Fall Blooming Bulbs and Corms

Colchicums

by Sandy Swegel

Colchicums! These huge flowers of Fall are still some of my absolute favorite flowers that I look forward to each year. They grow with virtually no attention and have thrived in a shady, pretty dry hosta garden that lacks color so much of the year. It’s been seven years since I planted them and I’ve never lifted them to divide because they look better and better every year! The only problem with colchicums is that you have to plan ahead and order them usually by mail order no later than August. Few garden centers stock them because they are so eager to bloom, they often bloom right in the box.

Colchicum Water Lily is the biggest and showiest and sells out every year from all the bulb catalogs. I first planted it in a shade bed next to a pond with water lilies because it looks just like a giant water-lily rising above the shady ground covers. It’s a fun plant because most garden visitors have never seen it and gasp breathlessly with “What is that flower?!”

A second colchicum I love is “Giant.” It has big single flowers and comes up sooner. Garden blogger Kathy Purdy made the most beautiful display of Giants I’ve ever seen by planting them densely along a low stone fence. In the fall garden with foliage changing and leaves falling, you need big showy flowers to catch attention.

Colchicums come in a range of colors including whites that are luminescent under Fall full moons…but the purple-pinks have my heart.

 

Finally, my third favorite Fall bloomer, also purple but much more diminutive is Crocus sativus. This is among the smallest of the fall crocuses, but you get real saffron from it. Not a lot, but ten bulbs I planted four years ago in heavy clay soil have multiplied to twenty and provide enough saffron for about three meals. It’s another delightful plant of fall that I watch with great anticipation for its surprise entry every September.

Stop the Powdery Mildew Cycle this Fall

Gardening Tips

by Sandy Swegel

Powdery mildew had a grand time in my garden this year. I often have a nonchalant attitude to it growing on a few leaves and don’t mind a little bit. But it started early this year on roses, then showed up on the bee balms and finished out the season inundating the sweet peas and squashes. By the time I paid attention, it was out of control.

But now it’s Fall and my inner lazy gardener says…ah well this season is over. Next year it will be different. But if we want to make progress against disease in our gardens, now is the time to act.

 

Do you Want Less Disease in your garden next year? Then take these steps now:

In the Vegetable Garden
As your squash and cucumbers and pea plants are dying back, remove those leaves and put them in the trash. Not in the compost pile. Don’t let them overwinter and deal with it in the Spring. Fungus and disease spores are sitting passively on the backs of those leaves, just waiting for rebirth next Spring. They do not reliably die in home compost piles. Powdery mildew will survive the winter by forming minute fruiting bodies called cleistothecia And tomatoes? I put the whole plants in the trash after frost. There are just too many diseases on them to risk.

In the perennial beds, leaves infected with powdery mildew like rose or phlox or bee balm often drop before Fall. Before the big tree leaf fall, I use the blower to blow the diseased leaves out of the bed and PUT THEM IN THE TRASH.

This vigorous sanitation is a good idea for all pests too. If you had bean beetles…get rid of those leaves that might have next year’s eggs.

But don’t be too clean.
That’s the important lesson here. In the non-diseased parts of the garden, ladybugs and lacewings and lots of beneficial insects are going to lay eggs and overwinter. We want them. I learned last year especially to let willow leaves be…there were dozens of beneficial babies at the base of willow plants last spring.

 

And next year…be attentive to the powdery mildew. I now promise to treat early and often with something gentle but effective such as horticultural oil or a baking soda. I lost a lot of production in my vegetables this year because I let the powdery mildew have its way. And the roses and phlox really took a hit. I’ll do better next year. I promise.

Ask Me Anything

Gardening Tips

by Sandy Swegel

Ask me Anything

About gardening that is. That’s what I tell people when I’m looking for blog ideas or a little fun.

So the answer this week in the form of a question was from my friend Jim:

“Why do sunflowers follow the sun but then all die facing the same way?”

That was a puzzler. I had to look that one up…fortunately there was just an article in August in the journal Science.

 

Sunflowers do follow the sun as long as they are still growing. The start off facing east and follow through the day facing west at sunset. Overnight, they grow and face east by sunrise.

