At A Glance: A Run Of Cold And Rainy Weather

August 16 2014 020We have had a long run of cold and rainy weather.  As in overnight temperatures in the high 40′s and low fifties, and close to 6 inches in one day, last week.  I don’t think the pink fittonia has grown an inch.

August 16 2014 047However, this variegated tradescantia is really thriving-the color is so beautiful. It almost looks like it is blooming.  I will plant this again, no doubt.

August 16 2014 002The begonias have held up amazingly well in the cold rainy weather.  The caladiums and alocasia are so so-I would guess they are shuddering from the cold.

Aug 16 2014 004The Persian Shield on this north wall is such a beautiful iridescent purple. In full sun, the leaves green up-the resulting purple/green mix is a muddy color. This pot is holding its own.  I have had the Persian Shields grow 3 feet in a single season.  Not this year.

Aug 16 2014 002This lavender New Guinea impatiens is completely out of bloom, but is setting buds. They hate chilly weather.

Aug 16 2014 003The nicotiana has had quite a bout with white fly. I can’t remember ever dealing with that before.  I sprayed the foliage with water every day.  Who knows if that helped.  The cold may have slowed them down.  I don’t see them anymore, but the nicotiana were damaged. The coleus is filling in for them.

Aug 16 2014 013The plants in this pot seems to be thriving.

Aug 16 2014 005The cool and rainy weather has not fazed the heuchera one bit. They have put on some weight.  Aug 16 2014 007The geraniums have not been happy.  They like it hot, and on the dry side.  But these Caliente geraniums are bravely budding up.  It is hard to keep a good plant down.

Aug 16 2014 009The scented geranium topiary is shedding interior leaves.  This is a sign of water stress-either too much, or too little.  The scotch moss is loving the sun, the rain, and the cool.

Aug 16 2014 010I have no complaints with the Italian olive jar.  Every plant is bearing up, in spite of the unseasonably wet and cold weather.

Aug 16 2014 012Container plantings are a joy, and a trial.  Our summer has been cold and cool-no tropical plant loves this.  I keep hoping for that warm up that never comes. By this time of year, my deck pots are usually overflowing.  Do I have any complaints?  Not really.

014I could be looking at this.

 

 

 

 

 

Peak Season

 

The containers on my deck have grown like crazy in the past month-we are  approaching peak season.  The weather has been perfect; most days have been sunny.  Even so,  we have had night temperatures lately in the 60′s.  There are signs of summer’s end, as much as there are signs of summer’s peak. Though I could easily do with this weather a few more months, September 1st is just 2 weeks away.  Once labor day comes, our summer is in decline.  The nights are colder; it seems like less heat and energy comes from the sun.     Annual plants grow and bloom with one end in mind; they need to set seed, before they are done in by frost.  This is an exhausting task. All the while my container plants are putting on size and blooming great, there are signs of stress.  The mildew I have struggled to avoid on my dahlias-it has claimed a few stalks.  The fancy leaved geraniums pictured above are so rootbound I have to soak them every day.  The Japanese beetles have discovered my canna flowers.  The coleus despises the cooler night temperatures.        

The mildew seems to be spreading to my petunias, for heavens sake.  And the aphids on my licorice-this is a first for me.  Do all of my containers grow to perfection-not even close.  Just close enough to provide me with a lot of pleasure, looking after and at them.  There are a few things I do to make the best of the last leg of the summer.  I do feed my pots with liquid fertilizer regularly.  Geraniums like lots of feed-ferns, not so much.  Each one of my containers has a lot of plants in them, or plants that have grown large. I soak my pots with water, and then soak them with feed.  Liquid feed is like a shot of B-12; I avoid the next watering as long as I can, so the plants benefit before a watering washes it all away.  I am sure to flush my pots through between waterings, to prevent a build up of salts that can become toxic.   

  Most of my containers have grown skirts by now.  When I water, I lift the plants up so I can see the soil.  I water the surface of the soil-not the plant leaves.  There is no sense encouraging mildew to spread. I soak them thoroughly, and then let them get quite dry. The rectangles on my north wall only get water twice a week.  Overwatering begonias in hot weather is asking for rot.  Caladiums will hang their heads when they need water.  I snap off the old leaves out that get too tall, and threaten to engulf my chartreuse Janet Craig dracaenas. 

Growing plants in containers is a live and learn proposition.  As in-this rainbow coleus is a very big grower.  This means there are big sections of stalks between sets of leaves.  This makes it tough to get a good shape from the plant in a container.  These Italian terra cotta urns look like they have top hats-funny, this.  This variety would make a great hedge in the ground.

I know Milo is pretty handsome, but the message here is about keeping things clean.  I remove dead or diseased foliage.  I sometimes thin plants to improve air circulation. And I pick up what falls on the ground.  I leave no debris.  What I would gladly let decompose in my garden I don’t think is good for my containers.  My big Norway maple is raining disease ridden leaves; I pick them up, and throw they away.  Fungus can live over the winter.  Sometimes clean gardening practices is your only defence.      

