Summer Weeds

Weeds that appear in hot summer weather are some of the toughest to control. They germinate when your lawn is under stress from heat, humidity, and drought and thrive under these conditions. Some summer weeds are grass-like and are not susceptible to ‘normal’ weed control measures.  Here are some of the weeds you will be seeing during these hot summer months.

Nutsedge

If a bright, yellow-green, grass-like weed is detracting from your lawn’s beauty, there’s a good chance that you’re dealing with nutsedge.  Nutsedge is a yellow-green warm-season perennial. It has upright, grass-like leaves with a glossy upper surface and dull lower surface that emerge from the base of the plant. The leaves are 1/8 to 1/2 inch wide, up to 3 feet long, and have parallel veins with a prominent midvein.  Its flat-topped, burr-like flowers occur July to September and are affixed to the end of a stout triangular stem. It grows in all soil types, especially moist ones, but does not tolerate shade.

Nutsedge is a perennial weed that is hard to eliminate, mainly because it reproduces itself from tubers beneath the soil. If you hand-pull nutsedge, the tuber is usually left behind and will regerminate. Nutsedge grows quickly in low, wet soil. Left unchecked, it will grow as tall as 2-3 feet! Pro-Lawn-Plus’s 5 Treatment program includes a summer weed spray, that helps control nutsedge.  But in lawns with an abundance of nutsedge, it is usually necessary to add one or two supplemental treatments.

Oxalis yellow/purple

Creeping woodsorrel is a spreading perennial weed with a reddish-purple color that frequently roots at the nodes. The three heart-shaped leaves of creeping woodsorrel are nearly identical to yellow woodsorrel. It is sometimes mistaken for white clover. Creeping woodsorrel is most commonly introduced to the landscape through nursery container-grown landscape plants. Once transplanted and established it will quickly escape the landscape beds and invade the surrounding turf. Established creeping woodsorrel is difficult to manage and control because it is also resistant to most weed control products.

Spotted Spurge is a summer annual that produces seeds in 60 to 90 degrees Fahrenheit. From a central taproot, it grows a flat, extensively-branched mat up to 2 feet in diameter. The stems leak a milky sap when broken. Its leaves are small, oval and up to 3/5 inch long. They can be purple-spotted and hairy. Flowers occur June to October and are small and cup-shaped. It is found in thin, drought-stressed soil in hot climates and closely mowed grass. This weed is resistant to many weed control products. To minimize Spotted Spurge, water deeply, aerate your lawn, fertilize in autumn and avoid close mowing.

Lawn Disease

Disease pathogens are present in most lawns and can be triggered when lawns are stressed and weather conditions are right. Typically in warm, humid weather. Prevention is the best strategy for managing lawn diseases. Proper mowing, fertilization, improving poor drainage and increasing air circulation will help fend off serious problems. Fungicides can be applied preventively but will not ‘cure’ the disease. They suppress the symptoms so the disease does not damage the lawn.  Cooler temperatures often help lawns recover from disease naturally.  If by the fall the grass has not recovered the dead areas should be reseeded. Red thread and brown patch lawn disease are the two main diseases affecting Maryland lawns

Brown Patch Lawn Disease

Brown Patch lawn disease occurs in Maryland during warm, humid weather. The combination of daytime temperatures that are over 85°F and nighttime temperatures that stay above 65° F with little airflow leaving the grass moist for over eight hours is the perfect condition for this turf disease. You can identify Brown Patch by its symptoms. Light tan lesions with dark brown edges across the middle or tips of the grass blades are signs you might have Brown Patch. On mornings with abundant dew, you will actually be able to see the signs of the fungal mycelium which look like cottony structures.

Lesions on Grass Blades

It is mainly a problem on improved varieties of Tall Fescue. If you have a variety that is especially susceptible to Brown Patch disease and the ideal environmental conditions are expected for an extended period of time, you might need to have your lawn treated with a fungicide to prevent having to reseed the lawn in the fall. However, if a cold front is expected within a few days to lower the humidity and nighttime temperatures, it may not be necessary to spray. Brown Patch can disfigure a lawn but the disease does not kill the crown of the grass and recovery is possible provided we are not in the middle of a drought.