This has long been known to gardeners and scientists…but Science answered WHY they do it. Because flowers that face the sun are warmer and attract more pollinators than those facing away from the sun. Well, that’s a good way to make sure you are pollinated. Very clever Mother Nature.

But then there’s the question of why they all face East when they die. It’s actually much simpler than that. Sunflowers only follow the sun as long as they are growing. Once they reach their full mature height, they no longer grow taller. The main stem thickens and hardens and no longer moves with the sun. It stops in a position facing East. So that’s naturally where it dies. Why? Again, it’s just to entice the pollinators. An east-facing flower warms up earlier and stays warmer longer during the day when most pollinators are feeding.

The one exception to this rule? Wild sunflowers. They have so many small flowers at all kinds of angles, they face every which way. Their leaves tend to follow the sun while growing, but the flowers are all over the place.

 

So, thanks for the question, Jim.

Next! Ask me anything you’ve wondered about gardening.

Bees Sleep

Gardening Tips

by Sandy Swegel

One evening near dusk in the garden, a gardening friend’s inquisitive granddaughter asked: “Where do bees sleep?”  This obvious question brought on a googling frenzy.  We could guess that honey bees might sleep in the hive. But what about the 4000 species of native solitary bees?  Hive-dwelling honey bees are a small percentage of the total bee population.

The answer should have been obvious:  Bees sleep on flowers! How adorable!

 

To be more precise, male native bees usually sleep on flowers.  When the female bees are laying eggs and raising young bees, they often sleep in solitary nests in the ground.

Sleeping on flowers has lots of advantages. It’s soft and very convenient.  You wake up and there’s breakfast (nectar and pollen) served in bed!

 

Some of my favorite stories of bees sleeping come from the squash bee family.  Squash bees spend their day inside a squash blossom.  As evening approaches, the male squash bee makes himself comfy as the squash flower wilts and closes around him.  In the morning, not too early, the flower opens again and the bee begins a new days foraging.  If the female bees have made nests, the nests are usually in soft dirt under the squash fruit.  So if you are growing pumpkins, it’s likely there are some young bees growing up under one of those pumpkins.

Foraging bees need the most sleep.  You’ll often find bumblebees taking an afternoon nap on a flower, all tuckered out from a hard day’s work. Younger bees and bees that do less foraging often just take short little 30 second naps.  Honey bees sometime sleep in the hive and sometimes they like to camp out and sleep under the stars. Next time you see a bee, motionless on a flower, don’t worry, it’s not dead…it’s just taking a nap!

Bird Baths

Eight critters you can find in your bird baths

by Sandy Swegel

Cute little birds hatched out of a nest in my roof eaves this spring so I decided to put a bird bath in the front yard so I could watch strategically from the window. I didn’t have traditional bird baths so shallow stone bowls on the ground had to make do. It’s been a couple of months and I have yet to see the birds in the bath although they may splash about when I’m not home. I have discovered lots of critters need water in the heat of summer. Here’s who shows up if you have a water source in your yard.

8. Wasps

OK, so they’re not my favorite although they have an important role in the garden. Wasps aren’t just insatiably thirsty, the water is crucial for keeping their nests cool.

7. Mosquito Larvae
Duh…standing water attracts mosquitoes. Since West Nile is prevalent around here, I empty out the water whenever I see the tiny larvae swimming around.

6. Raccoons
Fortunately, we don’t have too many raccoons in my yard, but if the birdbath is all muddy or knocked over, it’s a sign the raccoons were there.

 

 

5. Bunnies
We have a bunny overpopulation this year. Officially, I hate them. They chow down on young garden plants and my favorite flowers. Secretly they are so cute. It’s been so hot and dry who could deny a baby rabbit a sip of water. I guess the baby squirrels can drink too.

4. Bees
I always make sure there are rocks in my bird bath for the bees to stand on so they don’t drown. Bees need lots of water for digestion and to cool the hive.

 

3. Butterflies
Be sure to have nice shallow water to attract butterflies. These are so delightful! Even the cabbage moths are cute.

 

2. All the other mammals
Neighborhood dogs, deer taking a break from eating your flowers. If it’s a big enough bird bath, you might get a bear or two in bear country. My friends used a motion detector night camera to catch a bobcat drinking from their little water pond.