My terrace is my version of a kitchen garden.   Buck cooks here, and I look after the pots.  My small bi-level deck has 14 containers.  It is a rare evening that there is not something to putter over-I like this.  I only get into trouble when I let them go too long.  Consistent attention is much better than an occasional look.  Hauling the containers here from the basement, filling them with soil, and planting-that’s real work. The work now is not that tough, and at some time during the process I plain start to feel better.  

The jumble pot of petunias and trailing verbena has been great, and still looks great-even on the inside.  I have been very careful to pick up the plant mass hanging over the edge, and deal directly with the soil.  I have kept this on the very dry side-a strategy that seems to be working.     

I only had one shot left on my camera before the battery died the other morning.  The pink light at dawn-wow. My little garden is anything but perfect, but at moments like this, I am very glad to have it.

Green Schemes

Containers planted with an all green color scheme can be very beautiful.  Eliminating color as an element in container design means that other elements, such as texture, mass, form, scale, and proportion, become very much more important.  The frosty white Victorian parlor ferns in this planter are a lacy contrast to the big leaves of the white caladiums.  The languid and lax habit of the tradescantia fl. Variegata contrasts to the tight soil skimming habit of the lime green club moss, known as selaginella.  Overall, the planting is loose, and airy-just like the container.  The container itself is such an important element of the overall composition. 

I planted this pair of Italian pots with 2 gallon size zebra grasses, and finished up all around with lime variegated plectranthus.  The colors in one plant mirror the colors of the other-so all of the visual interest is the contrast of the tall narrow grass blades, and the thick felted trailing leaves of the plectranthus.  I pinched the plectranthus, which is related to coleus, all summer long.  This made for an overall shape that was widely horizontal.  The tall grass, in contrast to the very wide plectranthus-a certain visual contrast that satisfied my eye.  The glimpse I still see of the pot at the bottom is just enough to complete the picture.  The planting does a good job of describing what the planter looks like, though you cannot see so much of it. This is a very simple planting which to my eye is very visually engaging.     

Big leaves-do you not love them? This severely contemporary v-shaped limestone  planter benefits from a planting of the paddle-leaved tropical plant dieffenbachia.  The pale yellow green leaves can dramatically lighten a very shady spot.  The yellow variegated ivy once established, I kept trimmed to the inside edge of the stone, as the container itself makes such a strong statement.  The overall shape of the planting seems pleasing to me.  This planting greatly complements the container.      

This planter located on a city street got planted with a lime green version of dawn redwood-a lime green version of Metasequoia.  Small trees can be great in containers; they can be planted in the ground at the end of the summer season.  The  fiber optic grass and Scotch moss are just about the same shade of green.  This planting is simply about texture, and plant habit.  The relationship of one plant to another is enough to keep me gardening.   

The lime green dracaena Jenny Craig is another great tropical plant suitable for containers in shady places. The strappy leaves cascade like water from a fountain.  The variegated licorice petticoat pictured above provides some width that helps to balance the composition.  The detail of the urns is still visible.  I spend a lot of time picking and choosing what of a container gets hidden by draping plants-and what stays exposed.   

This cardoon is a very architecturally striking plant.  The leaves have a prehistoric, slightly menacing look about them. They have an aura which is so strong-they have the visual power to organize a space. The blue green succulent planted at its base-I have no idea what this is called-sorry.  My eyes and my instincts just told me they would work in this container.  These succulents do a great job of softening the look of the cardoon-even though the foliage is stiff, and needle-like. The silver falls dichondra drapes down the corners of this lead container, and puddles on the ground-a languid, and gorgeous contrast to those stiff cardoon leaves.  In general, it is easier to achieve a balanced compostion with three elements, as opposed to two. A container with one or two elements will need thoughtful work on the shaping as it grows, to keep the arrangement visually interesting.  A single well cared for topiary plant in a pot would be a good example of this kind of grooming.  

The lime green flowering nicotiana alata is one of my favorite flowers.  Green flowers-not so ordinary, but eminently satisfying.  The tuft of verbena bonariensis at the top loosens up the entire planting.  The wide outer border planting of white million bells, green and white plectranthus, and Kent Beauty showy oregano, softens the top edge of the container, and balances the height of the nicotiana and verbena.    

These bronze containers are very intricate, and beautiful.  Given that they flank a front door, I plant them tall.  The King Tut papyrus provide great height.  The tall white zinnias read mostly green.  The lime sweet potato vine- they speak strongly to lush. A planting of white mini petunias add some froth where some width is needed.    


