Mercury and Venus will begin the first part of the month in the constellation Leo, the rest in Virgo. Until the end of the month they will be in the glare of the Sun. On September 30 they could be visible in the West about 30 minutes after sunset. Venus at -3.9 and Mercury at -0.28 magnitudes.
Mars also in the glare of the Sun most of this month. Any view of it will be 45 minutes before sunrise towards the end of the month with magnitude of 1.78.
Jupiter is in Ophiuchus, 25 degrees up from the horizon, South to Southwest most of the evening, Will be hard to miss as its been most of summer, it magnitude this month will range from -2.22 to -2.04. On September 4 the moon Io’s shadow will begin its transit across Jupiter’s face beginning at 9:24 PM. Make it a challenge!
Saturn will be in Sagittarius where it’s been for a while. It is easily found by the handle of the “tea pot”. This month, its rings are tilted 25 degrees to our view from Earth, with 99.8 illumination the view should be thrilling. Its magnitude will range from 1.21 to 1.35.
Note: With both Jupiter and Saturn visible as they, a line you envision between them would be a segment of the ecliptic!
Uranus is in Aries rising in early September around 10 PM and progressively earlier until it rises around 8 PM by the end of the month. On September 17the Moon will be around 5 degrees too bright for the 5.7 magnitude planet. Best wait for a moonless night to take a look.
Neptune is in Aquarius and will be in opposition the night of September 10. You may use the nearby naked eye star Phi (Φ) Aquarii as a guide.