1. And finally birds!

Nurse Rock

Gardening Tips

by Sandy Swegel

Sometimes there’s a difficult spot in a garden when plants just keep failing. Or sometimes there’s a plant you really want in your garden (you know who you are butterfly weed) that keeps dying even though you think you are giving it perfect conditions. The easy thing to do is give up and plant a different plant or in a different place. But the determined gardener can reach into her magic toolbox of helpers for a Nurse Rock to give her plant the extra edge.

What is a nurse rock? Basically, it’s just a rock…most any old rock…that you strategically plant with your new plant. In hot arid Colorado, I usually plant on the north side of the rock so there’s just a bit more water and shade for the young plant. I learned about nurse rocks from a gardening friend who liked to grow the native plants she saw when she was out hiking. In nature, you’ll often see that plants are more likely to be growing near rocks rather than out in the open field. Even in your own suburban garden, you’ll see the edges of your beds or even your sidewalks have more robust plants.

There have been many scientific studies about why plants do better with nurse rocks. The obvious speculations are improved water, improved drainage, protection from sun, space from other plants, protection from wildlife, less evaporation, better soil nutrients under rocks and even more mycorrhizae. Old garden folklore highlights the image of the rock as a protector of the young plant from the big world.

 

I encourage you to give it a try. In the wild, nurse rocks are often large rocks a foot or more high. In the home garden, I’ve found even a small rock that fits easily in my hand gives a plant an edge. I’m trying this week with a spot in a narrow garden bed that just has had several different plants die out despite our ministrations. We’ve come up with reasons why the plants die…that one spot gets a little more sun and it a tiny bit higher than surrounding soil, or it’s a good hiding place for the bunny who ate the beautiful fall anemone down to stubs. We’re going to try again with an adorable small upright clematis, Sugar Bowl, and a good baseball sized nurse rock planted at its base. Thank you nurse rock.

Squash Bee

Peponapis: A Squash Lovin’ BeeSquash Bee

Jul 19, 2016 04:54 pm | thebeeswaggle

by Jessica Goldstrohm

Did you know some bees are very dependent on particular species of flowers?

This lovely bee is the squash bee, and I was fortunate enough to discover her, along with may others nestled inside squash flowers of a good friend’s garden! This was a very healthy and thriving collection of squash bees, and they are very specific to squash plant reproduction.

Squash bees are quite predictable in the flower preference they have; squash flowers, any type of squash flower, but it must be a squash flower.  They fly very early in the morning, sometimes before dawn seeking the opening squash flowers.  The females will spend much of the morning nestled inside squash flowers, circling the stamen of the flower, collecting nectar and pollen for their nests.  In fact, you will often find groups of squash bees within each squash bloom, absent of any conflict among them.

Squash Bee

My photos too!

Squash bees are solitary nesters, meaning they work independently to build her nest, lay eggs, and collect all resources for the eggs they lay.  However, they may nest in aggregations of hundreds, kind of like apartment buildings are to humans. We live next to each other, but we all lead separate lives.

Squash bees prefer to nest VERY close to their favorite flowering plants, so you will most often find their nesting holes in the ground under squash plants.  Females will retreat to he nest come rundown, while males find a nice squash flower to sleep in until morning.

This activity continues throughout the summer, and partway into fall, then all the existing bees die, leaving behind the next season’s generation nestled all in a row of egg cells containing adult bees.  This new generation of bees will hibernate until the following spring or early summer when the squash plants are flowering.  Squash bees are so particular about the flowers they feed on, that their lifecycle revolves around squash plants!

I’m sure you may have already arrived at the question of what does that mean for them when we go to clear the dead squash plants at the end of the season?  Well, too much deep tilling can lead to complete destruction of a mother bee’s hard work.  Squash bees nest approximately 1.5 feet straight down into the ground, so only rigorous tilling harms nests. Leaving some of the plant behind can serve as insulation to the hibernating bees through the winter.

Next time you see a squash plant, take a peek inside to see a group of squash bees, and look under the squash plant for any holes in the ground that might be a squash bee’s nest.

There you have it! Another native bee we depend on to get resources we all enjoy in the fall!  I can’t wait to have some zucchini from my plants, and pumpkin too!  So many things occurring right beneath our noses, and we miss them when we don’t stop and observe.

Cheers to joining the movement to save our bees!

