Recent Work

We have been planting container projects daily, one after another, since May 15. With time outs for cold, and torrential rain. I do not ever remember a season quite like this one.  Very cold night temperatures, cloudy skies and relentless rains have been the order of the day.  A client remarked that we have had rain for 65 days of our last 90. That is an astonishing statistic. It has meant constant interruptions to our work schedule. Cold nights have meant we are hesitant to put temperature sensitive tropical outdoors. The gray skies mean plants have been slow to come on in the greenhouse.

I explained the situation to one client as a discussion about what constitutes providing a good home for a plant. A home is a warm, friendly and inviting place. Home for tropical plants far away from their native home means we wait for weather and soil temperature that approximates the conditions under which they thrive. Many of my clients for whom I plant begonias, coleus and New Guinea impatiens have had to wait. Who doesn’t hate to wait?   My suggestion is that their plants are thriving and growing in storage in a greenhouse.  Planted out in their pots in cold weather, they would languish. The temperature this morning June 11 at 5am, 48 degrees.

The cold has not been the only issue. Rain is essential to plant life. I doubt I need discuss that with any of you. Rainy weather working its foggy magic on a landscape is beautiful. A rainy day encourages introspection. Or at the very least a nap. I love the rain in all of its spirited and benign forms. But we have had rain day after day without much respite. This is rain of a different sort. Too much rain foments rot both above and below ground. Too much rain spoils blooms. Too much rain dampens the spirit. We have had all of the aforementioned. The most dramatic signs of distress have come from the mandevilleas. These vining plants like hot weather and dry conditions. They look beautiful in the greenhouse, and poor to middling outdoors. It is tough for plants to settle in and thrive when their medium is watery. And more watery.

All of our rainy days have been attended by clouds. Naturally. Growth in annual plants is directly related to sunny circumstances. This means we have been planting smaller plants than usual, in those moments between the rains, in the cold. Am I worried?  Not so much. Warmer and drier weather will come our way sooner or later. All of those container plantings will need some time to grow before the design and intent is clear. I have time for that, in my more rational moments. The day a container is planted is its first day –  not its best day. The best days are months ahead.

Postponing a planting can be the best strategy when conditions are hostile. This year’s conditions are obviously hostile. But in general, I do most of this planting in late May and June. May is a spring month in my zone. What looks good are the spring flowering bulbs, the wildflowers, and those shrubs and trees that thrive and bloom in cooler weather. The Venus dogwoods are glorious right now.  The geraniums, not so much.

One way to deal with lost time is to plant larger plants.  6″ pots instead of 4″. Hanging baskets in lieu of 6″ or 8″ pots. Growing summer blooming annuals from seed or cuttings is a lengthy process.  That is why growers have greenhouses, and grow under glass.  Many of the most cutting edge of those houses have very sophisticated lighting and watering devices. If warm weather, reasonable water and sun were not necessary to grow on tropical plants, growers would grow outdoors. That said, every greenhouse where I shop has run out of or are low on plant materials that I customarily use all the way through June.

We have a solid 2 weeks of planting still to go. Just like the weather, we are just getting warmed up.

I would not want to do without container plantings, whatever the weather.

 

The Summer Container Plantings

The demand for landscape design and installation has been one after the other this spring.  I am sure you can tell, given how few and far between my posts have been of late. Our persistently chilly weather has given way to some gardening friendly weather. Suddenly, the summer container planting season is here, and my board is chock full of projects that will need doing beautifully, and with dispatch. The summer plantings begin later in May, and finish up in late June.  Late June? The spring plantings are just beginning to come in to their own now. Clients with spring plantings are not in a rush to plant seasonal tropicals. Given that tropical plants dislike cold temperatures, and hate cold soil, a spring planting can stave off that urge to plant summer containers too early.
Of special interest to me is the unique role played by containers in the landscape. No news here,should you be familiar with Detroit Garden Works. For 23 years now, the shop has been a premier source for great ornament for the garden.  I am happy to say that our reputation in recent years has become a a national phenomenon. Jackie deals with clients all over the country, and manages a steady stream of shipments going out. The shop website is good, and easy to navigate. Jenny keeps it fresh and lively.

Of course the lion’s share of our focus is on containers of every conceivable period and style. Vintage dolly tubs and new locust wood casks belted with galvanized steel rub elbows with a select collection of European and American antique urns. Of course the choice of a container is a significant factor in container planting. It is as much an important part of the container arrangement as the plants. That empty container represents the opportunity to throw a party in celebration of summer. The limited square footage imposed by the edges of a container means the design idea has to be simple. And it has to be visually strong.The plants need to be companionable, or at least tolerant of one another. Container plantings at war with nature make me uneasy. Given the almost limitless number of plants that can thrive in a container, it would take several gardening lifetimes to even make a dent in all of the possibilities.

A container planting matures in but a few months. What a pleasure to be able to watch that process. Mercifully, it all comes to an end with a hard frost. One can abandon a scheme that disappointed. Or explore a new idea come the new season. A collection of containers is a visual diary of what is on a gardener’s mind at that moment. A landscape and garden involves a long term commitment. There is strategy and planning involved. Decisions that are made one year are not so easy to change years later. An old tree that succumbs to an illness or bugs can make for chaos in the garden below. Growing a landscape on can feel like a full time job. The blooming of the double bloodroot, dogwoods, lilacs and peonies are ephemeral, but the gardener gets to enjoy them year after year, barring a disaster. A collection of containers set within that landscape keeps the garden dialogue fresh and interesting.

