Mason Bees - The Friendly Pollinators

Mason Bees appear like a big house fly with a greenish black shine to them.

(Guest writer: Linda Zielinski) Did you know that Mason Bees (Osmia lignaria) are one of the most common hole-nesting bees? They are wonderful pollinators, especially for apples and pears. Researchers claim they can be up to 90% more efficient at pollinating than honeybees due to the fact that Mason Bees will forage in light rain and at cooler temperatures than honeybees and other pollinators. If you are worried or concerned about getting stung then this hard working little Mason Bee may be just what you and your flowers and vegetable gardens are looking for. Mason Bees are not aggressive since they are a solitary bee and are not defending a queen. They are considered quite docile. 

Linda's nesting boxes are hung under the eves, on the southeast side of a shed so they get sun and are protected from prevailing winds/rains. Insets show other styles of nesting boxes.

Nesting boxes for Mason Bees:  I have quite a few nesting boxes. My nesting boxes are hanging under the eaves of my pump house facing towards the southeast so they can be warmed by the early morning sun and protected from direct rain.  Mason bees are easy to care for. You can make new nesting boxes by using a drill press and a 5/16 bit and blocks of UNTREATED wood. You may also purchase nesting straws. I have found the straws at the WildBirdsUnlimited store in Corvallis. For right now I have placed 2 new nesting boxes and a package of straws for the ladies to use as new homes for their eggs. As these begin to fill up I will continue making new boxes. Last year the girls were so prolific that I had to make several new nest blocks 3 different times.

Mason Bee life cycle: This year, my Mason Bees began emerging in early April. The males hatch out first once our temperatures get above 55 degrees for 3 days in a row. The females seem to understand that it is important to lay female eggs at the back of the holes and lay the male egg at the front of each hole. This assures the survival of this species as it only takes one male to mate with several female Mason Bees. Once the weather begins to warm and the males emerge they then wait around for several days for the females to chew through their cocoon and then chew through the mud wall that divides each egg cell until they reach the end of the nesting hole and crawl out to live their short productive life in our wonderful Willamette Valley. The males then fly around chasing the females in a mating dance.

 

Once the males have mated their job is complete and they die. The females immediately begin gathering pollen and laying eggs. They do not excavate holes but look around their environment for a 4-6 inch-long space that is approximately 5/16 of an inch in diameter. They are often seen crawling up under house shingles. No need to worry though. They do not damage your siding but are merely looking for a safe, dry place to lay their eggs. After she has gathered pollen she will return to the nesting tubes/boxes, fly into the holes and turn circles inside which helps the gathered pollen fall off her body as she wiggles her way to the end of the tube.

There she will lay her tiny egg and put a pollen ball on top of that. She will leave about a 1 inch space and she then make a 1/4 inch mud plug to wall off that egg, hence the name "Mason" Bee. For the next 8-10 weeks these busy ladies continue gathering pollen and nectar. Sometime towards the end of June their life's work is over and they die. During the summer months the eggs develop into larvae. The larvae feeds on the pollen and nectar and develop into pupae. The Mason Bee pupae develop into bees protected inside a cocoon. They hibernate over the winter and emerge sometime towards the end of March or early April to start this marvelous life cycle over again.

Winter at the Sharing Gardens

Though the Sharing Gardens doesn't typically get a lot of snow, we did get about 5" in late December 2021. Here are our bird feeders overlooking our fruit and nut orchards to the south of our farmhouse.

Greetings dear friends, the worst of winter is probably over for us here in the Willamette Valley of Oregon (Zone 7b). Chris and I have had a restful time since the hubbub of fall harvests, seed and food preservation and garden-clean-up are behind us. Here is a photo essay showing how our winters are spent in preparation for spring's promise in the new year.

Late fall: Sandra sifts the compost that the worms produce in our paths while Chris harvests it. To learn more about creating soil-fertility using local materials, CLICK HERE.

Winter is the time when we begin adding wood-ash and coffee-grounds to our greenhouse beds and paths. The wood-ash is from our wood-stove (our only source of heat). Coffee grounds are a 'waste product' that our friend John Kinsey collects weekly from a coffee-shop. Worms love them! LINK-Coffee grounds and Wood-ash for fertility

Spreading coffee.

