Late Season Plants for Pollinators

As gardeners, it is important for us to be able to enjoy our gardens as long as possible into the colder months! As allies and companions to our beloved pollinators, it is part of our task to help provide food sources to help them prepare for the winter months as well. 

Annuals

  • Zinnias are a long-season pollinator plant that will continue to perform into the fall. You may even see them returning to garden centers to be included in fall containers. 
  • Other late season bloomers like Tithonia, Lantana, Marigolds, Sunflowers  and Cosmos are particularly important food sources for migrating butterflies and other insects. Hummingbirds are very fond of lanatana nectar, so they will benefit as they migrate through in September.   

 

The Fall Garden is Still Great for Pollinators

Perennials

  • Goldenrod in full bloomNative goldenrods (Solidago spp.) provide nectar and pollen for diverse species of insects and seeds for birds and small mammals. Different species bloom from August- late September or even into October, when other native plants are past bloom time. They are important sources of energy for migrating butterflies and for bees that are active late in the season.
  • Other late season pollinator plants include Echinacea, Rudbeckia, Sedum and Asters

Late Season Cucurbit Harvesting

    Watermelons

    Watermelons  take 35-45 days to  mature after flowering, but temperatures and variety will affect time to harvest To determine if a watermelon is ripe, use these signs:

    • There is a curling tendril closest to the melon- this should turn brown and dry out
    • Carefully turn melon over to see f the white blotch where soil contact was made is now yellow
    •  Rind should be dull, not shiny
    •  Thump the melon- sound should be hollow-sounding, deep and resonant. Unripe melons will have a higher pitched flatter sound
    •  Check the days to maturity as given on the seed packet. If it says 65 days, then it should be ripe at that time, but check above signs, too. If you do not know the variety, then use 1-4 as a reference.

    Pumpkins/Gourds

    This time of year is when pumpkins will start reaching maturity. Harvest will be here before you know it! Keep these things in mind while deciding "is it time?"

    • Skin should be thick and pumpkins should be firm
    • Leave the stem intact to ensure a longer shelf life
    • Never lift or carry a pumpkin by the stem
    • Read More Tips

    Winter Squash

    Winter squash have many of the same harvest characteristics as pumpkins and gourds. 

    • Similar to pumpkins, the skin should be hard and difficult to puncture with a fingernail
    • Leaving 3-4 inches of stem attached helps preserve the fruit

          September Gardening Tips

                • September is a great time to have your soil tested. Beat the spring rush and have your soil ready to go well before the growing season begins!
                • Early fall is a good time to plant trees and shrubs and allows time for the root systems to get established before the ground freezes.
                • Visit a local nursery or garden center and select spring flowering bulbs to add to your gardens. Plant the bulbs among perennials, under trees and shrubs, or in larger groups for a splendid spring show. Choose colors that complement other spring flowering plants as well as nearby plantings. Work a little Bulb Booster or 5-10-10 into the bottom of the planting holes.
                • Continue to water any new shrub or tree plantings until the first hard frost.
                • Do not fertilize trees, shrubs and perennials in late summer. Doing so may cause new growth that will not harden off before winter.
                • Use a mulching blade to finely chop fallen leaves of healthy trees and let them decompose on the lawn. Completely remove and dispose of any leaves that have shown signs of disease.
                • Move the houseplants to their indoor locations before the furnace gets turned on so they can start becoming used to the lower indoor light and humidity levels.
                • Pot up or propagate herbs to bring indoors for winter use.
                • Watch for frost warnings and cover tender plants.
                • Do not add diseased leaves or stems into the compost pile. Temperatures of home compost do not usually get high enough to kill pathogens and can cause disease to reoccur in your garden next year. 
                • Do not add weeds with mature seed heads to the compost pile. Many weed seeds can remain viable and germinate next year when the compost is used.

