Lawn and Tree Tid-Bits from My Ryan Lawn and Tree Expert

Lawn Diseases of Summer
Fungus problems common during summer months

To be sure, watering during the hot summer months is a necessity. Most lawns need 2" of water a week to thrive when it is hot. This should be spread out throughout the week so the turfgrass has the ability to absorb the water, instead of it running off the lawn.

Watering should be avoided during the evening hours, from 4p.m. until 4a.m., to avoid fungal problems. However, the rains that we receive often happen in the evening hours, leaving our turfgrass vulnerable to infection.

Although brown patch is on the decline, pythium blight can become more of a threat because the night temperatures are higher than average during this time. To learn more about brown patch and pythium blight, visit our resource library: Lawn Diseases.

Your RYANPro can apply a preventative fungicide to help protect your lawn against summer fungal problems. The product we use helps prevent both stress and fungus from occurring.

Look out for Yellow Leaves
Iron chlorosis common problem

Some trees, like pin oak and river birch, are commonly affected by a condition called iron chlorosis. Iron chlorosis is caused by the tree's inability to absorb the iron existing in the soil. Look for lighter green or yellow leaves with dark green veins.

If left untreated, trees may lose leaves prematurely or suffer branch and limb dieback. Death can result from severe cases.

If you have questions, or have a tree that needs treatment, give your RYAN Certified Arborist a call. We can provide the tree with the iron it needs by injecting an appropriate mixture of iron and water directly into the trunk of the tree.

Brown Spots in Your Lawn?
Soil Problems may be at fault

New homes are especially vulnerable to hot spots. These occur when there is little good soil and the rocks and cement left over from constructing the new house is left in the lawn and the sod is laid on top. The high heat that we are experiencing will result in the lawn being bleached out.

The best way to fix this problem is to remove the rocks or debris below the turf, followed by reseeding or sodding this fall.

Heavy clay soils, common to older areas of town, can hold water which can also cause brown spots to appear in your lawn.

If you have brown spots in your lawn and are unsure of their cause, contact your RYANPro today.
Sprinkler System Confusing?
Your RYANPro can help.

If you have a sprinkler system, you may be among those who are unsure of how to set them properly. Did you know that a common problem when watering with sprinklers is the length of time?

Drought stress is a common problem during this time of year. People are not watering enough. If you need help setting your system up to meet your landscape's needs, contact your RYANPro. Many of our associates are comfortable helping you set up your system. We also have a referral list of sprinkler companies that we trust. We can refer you to someone who can help set up your system and make sure all areas are getting hit evenly.

Lawn Not Performing Well?
Seeding may be your best option

If your lawn isn't performing to your expectations, consider seeding your lawn to improve the quality of grass. Some cool-season lawns contain inferior grass types that will never perform well. These lawns should be killed-out and reseeded, a process that can begin in August.

If you would like to thicken up your existing stand of turfgrass, consider overseeding with high-quality seed. Your RYANPro can advise you which method is best for you.

If you would like us to assist you with your seeding needs this fall, contact your RYANPro today for a FREE seeding estimate.
