April 2, 2019

What was noteworthy about this past Tuesday, the second of April? We planted containers and flower beds at 5095 for spring, 3 weeks earlier than last year. Our first spring planting. The morning was decidedly chilly, but the afternoon was sunny and warm. I could not have been more pleased or content to be outside planting. It was great. Nor could I have been more happy that we could be outside working the beginning of April. Northern zone gardeners are stuck inside longing for another time and place- for the duration of the winter. By the end of March, I am impatient for the winter season to turn to spring. And grumpy every day that it doesn’t.

The beginning of April is not always the beginning of our spring. Last year’s April was wintry in every regard. Mountains of snow deposited over the winter had no impetus to melt. The daytime temperatures were barely above freezing. The nights were plenty cold. The weather was conducive only to ice making. Giant piles of snow transformed by freeze and thaw into ice were everywhere. We planted this project April 22 last year. Embarrassingly late, that.

That I was outdoors on a sunny day with no more than a spring jacket to keep me warm was a good day indeed. I have more to be thankful for than this. My supplier of twigs sent an outstanding collection of fresh cut branches to us. That he farms willow and pussy willow provides great scale to my spring containers. Our pansies are fall sown, and over wintered in unheated greenhouses, so they are good to go outside the moment I take delivery. A whole collection of visually persuasive faux grasses-I thank Rob for them. They provide an intermediary layer between what is tall and what is short. These pots would be rather awkward without them.

A sunny warm April day, some spring centerpieces of note, and a raft of thriving pansies is enough for this early spring day. I went home both happy and satisfied. Nothing in my garden has made itself known.  Later spring will be a symphony. At home, and on the job. So many voices – so much to see. Spring in full blast is hard to keep track of. But this earliest moment, out planting, was the gift of the early season.

This bed full of a pansy mix will sparkle all season.  Lavender shades, Delta Premium violet and white, and pansy beaconsfield mixed will shimmer. If you plan to mix varieties, 3 types provide a more even mix than 2.

This bed of pansies will thrive well into June, should my client decide to delay her summer planting. She might be tempted this year to let this spring planting mature. I for one would be much happier planting her containers for summer in June. Both the soil and the air will have warmed up by then – just what seasonal tropical plants want.

Cool Wave Berries N Cream is a spreading/trailing pansy.  It is perfect for those container plantings that ask for flowers spilling over the edge. This pansy is reputed to survive our winters with aplomb, should you decide to plant it in the ground. This urn was planted with hanging baskets of this pansy. The more mature size of the plants in the basket provide height and volume right from the start.

There are few signs of the perennial garden in this area. These spring pots provide some visual interest, in the meantime. Containers in every season can be a bridge from one garden moment to another, a landscape or garden idea tested in miniature, a laboratory for testing new plants – I do value what containers can bring to the garden.

This long trough is my favorite of the group. The columnar lemon cypress will go on to ornament both the summer and fall planting here. Pots of Persian limes between the cypress will do the same. Yellow and violet pansies compliment the spring green. The summer green will be just as luscious.

Four large planters in the back yard are routinely planted with multi-trunked Himalayan white barked birch. We take them out of the pots in the fall, and winter them inside our landscape building. Very few woody plants are hardy over the winter in pots. With their roots above ground, they struggle to handle the extreme cold of our winters, and unexpected freeze and thaw cycles. Even though our building is unheated, it provides protection from winter wind and sun. As all of the leaves drop in the fall, they have no need for light in the winter months. The birch provide much needed scale to a rear terrace that is large, and a pair of doors from the inside that are very tall.

This is the first year I have under planted the birch for spring. On the terrace-flats of pansies and violas. The mix is lively, as I hoped it would be. Anyone who plants containers brings an idea about shape, mass, texture and color to their plantings. In this early spring container planting, color is a key element.

Mixing plants implies a brew. I like this. Who knows what nature is brewing up next, but for now this spring brew tastes great.

It was a good day.

Planting Spring Pots

My penchant for planting containers for spring is based on several factors. At 30 years old, it seemed like an infinite number of springs were ahead. If I skipped planting fall bulbs, or spring pots, or a rose or a tree, there would always be next year. Or the year after that. In a blink of an eye, 30 became 50.  And with it, the dawn of the realization that though spring will probably roll around ad infinitum, my springs that had a beginning in 1950 would eventually come to an end. This is not gloomy talk. It means I am more interested than ever in observing and participating in every phase of the gardening year. I especially do not want to miss one moment of the spring season. Given that every plant in the landscape will break dormancy and grow, there is a lot to see over the course of that 3 month period. There are lots of ways to experience the spring season-why miss out on any of those opportunities?

