Is Baking Soda Good For Your Yard
Baking soda can be good for your yard, but it can also be harmful. An infrequent application of a mild baking soda spray can effectively kill fungus and mildew, and harmful grasses.
However, the qualities that make baking soda an effective pesticide will eventually end up damaging your healthy plants as well. Spraying too much, too often, will begin to corrode the plants.
Too much baking soda can begin to effect the pH balance of the soil as well. When the pH balance falls off, then the soil can become inhospitable. This stops new plants from sprouting, and kills well established plants.
As one of the primary components of baking soda is sodium, over spraying can lead to a build up of salt on plants. In the short term this is okay, and will have no repercussions for edible plants, but can be harmful in the long run.
Always check on a small patch first. As a homemade solution you may want to try different formulas to achieve different results. Hardier plants will withstand a greater application of baking soda, where new growth may find it overwhelming.
Spray a small area first to see how the plants react, and adjust the formula as necessary. Take care not to over spray, as too much may damage.
Other homemade options include apple cider vinegar solutions, mouthwash solutions, and milk solutions.

The right pH balance for lawn soils should range between 6.2-6.8, but that doesnt mean they dont need calcium.

Fescue Weed And Disease Control
Fescue is susceptible to certain weeds and diseases that thrive in cool-season grasses. While proper maintenance of your lawn will truly help, some weeds and diseases may already be present in your lawn or may blow into your lawn from surrounding properties.
Fescue Weed Control
Weeds commonly found in fescue grass include goosegrass, chickweed, wild violet, and clover. Some weeds, like chickweed, will grow in the winter while others, like goosegrass, will grow in the spring and summer.
Applying pre-emergent herbicide in both the spring and fall will help prevent these weeds from growing above ground. Depending on the pre-emergent herbicide you choose, you may need to apply 1-2 times in the spring. Only apply pre-emergent in the fall if you will not be overseeding or aerating, as the pre-emergent will prevent new seeds from growing and aerating will render the herbicide ineffective.
If you already see weeds in your yard, it is too late to apply a pre-emergent herbicide. Instead, a post-emergent herbicide should be used to kill clover, goosegrass, and other weeds in your yard. Be sure to use a post-emergent herbicide labeled for fescue grass and the weed you are trying to control or you may damage your healthy lawn during treatment.
Fescue Disease Control
Fungus and bacterial diseases can quickly damage a lawn. Diseases like brown patch, pythium blight, leaf spot, and rust can be found in fescue grass, especially when moisture accumulates in the lawn during warm weather.

Naturalize The Infected Parts With Groundcovers
Some wild plants like dandelions are drought-resistant and hardy. They have better coping skills for dealing with fungus. Planting these groundcovers in lawn areas that are susceptible to fungal infestation will help keep the infection at bay. Its the symbiotic-based relationship between grass and flowers that control the fungus.
Follow these steps when planting the groundcovers:
Step 1: Mark the area you want to plant with flour
Once youve identified which part you want to introduce the groundcover, mark it with flour. Remove the top layer of sod if you want to start planting sooner. Add your layers on top of the grass.
Step 2: Build the layers using a six-sheet newspaper
Spread the newspaper sheets and saturate them with water. This helps it to stay in place as you spread 3-6 inches of compost. For summer months or periods of long dry spells, add some water to the layers to keep it moist.
Step 4: Edge the bed perimeter
Edging the flowerbed perimeter using decorative materials like bricks helps keep turf from spreading into it. The bed may take between three and six months to develop. You can plant the flowers in a pot first, then transplant them when the bed is ready. Youll know its ready if the newspaper or turf is gone.

