“Vines for Your Landscape”

Please join the Lincolnshire Garden Club as they get their new program year off to a very “vine” start! Vines can serve many purposes in the landscape. They can soften architectural lines, hide or enhance part of the yard, and add height to a small garden. We’ll learn about a number of different vines that will grow well in northern Illinois, and explore the ornamental features, culture and uses of these vines.

Wow---where did the summer go?  With the heat and the mosquitoes, my gardening days were at a stand still!  Linda Berryman, however, put her time to good use formatting a terrific 2010-2011 program year.  I can't wait to get started.  I am looking forward to seeing all of you and hearing about what you did over your summer vacation.  September 23rd is just around the corner




EDITOR’S NOTE – Several articles in this issue do not list bylines for their authors or contributors.  That is due to a mistake on my part.  I transferred the articles to a folder to save them for upcoming issues, but neglected to note the sources. Please accept my apology for this and if the authors of these articles will let me know, I will give credit in future issues.




“Truth or tale? When certain plants bloom, is it time to do certain garden tasks?”


That question was raised in the June/July 2010 issue of Horticulture Magazine. Their answer was, “There is merit to those old sayings; they stem from something called phenology. Phenology is the study of plant and animal activities and when they occur each year.”


The article went on to say that bloom or leafing times are often related to temperature. Thus, to know when to plant, prune, fertilize, and control pests can be related to what indicator plants are doing. The list of indicator plants and actions is a good one:


When (the indicator)

    Then (time to plant)

Catalpas and mock orange bloom

    … cabbage and broccoli (for fall harvest)

Bearded iris are in bloom

    … peppers and eggplant

Crabapple and wild plum are at     budbreak

    … eastern tent caterpillars are hatching (control them now)

Crocus bloom

    … roses

Daffodils begin to bloom…                     

    … peas

Dandelions start to bloom

    … spinach, beets, and carrots

Daylilies begin to bloom …

    … tomatoes and peppers

Dogwood reaches peak bloom and lily-of-the-valley blooms…

    … tomatoes and early corn


Lilac flowers fade …

    … squash and cucumbers

Lilac is in full bloom …

    … beans

Lilac leaves are the size of a mouse’s ear…

    … peas, lettuce, and other cool-weather crops

Maple leaves start to unfold

    … perennials

Q. I was wondering what you can tell me about cottony maple scale. I have it on my silver maple tree. I am finding out that there is a large outbreak in northern Illinois this year. Many people are suffering from this with what appears to be sap falling from the tree. My whole yard and house is covered with this sap which I found out is really called "honeydew." It is not sap from the tree, it is actually the insect defecating. My friends have this all over their cars. It is very sticky! I took a couple of leaves and the insect to Platt Hill Garden Center in Bloomingdale and they informed me what it was. We cannot even enjoy our yard this summer, it's terrible.

A. An outbreak of cottony maple scale is plaguing northeastern Illinois. Since 1867 the state's residents have reported successive outbreaks lasting for two to three years. Their abundance becomes greatly reduced when natural predators, including a number of wasps and fly parasites are present.

Silver maple and box elder are the primary hosts of cottony maple scale. However, infestations may be seen in other maples, white ash, hackberry, dogwood, beech, apple, oak, black walnut, linden, elm, black and honey locust as well. As they overwinter, cottony maple scales take the form of small, brown, flattened 1/8-inch long scales which attach to the bark of twigs and small branches. By spring the insects have developed into mature female scales - brown, roundish and about 1/4 inch in diameter, which look like tiny army helmets or turtle shells. During this time, the mated females produce a white egg mass, or "cotton," in which the eggs are embedded. The infected branches and twigs with the egg masses and the attached female look as if they have popcorn attached. In mid July the eggs hatch into reddish-brown crawlers which move from the branches and twigs to the leaves where they feed along the midrib or veins. By late summer, mature winged males mate with immature females and soon die because they are not able to feed. Before the leaves drop in fall, the immature females move back to the twigs to overwinter.