If you suspect you have Brown Patch disease, avoid nighttime watering if you can. Afternoon and evening showers and thunderstorms on a humid night set up the ideal conditions for Brown Patch disease. Preventative fungicide application can be used to suppress the disease as well. More information on Brown Patch UMD

Red Thread

 Close-up of Red Thread

Red thread disease is a turf disease that likes cool, wet spring weather. It likes temperatures in the 60’s and low 70’s with high humidity and in soils with high moisture content. It is an interesting lawn disease because of the red fungal mycelium (strands) that are visible to the naked eye.

The disease develops in circular or irregular patches from 4 inches to 2 feet in diameter. Affected leaves within these patches are tan or bleached-white in color. From a distance, the patches usually have that reddish appearance, due to the presence of thick, red strands of fungal growth emanating from the affected leaves. It is through the production of these “red threads” that the fungus spreads to healthy plants and survives unfavorable conditions.  After prolonged periods of disease development, the patches may merge to produce large irregularly shaped areas of damaged turf.

Soils that have little or no topsoil and organic matter and don’t hold nutrients are susceptible to Red Thread and Pink Patch as well. Generally, only in the worst cases of these two lawn diseases is it necessary to spray fungicides. There would need to be a prolonged period of cool weather to necessitate control products. A few hot, dry days usually will eliminate the symptoms.  Here is a fact sheet from the University of Maryland that explains the disease in more detail – http://hgic.umd.edu/content/documents/TT-24.pdf

Put a Stop to Grass-Destroying Grubs

Spring is finally here, and along with the beautiful weather and green lawns come the inevitable pests. Per the U.S. Department of Agriculture, pests cause more than 200 million dollars’ worth of turf damage annually! One of the main culprits? White grubs, inconspicuous pests that do their damage under cover. Don’t let your lawn be part of the statistic; learn a little about this pest to limit your chances of serious lawn destruction this season!

Know Your Sneaky Pest

Grubs

Grubs are the larvae stage of several types of beetles, two of which are well-known to most of us as the Japanese beetle and the June bug. Both prefer sunny lawns with moist soil and are especially attracted to lawns that are watered regularly during the hot and dry periods. During mid and late summer, the beetles are ready to lay their eggs underground, leaving them to hatch into young grubs amongst the grass roots. This allows the hungry little grubs to feast on your lawn’s succulent roots. What’s good for the grubs’ growth is detrimental to your lawn! They continue feasting through the fall, and that’s when they do the most damage. As winter approaches, they dig down as deep as one foot, escaping from the cold and becoming inactive for the winter. In the spring, they become active again, and continue to dine on your lawn’s roots. This seasonal cycle continues for three years until the grubs reach maturity. They then become beetles and fly into your garden for a different type of meal, and so the cycle continues.   

Evidence of Grub Damage

If you have wildlife (such as racoons and skunks) digging up your lawn at night, they may be after a yummy snack of grubs. Once grass roots are gone, they don’t grow back, causing dry brown patches of grass. These brown grass areas may feel spongy when you walk on them. You can investigate further by checking the root zone of the sod. Peel back the sod: if it lifts easily, that’s never a good sign, but it may not mean you’re infested with grubs. You’ll need to look for them closely; they’re white and about a half-inch in length with a dark head and legs, and when disturbed they curl into a C-shape. If you find one or two just below the lifted sod, go a little further, digging down another one to two inches. If you find more than three or four grubs within a square foot area, your lawn is infested, and you’ll need help! Once you see the damage, it’s far too late to control. Additionally, the damaged area will not recover because the root system is dead.

