Last Days to Sign Up for Gardening Summer Intensives, Classes Start July 16

As a former Broadway performer, professional garden photographer, and writer, Ellen Zachos is a very talented NYBG instructor whose container gardening class comes alive with gorgeous slides and dynamic presentations.

Ellen’s career as a gardener began when she got her very first plant–rather than a bouquet–as an opening-night gift, after performing in a Florida dinner theater production of Fiddler on the Roof.

“It was a Spathyphyllum, an ordinary peace lily,” she says, “but to me it was wonderful. I was intrigued, and I had never grown anything. My desire for knowledge just took over. My apartment filled with houseplants and books.”  

She went on to study Commercial Horticulture and Ethnobotany at NYBG. After receiving her certifications, she authored several gardening books and founded Acme Plant Stuff in 1997, a company that designs, installs, and maintains both interior and exterior gardens.

Mums and Japanese Anemones in Fall Flowers of Japan

We are celebrating the fall this year with Fall Flowers of Japan in the Enid A. Haupt Conservatory. As you walk into the Conservatory  you are greeted by color, ranging from the blues and purples of gentians, to the autumnal bronzes, yellows, and reds of chrysanthemums.

Texture and form abound; the orchid-like flowers of toad lilies (Tricyrtis) are speckled, Japanese anemones (Anemone) feature cup-shaped flowers and fuzzy seed heads, and Japanese burnet (Sanguisorba) provide height with their burgundy bottle brush spires.

For the opening weekend I conducted a demonstration on how to recreate a little piece of Fall Flowers of Japan at home in the form of a fall container display or border. Today I am going to share some of my favorite plants for making a display of this nature with you.

See Sonia’s picks for creating your own Fall Flowers of Japan at home below.

By now your garden should be ablaze with color. If it’s not, and you’re finding that you have unsightly gaps in your border, don’t panic! There is still plenty of time for an easy fix: Add a container display to your garden! Don’t limit your container plantings only to the patio though, containers are also a great way to jazz-up any dull or quiet beds or borders you might have.

An attractive container display starts with a good foundation–a good looking container. Many containers these days are made of synthetic materials like poly resin and fiberglass. These materials are often transformed into believable reproductions of classic containers. Find one that suits your gardening style.

If you are in the market for a rustic looking container try wood, faux wood or faux stone. If you prefer a more elegant look, then invest in terra cotta, faux terra cotta, reconstituted stone, or faux cast iron. Artistic souls will welcome the stunning array of colorful glazed pots as well as colorful lightweight synthetic substitutes that seem to be available everywhere these days. A few years ago I fell madly in love with a fiberglass reproduction of a bronze container that looked durable as well as lavish.

Maintaining appropriate moisture levels can be a challenge when gardening in containers, particularly if you like to escape for a few days during the summer. As common sense would dictate, the larger the container, the easier it is to keep it well-watered. There are many self-watering containers or contraptions on the market that you can outfit your container with. They are essentially water reservoirs that hold the water in the bottom of the container and slowly release it into the mix.

Another viable option is to add some of water retaining polymers or hydrogels to your potting mix. These polymers grab water from the soil, expand as they hydrate, hold onto the moisture, and then release it when the surrounding potting medium starts to dry. Friends of mine who plant narrow window boxes swear by them. Two brands that are easy to find are Terra Sorb® and Soil Moist™.

Whether you are placing your container in the garden or on your patio it is always advisable to raise it up onto bricks, blocks or feet to allow for good drainage. Next week we will take a look at some candidates for filling your lovely new containers.

P.S. – Thanks to Pauline, Devin, and Shawn who answered our call on Twitter for photos of their real-world container plantings! Want to have a chance at seeing your garden featured in future blog posts here on Plant Talk? Be sure to follow us on Twitter or “like” us on Facebook!

It’s still early yet, but time to start thinking about what we are going to plant in our containers this year. The catalogs have been out now for a while and we have had our chance to peruse what is new and exciting in the horticultural world.

