28 July If you have a lawn, use a mulching mower, which allows the finely shredded grass to remain in place on the lawn, so no raking or bagging is necessary. Increase the mowing height during summer’s heat. It is best to remove no more than one third of the leaf blade during each mowing. NANCY JAHNEL If you have a compost pile, keep it moist during dry spells. Make sure to keep a layer several inches deep of dry material on the top to prevent flies. You can also install a perforated PVC pipe in the center of the compost pile to keep it aerated without turning the compost.

The twelve-spotted skimmer is one of 140 dragonfly and damselfly species in Minnesota. They serve as a vital part of the food chain near wetlands, rivers and lakes and comprise an important part of our natural biological diversity. Water conservation tips Jerrid’s Journal: kare11.com/weather Jerrid Sebesta Meteorologist The average high temperature throughout the month is just over 83 degrees. July is known for long, extended hot periods. The most notorious heat wave occurred back in 1936 when the Twin Cities had five consecutive days of 100 degrees or more. During that stretch, the all-time record high for the Metro was reached at 108 degrees! Along with the heat comes the humidity in July. Seeing dew points soar into the 70s is fairly common this time of year. July of 2011 was an exceptionally humid time. Moorhead set a state record for the highest dew point of 88 degrees, nearly unheard of for this part of the country. That same afternoon, the Twin Cities set a record with an 82 degree dew point. How much water does it take to wash your hands, wash a plate or get a drink from a water fountain? Most of us probably don’t know. Americans, in general, have plenty of water whenever we want it. Here in Minnesota, we use an average of 80-100 gallons of water every day. Conserving water can be easy. An inexpensive low flow showerhead can reduce water usage in the shower by nearly a third. Fix those dripping or leaky faucets, and save water. When rain falls, why not harvest all that fresh, free water for your gardens and lawns? One inch of rain on a 1000 square foot rooftop can yield 600 gallons of water. Many watershed districts throughout Minnesota offer rain barrels and rain barrel workshops.

Observations are from the Lake Waconia, Lake Minnetonka and the Twin Cities area unless otherwise noted. First Week of July Rodney Nerdahl Twelve-spotted dragonflies skim over ponds. Cedar waxwings and American robins relish the ripe fruit from red mulberry trees. Baltimore oriole parents bring their young to feeding stations for grape jelly and sugar water. Farmers cut the second crop of alfalfa. Field corn is usually at least waist high and soybean plants are up several inches. The picking of ripe garden red raspberries has begun. Swamp milkweed and black-eyed Susan have showy flowers. Fireflies can be numerous along forest edges from extreme NE Minnesota to the southern counties. Morning Stars Second Week of July During warm spells the surface water temperature of lakes rises into the upper 70s. Water striders Grasshopper skate over surface water. Shorebirds such as lesser yellowlegs and least sandpipers have begun migrating through from the Arctic. Wild blackcap raspberry fruit is ripe and good eating. Garden lilium and clematis vines have extremely conspicuous flowers. Other showy perennials include delphinium, Yucca filamentosa, golden yarrow, coralbells and Maltese cross. Northblue and Northcountry, blueberry shrubs, developed by the U of MN, have tasty fruit that is ripe and ripening. In southwest and western MN and into the Dakotas, the combining of wheat begins. Third Week of July Field corn begins to tassel out and soybeans start blooming. Gardeners pick their first ripe tomatoes. We could be enjoying our first meals of locally grown sweet corn. Common milkweed blooms nicely and there isn’t another roadside plant that can compete with its sweet fragrance. Showy blooming prairie plants include purple coneflower, black-eyed Susan and ox-eye. Great blue heron young are in and out of their nests. Fourth Week of July Now that most other birds have almost stopped singing, the loud house wrens, which are still involved with nesting, add much pleasure with their effervescent singing on hot July days. The first Canada geese are flying. The adults have been flightless since about mid-June when they molted their wing feathers. The young geese are testing their new flight feathers so whole families can be seen in flight. A sound of summer, annual cicadas sing loudly and shrilly; the sometimes pulsating buzzing intensifies with warmth. For various melons, such as honeydew and muskmelon, 86 to 98 degrees F is the temperature range at which the rate of growth and development is the greatest. Wild gooseberry fruit is ripe and ripening. Farmers have begun cutting the third crop of alfalfa. Fifth Week of July Look For: First field corn silking (Carver County) 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 July 15 July 7 July 11 July 17 July 3 July 11 July 16 July 19 July 16 July 14 July 19 Lake surface temperatures over 80 degrees F are not unusual during hot spells. Carolina grasshoppers are on the wing. Eastern bluebirds continue to nest, as these birds nest two or three times during the spring/summer season. Purple martins are observed in flocks, already staging for migration. Common mullein, monarda, white sweet clover, butter-and-eggs, common yarrow and blue vervain all bloom as usual. Wild serviceberries, blueberries, pin cherries and red raspberries are ripe in northern MN. Mercury enters the morning sky on July 9, but is impossible to see until the final week of the month. To see it then, look about five degrees above the east-northeastern horizon 45 minutes before sunrise. Mars and Jupiter emerge from the Sun’s glare a week earlier, appearing a few degrees apart! Look for them between eight to fourteen degrees above the eastnortheastern horizon. Antares 20° Scorpius the Scorpion South CONSTELLATION July 15, 2013 at 10:30 pm Evening Stars Venus can be found about seven degrees above the western horizon 45 minutes after sunset. Saturn appears much higher, approximately 27 degrees above the southwestern horizon when viewed 60 minutes after sunset. Don’t wait too long after sunset to observe Venus; it drops out of sight 90 minutes after sunset. Saturn, in contrast, lingers for more than 3½ hours before it sets. 25 o 20 o 15 o 10 o 5 o “Seven NEW Sisters” Star Cluster CDT Moon-July 3 COMING Moon-July 4 Stars of Taurus Moon-July 5 Mars Aldebaran East-Northeast East July 3 - 5 at 4:30 am C.D.T. July 3 – 5, 2013 at 4:30 am CDT Noon W S Sunset 66˚ N 31˚ E Mars has been absent from the sky due to its close proximity to the Sun. This month it finally escapes the Sun’s glare, climbing into the pre-dawn sky. To see the “Red Planet,” choose an observing site with an unobstructed view of the east-northeastern horizon. Then use the brightest star, Aldebaran, of Taurus’ famous “Seven Sisters” star cluster, and the waning crescent moon to pinpoint Mars. Sunrise SUN DECLINATION July 20 29