Spreading ashes.

Donn and Chris loosen the soil in our greenhouse raised-beds and dig in the ashes, coffee-grounds and worm-compost so beds are ready for spring planting.

It's early February and we already have planted carrots, beets, spinach and lettuce directly in our greenhouse beds. This picture is from 2021 but shows how we dig up onions that have over-wintered and replant them for green-onions we'll eat in early spring.

Now is the time to re-plant bulb/root crops to grow seed crops. Beets, carrots and onions are biennials. This means they produce seeds in their second year and then die. Because our ground can be so wet and cold through the winter, we often dig up these root crops and store them in a plastic bag or clam-shell container with dried leaves or straw so they stay moist (but not too moist) till we're ready to replant them. Below are pictures of beets (left) that have wintered over and are beginning to sprout leaves and root hairs. These we plant into pots with soil. On the right is a picture of a row of potted root crops that are developing enough roots and sprouts to then be planted again in the ground so they can mature and set seeds. Note: seed-saving can only be done with heirloom/non-hybrid varieties.

Our oldest greenhouse, the Ark, was ready for re-skinning this winter. The special UV-protected greenhouse plastic is guaranteed for four years but this skin actually lasted seven! We timed the removal of the skin for a few days that were forecast to be mild and with minimal wind. Donn came by after we got the skin off and the three of us got the new one secured in place with lathe in just a few short hours. LINK: Carport-Frame Greenhouse Design

Winter is the time for organizing our indoor spaces, sorting seeds and labels, pruning perennials and planting new ones...

After sorting seeds into categories, we put them in zip-lock bags (freezer bags) inside tightly fitting old peanut-butter jars (so they won't get dehydrated) and put them in our chest-freezer.

Llyn, sorting plant labels.

Keeping our garden supplies sorted and stored out of the weather...

Since we shut down our irrigation lines in the winter, we collect rain-water in buckets so we don't have to turn the lines back on till springtime.

Winter is time to care for our perennial plants: trees, shrubs, vines and flowers. Some need pruning. Some need mulching and our new ones need holes dug so they can live in their 'forever homes'.

Potted perennials protected from cold, north winds behind the house and under bags of leaves for insulation. These will get planted in the ground soon.

We're just days away from beginning to plant seeds in pots for next season's crops. 

May this be a fruitful and abundant year!

Lettuce: From Seed to Feed - Part 2: Saving Seed

By Llyn Peabody 

If you grow your own lettuce, as the weather warms, it's not uncommon to have some of it "bolt" (try to go to seed). Saving lettuce seed is fairly easy and a good entry-point for those new to the process. Here is a re-publishing of a post we wrote back in 2011 but the information is just as relevant today. Happy seed-saving :-).

Saving your own seed is an important aspect of developing local food self-reliance. Relying on commercial seed farmers may become increasingly unreliable as climate change disrupts weather patterns and seed crops falter. Growing your own seed slowly modifies your plants to be uniquely suited to your micro-climate and growing conditions. Networking with other seed-savers in your area builds a sense of community.

Lettuce flowers - close-up.

Seed-saving can seem intimidating at first. I know I felt that way. Many vegetables will cross with their neighbors yielding inconsistent results. There are many questions that must be answered before moving forward. For this reason I definitely recommend Suzanne Ashworth's "Seed to Seed". It is a comprehensive manual that covers all aspects of seed-saving. I am also grateful to my husband, Chris, for all he has taught me from his 40+ years of gardening. He's helped me translate the book knowledge into experiential learning. Saving seed appeals to the outlaw in me, I guess. Like treating illness with herbs I grew myself, there is something empowering about developing skills usually left to "the experts". As it turns out, it's not really that difficult at all.

"Red Sails" lettuce - blooming. "Red Sails" lettuce - blooming.

Saving Lettuce Seed: Like most things in gardening, a bit of forethought goes a long way. Ashworth recommends 12' - 25' separation between types of lettuce to prevent cross-pollination (the farther the better). Plan your plantings (and harvesting) to leave sufficient distance between the flowering plants. Though you may have enough time to bring a Fall crop of lettuce to seed, we usually do our seed-saving with the lettuce we plant in the Spring.

