New Addition: Paperbark Maple

paperbark by patioI love it when a plant is described as a “solution.” But that’s not what led me to select and plant Acer griseum, commonly called a paperbark maple due to its distinguising feature of peeling bark. T

No, I chose this tree because my yard is small and I wanted a smallish tree that would give more of an enveloping feeling to the space at the patio’s edge. We all know site selection is important when buying plants, and I’d say it’s very important when buying trees. They’re expensive and not easy to rip out like, say, daylilies or other type of perennial.

paperbark maple2So I considered not just my need for a more cozy spot, but also the fact that the site gets mostly full sun, is made of clay soil and I wanted to reduce the step down from the patio to the yard. Beyond these technical considerations, I wanted a tree that provides fall or winter interest. Winter is St. Louis is dreary. I like looking out something beyond a gray landscape. So far, additions of a drawf blue spruce (looks awesome in snow!) and winterberry have helped establish more four-season interest.

Paperbark maple site prep

Here’s a “before” photo. We had lots of rain this spring so there was a considerable lag time from when I bought the tree and when the landscaper could plant it. I prepped the site by killing the grass with glyphosate.

paperbark install2I’ve thought long and hard about what I wanted in this spot. Maybe an attractive shrub row with great fall interest, such as burning bush (euonymus alatus), or a tree that would provide dappled light, like river birch (betula nigra). I love the peeling bark of river birch, but I don’t care for its leaves all that much. A row of shrubs would obscure my view of my shade garden and would be too much of a repetition in size; I already have several shrubs of similar height. Oh, and I like clumping or multi-stemmed trunks.

peeling bark mapleOf course, I did lots and lots of online research and visited my favorite nurseries and the Missouri Botanical Gardens once or twice to look at trees I that interested me. By the way, MoBot has a wonderful plant finder tool on its web site. This is what a came across when I did a search for paperbark maple:

Attaining a height of 20 to 30′, paperbark maple is an excellent choice for small properties. This slowgrowing tree features beautiful peeling cinnamon to reddish brown bark and trifoliate leaves that turn red in fall. Its two-winged seeds tend to be infertile and will not produce as many unwanted seedlings in lawns as other maples.

Other pages on the MoBot web site describe the tree as a great choice for clay soil. Problem solved. The tree is larger than I can manage so a local landscaper planted it for me this spring. If I have one regret, it’s that the paperbark is a slow grower. It’s going to take a few years for it to fill in and lend that enveloping feeling I’m seeking. But all things considered, I would definately describe this tree as a “solution.”

The Beauty of Garden Accents

happy leaf manJuly has been a splendid month. Very hot, very humid but full of travel, fun and frivolity. Isn’t that what summer is supposed to be about? I’ve left the garden to its own devices and have been welcomed back by a host of new bloomers–panicled hydrangeas, black eyed Susans, Joe pye weed, pink roses, daisies and zinnias, even as the voles continue their vicious attacks.

Wind chimesA 4th of July visit to my sister in San Antonio is what has inspired this post. Mornings were spent lounging on her tree-covered patio, coffee mugs and i-Pads for news in hand, interspersed with lots and lots of sister talk. Surrounded by Susan’s lush plantings, pond, and all sorts of of garden ornamentia my thoughts were naturally led to garden art.

Stone birds

Ribbon grass, now mature, provides a backdrop for the stone bird post.

I love garden accents. They provide a punctuation mark, whimsy or a much needed pause to the garden. Garden accents can take the form of some serious statuary or be as delicate as a glass wind chime. Big or small, I believe such accents give the viewer information about the garden and, more importantly, the gardener.

Fence hanging

I often buy garden accents as gifts. Sometimes they don’t make it to their intended recipients, as is the case for this blue glass bead dangler.

As my backyard playground progresses, I’ve slowly added small pieces to the yard, mainly to begin to fill in blank spaces in garden beds or to visually fill up the vertical void on the large fences. I like more natural and organic materials, such as unpolished stone, woods and rusted metals. And I love hearing the metal tones of chimes in the wind.

A mermaid marks the garden and memories of many trips to the beach and exotic islands.

