October in review
October or August 3.0 …. I am not sure which month we just turned the page on but it was not our normally pleasant weather for October. Furthermore, after a year of generous rainfall, we fell in to a mini drought. Even though it was only 45 days without rain the heat really burned up the unirrigated turf. The most frustrating part of the past month was that we were all teased by some nice cool fall weather back in September. The cooler nights and then dry weather put a halt to most of the growth of our turf grasses, but it also made the weeds go reproductive. So every time a lawn was mowed you where mostly just knocking down seed heads and very little else, but then the seed heads came back within days.
What to expect in November
Last month I said you “you can depend on a reprieve from the heat of our summers” about October and that turned out to be a lie. So, I will just say I hope November is cooler and it’s already starting out wetter than the preceding month.
Home gardeners, again I led you astray about getting fall/winter crops in last month. The good thing is you can try again since most of those plants are directly sown from seed into the garden. If you did get some plants started in October hopefully, they made it through to November
Normally, November would be the month we expect to see mowing frequency reduce. The growing season for our warm season grasses close with this month. Nighttime temps below 65 degrees F will shut down the Bermuda and St. Augustine lawn grass.
Also, this month it is time to switch out your seasonal color in your landscape beds and freshen up the mulch while you are at it. While we are talking about mulch, lets discuss tree volcanos.
- Use a hardwood mulch, as it breaks down and decays it adds organic matter and nutrients to the soil.
- Think donut instead of volcano when spreading mulch around the tree. Keep mulch away from the trunk by a few inches at the least, larger trees go up to a foot. Do not cover the flare of the trunk if it is exposed, and avoid covering roots that are visible on the surface.
- Mulch should be 2-3” thick total, adding 2-3” of mulch twice a year will create the dreaded “tree volcano” that suffocates the roots and prevents water from infiltrating. Stirring existing mulch around will keep it from forming a crust that is resistant to water infiltration. You can do this a few times a year and it gives you a freshly mulched look.

Action items for this month- repeats from last month but November is the new October
- Fertilization- We need to feed our grass to support root and plant health as the turf prepares for winter dormancy. It is very important we use the correct fertilizer currently. Using some leftover summer fertilizer will cause excess growth and stress the grass when it is trying to store nutrients for the winner. Below is my one and only recommendation.
- Nitro-Phos- Brown bag- Fall Special fertilizer
- Weeds- This month we need to get down an application of pre-emergent herbicide. Barricade, Dimension or Pendimethlin are the chemicals that you are looking for, I use “Nitro Phos Barricade”
- Roses- Monthly feedings for roses are still important. Your roses should continue to bloom until the frost. In our area the First frost could be 30-90 days away, but keep feeding until then.
- A fall pruning of your roses is generally a good idea. Do it before putting down fresh mulch to make the clean up easier. Follow the steps here for best results.
Municipal Drainage Happenings
October was the driest month I we have seen this year, and historically it is the second wettest. Turf conditions have rebounded well this year following 3 high stress years with droughts and hard freezes. The past 2 months have put a strain on turf, but I think this year has been 5 steps forward 1 step back at the worst.
Fall fertilization and herbicide are nearing completion for us.
Mowing schedules for most districts will drop back to monthly service on tractor-maintained areas and from weekly to every other week for shortgrass. However we will keep an eye on this, with a good shot of rain at the beginning of November we could see turf growth take off especially if the weather remains in the 80s during the day and above 65 at night.