 

Note: Be sure there is no wild lettuce that is forming seed near the varieties of domesticated lettuce you are saving seed from as it can cross. The plants that grow from these crossed seeds tend to be more bitter and course. There are several varieties of wild lettuce; this one is named Lactuca Serriola LINK.

 Lettuce is an "annual" crop. This means that the plants will produce seed in one season (without over-wintering). As the weather gets hotter and drier you will notice on romaine or "leaf" lettuce a definite lengthening of the plant. ("Leaf" types form a loose rosette of leaves but not a tight "head). When it lengthens, it is starting to "bolt". Lettuce that is bolting gets noticeably more bitter (probably nature's way of protecting the plant in this important phase of its reproduction). On "head" lettuce (such as Iceberg), Ashworth says it can be helpful to slit the head, forming a cross-cut with a sharp knife, making it easier for the flower-stalk to emerge. She says some gardeners strike the head of the lettuce with the palm of their hand thus breaking the leaves away from the stalk. Without some effort to free the flower-stalk, head-rot from heat and humidity may kill the plant before it can go to seed. So far we have saved seed mainly from "leaf" lettuce. This summer we will experiment with our red and green "head" lettuces to see what works best for us and report back.

Lettuce marked for seed with bamboo. Lettuce marked for seed with bamboo.

As we are gardening with a group of people, we have found it essential to clearly mark the plants that we are saving for seed, so they are not harvested by accident. We have made small tipi's with bamboo sticks, tied a red ribbon around the plant or put a small sign on a stake and driven it in nearby. Even a plant that is obviously past an edible stage for harvest is not safe as a well-meaning fellow-gardener may assume the responsible thing to do is weed out your seedy lettuce plant and toss it on the compost pile!

Staked lettuce - the flowers get heavy. Staked lettuce - the flowers get heavy.

As the flower stalk grows it will produce a big head of flowers. You may need to tie it to a stake so it doesn't fall over. Seed production occurs 12 - 24 days after flowering. Ashworth says you can harvest seeds daily by shaking the stalk over a large paper sack. The ripe seeds will fall into the bag. The method we have used is to wait until the majority of seeds are ripe and to cut off the whole flower head and place that in a paper sack. Leave the sack open in a warm, dry place (like the top shelf your tool shed) until the flowers are thoroughly dry. Be sure to label the bag with the name of the lettuce variety. If mice are a problem and you have the space, try hanging the open bag from rafters.

To winnow the seeds, roll the flowers between your fingers and the palms of your hands to free them . Lettuce seed is challenging to separate because the seeds are not much heavier than the chaff. Patiently drop small amounts of the seed/chaff over a tray, from a height of a foot or two while blowing gently. The seed should drop and the fluff blow away. Some people run the seed through screens but we have not tried this method. Commercially available seed-sifting screens are another option. They have different sized holes.

Lettuce seed will remain viable for 2-3 years if kept in a cool, dark place, in an air-tight container.

Onions and Lettuce and Peas, "Oh My!"

Reprinted from February 2021: It's early Spring in the Sharing Gardens. Oh sure, we could still get plenty more freezing nights and even some significant snowfall before Spring is fully here but the first crocuses and daffodils are budding, the days are noticeably longer and the air carries hints of the earth's slow warming.  Since we have several greenhouses, February is the time for starting the cool-loving crops like lettuce, cabbage, kale, broccoli, collards, celery, parsley, onions and peas. We have also seeded beets and carrots directly in the ground in greenhouse beds. Here are some previously written posts about how to start some of these crops in your own garden.

Valentines Day: Time for Pea Planting: Since our soil outside the greenhouses doesn't really warm up enough to germinate peas till later in the Spring, we've developed a method for starting the peas in pots, in the greenhouse which we then transplant outside once the soil warms up and the plants can outgrow slugs and snails.

Lettuce: Growing from Seed: Lettuce is fairly easy to grow in our climate. You won't believe how sweet and delicious home-grown lettuce is compared to lettuce bought from the store! LINK

Lettuce: Saving Your Own Seed: If you leave a lettuce plant in the ground, very often it will "bolt" and go to seed (especially in the heat of summer). Lettuce-seed is easy to save and one plant can produce enough seed to grow lettuce for a whole neighborhood for years to come! That's "nature's economy" at its best! LINK
