Even though we saw a deluge of rain showers recently, it had been an abnormally dry September and plants are stressing from a lack of water. After a couple of years in a row, the lack of water is adding up to create even more problems for plants, trees, and grass.

Deciduous plants such as maples, sweetgum, and oaks, show water stress by dropping leaves, turning colors early, or dying from the top down.

Evergreens are especially affected by drought.  One day they are green and healthy, the next day they are dead.

Drought conditions can severely affect the health of a lawn. Signs of drought include discoloration, blade curling and wilting, thinning and patchiness, slow or no grass growth, weed growth, dry crunchy grass, visible footprints on the lawn, and cracked soil.

Stressed plants are more susceptible to insects, diseases and other traumas like heat. They will not thrive. With this year being so hot and dry, foliage is extra stressed. Watering now is the best way to help them out.

Knowing the plant’s characteristics, hopefully, ensures that they will be watered properly. Watering needs to be done so that it reaches the root ball on new plants. Feeder roots are usually in the top 18” of soil. Plants that like moist soils will need more than plants that like well-drained soils. Over watering is just as bad as no water!

Right now, all plants need water. Water enough to go through the turf and mulch to reach the roots. Water at the drip edge of the plants where the feeder roots are. The drip edge is the area at the ends of the branches. Do not forget to water under the plant to ensure good coverage.

Evergreens are especially at risk of losing moisture as they constantly transpire throughout the winter. While deciduous plants drop their leaves, evergreens do not drop their needles, so they are always losing moisture. Evergreens are also likely to suffer winter burn if they are too dry. Evergreens can be watered throughout the winter months if the ground is not frozen. Evergreens should be mulched by applying mulch rings around the tree. The rings should be at least 3 feet in diameter and 2-3 inches deep. Leave a 2-3 inches space between the base of the trunk and the inner mulch ring. Trees need to breathe.

If turfgrass is not growing due to drought conditions, the lawn should be mowed less frequently. Never cut more than the top 1/3 of the grass and leave the clippings on the lawn to return vital moisture and nutrition to the soil.  Allow the grass to go a bit brown, irrigating as needed which is preferable. No need to water to saturation and trying to keep a perfectly green lawn. One inch of water a week will keep the grass from going dormant.

Even with the rain remnants of Hurricane Helene, Indiana is still in a state of dryness. Significant precipitation is not predicted for the near future, making proper watering techniques and overall correct plant care essential.

October is from the Latin octo, which means “eight”. The number “eight” is said to be a symbol of wealth, prosperity, peace and fertility. 

What flower bulbs do you plant in autumn? Think daffodils, crocuses, snowdrops, tulips, hyacinths, irises, and alliums. These flowers are call “dormant perennials.” They need the cool, moist autumn soil to awaken them from their dormancy so that they can begin growing roots in preparation for the spring.

Documented evidence of an activity resembling football can be found in the Chinese military manual Zhan Guo Ce compiled between the 3rd century and 1st century BC.

Once the hour of daylight dwindles during autumn and the green chlorophyll in leaves is gone, other pigments come out. Carotenoids give leaves their brilliant yellow and orange colors. Anthocyanins are found in deep red and purplish leaves. The presence of tannins means leaves will turn brownish or tan.

Trying to concoct an artificial substitute for rubber, General Electric engineer, James Wright, combined boric acid with silicone oil in 1943. The result was a gooey, bouncy blob which was not suitable for making tires but became a popular kids’ toy later called “Silly Putty”.

De-thatch and/or aerate your lawn.

Keep plants, especially newly planted stock, well-watered until the ground freezes.

The word "pumpkin" showed up for the first time in the fairy tale Cinderella.

Snakes use their tongues and a special structure in the roof of the mouth called the Jacobson’s organ to “taste” what is around them.
