Greetings!
Summer has arrived and boy is it hot! The temps soared into the 90's the last couple of days and Monday was our very first day where the heat indices surpassed 100�. And how about this crazy wind? The heat and wind are a desiccating combination. I keep hoping the wind will blow some rain in our direction. A 40-50 percent chance of the wet stuff late tonight into tomorrow. It had better rain tonight because there is little to no chance of rain forecast for the next seven days. UGH!
I know it is the first day of summer but have you noticed the late August plants in bloom? Rose of Sharon (photo), sedum Autumn Joy and yes even mums! This has been a wacky growing season as the warmer weather has hurried everything along by about 4-6 weeks. I was surprised to find fresh corn at the Overland Park Farmer's market along with delicious tomatoes, peaches and almost anything else you desired. The fresh vegetables and fruits were abundant for all of us eager buyers. So I wonder, if most of our late blooming perennials are in bloom now what will we have to look forward to in August and even September?

Beat The Heat...
Looks like we're getting a much needed break from the oppressive heat - at least for a few days. When the heat returns (and it will
probably this weekend) make sure you're practicing safe gardening. Here are some tips to help you beat the heat:
- Tasks that occur outdoors in sunny areas should be done in early morning or late afternoon whenever possible, not during the midday heat. Most watering, pruning, dead heading, etc., is better for plants when done in early morning. Many chemicals, especially insecticides, are better applied late in the day when the wind is down and beneficial insects are not present.
- Allow yourself to acclimate to the heat slowly. Over a period of a week or two, gradually increase the amount of time spent in hot, still areas or in direct sun.
- Be sure to stay hydrated, drinking as many liquids as possible. Don't wait until you are thirsty to have a drink, as thirst is an indicator that your body is already dehydrated. Water is preferred, except when heat cramps occur (then drink a lightly salted beverage like a sports drink). The water's temperature should be cool, not cold.
- Though tempting, do not work in the yard in a tank top or without a shirt due to the potential for sunburn and skin cancer. Wear loose fitting, light colored clothes. Keep the fabric content high in cotton to aid sweat evaporation. Neckbands, headbands, wristbands, visors, and hats can increase evaporation to keep the body cool.
- Lastly, take frequent breaks to reduce the amount of time spent in the sun or heat. After working for an hour, take a break to cool down and have a drink in the shade to reduce the build up of heat stress on your body.

Hey Bud, Get Outta' Here!
One of the most common pests of petunias is the budworm caterpillar. These small green worms appear in late June and July and feed on the flower buds, making small holes in the buds and the leaves. You won't often see the worm itself. Instead, you'll see the droppings, which resemble small, black seeds. Because of their size, removing them by hand may not be practical. If you are so inclined, Dipel, Thuricide, Talstar and Scimitar are reasonably effective insecticides. Sevin and Diazinon aren't effective, because budworms have become resistant to them. If left unchecked, the presence of the caterpillars will cause your petunias to stop blooming.

Trees Shedding Bark...
Trees naturally shed bark as they grow. The amount of bark shed varies significantly from one year to the next and is usually not noticeable. But some trees, such as sycamore (photo), London Planetree and silver maple, shed bark in large patches or strips. During a year with heavy shedding homeowners may become concerned that the tree is sick or dying. Such usually is not the case. Sycamore and London Planetree normally show a bright green color on the branches when the bark first falls off but soon return to normal. Maple reveals an orange color after shedding but it, too, soon returns to normal. There is nothing wrong with the tree as long as the shedding bark simply reveals underlying bark rather than bare wood.

Seen Any Spittlebugs?
The spittlebug derives its name from the white, frothy "spittle" the nymphs produce. Adults are large, black leafhoppers about 1/3-inch long with two red stripes that go crosswise across the back. The eyes and abdomen are bright red. Though the nymphs resemble the adults, they are smaller and wingless. Color varies from yellow to white to orange, but the eyes are always red.
Spittlebug nymphs suck plant juices like aphids, but they remove so much water and carbohydrates that excess fluid is produced. They cover themselves with this fluid and then produce the spittle by bubbling air from the tip of the abdomen into the liquid. The spittle mass helps protect the nymphs from drying and from predators.
Spittlebugs normally do not achieve high enough populations to cause damage. If they do, forcefully hosing the plants several times should achieve the level of control needed.

Timely Tomato Tips...
Tomatoes are growing vigorously now. However, the end of spring and the onset of hot, dry weather can lead to several problems in tomatoes. Tomatoes that experience early vigorous growth often drop some blossoms during the transition to summer weather. Don't worry. New blooms should develop rapidly to replace the fallen ones.
Also, tomato plants may be subject to leaf curl where the leaves roll up from the edges. This is a short-term condition that develops as the tomato is trying to reduce it's leaf surface to allow the roots to develop.

Beware Of Brown Patch...
It's getting to be that time of year that brown patch starts showing up all over the area. This turf disease is favored by warm night temperatures and extended periods of leaf wetness. If you go outside in the morning and the lawn is covered with dew and the temperature is in the high 60s and above, it means that conditions are right for brown patch. During severe outbreaks, the fungus may invade the lower leaf sheaths and crown and kill plants. But in most cases the turfgrass can recover from brown patch. This recovery may take two to three weeks depending on weather.
Unfortunately there is no way to eliminate brown patch from a lawn as it will persist indefinitely in the soil. In almost all cases, the limiting factor for brown patch development is the weather. Although you can't eliminate the fungus, cultural practices - especially irrigation - can help control it.
- Don't water in the evening; instead, water early in the morning. This will help decrease the number of hours the leaf tissue remains wet and susceptible to infection. The frequency of irrigation is not as important as the time of day you do it.
- Don't overfertilize, and certainly don't fertilize when brown patch is active.
- Make sure your seeding or overseeding rates are not too high.

Ozone, Mow Zone...
Small gasoline engines like those found on lawnmowers, weed whackers and leaf blowers lack pollution controls. According to the Mid-America Regional Council the average lawnmower produces as much pollution in one hour as forty late-model cars! Do yourself, and your fellow gardeners, a favor by not mowing on ozone alert days. If you have to mow, try to do it after 7 PM.

Finally...
"In June, as many as a dozen species may burst their buds on a single day. No man can heed all of these anniversaries; no man can ignore all of them."