Travels provide a great excuse to buy a little something for the garden. I bought this smiling leaf bird feeder during one of my travels. It reminds me of the trip I took and the cute garden shop I visited. Conversely, travels often inspire a local purchase. I like mermaids because they remind me of wonderful island trips I’ve taken; I bought a metal mermaid at a local art fair.

clematis amillaryGarden ornaments also fulfill a function. They provide a structure for climbing plants, a resting spot for birds or even a stand for plants. The small armillary sphere in my raised garden bed has been a good climbing structure for the young clematis I planted last summer. Form can meet function and be artful at the same time. One of my friends created a beautiful privacy screen with custom-designed panels.EmilyDSCN4839The plant stand  above (a sundial base, really) has held containers full of caladiums, a basketful of fern and now an armillary sphere. But I placed it here to provide a focal point to the astilbe that surround its base and to fill up the fence line.Stars on treeI’ve also repurposed objects d’art for the garden. A swag of wooden stars originally used for a Christmas mantle display has been repurposed to dangle from a tree. It was getting zero use sitting on a shelf in the garage, now I enjoy it whenever I am out on the patio. I also found a couple of pieces of rusiting tin ceiling tiles at a resale shop that I’ve put to good use on the fence. I think they provide a whole lot of look for the $3 I spent on each piece. In the spring, my neighbor’s bright honeysuckle is a pretty contrast with the rusting metal.Rusted ceiling tileHow do you accent your garden?

Hot for Hostas

DSCN4664Hostas have so many of the elements I look for in a plant. Easy to care for. Can be divided. Comes in lots of varieties, both big and small. But truth be told, I’ve not always been a big fan of them–even though they have been in every garden I have planted. You’d be hard pressed to find St. Louis garden that doesn’t incorporate hostas into its design. These are workhorse plants in this part of the Midwest and they go well in many applications.

hosta by rosesMy fondness for hostas is growing. This plant is an essential element to my shade garden and I enjoy looking at them every day. I love the hosta in the photo above (taken in May) but will probably move it next year. Even though it is encased by the oakleave hydrangea, which filters the sunlight, it gets too much sun and by July it looks like its about to burn up. There are “sun loving” hostas but don’t be fooled, this is plant really a shade lover.

DSCN0734

Too much sun? Not enough water? Both I’m afraid. I got wise and moved any hosta in this area and, yes, upped the water.

So why the growing affection for this hardy perennial? As they say in real estate parlance: Location, location, location. That’s right, I think I have finally found the right spot for them. And, I like the mix of perennials they’re planted with. Shape and texture, the keys to any garden, really stand out in a shade garden. Some have larger leaves than others and they are mingling in the bed with the tall, delicate shapes of fern, deeped lobed leaves of heuchera, spikey and brightly colored Japanese forest grass and the serrated leaves of astilbe, whose plume is to die for.

DSCN4401

The blue hue of “Frances Williams” (center left) stands out against all the other green in the garden bed. This variety is a welcome contrast to the bright green Japanese forest grass (hakonechloa).

 

frances william

Hostas like water and Frances Williams is no exception.Its leaves become wider as it matures.

Moisture is another important consideration when placing hostas. I have learned the hard way that they do not do well in dry shade. Mine are mostly planted in a bed with a bunch of other moisture lovers, mainly fern and astilbe. They also like slightly acidic soil which is in abundance in my garden.

Hosta’s flower is nothing to speak of so its appeal is its foliage. I’ve planted hostas whose foliage have a spectrum of hues from citron with greenish/blue streaking to blue with creamy yellow edging and deeper green with white edging.

 

DSCN4602

I’d like to share with you the names of the hosta varieties I have in the yard, but I don’t know them. Many of the plants in my garden are from the local area garden club sales, friends gardens, or were in the yard when I moved in, and they didn’t come with a tag describing their variety. Because they grow so well in our USDA Zone 6a climate, I am a big fan of dividing hostas and placing them throughout the garden beds.

Surrounded by flowers in garden beds edging the patio, the cool shade bed is a welcome sight.

Beware of the Vole in Your Garden

DSCN4509

My beloved penstemon is taking a beating.

Ugh. Something is making itself awfully comfortable in my yard and gardens. And I believe it is a vole–or more accurately, voles. Given their voracious habit of reproduction, I’m sure it’s the plural form of this noun.

Regardless, they are beginning to wreak havoc on some of my garden favorites, like my penstemon, which is listing and appears to have some heavy root damage.

DSCN4574

First sign of damage: plant laying down and roots exposed.

DSCN4571

Close up of root damage.

At first I thought it might be moles, but my research leads me to believe it is voles, commonly referred to as the meadow mouse. Apparently moles will leave mounds of dirt resembling small volcanos in its wake. Not so the vole. Multiple small holes are the hallmark of this rodent. Because both like to tunnel throughout the yard, the mole is often blamed for the havoc of the vole.