                Tips from UConn Floriculture Help Spruce Up Container Plantings

                By Dawn Pettinelli, UConn Home & Garden Education Center

                As summer wanes and the cool breezes of autumn begin to roll into Connecticut, it’s the perfect time to refresh your container plantings. Shelley Durocher-Nesta, UConn Plant Science Floriculture Grower, says this summer’s rain and high temperatures have many of our container plantings looking a little ragged but fall presents a unique opportunity to infuse your outdoor spaces with rich colors, interesting textures, and seasonal charm that lasts well into the cooler months

                By the end of summer, many annuals start to fade. To maintain a lush and lively look, she suggests replacing them with plants that thrive in cooler weather. A top candidate for fall plantings, both containerized and inground are mums, obviously. They offer an explosion of color in shades of yellow, bronze, pink and reds. Asters are runner’s up, flashing their cooler shades of purples and pinks.

                Ornamental cabbages and kale are leafy plants bringing texture and interest to plantings, often with their lacy ruffled edges. Hues range from deep purple to violet and from white to green, some being two-toned.

                Recently, pansies and violas have been showing up as fall bloomers. These delicate flowers add a pop of color and laugh off light frosts. Pansies, with their cheerful ‘faces’ are particularly popular and come in a wide range of colors. Ornamental peppers in shades of yellow, purple red and orange are also available often in 4-inch pots

                Depending on your color scheme and container size, two other great fall accompaniments are heuchera (coral bells) with their stunning foliage in a myriad of colors, and sedums that can be used either for their unique fleshy foliage or pollinator-friendly blooms.

                Don’t forget ornamental grasses for their attractive seedheads and whispering foliage. If pinched for room, a few stalks of dried grasses or wheat can give your containers a rustic, harvest-time feel.

                Before purchasing new plants, access the plants presently in your containers. Groom, deadhead and cut back leggy annuals like petunias and verbena. If you have summer plants that are still thriving, you can repurpose them by combining them with fall plants in the same container for a mixed-season look. However, often one finds that their summer layout doesn’t work as well with new plants. Don’t hesitate to replace staid offerings. Durocher-Nesta, agrees saying that switching out her summer planters that are getting a little tired by the end of August is a joy.

                Refresh the soil in containers before planting new fall selections. Summer plants have depleted the nutrients, so replacing the top few inches with fresh potting mix can get fall plants off to a better start. If your container is large and you can’t replace all the soil, mix in some compost or at least a slow-release fertilizer, as directed on the package, to rejuvenate it,

                Consider elevating some containers on stands or steps to create varying heights. Grouping containers of different sizes together on your porch or patio can also add depth and visual interest.

                One of the joys of fall container gardening is the chance to play with a different color palette. While summer is about bright, vibrant colors, fall offers a more subdued, warm earthy palette. Think deep purples, burnt oranges, and rich reds, balanced with greens and whites.

                As the weather cools, plants will need less water but check regularly. Container plants can dry out quickly especially on sunny fall days. Stick a finger in and add water when the top inch of potting media feels dry.

                Regularly deadhead spent flowers and remove any yellowing leaves to keep your containers looking tidy and to encourage continued blooming. As frost becomes more likely, be prepared to cover sensitive plants or bring containers indoors on particularly cold nights.

                In addition to the plants, fall-themed accents can enhance the seasonal appeal of your containers. Consider adding small pumpkins, gourds, or decorative squash to the mix. For a touch of whimsy, add seasonal decorations like mini scarecrows, wooden sunflowers or decorative berries.

                Sprucing up your container plantings for fall in Connecticut can bring a fresh, seasonal look to your outdoor spaces. With the right plant choices, thoughtful arrangement, and a few seasonal accents, your containers can remain a focal point of beauty and interest well into the cooler months. Durocher-Nesta shares thoughts about her favorite fall flower: “Bright and fresh mums bring a smile to my face during a time of year when falling leaves and shorter days mean winter is coming.  They’re one last Hoorah! for the growing season.”