Host trees become damaged if there are heavy scale populations causing dieback of branches and twigs. These insects feed on plant sap and excrete a thin, syrupy liquid called honeydew. The honeydew often attracts colonies of sooty mold fungi, which gives leaves, twigs, and branches a blackened, sooty appearance. Heavily attacked trees may drip honeydew on to the ground where it becomes a nuisance when it coats vehicles, furniture, sidewalks and toys.

There are several ways to control cottony maple scale. Mother nature can lend a hand if you allow natural enemies such as wasps and fly parasites along with natural predators such as various species of lady beetles to help. Outbreaks generally build up over a period of 4 to 5 years on average and then disappear due to natural enemies and changing climatic conditions. Use of a dormant oil spray during the tree dormant season is estimated to kill about 90 percent of the overwintering cottony maple scales and is perhaps the best option for control. These should be applied on a day when the temperature stays above freezing for 24 hours after application. Use of dormant oil during this time also eliminates the risk of killing off beneficial insects.

If trees are young and unestablished, stressed or have heavy infestation, a crawler spray may be applied to prevent dieback and decline. Sprays should be applied in July when young crawlers are present on the leaves.

For more information on cottony maple scale, refer to the following publication from the University of Wisconsin Extension




Annually, the Perennial Plant Association (PPA) nominates four plants and PPA members vote for their favorite. It uses four criteria to come up with nominations:


1.   Suitable for a wide range of climates.

2.   Low maintenance.

3.   Easily propagated.

4.   Has seasonal interest in multiple seasons.


Winners from the past 15 years are the following:



Baptisia australis


Hakonechloa macra ‘Aureola’


Geranium ‘Rozanne’


Nepeta (Catmint) ‘Walker’s Low’


Dianthus ‘Firewitch’


Helleborus x hybridus


Athyrium (Japanese Painted Fern) ‘Pictum’


Leucanthemum (Shasta Daisy) ‘Becky’


Phlox ‘David’


Calamagrostis (Feather Reed Grass) ‘Karl Foerster’


Scabiosa ‘Butterfly Blue’


Rudbeckia (Black-eyed Susan) ‘Goldsturm’


Echinacea (Coneflower) ‘Magnus’


Salvia ‘May Night’


Penstemon digitalis ‘Husker Red’


Astilbe ‘Sprite’




Efficiency: Light accounts for only 3% of the energy used by an incandescent bulb—the rest is released as heat.  A CFL bulb is about 18% efficient, or 5 to 8 times more efficient than an incandescent.


Cost Savings: Replacing a 75 W incandescent with a CFL bulb can save you over $22 per year in electricity. You can pay off the purchase price of the bulb in about one month. A household that invested $90 in changing 30 fixtures to CFLs would save $440 to $1,500 over the five-year life of the bulbs.


Longer Bulb Life: The average rated life of a CFL bulb is 6000 to 15,000 hours. The average rated life of an incandescent bulb is 750 to 1000 hours--an 8 to 15-fold increase!  Flipping the lights on and off will reduce the life of a CFL bulb.


Wattage Equivalents for CFL and Incandescent Bulbs


Incandescent                                  CFL


40 watts                                   9-13 watts

60 watts                                   13-15 watts

75 watts                                   18-25 watts  

100 watts                                 23-30 watts  

150 watts                                 30-52 watts 


Mercury and CFL Bulbs: Mercury is highly toxic and small amounts (4 milligrams) are used in each CFL light bulb.  If cleaned up properly, a broken CFL bulb will release only 1.2 mg of mercury, about the same amount as you would consume if you ate two cans of tuna fish.

7-Step Clean Up if You Break a CFL Bulb

  Carefully scoop up glass fragments and powder using stiff paper or cardboard

  Place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.

  Use sticky tape, such as duct tape, to pick up any remaining small glass pieces and powder.

  Wipe the area clean with damp paper towels or disposable wet wipes

  Place towels in the glass jar or plastic bag.

  Do not use a vacuum or broom to clean up the broken bulb, wear disposable gloves if you have them, and wash your hand afterward

  See government's Energy Star page for more clean-up tips.