DSCN4589

Clear over on the other side of the yard, the coreopsis has fallen over and the roots appear damaged. Note the small hole on the right near the edge of the plant’s foliage.

DSCN4578

When I first saw the holes they were near the edge of my raised bed and I thought it was just signs of the soil settling. I even added new soil this spring. The beds were installed last year.

In casual conversations with friends, I’m learning voles are relatively prevalent in the area, at least the 3 of 3 conversations I’ve had in the past two days would confirm that. In fact, it was not 1 hour after talking with a friend who has voles, that I actually saw on the creatures–clearly startled by my presence–quickly dive into its hole by the flagstone. All have cautioned me to take swift action. My research via the Missouri Botanical Garden website confirms that as well. Apparently voles can do some very serious damage to the garden. On anthother note, one of my friends told me she and her husband have a “vole guy.” I had to laugh at that and get his number.

On a high level, here is what I’ve learned:

  • Voles are herbivores, not like the mole, which is a carnivore.
  • They begin reproducing at three weeks of age and don’t stop until they die., with litters of two to nine created monthly. Fortunately, their life span is only 16 around months in the wild.
  • They overwinter in their tunnels, enjoying the food they store in hollows near their nests.
  • They make elaborate tunnels throughout the yard.
  • They enjoy the tender roots of young herbaceous plants and the bark of young trees.
  • Habitat management, traps, repellents and chemicals are treatments to rid voles. Chemical warfare to rid this pest is probably not that effective in the spring/summer when the vole has lots of food choices at its avail.

Have you treated your yard and garden for voles?

Salad Gardening Experiment Update

Salad fixins

Lettuce, spinach and broccoli grow from seed in my veg trug.

I’ve enjoyed my first home grown salad of the season. Tender lettuce and spinach leaves gingerly harvested from the veg trug. Truly a satisfying feeling. A salad that was fresh, delicious and grown from seed in my own backyard.

Yet I seriously doubt I will grow vegetables from seed again.

DSCN4483

Freshly picked, washed and ready for tossing.

It’s not that I didn’t derive a great sense of accomplishment from harvesting my own salad fixins. I did! Honestly, though, I did not enjoy the growing-from-seed experience. I did two experiments: Starting seeds in eggshells (what I affectionately call The Pinterest Salad) and direct sowing seeds into my veg trug (what I call the No-Fuss-No-Muss Salad). And if I had to choose one over the other, I prefer the latter.

Daily I misted the eggshells and the seeds quickly began to sprout. Joyous, I envisioned gently positioning my eggshell seedlings into the trug beside the No-Fuss-No-Muss experiment. The race would be on! But wait, what’s this? My eggshell seedlings became…leggy. Apparently my bright sunny window was not enough. I actually needed a grow light which would provide the appropriate light so that that lettuce would grow bushier.

Uh-oh.

egg carton growing (960x1280)

Leggy lettuce, broccoli and pelargonium get their start in eggs shells.

Meanwhile, the seeds in the trug were, well, trugging along. They were very slow to get going. Day after day little progress greeted my pre- and apres-work inspections. Was I watering enough? Too much? Not enough sun? Too cold? I moved that trug from sun to shade to partial sun/partial shade. Time would soon tell. Wouldn’t it? The broccoli plant looks wonderful but has yet to bear broccoli.

Veg Trug April (960x1280)

Direct sown into the veg trug, spinach and lettuce begin to sprout.

 

I decided this was too much anxiety for a salad. But patience saved the day and eventually the lettuce and spinach produced lovely leaves worthy of picking and drenching with salad dressing. It occurred to me that I should have written down the date I planted the seeds so that I could generally expect when they would mature. (I think I was looking out the window during science class.) The brocolli has yet to produce.

I continued to mist the Pinterest Salad. I had read that blowing a small fan near the seedlings would strengthen their stems. Whose got time for that! It’s no wonder I prefer the No-Muss-No Fuss method to salad gardening. I eventually took my Pinterest Salad outside and attempted to plant the eggshells in a small pot. That did not work. The shell fell apart and the seedling root structure was far to fragile.

Next year, I will fill my trug with salad fixins, but I plan to buy small starter plants from the nursery, which I expect will be equally satisfying.

Do you grow vegetables from seed?

5 Container Favorites

I don’t talk about annuals much, preferring to invest in perennials and shrubs. But I do a bit of container planting each year to keep the color going. I’m anxious–but not too–for this cool, rainy spring to turn over to summer where the containers really take off. Every year I like to experiment with something new but I do have some tried and trues that I can’t live without. Here are five of my recent favorites.