Successfully Treating a Grub Infestation

You found grubs, so now what?  Many homeowners attempt to treat the problem themselves, with varying degrees of success. The process can be quite demanding; treatment of grubs is ongoing, not a one-and-done pesticide application. Treatments applied by professionals tend to be much more successful, and there are various pesticides that can be used. Our licensed and experienced professionals know lawns and the pests that infest them. You can rely on ProLawnPlus to choose the correct treatment for your lawn, and we always keep your children and pets’ wellbeing in mind.

PLEASE NOTIFY US IMMEDIATELY IF YOU WANT TO CANCEL OR CHANGE YOUR PROGRAM

OTHERWISE, WE WILL BEGIN SERVICE ONCE THE WEATHER PERMITS.

As you know, 2018 was one of the wettest years on record in the Baltimore. This made it very challenging for anyone who does outside work to complete it in a timely fashion. We had an overwhelming demand for fall seeding in 2018 and because of the weather, we had many days when we could not get our aeration and seeding equipment on lawns. In the future, we will be trying to get our seeding sold earlier in the year so we can schedule them in advance and meet the demand. If you are not already scheduled for aeration/seeding and think you will want it done this fall, please let us know so we can give you a price and get you in the schedule. We are generally booked for seeding by August 15th.

In addition to aeration/seeding, we offer a Mosquito Control Program, a Flea & Tick control to help prevent Lyme Disease and other tick-borne illnesses, Organic Root Stimulant to help improve root development, Perimeter Pest Control to help protect your home from insect invasion and a Tree & Shrub Program. Please call our office to speak to our knowledgeable staff or visit our website (www.prolawnplus.com) for more information or a free estimate.

Please note that on our website, you can pay your bill, set up auto-pay, see what services you have scheduled, refer friends or send us a note.  Click on the tab that says, “Log In To Your Account” and set up your account. We appreciate any referrals you give us. As a show of our appreciation, if any of your referrals sign up with us, we will credit your account $25.00. Also, the customer you refer would get a $25.00 credit off of their first treatment.

Again, if you have any questions about what program(s) might be best for you, please call or email us. Be assured that our goal is to provide you with a beautiful lawn and/or landscape by giving you the best possible service in a professional manner using the safest materials possible.

Very Truly Yours,

Mosquito Control

Nothing interrupts a pleasant evening quite like a mosquito buzzing around your ear. Mosquitoes are certainly annoying, and their bites can be aggravating – but they can also carry West Nile or Zika Virus, which makes them a more serious health and safety concern.

The mosquito has quite an awful reputation. It has been called the biggest killer on the planet and the most deadly animal in the world. With just one bite it can cause great havoc by spreading devastating illnesses like West Nile Virus, Encephalitis, Malaria, Chikungunya and even Heartworm in pets.

These threats are becoming more and more of a concern locally. WBAL and other news outlets have done stories like this one discussing the pests and health risks associated with them.

YouTube ProLawnPlus WBAL Pet Info

 

Our mosquito control program consists of 3-4 sprays to ensure control all season. We start by checking the entire area to eliminate standing water that mosquitoes need to breed. We then apply a barrier spray, using a mist blower, in order to repel mosquitoes in the future.

Call (410) 825-8873 or email us today to request a free estimate for service.

A manager will visit, evaluate your property and leave you an estimate for service.

Lawn Grubs

Grubs have been forced lower into the soil due to the drought conditions we’ve faced late Summer this year. With the recent wet weather, they will return to the surface and start to feed on lawns. Be on the lookout for brown areas in your lawn that are easily pulled up. See video below.

Most grub damage occurs in September and early October. The optimal time to prevent grubs is from late April through mid-July. Curative treatments in August through October are less effective and require immediate irrigation for effective results.

Grubs can cause severe damage to lawns in Maryland. They are the larvae of several species of beetles but the most common here in Maryland is the Japanese Beetle grub. Their life cycle takes one year to complete. The beetles emerge from the soil in late June/early July and feed on trees and shrubs. During July and into early August, they mate and lay eggs in the soil. The eggs hatch in August and begin feeding on turfgrass roots, especially when there is adequate soil moisture.