S To Help Your Lawn Recover From Brown Patch
If you live in the Mid-Atlantic States and Tall Fescue is the predominate grass in your lawn, be on the look-out since this is the time of year when Brown Patch begins to show up.
It has been a wet, humid year and now that the temperatures are beginning to rise, the prime conditions for Brown Patch to develop are in place. These conditions include: night time temperatures above 80 degrees, high humidity and turf that is growing quickly.
Watering at night is an all too common practice for many home owners and creates a breeding ground for brown patch. Watering in the early morning is better. If you have an automatic sprinkler system, set it to start at 3 or 4 in the morning. It is still dark at that time, but the Brown Patch fungi do not have enough time to grow and develop before the sun rises again.
Mow The Diseased Parts
Grass fungus spreads quickly, which is why mowing is a suitable solution to control it. When mowing, pay attention to the infected parts. Remove the grass clippings, fallen leaves, or debris that could be sitting on your lawn. Dont leave the grass clippings as they still carry live fungi that may spread to the rest of the grass.
On the other hand, mowing the diseased parts is only effective if the infestation is still fresh. Prolonged fungus infestation might need other control measures before mowing.

Causes Of Brown Patch
The Rhizoctonia fungus may be present for some time in the soil before it manifests as brown patch disease. The fungus overwinters in the lawn grass or soil beneath in the form of fungal bodies known as sclerotia, and it can survive for years until conditions are right. Rhizoctonia is most likely to cause brown patch during the periods of high temperature and high humidity in mid- to late-summer when night-time temperatures remain above 68 degrees F and daytime temperatures are routinely in the 80s or above. Periods of rainy weather when the air is saturated with moisture also promote the appearance of the disease.
In addition to heat and humidity, the main factors inviting brown patch are excessive nitrogen and irrigation, which means that very lush and green lawns can be susceptible to brown patch. Other causal factors include lack of air movement, poor soil drainage, excessive thatch, and compacted soils, which means that poorly maintained lawns can also be prone to brown patch disease.

How To Apply The Fungicide
Some products might require you to water the lawn and let it dry before applying the fungicide. Others have better results when you apply them during a particular time of the day.
All the products are different so do not imagine that the same rules apply to all of them.
Before utilizing the fungicide, make sure you carefully read the products label and instructions. These should include important details like after which period you have to reapply the treatment, dosage, whether it should be diluted with water , best temperature, and so on.
Depending on the fungicide of your choice, you might also need either a broadcast spreader or a general hose sprayer to apply the fungicide. If you opt for a liquid fungicide that comes into a recipient that should be sprayed by connecting it to the water hose, you wont need any of the tools mentioned above.
Also, when you apply the fungicide, its always advisable to wear safety goggles and gloves and avoid any skin contact. You should also not use the solution near any wells or animal drinking water sources or food.

Fungicides On Fescue Sod During The Summer Months Is A Must For Maintaining A Beautiful Yard
In Lawn Care, Sod Varieties by Palmers TurfNovember 4, 2017
Proper fertilization, mowing and watering helps fescue lawns withstand disease. It is always better to perform proper maintenance to prevent diseases than use fungicides.
Fescue yards are subject to four common diseases, including:
1. PYTHIUM BLIGHT This occurs late in the spring when there are hot days, warm nights and plenty of rain. A white growth will begin at the edge of a dead patch. It is commonly seen on lawns which have had too much seed planted in the fall or spring. Too many new seedlings allow the disease to kill large patches. Fertilizing heavily in the late spring causes verdant growth for the fungus to grow on. Pythium blight can be controlled with fungicides. Controlling it by careful seeding and fertilizer is better.
2. BROWN PATCH This is most common on fescue fertilized when night temperatures are above 68 degrees. The dead sections start small but can grow together. Do not fertilize fescue heavily in summer and irrigate in the late evening. There are fungicides available to help control it. Be sure to read the label and use the rate and timing as instructed.
3. SLIME MOLD This is an amazing disease. It looks like oil has been poured on a table sized area of grass. The fungus grows on blades of grass and is gray then turns black. The fungus does not kill the grass. It can be washed off with a garden hose. No fungicide is needed.
