Top Ten Fall Garden Activities

Fall is the Best Time to Renew A Garden

The leaves are turning earlier than usual this fall, which means it's time to switch gears and think about getting our gardens ready for winter and spring. That's right, the best time to think about spring is now. After a season of coddling tender summer crops through heat and rain, cool October temperatures are just the thing we need to expend some energy and clear the way for cooler days. The word "chore" has such negative connotations, especially when fall clean up is such fun. Try some of these outdoor activities, and you'll soon feel invigorated to try a few more. Your garden will thank you for it, now, and six months from now.

Start Small To Accomplish Essentials

Of the many activities that beckon, starting with a few essentials will go a long way toward extending the season and ensuring a beautiful spring landscape. I find that spending just 10 minutes a day doing a little here and there during the week, and then tackling larger tasks on the weekend, allows me to stay on top of the essentials. Here are 10 things we can do to ensure a happy, healthy landscape all year round:

  1. Fall is the best time to plant most trees and shrubs. Cool nights and warm days allow transplants to establish strong root systems before hard frost. Be sure to include fruit-bearing
    native trees and shrubs, such as winterberry holly (Ilex verticillata) and viburnum species, to help sustain wildlife through winter. Water transplants weekly until frost, particularly if the weather is dry. 
  2. Divide perennials that have outgrown their space, such as peonies, lilies, salvia, baptisia and host. 
  3. Replace heat loving annuals with their cool-weather cousins: pansies, flowering kale, johnny-jump-ups (Viola cornuta), and snap dragons (Antirrhimun). 
  4. If a green lawn is important to you, fall is the best time to aerate, fertilize, and seed. I'd rather live with the clover, dandelions, and the bees that rely on them. A "weedy" lawn also means little to no work. The yard will still be relatively green in color, and very "green" environmentally.
  5. Dispose of diseased vegetation, and add the rest to the compost pile. As you clear beds, think about leaving a few dried branches and seed heads, particularly from native plants. They’ll add winter interest and provide shelter and food for birds. 
  6. Take advantage of fallen leaves to add a layer of mulch to your newly cleaned and planted beds. Leaf mulch is high in organic matter, free, and easy to make. It will help moderate soil moisture, temperature, and composition. If you don’t have a leaf shredder, rake your leaves into long, low piles and mow over them. Shredding the leaves helps them break down more quickly. Not enough leaves of your own? Fairfax County offers free, composted leaf mulch ( Take advantage of this wonderful free resource, and your garden will thank you in the spring.
  7. Summer planting, brutal heat, and heavy rain wreak havoc on soil. Replenish nutrients now to ensure healthy spring soil. To figure out exactly what type of soil amendments to add, obtain a soil test kit from your county Extension Office or public library.Soil test kits provide valuable information on soil composition, as well as recommendations on the proper combination of amendments for particular plants.
  8. Plant spring blooming bulbs in late fall, when the ground is cool but not yet frozen. Deer and squirrels dislike daffodils, allium and lycoris. Cover them with sharp chicken grit to deter digging. If you’re preferential to bulbs that critters can’t resist, try interplanting them with a few less appetizing varieties. To achieve an extended bloom period, layer early flowering smaller bulbs, such as glory-of-the-snow, above later blooming narcissus. 
  9. Once the work is done, take time to enjoy late-blooming flowers and foliage. Aster bloomsfrom mid-summer through frost. Native varieties are attractive to butterflies. Japanese anemone is another fall beauty, great for the border, woodland, or rock garden. Native shrubs such as Virginia Sweetspire (Itea virginica)and oakleaf hydrangea (Hydrangea quercifolia) add brilliant fall color between the tree line and the flowers. 
  10. Last but not least, take a long look at your landscape, noting any gaps or failed plants. Take note of color and texture. Now it's time to curl up with a  good garden design book and think about how to fill those gaps next spring!

Take Action to Understand and Ban Neonicotinoids

Neonicotinoids are a class of insecticides that are widely used around the world. Initially, thought to be less damaging to birds and insects, large-scale scientific studies ultimately showed that the neonicotinoid residues absorbed by plant tissue infected pollen and nectar. Neonicotinoid use has been linked to honey bee colony collapse disorder, as well as die off in other species. Increasing concern about widespread ecological damage led European countries to ban several pesticides containing neonicotinoids, but the U.S. has not yet done so. 

