Hi William,

I am unable to identify the grass in your photo with any certainty. After reviewing images of a variety of grasses, yours seems similar to both perennial ryegrass and KBG. If you purchased one of the seed mixes listed on Copley's site, even those with high percentages of KBG contain both perennial ryegrass and fescue. I would check with Copley before taking any action. You might also contact your local OSU Extension Office <personal data hidden>

As to controlling grass/grassy weeds in the lawn, here are a couple of links with more info about lawn maintenance and repair.

The growth on your azalea is lichen - not an insect, but the result of a symbiotic relationship between a fungus and an algae. Lichen do not damage their host except in rare and extreme circumstances. In fact, the appearance of lichen on trees and shrubs is often an indication that the host plant is already in distress due to other factors such as age, uneven moisture, lack of nutrients, etc. Azaleas become attractive hosts when they are planted in the sun and/or their leaves thin and let more light into the branches. Controlling lichen is not necessary to maintain plant health, but if the appearance is unaesthetic, they can be physically removed by simply scraping them away.

I hope this information is helpful.