The new options this year are a lot of fun and they are not shy. Ball Horticultural Company has come out with a series of three velvety black petunias that will knock your socks off – and yes – black means black.

Petunia ‘Black Velvet’ is the pure black petunia that is a soft and sensuous as it name suggests. ‘Phantom’ and ‘Pinstripe’ are two variations on the theme. The former has a bright yellow star pattern that is offset by the black background while the latter has the same pattern in a smaller muted cream and bleeding pink color.

The grower reminds us the ‘everything goes with black’ – and it should. These are three very adaptable container companions. They have a nice compact mounding habit – 8-12 inches in height and spread. They should be widely available this year. Burpee is selling the all black petunia under the name ‘Black Cat’.

If black is the color of the year – you might also be interested in Calibrachoa Superbells ‘Blackberry Punch’. The flowers are magenta but the large throat on this plant is velvet black. ‘Blackberry Punch’ is a trailer that grows 12 inches high and wide yet will spill over your container and trail up to 36 inches.    read more »

Last week we looked dwarf conifers as container plants. Single containers – particularly with a small to medium sized tree or shrub can happily fill a corner on a patio. Sometimes, however, they look a little lonely, particularly if they don’t have enough pizzazz or weight to hold up on their own.

Many container plants look better when clustered in groups to form miniature landscapes. There is great latitude in how a homeowner can approach this task. The containers could all be the same giving a uniform look or you could go for a more eclectic arrangement of colorful and expressive pots. One way will give a formal feel to the arrangement while the other will give it an ‘arts and crafts’ feel.

You likewise have endless possibilities with your plant choices. Are you trying to create the feel of a miniature woodland on your patio, replicate a foundation planting or have a foray into a mixed perennial garden? It is important to have a vision of what you would like to create before you start selecting your container plants. read more »

Anything Goes—and Grows—in Potting Up Vegetables for Small Spaces

Francisca Coelho is the Vivian and Edward Merrin Associate Vice President for Glasshouses and Exhibitions.

You may not be aware of this, but every plant you have grown in a pot, box, can, tub, or other vessel is an example of container gardening. Your potted houseplants, summer pots of annuals, and hanging baskets all represent gardening in containers. In the tropics where I grew up, people lined their front steps with many colorful, painted containers of every shape and size. They filled them with beautiful, tropical, flowering exotics and with plants used for food and medicine. Versatility is the hallmark of the container gardener!

In front of the Enid A. Haupt Conservatory, as part of The Edible Garden, I am growing an assortment of tasty vegetables in containers. The design is simple-a mix of semicircles and straight lines with pots ranging in size from 14 to 36 inches in diameter.

The steps leading up to the elevated area are lined with pots filled with Tumbling Tom tomatoes, mammoth red cabbages, purple kohlrabi and kale, ornamental trailing sweet potato vines, and marigolds, included to ward off unwelcomed pests and to encourage hungry bees to pollinate my edible delights. read more »

Chef Keith Snow Grows His Own; Shares Secrets, Tips

Keith Snow is a TV host, cookbook author, and creator of Harvest Eating.com; he will present cooking demonstrations at The Edible Garden on July 11.

Many Americans want to take part in the harvest revolution and eat foods grown at home to ensure freshness, good taste, and reasonable cost. But what if you live in an apartment building—are you out of luck? Actually, no. Many people who live in urban areas around the country are taking part in the local food craze by growing food in containers.

Before you run out to the nursery to get started, consider whether your balcony or rooftop can handle the weight and whether your building permits it: A large container of wet soil can weigh 50–100 pounds or more. Multiply that by the number of containers you’d like, and check whether your site can handle the extra load. (If regulations do not allow for you to grow outdoors, you can certainly grow herbs indoors near a sunny window.)

Once you’ve resolved where to place your plants, you’ll need to decide what to grow. Some plants are perfectly suited to containers, others are not. I like to advise people to create a kitchen garden in containers that can produce herbs, lettuces, tomatoes, cucumbers, eggplant, and peppers. These crops can thrive in containers and provide a lot of food and recipe diversity.