 

2015 nicotianaNicotiana. I plant this near a window so I can enjoy its evening fragrance. A fast grower, nicotiana attracts bees and likes sun. Nicotiana comes in pink, a limey green and white. I like the white but have planted all three. I don’t usually combine this in a container because it likes as much room as it can get.

Trailing begonia 2Begonia. Not just any begonia. It’s gotta be dragon wing begonia. The light my window boxes receive suits this plant just right, and dragon wing has become a staple. I usually pair them with a spiller because these plants are all the thriller I need! Here I’ve paired it with purple spiderwort, another easy grower. I’m partial to the coral blooms that gently cascade on a delicate stem. As you can see, they take over, but I’m not complaining.

DSCN1945 (960x1280)Angelonia. I’m fairly new to this gem of a plant and I find the white cultivars are a bit more vigorous than the purple. However, I’ve only planted these in containers for two seasons and last season my containers (which had the purple variety) really didn’t perform well. This container had both white and purple varieties. I adored the yellow accent of calibrachoa, but it only bloomed once and looked pretty shabby.

Gerbera pot (600x800)\

Gerbera Daisy. Happy, hardy, colorful. A friend brought this over one day. I popped this sunny flower into a sunny yellow pot and enjoyed the heck out of it all summer. This is an easy care perennial that performed best in a container. It did not take well to being transplanted.

Gomphrena containerGomphrena.  I wish I had a better photo but you’ll get the idea. This is a real workhouse annual, providing bloom after tireless bloom all summer. Its cute pom-pom shaped spheres on long thin stems make for a great fill-in. I planted this last summer for the first time and combined it with sweet potato vine and petunias. I’d categorize this plant as fun, if there is such a plant category. The nearly neon purple bloom is a lot of fun too.

Ewwwww, What’s That Smell?

DSCN4376

The marketers of the rain barrel say this is a good spot for a plant. I don’t think so. It would block the overflow hole (see picture below). Also the front has a lip of sorts to also allow rain to cascade down the front. 

Here’s a rain barrel update. The water stinks.

In about one short month’s time, I have noticed that the water coming from  each of the two barrels has an malodorous quality. There’s also a slight greenish/yellowish tinge to the water. This was not the case the first couple of weeks of use.

DSCN4374

The barrel relieves itself of water when full. The lip at the top also releases water when full.

While I knew there’d be some maintenance needed, I didn’t think it would be so soon.The barrels have a small screen in the top where the water drains in. Other than that, the system is completely enclosed. There is no removable lid, which in hindsight may not be ideal for dealing with clean out issues. I do know that there is no critter in there and there is no leaf/treat/plant debris in there because the opening in the screen is too small.

DSCN4375

It’s amazing the amount of debris that comes off the roof.

I immediately turned to the Internet for help in diagnosing this problem.Probably causes: pollen in the water, algae growing in the water. Apparently it is not uncommon for the barrels to take on an odor during the spring pollen season as the pollens are deposited in the barrel along with the rain. The common antidote seems to be to drain the rain barrels or to quickly use the water following a rain.

I’m not going to do that. Both remedies seem counterintuitive to having them in the first place. I don’t want to get rid of all that water I am capturing in an effort to keep it out of the sewer system. And, my garden doesn’t typically need to be watered right after it rains. Especially in the spring when the temperatures are mild.

Another common cause for stinky barrel syndrome, as I’ve decided to call it, is standing water at the bottom of the barrel. Obviously that is not my problem. My barrel has two spigots–one up high and one down low. The lower spigot is near the bottom so that should not be a problem as I get into the dog days of summer and am draining them to water my thirsty garden.

What to do? What to do? I needed to find a remedy for the smell before it became too awful. And there are lots of ideas out there. Add baking soda to the barrel. Add vinegar to the barrel. Add baking soda AND vinegar. Add bleach. Install the barrels in a shady spot (now you tell me!). Add cedar oil or cedar chips to the barrel.Use a commercial algae killer. And there are those who say leave it alone, the microorganisms in the water are good for the plants.

Further research poo-poo’d the vinegar idea, saying it will only make the problem worse. I decided to add 1/4 cup of bleach to the barrel. It seemed the quickest solution I have on hand. I have only taken a small amount of water from them since I did this because we’ve had lots of rain (about 2 inches this week) but I didn’t notice an odor. Is it because of the fresh water coming in and displacing the funky water or is it the bleach? Time will tell.

How do you keep stinky rain barrel syndrome in check?
