September is for Late Season Pollinator Plants, Cucurbits, Preparing & Storing your Harvest

"By all these lovely tokens, September days are here. With summer's best of weather and autumn's best of cheer."

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.

  • 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

    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

    Native Plant Highlight: Shrub Dogwoods

    Shrub dogwoods like silky (Cornus obliqua) and red osier (Cornus sericea) and gray (Cornus racemosa ) not only provide food for pollinators in the spring, but they are an important source of food for birds and animals in late summer and fall. They are available at most garden centers that feature native plants and their a cultivars. Many can tolerate some shade and moist soils.

    Vegetable Gardening Resources

    During the growing season, UConn Extension publishes a regular pest alert. Additionally, the New England Vegetable Management Guide offers a lot of information about specific vegetable crops.

    While the target audience for these publications is usually commercial growers, home gardeners can learn a lot from these materials including identification and management of common pests in your veggie gardens!

    If you ever need confirmation on an ID or have additional questions about what you read in these reports, please do not hesitate to reach out to us at the Home & Garden Education Center! We're happy to help your gardens thrive.

          2024 UConn Master Composter Program

          Interested in learning more about composting and sharing your knowledge with others? UConn will be holding its Master Composter program this September. The Master Composter program is a train the trainer program where participants will learn about the various aspects of composted and then donate a minimum of 20 hours volunteer time engaging in outreach projects that may include activities such as tabling at events, giving presentations or working with schools or community gardens. When outreach goals have been met, participants will be certified as Master Composters and receive a certificate of completion. There is a registration fee.

          The 2024 program will be a hybrid program with two in-person Saturday sessions, September 14 & 28 along with two evening online sessions, September 19 & 27 via WebEx. The two Saturday classes will be held at the Middlesex County Extension Center, 1066 Saybrook Rd, Haddam, CT 06438. It is anticipated that two field trips will be offered this fall, also on weekends

          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.