Any predominately green composition gets attention from me on lots of  levels.  I cannot really explain this-except to say that great color enchants, and distracts me.  No doubt beautiful color gets my attention.  But when I design, I imagine every element in black and white.  Composing containers in green and white is like looking at the natural world in black and white.  Black and white-this teaches me plenty.

Planting Great Containers


Every great pot starts with some rocking good science.  A container needs to be sized to comfortably hold the plants you want to grow when they are full grown. Rhubarb planted in a 10 inch pot-not a good look.  Nor is it a workable idea. Every container needs lots of drainage material; I usually plant large containers with 2/3 drainage material and 1/3 soil.  Very small containers I might fill to the top with soil, with a small piece of landscape fabric over the drain hole.  The ability to maintain even moisture is essential to the health of the plants.  Good soil holds water.  My soil mix is a custom blend of compost, topsoil and sand-I do not grow plants in soilless mixes.  Growers mix is designed for professional growers who require a weed, pest, and disease-free medium.  It takes a skilled hand to properly water and feed any plant grown in peat based plant mixes-every grower has their own formula. For a gardener, the best part about them is how easy the bags are to pick up and carry.  Ease of soil transport is not a factor in planting great containers.  I like to grow plants in soil.  real soil.  I like all the organisms, the micronutrients-I like living soil, not sterile plant mix.
The next issue-where will they go?  Pots flanking a formal front porch may ask for the same plants that you use on your terrace-but how you use those plants is about inspired design.  Great containers have everything to do with good design.  This traditionally styled two tiered wirework plant stand is a completely unexpected choice for a contemporary concrete deck/terrace featuring a stainless steel braided wire railing.  That juxtaposition of the round and delicate wirework with this minimal fencing is a visual surprise.  As for the planting, imagine this planter without its topknot of faux tulips and grass.  You get this-dull.  The additional height breaks the horizontal line of the fence-this makes for great rhythm.  The planting at the same height as the rail-static. The idea that stops short, comes up short. That tulip and grass hat-very sassy.  This single planter holds its own, in front of that somber forest of hundreds of tree trunks.  The big-faced pansies are in the larger bottom tier, and the diminuitive violas in the top; the size of flowers themselves should be proportional to the size of the container.  The restricted plant palette has a contemporary feeling; the mix of colors has a more personal feeling without getting too frou-frou.  I like this planter, how and where it is placed, and how it is planted, relative to this forest dominated landscape.    

Sometimes the shape of a planter will suggest how the plants should be used.  Pale yellow pansies in the center back, and bright yellow pansies on the edges highlight the color and form of the violas in the front.  Light colors do a great job of bringing dark colors placed in front of them to life.  The yellow twig dogwood placed in a row, rather than a bunch , celebrates the shape of the container.  The ivy at the corners-a yellow variegated variety that repeats the yellow of the flowers.  Plants that would thrive in this lighting situation go on to work together well.  This look-a thoughtful and put together look.

Pots in commercial settings need to read well from the street.  I would not want anyone passing my shop to not get a good look.   This can mean generous height, and compelling color.  Subtle works much better up close to the eye.  In this case, a bunch of yellow twig dogwood has been augmented with faux yellow flower stems made from bleached and dyed palm leaves.  Forsythia is common in my spring landscape; passing by in a car, this centerpiece is entirely believable.  More striking than real forsythia, this centerpiece will provide great scale and visual punch throughout the spring.  A pot of tulips in the center can be switched out for fresh when the flowers fade; annual phlox intensia and violas will grow and do well on into early summer.  The red violet, lavender and pale yellow tulip mix is from John Sheepers-they call it the Princely mix.  The color combination is really lovely.  Small pots for a tabletop ask for one thing, well grown.  Small pots have to be placed close to eye level to be appreciated, so  I plant small pots with plants that are easy to grow to perfection.  This pot of violas seems happy-no yellow leaves, no dead flower heads.  It looks good, up close.

In terms of container design, it does not matter whether you are planting a vintage bulb crate from the Netherlands, or a fine pair of antique urns-the container is as much a part of the planting as the plants themselves.  These tulips were planted low, so the lower foliage would not obscure the beautiful surface and vintage lettering on the crate.  The boxes on the roof of my shop-they were constructed of sheet metal, and reinforced on the inside with pressure treated limber.  They are a vehicle for the plants that make my summer roof garden.  These rectangular boxes hold soil, and support plant life.  They are not in any way beautiful.  They are serviceable.  Every space demands a little something different.  At my office front door-I want beautiful containers, well designed, and thoughtfully planted.  On the roof, I want to make but one point.  Anyone who looks at what is growing  on the roof-I want them to see that garden.  A beautiful garden.   

Planting in the ground- a second cousin twice removed from planting in containers.  Big spaces on the ground plane ask for a different approach than containers.  Soil and seasonal flowers, above ground, in containers, could not be more different than seasonal flowers planted into the ground.  More tomorrow-I promise.