Planting containers for spring seems even more attractive in cold weather zones like ours. Winter leaches out of our ground slowly. When that ground does thaw, it is wet. Milling around a garden when the soil is sopping wet is ill advised. My shoes, backed up by my weight, do a great job of squeezing the oxygen out of the soil, and compacting it. Compacted soil can be quite brick-like. As I like my plants to have friable soil that encourages good root growth, I stay out of the garden in very early spring. Spring containers make it easier to resist getting in to the garden too early.

It used to be that a vast majority of seasonal plants were of the summer season type. Now a gardener can find plants suitable for containers in every season. The most obvious choice is spring flowers bulbs.  Forced tulips, daffodils,hyacinths, grape hyacinths and crocus adapt very well to pot culture. The tulips in the shop garden are but 2 inches out of the ground. It will be at least a month before they start to bloom. A pot of emerging tulips faced down with violas already in bloom in a container is a sight for winter weary eyes. The best part of spring flowering bulbs in containers is how beautiful they are in every stage. It is a pleasure to be able to watch a hyacinth at close quarters come out of the ground, bud up, and bloom. The leaves and buds are juicy, and every bit as beautiful as the flowers.

It used to be that most seasonal plants offered for sale were only suitable for summer containers. That has really changed. Great plants, and lots of them, are available for container planting in every season. Right now at the shop, Rob has hellebores, pansies, violas, alyssum, primrose, rosemary and lavender topiaries, sweet woodruff, and sweet peas.  In short order, spring vegetables and herbs will be available for pots. Pansies, lettuce and parsley can be planted up to stunning effect. A hydrangea on standard can look a little bleak in a spring container, but the buds will swell soon, and the spring leaves are beautiful.

Fresh cut twigs can provide a lot of color and scale to spring containers. This straight copper willow not only has vivid color, that color is lively.

Pussy willow is a great twig choice for pots.  The fuzzy catkins covering the stems are charming.  Cut pussy willow twigs will often root in a spring pot, bringing leaves after the catkins have faded. Pussy willow would be a poor choice of a shrub for my garden, as it grows so large. Having the cut stems in a container is a way to enjoy them without making any commitment to a long term relationship. And speaking of long term relationships, it is a pleasure to have the opportunity to try something new in containers every spring.

We will be starting our installations of spring pots this coming Monday. It will feel good to be gardening.

The Finish

All that work early last week in preparation for the installation of a group of pots planted for fall came to the following. I hope you enjoy them.

Our fall container season will pick up steam from this point on, as will the fall landscape and garden. Looking forward to it.

The Summer Containers

By no means have I had a chance to go back and look at all of the container projects we planted in late May and June, but I have had a chance to see a few.  The season so far has been very friendly to the tropical plants. I am referring to the heat, of course.  Any gardener that has been able to keep up with the daunting task of watering their containers properly has been rewarded with an astonishing display of lush growth and lavish flowering. Proper watering is not constant watering. It means watering ahead of that moment when the plants stress from lack of water. A consistent and measured watering hand makes for great looking summer containers.People ask me what my protocol and procedure is for watering all the time. My best advice is to never assume a plant needs water. Assess whether it needs water first. The roots of plants that get too much water will rot, and will not be able to absorb water no matter how much is available. Keeping plants on the slightly moist side encourages root growth. That said, every plant has preferences about what level of moisture they require.  Planting containers with plants of a similar inclination makes a watering routine easier. The box pictured above is watered by hand. The boxwood and hosta had substantial root balls before they were planted into the container. Add a bright shade location to the mix, and you have a container that does not require a daily drenching to prosper.

The mandevillea this year are blooming profusely. They love the heat. In Michigan, they thrive in full sun.They also like just the right combination of regular water and good drainage. A mandevillea sporting yellow leaves is either getting too much, or too little water. You will not be able to figure out which until you try more or less water, and see if the trouble stops. This container is mechanically watered via a dedicated container zone on the irrigation system. Figuring out how often to water, and for how many minutes each time is a trial and error process. It is simple to tell by looking at these plants that the amount of water they are getting is just right.

The window boxes pictured above and below also have a mechanical watering system, but I happen to know my client does not rely on it.  His irrigation buys him some time, if he is busy and can’t get to the watering immediately. He checks them routinely.The exposure here is easterly, so the boxes are shaded from the sun in the afternoon. All these plants like the heat, and a reliable source of water.

The ability to look after plants does not come standard issue. It takes patience, observation, and experience to figure out what way works for both the gardener and their garden. Fortunately, a lot of ways work. Plants can be incredibly forgiving of mistakes, but over the course of a summer season, their water needs are not negotiable. It doesn’t hurt to site pots and pick plants with some thought to how they will be maintained. I am pleased with how our summer plantings are getting along.

My pots at home are doing fine. Karen, David and Marzela give me a hand with the watering on occasion. I have 43 containers. 20 boxes and pots in the front now have their own automatic watering zone. The two pots by the front door are hand watered – that much I can do. The remaining pots are all watered by hand. They were all soaked on Friday. Today’s a day I will need to check to see if they need water, or restraint.
