Is the cold weather killing my "weed patch," or have I been infested with bugs?

Just tell people its a wild plant garden you have been nurturing for ages. Suprisingly most people will believe you

Anyway a lot of grass type plants when they reach maturity start drying off as they set seed

Dig out all big weeds and use a push hoe on smaller ones. In the spring allow weed to germinate and then spray with G360(Roundup ) Weed control will be an ongoing process, we have weeds called Fathen & Dock their seed can remain viable in ground for up to 25 yrs

Dont use pre emergence weed killer as this will affect any seeds you plant and can affect other plants

Dont worry about being a first home owner, all home owners were in their first home once

Its a learning experience and as you are asking shows you are prepared to learn, You will do alright

I have always been an advocate for letting the punishment fit the crime. Maybe instead of the death penalty, this scumbag should have his spinal cord severed and forced to live as a quadriplegic. Of course that still leaves the matter of being shot in the face four times by a .40 caliber at close range and enduring all the surgeries that Officer Gonzalez has had to face. Maybe the death penalty is the best option, but none of that quick relatively painless (by comparison to Officer Gonzalez pain and suffering) lethal injection, or electric chair. The ancient Chinese had a punishment that every day the prisoner had a body part removed, starting with the feet and working upward. The body part was then boiled and fed to the prisoner, so that he slowly ate himself to death. No cost for food to the taxpayers. Cruel and unusual punishment? Not in my opinion.

let it go....if everything else is still growing fine..more than likely the cold spell that hit was lower than the heat that particular plants needs to thrive

what exactly is a weed patch?

if it was cold enough to frost then the frost could have killed them.