Keep Your Sunflowers Blooming

Wildflower Seeds

by Sandy Swegel

Sunflowers inspire a primordial joy in us.  We may be rosarians, orchid specialists, rock plant lovers or even urban folk who barely see the outdoors, but sunflowers against a blue sky spark an inner gasp of delight.  Sunflowers often plant themselves on their own and can manage to grow without any attention from us, but if we have a nice little patch of sunflowers, we can nurture them so they last and last for weeks longer than their normal bloom.

What to do to get the most of your sunflowers?

Keep them deadheaded until the end of the season.

If you deadhead your sunflowers, they will keep pumping out new blossoms in their will to create seeds and more sunflowers.  Don’t cut the stalk way back, the next sunflower often forms just inches from the place you deadheaded.

Leave the very last batch of spent flowers for the birds and for next year’s flowers.

When it seems like the sunflowers are slowing down, do leave the last set on flower heads on the plant for the birds.  Even if its a little ugly going into Fall, birds like the seed heads right on the plant.  Little finches especially like to sit on top of the old brown seed head and bend over and pluck seeds out.

 

Give the sunflowers a splash of water

If your sunflowers have self-seeded into a dry back alley or someplace in hot sun, throw them a bucket of water once in a while during hot spells.  They’ll survive without the extra water, but thrive with it…and make more sunflowers just for you.

Moth Night

Pollinators

by Sandy Swegel

I love the things humans find to celebrate. Partying really is in our DNA. It turns out that nature lovers in East Brunswick, New Jersey actually celebrate moths for an entire WEEK and have proclaimed July 23-31 National Moth Week. At first, I thought this was a quirky group of nature lovers reliving childhood adventures of going out at night with flashlights, but Moth Nights are an international event (US, UK, Europe, Asia, Africa)! The UK has celebrated Moth Night for hundreds of years. Switzerland and Hungary have European Moth nights and I’ll bet if your town doesn’t have Moth Night now, park services will be sponsoring them soon. It’s fun (all you need are bedsheets and flashlights, maybe some blacklights), environmentally conscious (moth counts and keeping track of endangered species) and a great family event.

 

Why moths? This is what the National Moth Week people promote:

* Moths are among the most diverse and successful organisms on earth.

* Scientists estimate there are 150,000 to more than 500,000 moth species.

* Their colors and patterns are either dazzling or so cryptic that they define camouflage. Shapes and sizes span the gamut from as small as a pinhead to as large as an adult’s hand.

* Most moths are nocturnal, and need to be sought at night to be seen – others fly like butterflies during the day.

* Finding moths can be as simple as leaving a porch light on and checking it after dark. Serious moth aficionados use special lights and baits to attract them.

And here at BBB Seed we add one very important reason to celebrate moths: they are POLLINATORS for night-opening flowers!

 

Take a look at moths this week. In my garden this week there is the ubiquitous pretty but destructive cabbage moth and the amazing hummingbird hawkmoth, both visible in the daylight. You can have your own “Moth Night” by hanging up a bed sheet on your clothesline and propping a UV black light behind it. Or just sit on the front porch with the light on!

The Aster

Wildflower Seeds

by Sandy Swegel

July is when the aster begins to shine in the garden.  We were walking around a hot drought xeric garden yesterday where many flowering plants were going to seed (ah, flax and larkspur we miss your blues already) or had complete browned and been cut back (goodbye poppies).  Amid the browning foliage, there were splashes of color we forget about each year like the amazing Zinnia grandiflora, a very short aster, native to plains and foothills, that thrives along hot concrete walkways.

 

Standing near this tiny aster, we could look up to the back of the garden where there was a bit of shade and moisture and see tall asters in full bud.  In the sunny grassy open space nearby, purple asters had already bloomed and were feeding pollinators and butterflies. We looked to a neighbor’s irrigated garden and saw a splendid patch of Michaelmas daisies ready to bloom with hundreds of flowers.  Aster may have small individual flowers, but they cram dozens of flowers onto each flower stalk.

 

Asters aren’t very picky about location and in cities, you’ll see they seed themselves into alleys and sometimes into your flower beds.  In fields, the purple asters often grow one plant here and one there out among uncut grasses.

The very best thing about asters:  butterflies love them.  And we definitely want to keep the butterflies happy.
