Helping Bees Help Us

Honey bee gathering pollen

Outside the birds are chirping like crazy in anticipation of this year?s nesting activities. The bees are becoming more active every day searching for nectar in the flowering trees and shrubs. Ceanothus season is coming soon and then they?ll really be busy. Last year was a banner year for my native bees and bumble bees. There were also a lot of European honey bees around. Maybe I was just lucky. What can you do to help our pollinators in these times of diminishing habitat, disease, climate change and pesticide use?

There are 1600 species of native bees in California with several hundred living in Santa Cruz county alone. They are solely responsible for pollinating many of our native plants. Being solitary they do not make a hive but make nests underground or live in wood, one female per nesting hole and she lays her eggs there. Leaving areas in your garden near flowering plants un-mulched helps her find a nesting hole. The hard working females mate, make nests, collect pollen for their young and lay eggs. Males live to mate and only pollinate inadvertently when they visit flowers for nectar to fuel their flight.

Long-horned native bee

Common native bees in our area are the yellow-faced bumble bee and the long-horned bee which has stripes a little like a yellow jacket. The hard working bumble bee is easy to identify from its bight yellow facial hair and yellow bands on their backs and abdomens. Female bumble bees? hind legs widen to form pollen baskets often filled with bright yellow, moistened pollen pellets.

The long-horned native bee gets their name from the long antennae of the males although the females do not have this. Males may be seen by day jostling for female attention above a patch of blooming plants while the females are collecting pollen. Only the females have branched hairs on their legs for carrying pollen.

Bees eat two things: nectar which is loaded with sugar and is their main source of energy and pollen which provides proteins and fats. Some of the common native plants that are recommended for our area to attract bees of all types include yarrow, columbine, California poppy, coral bells, silver lupine, penstemon, ceanothus, toyon, big leaf maple, mahonia, monkey flower, buckwheat, western azalea and purple sage.

Common garden plants that can attract bees to your landscape and vegetable garden are herbs such as African blue basil, oregano, mint, catnip and cat mint, borage, rosemary, chives, hyssop, dill, comfrey and fennel. Edibles that attract bees are blueberry, pumpkin, squash, sunflower, blackberry, hazelnut, artichoke, beans, cucumber and peas. Crabapple, iris, lavender, salvia, sunflowers, monarda, aster, butterfly bush, sweet alyssum, alstroemeria, red hot poker, gloriosa daisy, scabiosa, coneflower and echium also attract bees of all types.

Honey bee searching for nectar and pollen

The higher temperatures that come with climate warming can affect a bee?s ability to detect a flower?s pollen. A flowers scent is what tells a bee that nectar is present. If the weather gets to hot the plant will spend less energy on producing fragrance and just try to survive. When flowers stop emanating these enticing smells, some bees have a tough time finding food and may abandon certain area. Studies have shown that warming climates already have affected our central coast bumblebee population during the past 30 years especially the California bumblebee.

In your own garden an abundant and healthy population of pollinators can improve fruit set, quality and size. Crops raised in California depend on both domestic honeybees and native bees for pollination of almond, blackberry, cucumber and artichoke crops.

Honeybees and native bees need help to survive and we’re the ones to give it. Besides planting nectar and pollen sources you can help by buying local honey which support beekeepers.

Just a Few of the Plants Blooming Now

Fragrant Blireiana flowering plum

Some years plants bloom a couple weeks earlier than usual but not this year. Our February weather put many plants on hold. Nature?s catching up now. Outside my window the Blireiana flowering plum is covered with dark pink, double blossoms. It’s one of my favorite spring blooming trees with a sweet fragrance strong enough to scent the garden. It usually blooms in February in time for my birthday but not this year. Worth the wait. We all look forward to the earliest flowers of the new season. Spring officially began on March 20th.

Forsythia

The cold and rainy weather didn?t stop an old fashioned shrub like forsythia from blooming. They figure prominently in many old gardens because they are tough plants, able to survive neglect and still look beautiful. The bare stems of forsythia are completely covered with deep golden-yellow flowers in late winter and early spring and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety ?Kolgold? in the 1800’s. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Flowering quince

Flowering quince is another old garden staple providing early color. They are easy to care for and nearly indestructible in almost any soil that is well drained and not overly fertile. Once established quince is a very drought tolerant plant and their spiny branches make them an excellent choice for hedges, screening or as a security barrier. There are red, pink, orange and white flowering varieties. The Toyo Nishiki cultivar even has pink, white and solid red flowers all on the same branch.

