dry side once established. Happy with summer irrigation, but once going strong shouldn't need it. In shade the plant will grow well, but not necessarily flower too well. On cascara as a moist forest species, I beg to differ. It is one of several trees folks taking care of the Mima Mounds, Glacial Heritage and similar prairies in the south sound area are weeding off the mounds and out of the meadows. It can and will take dry conditions very well. However, it does tend to change how it looks in dryer soils- smaller leaves, more compact habit. Osoberry will do the same, though it is much more dependent on moist spring soil than the cascara. Cascara does NOT like wet feet either. It will do ok along the edges of marshy areas, but rarely seeds itself into saturated soils. Of course, in the garden it will typically get more moisture than it tends to in the woods anyway. As far as Anna's not being native, well neither is the honey bee, lol. At least the Anna's is an American Native. Honeybees are old world bugs, however treasured by many. Both enjoy a winter nectar source.

I am by no means a master gardener nor am I very experienced in keeping bees. When I was a teenager, I kept honey bees because my grandfather was a beekeeper and told me that honey bees were the best pollinators around. However, my research on the internet and my discussions with other gardeners has shown me Grandpa was wrong. I grow lots of fruit. Recently, I started a small orchard to my yard. I have persimmons, apricot, Asian pears, plums, jujubes, peaches, cherries, paw paws, raspberries, figs, blackberries, blue berries, honeyberries, goji berries, strawberries, pomagranites, and kiwis. My vegetable garden includes eggplants, melons, tomatoes, potatoes, peppers, squash, and pole beans and all need bees. So you can see I have an interest in pollinating all of the above, otherwise my garden would be adversely affected. Since honey bees are a social bee, they communicate with each other about where to find the sources of pollen, nectar and water. Therefore the first blooms to open get the first attention. If you watch closely, the bees will exit from the hive and go straight to the blooms that opened first during the season. Bees become fixated, when a nectar source opens, the bees concentrate on that source, becoming fixed on that and little else until the bloom period for that plant is over. If your blossoms open a few days after your neighbor’s blossoms, by the time your neighbor’s blossoms have finished, your blossoms are half over, and old blossoms do not pollinate well, if at all. A bee that flies in cool, damp and cloudy weather, which honey bees don't, is also needed. It is also important that the maintenance of the bees doesn't require a great deal of time, which most gardners do not have. Since the blooming period is often short, the bees need to be able to work quickly and not get fixated on one nectar source. Mason bees are the ideal solution. Mason Bees only fly approximately 300 yards from its nest site, thus helping to ensure pollination of your blossoms, not your neighbor’s. Mason Bees (MB) are solitary and there are numerous strains. They do not need a nest site with thousands of worker support. While they do prefer others of the same strain around, mainly for mating purposes, the females do most of the work in provisioning the nest tube. The males are good pollinators in their own right, but their forage is for their own use, and not for their offspring. MBs nest in tubes, under natural conditions, mainly those left by burrowing insects. With the removal of mature trees there has been serious habitat loss, so MBs are in short supply and nest sites should be encouraged. These nest sites can be simple blocks of wood up to 6 inches deep, holes drilled approximately 5/16ths inch in diameter. The females will first close off the back of the nest tube with mud on the bottom plug she will use pollen as the feed plus a small amount of nectar, and lay an egg. This section is then sealed with a mud plug, then immediately she will start on a second nursery cell and so on till she gets towards the front of the tube at which time she will lay unfertilized eggs, creating males. Under good conditions MB females will lay at least 3 females and 2 males per tube, after which she will seal the end and move to a second nesting tube. Unlike honey bees, MBs carry the pollen in a sac beneath the abdomen. When a female lands on a flower she dives in belly first, right in the middle of the blossom stamens. Whereas a honey bee lands on the side and walks down looking for the nectar site, possibly brushing past the stamen in passing. Each blossom needs up to eight visits to effectively pollinate them. MBs will do a better job, purely because of their approach to each blossom. It should be obvious that MBs main interest is pollen whereas honey bees interest is nectar for honey making. So with honey bees pollen transfer is accidental, but with MBs, transfer is deliberate. As the honey bee carries the pollen in baskets on the back legs, brushed there when the bee cleans itself, so transfer is accidental. The MB is a hard worker, visiting hundreds of flowers to charge each egg site with pollen and the increase in fruit crops using them is well documented, in some cases up to a 4 fold increase. Unlike honey bees, they will start earlier in the morning, finish flying later in the day and cool damp weather doesn't prevent them working. In a few short weeks, the nest tubes are sealed and the larvae then eat through their stores, pupate, then wait in the tubes till next spring before emerging. The outer eggs turn into males, which emerge a few days before the females, then hang around waiting to mate with the emerging females. Caring for MBs cannot in any way be considered labor intensive. They work without supervision, sealing off their young from predation with mud plugs. Some provision should be made to stop wood peckers accessing the nest site and then late in the fall the nest site should be taken in, opened and the cocoons cleaned to prevent infestation by pollen mites. This is a learning experience and ideally a search on the internet for Mason bees or Blue Orchard bees will supply sites where more information is available and where bees can be purchased. I personally decided not to purchase MBs, but to construct bee boxes to attract the native ones. I have two nest boxes so far and one is populated from last spring. Another is located very close to the old one and is ready to accommodate MBs this spring. My intention is to cover the populated box with a cardboard box, with ½ inch holes in it, on or about March 15 to allow the MBs to exit but to discourage them from using the old box during this spring and encourage them to use the new box. Next, I will remove the old box around May 15 and clean it to kill mites and put it up again the next spring.

I am new to this also, but that sounds like a good location.mason bees i put mine on a fence post in my garden where i wanted them to pollinate; the house i used had an overhang. I mail ordered the mason bees, and taped the container of bees to the underside of the roof, and let them out. i did see a couple of the tubes filled with material, i dont know if that is the mason bees or another critter.
