Time to Plant Fall Containers

Pennisetum with Heuchera ‘Caramel’, Cuphea and Calibrachoa

One of the pleasures of container gardening is that you can create fresh arrangements to complement each season?s landscape. The colors of Fall Chrysanthemums have been selected for just this effect, but isn?t it dull to limit yourself to just a single plant? Consider the wide selection of cool season “annuals” that are at their prime in September and October, offering at least 6-8 weeks of color. There are ornamental peppers, salvias, grasses, million bells, abutilons and cigar plants, just to name a few. Don’t forget the perennials with outstanding foliage, like Heuchera ‘Caramel’ and Autumn Fern (Dryopteris erythrosora)  which add contrast and can later be transplanted into the garden for next year?s display. And then there are shrubs with fall interest, such as Hydrangea paniculata ‘Little Lime’ (aging  blossoms), Cornus ‘Arctic Sun’ , and Ilex verticillata (Winterberry), which will add height and weight to bigger pots. Here are two more tips for pulling it all together.

First, remember to select a variety of bold and fine textures. The bold punch of a large leaved Heuchera, or Ornamental Cabbage adds much needed weight and contrast. This is the season of ripening fruit, so take advantage of the ever widening selection of Ornamental Peppers or consider shrubs with a nice berry set, such as Viburnum or Winterberry. Grasses add height and movement, and you can always use hardy grasses besides the more showy annual Pennisetum.

Second point: The growing season is slowing down here in the northeast, so start with larger plants and/or use more plants to fill up the container right away. There is not a lot of time now for plants to put on added growth. Think of assembling your container as you would a flower arrangement, except that this composition will last for weeks as opposed to just a few days.

Container Combo for Dry Shade

Begonia, Pilea and Tahitian Bridal Veil

Again, it is so much about the foliage. The angel wing leaves of Begonia ‘Sinbad’ are really a soft celadon green veined in rose, but have a silvery cast. On close inspection, the silvery effect is due to the pebbly texture formed by the tiny raised white leaf segments. Simple, sweet pink flowers dangle from the leaf axils.  For filler, the tiny white variegated foliage of little Pilea, commonly called artillery fern, creates a frothy effect beneath the bolder leaves of ‘Sinbad’ and the casual abandon of Gibasis geniculata , also known as Tahitian Bridal Veil, with its two tone green/purple foliage and white baby?s breath blossoms finish off the combination.

Culturally, use a well drained potting soil, amended with Osmocote. Begonias do not want to live in soggy soil, so monitor watering by allowing the soil to dry out a bit. This ensemble would enjoy morning or filtered light, and would be a suitable arrangement for a covered porch, where the minimal watering needs can be monitored.

Container Combinations III: New Ideas

Remember when Coleus was disdained by “serious gardeners” just 20 years ago? Until recently Succulents also seemed to get a bum rap. Perhaps it was because of the silly little dish gardens offered in discount stores, featuring a ubiquitous strawflower glued onto a poor little cactus. We decided quite some time ago to treat succulents with dignity. Their foliage offers an array of subtle and strong desert colors and textures which inspire us with ideas for endless combinations. And, they couldn’t be easier to take care of– perfect container plans for the summer weekend home, since so little water is required.

Begin your ensemble by selecting a handsome container. Break the rules…why not use a fancy bowl or urn that you would use for traditional annuals? Shallow pots are always fine and suitable, but deeper pots can certainly be used if you fill them with a very sandy, fast draining soil. Do not use a moisture retentive peaty potting mix, for it will easily become water logged if we have extended wet weather. You can use a light dose of fertilizer in your soil mix, but don’t over do it.

Select a variety of foliage shapes and plant forms, such as the rosettes of Echeveria, the trailing stems of Delosperma and the fine texture of tiny Sedum. We always find that packing the container with plants gives immediate gratification, and the plants will not suffer as they require little nutrition. Early autumn will bring changes to your composition, as the fall foliage colors intensify and many succulents begin to flower. Before a freeze, bring your succulents indoors. They winter over easily on a sunny window sill.

Red Combo for Part Shade

Red Combo for Part ShadeThis easy care combination, which will be very happy in a spot that receives 4-6 hours of sun, includes Fuchsia ‘Gartenmeister’ complimented by multihued Calibrachoa ‘Tequila Sunrise’, Helichrysum ‘Limelight’ for light contrast, and Coleus ‘Dipt in Wine’ which picks up the colors of the other 3 candidates.

The Fuchsia and Calibrachoa (Million Bells) will lure hummingbirds and bloom endlessly. Should the Helichrysum (Licorice Plant) or Calibrachoa exceed their bounds with vigorous growth, just clip back. Plant this grouping in a good quality potting mix amended with compost or PlantTone, and Osmocote. In addition to fertilizer in the mix, we always recommend liquid feeding your containers every 1-2 weeks with a balanced plant food, such as Dyna Gro.

Container Combinations I

Pink/Wine/Silver Combo

A classic combination for a sunny spot. We’ve combined our favorite Pelargonium sidoides with a new heat tolerant pale pink Marguerite, Argyranthemum ‘Pink Reflection’, silvery Centaurea gymnocarpa ‘Colchester White’ and Dichondra ‘Silver Falls’ and a compact selection of Gaura ‘Belize, with wine tinted foliage and wine/pink blossoms that dance on 18-24″ stems all summer.

Planting Containers

Focus on foliage

Container Gardening is a summer long activity. Plants grow quickly, and it is only a matter of week or two before a new grouping “knits” together. You can move, mix and match pots all season long.

We’d like to pass on basic tips for successful container plantings.

1. Select plants that all like similar growing conditions (i.e…sun, shade, dry soil, moist soil).

2. Use a good quality potting soil amended with an organic plant food like Garden Tone and/or Osmocote time release fertilizer. 

3. Remember to select/focus on plants with interesting foliage, which will add color and texture without the need of constant flower deadheading. Think of the flowering plant choices as the “accents”.

4. Finally, liquid feed with Dyna Grow or Seaweed/Fish Emulsion on a regular basis, which will replace the nutrients leached out of your pots from frequent watering.