Yellow clivia

Buds are just starting to form on my clivia or Kaffir Lily. What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters that emerge from between dark green, strappy leaves. Even in dark shade they will bloom and brighten the late winter/early spring garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivias are hardy to several degrees below freezing. I have a yellow flowering variety also but I?m not seeing any buds forming yet. Possibly it?s too young. Clivie bloom best when crowded.

Hardenbergia ‘Happy Wanderer’

A beautiful vine that blooms at this time of year is hardenbergia ‘Happy Wanderer’. In the pea family, this evergreen vine looks like a small wisteria when in bloom. Pinkish-purple flowers cascade in clusters on twining stems that reach 12-16 feet long. They require little water once established and are hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn’t live without is Fragrant Sarcococca. The tiny white flowers of this plant are easily overlooked but you can’t miss their scent. I have one near the front door that greets me with that vanilla fragrance every time I walk in or out. The flowers are followed by a bright red fruit. Sweet Box forms a natural espalier against a wall and if you have a problem spot in deep dry shade where other plants won?t grow give this plant a try. They are easy to grow, deer resistant and trouble free.

Aloe & other Succulents in the late Winter Garden

Usually succulents are bullet-proof in the garden. Easy care, low water and dramatic they are great additions to the landscape. If you are having problems with fungal spots on yours after so much rain and cold you?re not alone. Still aloe, yucca and agave are worth growing as well as other succulents. Here is some useful information.

Cape Aloe

Succulents have demonstrated a wide tolerance to the fungi that cause leaf and some spots. Although they can disfigure plants they do very little damage despite their appearance.

There are other more serious fungal infections like anthracnose. It often appears as a moist tan colored rot with red, orange or pink pustules on the surface. Spots start small, but expand rapidly on both leaves and crowns. Once a succulents is infected the only treatment is removal of affected leaves. The application of copper fungicide may help to destroy fungal bodies. Root and crown rot don?t respond well to treatment and if you have planted your succulents in well draining soil there might not be much you can do about the excessive rain they?ve gotten recently.

Our Mediterranean climate is usually perfectly suited for the exotic looking family of Aloes. Some hail from the Arabian Peninsula and Madagascar but mostly they are native to South Africa. The spikes of their showy flowers supply much needed nectar for hummingbirds now when not much else is blooming.

There?s a variety for any space, large or small, container or tree-like. Here are a few of the types I?m seeing blooming right now in our area.

Aloe ferox

Aloe ferox or Cape Aloe grows best in full sun but tolerates a wide variety of growing conditions. They can thrive in very dry conditions or grow in an area that receives regular irrigation- a good trait given our recent wet winter. The foliage is hardy to at least 20 degrees and the winter flowers down to 24 degrees. Cape aloe grow to 6 feet tall and 3-5 feet wide so plan accordingly if you plant one of these spectacular reddish-orange to orange succulents. Cape Aloe occupies many habitats in its native Cape Region of South Africa and is listed on the endangered plant list.

Torch aloe

Torch Aloe or Aloe arborescens blooms also in fall and winter. The bright yellow or red flower spikes cover this large clumping variety. This species has recently been studied for possible medical uses similar to the well known aloe vera plant. It?s the only other member of the Aloe family that is claimed to be as effective. It can survive much lower winter low temperatures than aloe vera.

Aloe vera has been grown for thousands of years in tropical climates. It is one of the most widely used medicinal plants on the planet. As a houseplant make sure the pot has plenty of drainage holes as they cannot tolerate standing water. Let them go completely dry between waterings and grow them in the very bright light of a south or west facing window.

The Soap Aloe or Aloe maculata is so tough that it can survive just about anywhere. My soap aloe aren?t blooming right now but others in better growing conditions are sporting showy flowers atop tall, multi branched stalks in colors ranging from red to gold. Once established this succulent needs only occasional water to look good. They grow in partial to full sun. The foliage gets 18 to 24 inches tall with the bloom spikes reaching 35 inches tall.

Every garden should have a variety of aloe to feed the hummingbirds in winter.