On Tuesday, the White House Task Force on Bees will report on proposals. Monsanto, Bayer, CropScience, and Syngenta want to retain the use of this dangerous substance. There's a campaign on Avaaz to get signatures before Tuesday's  meeting of the White House Task force. 

We have no time to lose -- members of the White House's bee task force will report with proposals on Tuesday. Already 2.5 million of us have backed this campaign. Let's race to send messages to the heads of the task force before Tuesday's meeting. This is not just about saving bees, this is about our survival. Click to send a message now:

How to Use the Last of The Season's Tomatoes

Tomatoes are taking over the house,
but they're not ripening on the vine.
Fall is officially here. Shorter days and cooler nights take their toll on sun-loving crops, like tomatoes, okra, cucumbers and squash. Gardening in a small space means that when crops slow way down, it's time for them to move out and make space for those that relish the current season.

It's always a sad day when I pick the last tomatoes, but also something of a relief. Relatively cool weather and consistent rain resulted in the best harvest in recent memory. Working through a bumper crop of nearly everything is both joyful and time consuming. Nevertheless, I won't let a single tomato go to waste. Underripe tomatoes quickly mature in a sunny window, where temperatures are steadily around 70 degrees. Here are few tips for preserving and using the last of the pomme d'amore - apples of love:
Greenish tomatoes will ripen in a sunny window,
when outdoor temperatures begin to fall. 

Dry Tomatoes In The Oven

Nothing says umami like a chewy, sun-dried tomato. However, leaving tomatoes in the sun to dry will only result in unwelcome guests chowing down on what is rightfully yours and those whom you chose to feed. Tomatoes are easy to dry in the oven, and the resultant delicacies will store in the freezer for several months. Any type of tomato can be dried, but I like to use 'Roma' varieties that have little pulp. 
Sliced 'Roma' dry easily
in a warm oven.
  1. Pre-heat oven to 170 degrees, or use your oven's lowest temperature setting.
  2. Spray a baking sheet with olive oil. 
  3. Slice the tomatoes about 1/4 inch thick and space them evenly on the baking sheet.
  4. Spray the tomatoes lightly with olive oil.
  5. Sprinkle salt and pepper to taste. Add some dried herbs, if you like.
  6. Bake for about 8 hours. 
  7. Tomatoes will be leathery and flexible when ready. 
  8. Store in freezer-safe bags for up to 3 months. 
  • Use dried tomatoes on pizza.
  • Combine them with rice and toasted pecans for a delicious side dish.
  • Mix them into salads.
  • Pizza with sun dried tomatoes,
    olives, basil, pine nuts, and mozzarella.
    Dried tomatoes will feel leathery. 
  • Share your favorite way to use them!

Prepare and Store Tomato Sauce

  1. Collect the last of the tomatoes onions, peppers, basil, fresh thyme, rosemary, and garlic the farmer's market or your garden. 
  2. Dice vegetables and put them into a crock pot.
  3. Add a teaspoon of salt, a tablespoon of honey, and a dash of red wine. 
  4. Set the temperature on low for 8 hours. 
  5. Dinner is ready! 
  6. Store the rest in freezer safe containers for up to 3 months. 
    Select fresh, seasonal ingredients.

    Store tomato sauce in freezer-safe containers.

Native Plants for Northern Virginia Resource and Publication

The Plant NoVa Natives campaign recently released the publication, Guide to Native Plants for Northern Virginia. Why plant natives? Flora that are indigenous to a region evolved to accommodate and benefit from the wildlife that is also indigenous to that region. Native plants grow easily in the soil they've inhabited for centuries, if not millennia. This means fewer pesticides and less need for supplemental water and fertilizer.

Development endangers native species, which often come to be categorized as weeds. Native clover is a prime example of a beneficial plant that got a bad rap when homeowners longed for ever-green grass. Lawn herbicides knock out native clover, along with crabgrass and other noxious weeds. However, white and purple clover are essential nectar and pollen sources for bees.

The plight of the Monarch butterfly is well-known by now: development caused near elimination of the milkweed, the Monarch's only host plant. Recognition of the value of native plants, and their intrinsic beauty, is slowly restoring the acceptance and encouragement homeowners and gardeners need to grow long overlooked "wild" flowers. Hopefully this beautiful publication, which is available online and filled with gorgeous photos and resources, will encourage local gardeners to go a little wild in our own backyards.