Containers do not need to be large to be good. I still like this planting, 10 years after the fact. I like the color of the gold marjoram complements the color of the glaze. The lavender star trailing verbena is a lively contrast to the yellow petunias.  The overall shape is relaxed, and proportional to the container.  Small containers ask for small growing plants.

Hot sunny places are the perfect location for seasonal plants. The profuse bloom on these petunias and mandevillea speaks to those conditions. Seasonal tropical plants are a way to have flowers every day all season long. The plastic liner in this wicker basket helps to keep the wicker from deteriorating from constant exposure to moisture. And that plastic means a basket this size will not require watering every day in the heat of the summer.

Double white petunias are leggy, and those legs are not so attractive. Pairing them with euphorbia Diamond Frost disguises that unfortunate trait, and holds up those heavy double flower heads. The datura  provides a contrasting texture both in leaf and flower.

This wooden trough features a large collection of different plants, all arranged in a very informal way.  Insouciant in feeling, this.

Any container planting can be endowed with a contemporary feeling-the design plays a major role in that.

Lush and lavish by summer’s end speaks to months of consistent maintenance. For those whose life means picking up a hose comes last, an irrigation contractor can install watering lines that can buy you some time. If the need for low maintenance is a deterrent to planting, many tropical plants don’t need dead heading, staking or frequent water. A clear understanding of what kind of gardener you are can inform the plant selection process. The big idea is to enjoy the process as much as the results.

 

I planted trees, shrubs and perennials in my own pots last year. I was surprised at how much I enjoyed that. What will I do this year? I do not have a clue, yet.

The 2019 Tulips

A few days ago I drove to Metamora to see a client. For those of you not in my area, it took over an hour and a half to make the trip out and back. I only saw tulips blooming in one place that entire trip.  A group of 30 or so bright peach tulips outside a business were easy to spot, even though I was driving 55mph. They looked glorious.  Nearer to my client’s property, miles on a country gravel roads, I saw nary a one. How disappointing, given that we are coming up on peak tulip season. There are so many species and groups from which to choose. A smattering of every class of tulip could keep a gardener in tulips for 6 weeks or better. But planting tulips has been in decline in our area for quite some time.

I am sympathetic to gardeners who are having to deal with exploding populations of deer. They are incredibly destructive to landscapes and gardens alike. They can mow down an emerging collection of tulips in no time at all. Once the flower bud has been eaten off, that is it. No secondary bloom stalk and bud will replace the first. To see them destroyed is frustrating. It will be a year before there is an opportunity for a second chance.  I would guess that declining tulip planting is in direct proportion to increasing deer populations. We have them at the shop, even though we are in an urban area. The vacant field next door is hardly what I would call a friendly habitat for deer.

We do drench the young tulips from the time they break ground with Deer Scram or Liquid Fence.  We have a number of deer repellent sprays, and we alternate them. We also fortify the perimeter of the bed with Plant Skydd. I find that deer repellents work, as long as we are possessed with applying it often and consistently. Of course this is a nuisance and an expense – but less so than the prospect of no tulips. Every tulip that came up is either in bloom, or about to bloom.

The first year following a fall planting of tulips is always the best. We plant number one grade bulbs that have been patiently grown on to that size by growers in Holland. A number one grade bulb results in a number one grade flower. A tulip bulb will divide itself after the first year. A smaller grade bulb produces smaller flowers, and in many cases, no flowers at all. So yes, a planting of tulips is not a forever planting, unless you limit your choice to the early flowering species tulips that are known for their persistence. If you should decide to defy nature, and provide optimum conditions for a repeat bloom the following spring, the foliage must be left intact until it completely matures. This can take a month or more. The process of photosynthesis enables the bulb to store food for next year’s flowers.

The length of flowering has everything to do with the weather. A warm spring means a brief flowering period. A long cool spring means the flowers will last longer. This is true for every spring flowering bulb or ephemeral. Unlike the crocus, or the double bloodroot, who have been known to bloom and drop their petals over the course of one day, there will be that moment when the tulip flowers are perfectly glorious. That moment of great beauty is not much different in duration than the lilacs, peonies, redbuds, dogwoods and magnolias-brief, but so sweet.

Tulips come in a wide range of colors.  Just about every color, with the exception of blue. Gardeners in my zone who value blue is the spring have to content themselves with forget me nots, brunnera, lobelia, nigella and delphinium, among others. Choosing a collection of colors and succession of bloom can be a lengthy process, as there are so many possibilities. The flowers are large and striking, to say the least. This means they may not play well with other plants whose flowers are not so large or spectacularly showy. They can be tiresome in their demand for attention. In much the same way as peonies, delphiniums, lilies, hibiscus-you get the drift.

I have tried to dispassionately cover all of the reasons why not to plant tulips, but I would not dream of not having them myself. From the time they emerge from the newly thawed soil to the bloom a month later, their rapid growth is an enchanting process to watch. The leaves are beautiful in volume and form. Newly opened tulip flowers grow larger with every passing day. They brave the wind, cold temperatures and the occasional spring snow with aplomb. Even the tallest varieties stand upright without assistance. They make terrific and long lasting cut flowers, given a cool spot indoors. The variations in flower and leaf form, height, color and bloom time make them one of the most versatile of all spring flowering plants.

I plant a collection of tulips at the shop every year. This moment has been many months in coming, and is so welcome after a long drab winter.  A lot of pictures get taken. Parents photograph their children with them in the background, and friends who come to shop do the same. I never see anyone walk by them without taking a good look.

The bloom is just about at it peak moment, should you be inclined to take a look. As for the trouble it takes to get to this moment, none of that interferes with the experience. Did I mention that fresh spring fragrance?

stunning, this.

 

 

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.
